1. 1.1 Introduction General Description Diaphragm Metering pumps are positive displacement reciprocating pumps that combine the high efficiency of the plunger pump with a sealed diaphragm that prevents product leakage. Each pump consists of a power end and a process end separated by a hydraulically operated diaphragm. Individual pumps will vary in appearance due to various liquid ends, accessories, and multiplexing - however, the basic principles of operation remain the same. 2. 2.
2.
2.2.1 Reagent Head Assembly The term Reagent Head Assembly refers to the pump components that come into direct contact with the process fluid (or Reagent). The typical Reagent Head Assembly consists of the following components: a) b) c) d) Reagent Head Diaphragm Suction Check Valve Discharge Check Valve High flow pump models use disk valves.
2.2.2 Pump Head/Piston Assembly The pump head/piston assembly is installed on the intermediate housing.
2.2.2.1 Push to Purge (PTP) The Push to Purge (PTP) valve is located at the top of the Pump Head. It automatically removes air entrained in the hydraulic system. Pressing down on the button at the top of the PTP overrides its automatic operation. This allows a small amount of hydraulic fluid to bleed from the pump head to the reservoir every stroke. Activating the PTP in this manner helps determine if the pump head is properly primed and diaphragm integrity is maintained. 2.2.2.
2.2.3 Control Assembly The output of the PulsaPro 900 can be controlled by changing how far the piston moves with each pump stroke. The Piston is attached to a rotating cam with a connecting rod. The Control Assembly allows the throw of the cam to be adjusted (see Figure 5). The assembly consists of the following parts: e) f) g) h) i) 2.2.3.1 Hand wheel Threaded Shaft Inner Stroke Adjust Shaft Large and Small Plunger Inner Cam Operation The output of the pump is varied by turning the Hand Wheel.
2.2.4 Gear Reducer Assembly PulsaPro 900 pumps are driven by a standard C-face electric motor mounted to an adaptor that completely encloses a coupling. The motor drives a worm gear reduction that turns an eccentric shaft assembly – converting the rotary motion into reciprocating motion. Figure 6 A single drive assembly can drive up to four Pump/Reagent Head assemblies. This is referred to as multiplexing.
3. Equipment Inspection Check all equipment for completeness against the order and for any evidence of shipping damage. Shortages or damage should be reported immediately to the carrier and your PulsaPro Representative. 4. 4.1 Storage Instructions Short Term Storage of PulsaPro Series pumps for up to 12 months is considered short-term. The recommended short-term storage procedures are: a) Store the pump indoors at room temperature in a dry environment.
5. 5.1 Installation Location When selecting an installation site or designing a skid package, consideration should be given to access for routine maintenance. PulsaPro 900 pumps are designed to operate indoors and outdoors. At a minimum, a covering to protect the pump from direct weather and sunlight is required. External heating and/or the use of synthetic lubricants for the gearbox is recommended if ambient temperatures below 20°C (0°F) or above 40°C (104°F) are anticipated.
5.3 Piping System DISCHARGE RETURN TO TANK FROM SUPPLY TANK Figure 8A All piping systems should include: 1. Shutoff valves and unions (or flanges) on suction and discharge piping. a) This permits check valve inspection without draining long runs of piping. b) Shutoff valves should be of the same size as connecting pipe. c) Ball valves are preferred since they offer minimum flow restriction. 2. An inlet strainer, if the process fluid is not a slurry.
4. A separate system relief valve to protect piping and process equipment, including the pump, from excess process pressures. a) The hydraulic bypass valve (HBV) in the pump is not intended to protect the system. Piping weight must not be supported by valve housings or other portions of the reagent head, as the resulting stresses can cause leaks. If appropriate, provide for thermal expansion and contraction so that no excess force or movement is applied to the pump.
