M MATERIALS OF CONSTRUCTION The wetted materials (those parts that contact the solution being pumped) available for construction are Glass filled polypropylene, PVC, SAN, Hypalon, Viton, Teflon, 316 Stainless Steel, PVDF, Ceramic and Alloy C. These materials are very resistant to most chemicals. However, there are some chemicals, such as strong acids or organic solvents, which cause deterioration of some elastomer and plastic parts, such as the diaphragm, valve seats, or head.
M UNPACKING THE PUMP Check all equipment for completeness against the order and for any evidence of shipping damage. Shortages or damages should be reported immediately to the carrier and to the seller of the equipment. The carton should contain: - Metering Pump - Clear Flexible Suction Tubing* - Stiff White Discharge Tubing* - Footvalve/Strainer Assy.* - Backpressure Injection Valve Assy.
. Be careful to check that the voltage of the installation matches the voltage indicated on the pump nameplate. Each pump is equipped with a three prong plug. Always be sure the pump is grounded. To disconnect, do not pull wire but grip the plug with fingers and pull out. Do not use the receptacle in common with heavy electrical equipment which generates surge voltage. It can cause the failure of the electronic circuit inside the pump. 7. Tampering with electrical devices can be potentially hazardous.
INSTALLATION, PIPING AND WIRING The metering pump should be located in an area that allows convenient connections to both the chemical storage tank and the point of injection. The pump is water resistant and dust proof by construction and can be used outdoors, however do not operate submerged. Avoid continuous temperatures in excess of 40°C (104°F). To do otherwise could result in damage to the pump. MOUNTING Typical mounting arrangements are shown in Figures B to E.
3. The pump can be mounted to a wall as shown in Figure D. A wall mount bracket kit is available which includes all necessary hardware to mount the pump to the wall. Mounting the pump other than as shown in Figure D defeats the purpose of the housing drain. Mounting dimensions for the pump are provided in Figure F for reference. 4. The pump can be mounted on top of a solution tank as shown in Figure E. Install chemical pump on the cover.
PIPING 1. 2. 3. 4. 5. 6. 7. Use provided tubing of specified size for connection. Connect tubing securely to prevent leakage of chemical and the entrance of air. Since plastic nuts are used for fittings, they should not be tightened excessively i.e. hand tighten only. NPT suction and discharge valves must NOT be overtightened. Hold fittings in place while adding piping and fittings. NPT suction and discharge valves should only be tightened 25 to 35 in. lbs. (4.46 to 6.25 kg/cm).
WIRING 1. -- Risk of electrical shock. This pump is supplied with a three prong grounding type power plug. To reduce risk of electric shock, connect only to a properly grounded, grounding type receptacle. 2. The metering pump should be wired to an electrical source which conforms to those on the pump nameplate. (Applying higher voltage than the pump is rated for will damage the internal circuit.) 3.
DESCRIPTION OF CONTROLS AND OPERATION INTRODUCTION The pump performs the following functions: Selected Controls - Fixed Rate - External Pulse - Straight Pulses - Pulse Storage - Division - Multiplication - External Current Signal - 4-20 mA - 20-4 mA - Stroke Counting - Timed Operation (intervals) Display Alarms - Circuit Failure - Signal Loss - Full Count - Pulse Overflow - Pulse Rate High Relay Output (one selected at a time) - Relay Off - Pulse Overflow - Stop Function - Repeat Strokes - Current Signal
HELPFUL HINTS You can always get to where you want to go simply by accepting or rejecting choices presented. If you find yourself within a menu where you don't want to be, keep selecting No until you return to the main menu. If you go past the desired selection by mistake, keep selecting No and the pump will take you back to it. If you press an inappropriate button, you will be notified by a message which lasts for several seconds. A partly flashing display requires your response.
EXTERNAL PULSE CONTROL - MULTIPLICATION The pump operates as described previsously except that incoming pulses are multiplied by a value from 1 to 999 prior to actuating the pump and then worked off at a selected stroking rate. For example, at a multiplier of 5 and a stroking rate of 25%, each incoming pulse causes the pump to stroke five times at 25% stroking rate and then stop. During operation, the display shows the present value and the present count on a running basis.
RELAY OFF In all control options the relay remains open at all times. STOP FUNCTION In all control options the relay is normally open and closes while the Stop Function is activated through the stop port. CURRENT SIGNAL LOSS In any Current Signal control option, the relay is normally open and closes while the Signal Loss alarm is in effect. FULL COUNT In the Stroke Counting control option, the relay is normally open and closes while the Full Count alarm is in effect.
PULSE OVERFLOW In the Pulse Storage option, when memory capacity is exceeded the Pulse Overflow alarm is triggered. The pump continues to respond to external signal pulses as if 9,999 pulses were in storage. PULSE RATE HIGH In any External Pulse Control option without Pulse Storage, receipt of any pulses at a faster rate than maximum pump stroking rate, 125 strokes per minute, the Pulse Rate High alarm is triggered. The pump continues to operate at its maximum rate and does not respond to the excess pulses.

POWER All metering pumps are available in 115 volts at 50/60 Hertz, single phase. Optionally 230 volts at 50/60 Hertz, single phase can be provided. Prior to start-up always check to insure that the pump voltage/frequency/phase matches that of the power supply. : If pump is fitted with a PVC pumphead (7th position of model number is “V”. Note: PVC is gray, not black), uniformly hand tighten the four head screws before use (18-22 inch pounds / 3.21-3.93 kg/cm). Periodically tighten after installation.
6. Turn the power on once more and adjust the pump flow to the desired rate (see “Controlling Procedure” below). 7. Always check the calibration of the pump after start-up. It’s best to calibrate the pump under your typical use conditions. STROKE LENGTH ADJUSTMENT M Stroke length can be controlled within 0 to 100% of the diaphragm displacement. (It should be controlled within 20 to 100% for practical use.
The pump can be controlled by three types of input signals. All are fully isolated from AC input power and from Earth ground. The input socket connections are located at the bottom of the control panel face and the signal cords are provided with the pump. Remove rubber plugs to access plug sockets. Stop Function: Operation of the pump can be stopped by an external signal input. When the external signal is input to the stop terminals, the red light goes on and operation of the pump is stopped.
The pump responds to a straight (non-ratio) 4-20 mA signal as follows: (Figure N below shows straight response and response ratioed by 25, 50 and 75%): The pump responds to a 20-4 mA signal as follows. (Figure O below shows straight response and response ratioed by 25, 50 and 75%): The signal cord is provided with the pump and has the following polarity: White = Positive (+) Black = Common Signal input impedance is 187 ohms.
The Signal Level output relay option is via the output signal terminals on the pump control panel. It is designed to provide direct or inverted voltage output signals as shown in figure O. The voltage input must have a high-impedance characteristic and must not exceed 24 VDC. The pump circuit can source or sink a maximum current of 10 mA. The signal cord is provided with the pump and has the following polarity when connected to the pump terminals.
: Before performing any maintenance or repairs on chemical metering pumps, be sure to disconnect all electrical connections and insure that all pressure valves are shut off and pressure in the pump and lines has been bled off. Always wear protective clothing, gloves and safety glasses when performing any maintenance or repairs on chemical metering pumps. ROUTINE MAINTENANCE 1. Routinely check the physical operating condition of the pump.
Refer to drawings in the back of the manual. 1. When replacing the diaphragm, it’s always a good idea to replace the valve cartridges and other worn parts. A kit is available from your supplier with all parts necessary to completely rebuild your pump’s wet end. All your supplier needs to know is the “KOPkit No.” on your pump’s nameplate to supply this kit. 2. Set pump stroke length to 0% and unplug the pump. 3.
TROUBLESHOOTING PROBLEM LOSS OF CHEMICAL RESIDUAL TOO MUCH CHEMICAL LEAKAGE AT TUBING CONNECTIONS FAILURE TO PUMP PROBABLE CAUSE REMEDY 1. Pump setting too low 1. Adjust to higher setting (pump must be operating during the stroke length adjustment). 2. Scale at injection point 2. Clean injection parts with 8% muriatic acid or undiluted vinegar. Also, see Maintenance Section). 3. Solution container allowed to run dry 3. Refill the tank with solution and prime.
PROBLEM PUMP LOSES PRIME LEAKAGE AT FITTING PUMP WILL NOT PRIME PROBABLE CAUSE REMEDY 1. Dirty check valve 1. Remove and replace or clean off any scale or sediment. 2. Ball checks not seating or not sealing properly 2. Check seat and ball checks for chips, clean gently. If deformity or deterioration is noted, replace part with proper material. Resulting crystals can hold check valves open, therefore the valves must be disassembled and cleaned.