6. 6.1 Equipment Startup Lubrication PULSAPRO 900 PUMPS USE PULSALUBE UNIVERSAL 1HG OIL AS STANDARD FOR THE PUMP HEAD AND GEARBOX. USE OF ALTERNATIVE LUBRICANTS COULD IMPAIR PERFORMANCE, DAMAGE THE PUMP AND VOID THE WARRANTY. 6.1.1 Oil Capacities The approximate amounts of oil required to fill the PulsaPro 900 to the specified level is: Pulsalube Universal 1HG is standard oil supplied with all pumps unless specified. Temperatures +40 – 280 °F Total - Pump Head and Gear Box 25 Gallons 94.
13
6.1.2 Oil Fill The pump is shipped from the factory filled to the proper level with PULSAlube Universal or Ultra. The oil is held within two main reservoirs – the Gear Box (located on the motor end of the pump) and the Pump Head (located on the process fluid end of the pump). The two reservoirs are connected to allow lubricant to flow between them to assure a constant oil level across the entire pump. Two sight glasses provide a visual confirmation of oil level.
Proper Oil Level with pump off FRONT SIGHT GLASS Maximum Oil Level Minimum Oil Level Figure 9B: Pump Head Oil Level – Maximum/Minimum Definition 15
6.1.3 Oil Changes 6.1.3.1 Service Level Definition The recommended oil change intervals are dependent upon the operating environment and level of pump usage, classified as follows: Normal service Clean/dry atmosphere, an ambient operating temperature of 0°C to 40°C (32°F to 104°F), and up to 2,000 annual operating hours. Severe Service Humid atmosphere, an ambient operating temperature below 0°C (32°F) or above 40°C (104°F), and over 2,000 annual operating hours. 6.1.3.
6.2 6.2.1 Startup Output Adjustment When starting up the pump for the first time, it is best to set the stroke adjustment to 0% output and then slowly increase the setting to 100%. This allows you to react to any leaks that may be present in the piping system before they become severe. The PulsaPro 900 uses a hand wheel for manual stroke adjustment. It is mounted on the rear of the stroke adjust housing (refer to Figure 10). The hand wheel can be adjusted at any point from 0 to 100%.
6.2.2 Priming the Pump Head All pumps are shipped with a fully primed hydraulic system. However, during shipping, handling and storage some air may accumulate in the hydraulic system resulting in reduced performance. Generally this air will be automatically purged after a short run-in period. If necessary, rapid purging may be accomplished by: 1. Fully depressing and holding the button on top of the PTP valve while the pump is operating at any stroke length setting above 30%. 2.
6.2.4 Motor Rotation Verifying the proper rotation of the motor a) To verify the correct shaft rotation of the motor you can remove the 3 screws to the access cover or remove the large pipe plug on the side of the motor adaptor housing. This will allow you visual sight of the motor coupling to verify rotation. b) Another way to verify the proper motor rotation is to observe the rotation of the fan on the motor.
6.2.5 Calibration All metering pumps must be calibrated to accurately specify stroke length settings to achieve required flow rates. Figure 11 A typical calibration chart is shown in Figure 11. Although output is linear with respect to stroke length setting, an increase in discharge pressure decreases output uniformly, describing a series of parallel lines, one for each pressure (only two are shown in the figure).
7. Maintenance ALWAYS LOCKOUT/TAGOUT THE PUMP MOTOR BEFORE PERFORMING MAINTENANCE OF ANY KIND. BEFORE PERFORMING ANY MAINTENANCE REQUIRING REAGENT HEAD OR VALVE (WET END) DISASSEMBLY, BE SURE TO RELIEVE PRESSURE FROM THE PIPING SYSTEM. WHERE HAZARDOUS PROCESS MATERIALS ARE INVOLVED, RENDER THE PUMP SAFE TO PERSONNEL AND THE ENVIRONMENT BY CLEANING AND CHEMICALLY NEUTRALIZING AS APPROPRIATE. WEAR ALL REQUIRED PROTECTIVE CLOTHING AND USE PROTECTIVE EQUIPMENT.
7.1 Wet End Removal, Inspection, and Reinstallation IF THE DIAPHRAGM HAS FAILED, PROCESS FLUID MAY HAVE CONTAMINATED THE PUMP OIL. HANDLE WITH APPROPRIATE CARE, CLEAN AND REPLACE OIL IF REQUIRED. DUE TO THE SIZE AND WEIGHT OF WET END COMPONENTS, CARE MUST BE USED TO SELECT THE PROPER TOOLS AND LIFTING EQUIPMENT FOR HEAVY LOADS. Figure 12 PulsaPro Series diaphragms do not have a specific cycle life.
Diaphragm Replacement procedure 1. 2. 3. 4. 5. 6. 7. 8. 9. Disconnect the power source to the drive motor (e.g., lockout/tagout the motor disconnect). Relieve all pressure from the piping system. Close the suction and discharge shutoff valves (refer to Figure 8A). Disconnect piping to the reagent head and drain any process liquid, following material safety precautions from the process liquid manufacturer. Place a pan underneath the pump head to catch any oil leakage from the pump.
7.2 Re-Priming the Pump Head The PulsaPro must maintain hydraulic prime to operate properly. While its Hydraulic System includes several components to protect its prime – the HPV, HBV and PTP – they will not automatically restore hydraulic prime if the oil is drained from the hydraulic chamber (the space between the piston and the diaphragm). This would commonly occur when the diaphragm is replaced for example. This procedure describes how to efficiently re-prime the Pump Head.
7.2.1 Re-Filling the Hydraulic System Use the following procedure to refill the Hydraulic System after Diaphragm/Piston service or extreme system upset conditions: 1. Disconnect the power source to the drive motor (e.g., lockout/tagout the motor disconnect). 2. Check the Pump Head Oil Level (refer to Section 6.1.3 Oil Changes). Restore levels in the Pump Head Reservoir if necessary. 3. Remove the PTP valve from the Pump Head carefully to access the Hydraulic Chamber.
7.3 Check Valves Most fluid metering problems are related to check valves. Problems can be caused by solids accumulation between the valve and seat, corrosion of seating surfaces, erosion, physical damage due to wear or the presence of foreign objects. There are two styles of check valves. Ball checks are used for lower flows. Disk checks are used for higher flows. Figure 14 The ball check valve incorporates a ball, guide, and seat.
7.3.1 Check Valve Removal TAKE ALL PRECAUTIONS TO PREVENT ENVIRONMENTAL AND PERSONNEL EXPOSURE TO HAZARDOUS MATERIALS. 1. 2. 3. 4. Disconnect the power source to the drive motor (e.g., lockout/tagout the motor disconnect). Relieve all pressure from the piping system. Close the suction and discharge shutoff valves (refer to Figure 8A). Loosen the suction valve tie-bar bolts and spring the suction piping slightly to drain any liquid from the reagent head cavity.
7.3.4 Check Valve Reinstallation 1. Reinstall both valve assemblies, taking care to ensure that they are correctly oriented with balls or disks above seats. Refer to Figure 14. 2. Tighten the tie bar bolts evenly, making sure the valve assemblies and tie bar are assembled squarely. Refer to Appendix III for torque values. For best results, always loosen the unions or flanges on either side of the system piping prior to re-tightening the check valve assemblies.
7.4 Hydraulic Performance Valve (HPV) During normal pump operation hydraulic fluid is continually discharged through the automatic bleed valve and may also be lost past the piston seals. This causes the diaphragm to be drawn further back on each successive suction stroke until it actuates the HPV. Once the valve is actuated, oil is allowed to flow into the hydraulic system until the piston reaches the end of the suction stroke.
7.4.1 HPV Removal and Replacement 1. 2. 3. 4. 5. Disconnect the power source to the drive motor (e.g., lockout/tagout the motor disconnect). Relieve all pressure from the piping system. Drain the oil from the eccentric box / pump head by opening the drain valve. Remove the reagent head and diaphragm using the procedure outlined in Section 7.1. The dish plate is held in the pump head by two sealing o-rings. Install screws into the two M4 x 0.
Figure 16 10. Reinstall the diaphragm and the reagent head using the procedure outlined in Section 7.1. 11. Close the Gearbox / Pump Head drain valve and fill with PULSAlube Universal or Ultra hydraulic oil. 12. Re-prime the pump head. 7.5 Hydraulic Bypass Valve (HBV) All PulsaPro Series pumps incorporate a Hydraulic Bypass Valve (HBV). This valve is designed to protect the pump against excessive hydraulic pressure encountered during system upset (it will not limit or regulate system pressure).
the setting is too low the valve will operate on each discharge stroke. This results in decreased pumping capacity and will eventually affect the efficiency of the valve. To check the hydraulic bypass pressure setting, install a gauge and a back pressure valve in the pump discharge line. The gauge must be between the pump and the back pressure valve (for convenience, locate the two as close to the pump as possible).
7.5.2 PTP Removal, Cleaning, and Reinstallation Any accumulation of solids can cause the valve to malfunction. 1. Disconnect the power source to the drive motor (e.g., lockout/tagout the motor disconnect). 2. Relieve all pressure from the piping system. 3. Slowly unscrew the valve to gradually relieve any residual hydraulic system pressure. OIL MAY LEAK OUT FROM AROUND THE PTP VALVE. TAKE APPROPRIATE MEASURES TO CAPTURE AND CONTAIN IT. 4.
7.5.3 Piston Seal 7.5.3.1 General Description The piston assembly has 2 different design structures as shown in Figure 19. With proper maintenance, piston seals should give you years of service.
7.5.4 Piston Removal Piston Removal Procedure: 1. Remove reagent head, and dish plate using the procedure defined in Section 7.4.1, HPV Removal. 2. Remove the nut from the end of the cross head shaft assembly. 3. Set the stroke adjustment setting to 100%. 4. Rotate the Motor by hand (confirm lockout/tag out) until the piston achieves its full forward position. 5. Continue Motor rotation until the cross head shaft is pulled from the hole in the center of the piston assembly. 6.
1. Apply PULSAlube Universal or Ultra hydraulic oil to all the piston assembly components. No matter which piston size you have. For 4 inch pistons and larger please follow these instructions: 1.1 1.2 1.3 1.4 1.5 1.6 1.7 Slide the smaller of the 2 o-rings over the threaded end of the cross head. Install the spacer onto the threaded end of the cross head. Install the piston cup with the outer lip facing away from the cross head.
7.6 Oil Seals 7.6.1 General Description The PulsaPro 900 gear box has seven primary oil seals. Six of these are static o-ring seals. Only one (the Worm Oil Seal) is dynamic and should be serviced at regular intervals.
7.6.2 Motor Adaptor Oil Seal Removal and Replacement 7.6.2.1 Motor Adaptor Removal and Worm Oil Seal Replacement 1. Disconnect the power source to the drive motor (e.g., lockout/tagout the motor disconnect). 2. Attach required lifting device to the motor. Do not put any tension on the pump motor at this time. 3. Remove the four Motor Attachment Bolts from the motor (refer to Figure 24). 4. Open the Access Panel by removing the three Access Panel Screws. Figure 24 5. 6. 7. 8. 9.
Figure 26 10. Remove the four seal retainer bolts and seal retainer. 11. Remove the input shaft oil seal from the input shaft adjustment nut. 12. Lubricate the replacement input shaft seal with silicone grease or PULSAlube Universal or Ultra. 13. Slide the input shaft adjustment nut onto the input shaft and begin tightening. The input shaft adjustment nut should have about .002in (0.05mm) max end play. 14. Install the input shaft oil seal by pressing it into position.
7.7 7.7.1 Stroke Control Assembly Stroke Control Assembly Maintenance The stroke adjust housing has grease fittings that will need to be maintained. (Refer to Figure 27). 1. Disconnect the power source to the drive motor (e.g., lockout/tagout the motor disconnect). 2. To access the grease fitting remove Qty 6 lens cover bolts. 3. Remove the protective lens cover. 4. Adjust the stroke setting from 100 % down to approximately 65%.
7.8 Motor Removal and Reinstallation 1. Disconnect the power source to the drive motor (e.g., lockout/tagout the motor disconnect). 2. Disconnect the motor wiring from the motor. 3. Attach required lifting device to the motor. Do not put any tension on the pump motor at this time. 4. Remove the four Motor Attachment Bolts from the motor (refer to Figure 24). Some European motors will have eight bolts 5. Open the access panel by removing the three access panel screws to expose the coupling.
8. 8.1 Replacement Parts PulsaPro Series KOPkit Program PulsaPro Series KOPkits contain all replacement parts normally used in a preventative maintenance program. PULSAlube Universal or Ultra is available for preventative maintenance programs. Refer to the Equipment Startup section. There is a specific KOPkit for every PulsaPro Series pump model. When practical, each KOPkit is vacuum-packed for extended storage.
9. PULSAlarm Leak Detection Assembly The PULSAlarm leak detection assembly consists of a reagent head, leak detection diaphragm, fill port, and pressure switch and gauge. The reagent head, diaphragm, suction and discharge check valves are the only parts of the pump to contact the process liquid consequently, maintenance is critical to pump performance. Figure 24 A SEALED SYSTEM MUST BE MAINTAINED AT ALL TIMES DURING PUMP OPERATION, WHETHER LEAK DETECTION IS REQUIRED OR NOT.
9.1 PULSAlarm Leak Detection Diaphragm Double, or sandwiched, TFE diaphragms are sealed at their peripheries to an intermediate metal spacer ring. The space between the diaphragms is sealed so that the diaphragm functions in a manner similar to a standard single diaphragm. In the pressure system, the space between the diaphragms is filled with a small amount of fluid. At startup, any excess fluid in the system is expelled through the check valve. Once the excess is removed the system is capped and sealed.
Pressure System Set-up and Priming If the pressurized leak detection system is opened to the atmosphere during maintenance or inspection, the system must be re-primed properly to avoid diaphragm damage and ensure proper leak detection operation and system performance. THE STANDARD FACTORY INTERMEDIATE FLUID IS SILICONE LD. IF ANY OTHER CUSTOMER-SPECIFIED MEDIA IS USED, IT MUST BE COMPATIBLE WITH THE MATERIALS OF CONSTRUCTION. REFER TO THE FLUID MANUFACTURER’S LITERATURE FOR APPROPRIATE SAFETY PRECAUTIONS.
12. If the pump is not already hydraulically primed, remove the PTP valve from the top of the pump head. Using a plastic funnel or similar, slowly pour hydraulic fluid into the pump head cavity until full. The end of the funnel should fit into the small diameter hole at the bottom of the PTP socket – not the larger threaded diameter. The threaded diameter includes a side drain passage that will prevent oil from entering the pump head if used.
9.3 PULSAlarm Leak Detection Diaphragm Maintenance AFTER DIAPHRAGM FAILURE, PRESSURIZED PROCESS FLUID CAN BE PRESENT IN ANY PART OF THE PULSALARM LEAK DETECTION SYSTEM. TAKE APPROPRIATE PRECAUTIONS AND HANDLE WITH CARE.
9.3.1 Leak Detection Diaphragm Removal Use the following procedure to remove the Leak Detection Diaphragm: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 9.3.2 Disconnect the power source to the drive motor (e.g., lockout/tagout the motor disconnect). Relieve all pressure from the piping system, and close the inlet and outlet shutoff valves Take all precautions to prevent environmental and personnel exposure to hazardous materials. Place a suitable container underneath the pump head to catch any liquid leakage.

Appendix I – Piping Calculations Suction Head Requirements All reciprocating metering pumps require a net positive suction head (NPSHR). Refer to Table 1 for the (NPSHR) required for PulsaPro Series pump models. The NPSHR is defined as the pressure required above the absolute vapor pressure of the process fluid at the pumping temperature.
