Only a qualified systems integrator should be allowed to design it into a system. The integrator must determine proper plumbing, mounting, driveline and guard components. Improper installation or use could lead to a serious, even fatal, accident.
Good Practice NOTE: These are general guidelines and do not cover all possible situations. It is the responsibility of the system integrator to apply this product properly. Plumbing 1. The inlet pipe should be as short and straight as possible to minimize suction pressure losses. Excessive restrictions at the inlet can cause cavitation resulting in poor performance, noise, vibration, or pump damage. 2. Slope the inlet plumbing appropriately to avoid air pockets. 3.
Guarding PTO Drive Shafts PTO drive systems can be dangerous and when used, additional safety precautions, including guarding, may be required and must be provided by the drive system installer. Roper Pump Company has no responsibility for recommending or providing proper guarding or other safety measures in any particular application.
1. NAMEPLATE DATA Roper Pump Company identifies each pump manufactured by a metal nameplate attached to the pump. This nameplate describes the pump as built at the factory. Copy the nameplate data from your pump in the area provided below. Use this for ready reference when ordering repair parts or when consulting with a Roper distributor or Roper Pump Company about this pump.
• The letter or group of letters (X, LX) indicates direction of rotation and shaft position. The letter (L) indicates low drive unit. If the letter (L) is not used, the shaft will be in a high drive position.
2. MAXIMUM PUMP RATINGS The maximum pressure, speed, and temperature limits for this pump SERIES are shown below. The maximum rating of a pump with a SPEC number may be different depending on the materials of construction. Maximum limits for this SERIES: Pressure 125 psi [862 kPa] Maximum Inlet 125 psi [862 kPa] Maximum Discharge Speed 750 rpm Maximum Temperature Mechanical Seal Pumps: 212°F [100°C] Packed Box Pumps: 250°F [121°C] 3.
4. RECOMMENDED TOOL LIST NOTE: Tools not furnished with pump.
5. DIRECTION OF ROTATION AND RELIEF VALVES There are three types of integral relief valves available. The standard RV, double setting RV, and jacketed RV are all designated by the letters “RV” in the pump nomenclature. The spec number is used to identify which RV relief valve is used. STANDARD RV This relief valve is externally adjustable by means of an adjusting screw located in the center of the relief valve cap. The range of adjustment is approximately 30 psi [207 kPa] to 125 psi [862 kPa].
RECOGNIZING THE RELIEF VALVE Figure 5.2 PROPER PUMP GEAR ROTATION Proper gear rotation is shown on the warning tags attached to the relief valve faceplate. WARNING DO NOT REVERSE ROTATION Reversing rotation of the pump without reversing the position of the relief valve faceplate will cause the relief valve to be inoperable. Discharge pressure will be holding the valve closed instead of pushing it open.
DIRECTION OF ROTATION FOR THE RV STYLE RELIEF VALVE The drawings showing DIRECTION OF ROTATION FOR PUMP CONFIGURATIONS USING THE RV STYLE RELIEF VALVE and position of relief valve with the letter “L” in the designation are for low drive applications (the drive shaft is lower than the side port). All other drawings shown in Figures 5.4 and 5.5 are for high drive applications (the drive shaft is above the side port).
WARNING DO NOT operate a pump with a relief valve that is not positioned correctly. The relief valve will be inoperable. This can allow high pressure buildup on the discharge side of the pump and in the system downstream of the pump. High pressure can cause the pump or any other system component to break or leak causing liquid in the system to escape, resulting in possible injury or death.

15. SHAFT SEALING STANDARD COMPRESSION PACKING One type of shaft sealing used in these pumps is formed ring packing with or without a lantern ring. When using a packed box pump, use formed packing rings. DO NOT use a one piece spiral wrap of packing. Packing rings are available in a wide selection of materials for various applications and temperatures. Previous experience with the pumped fluid is the best guide in selecting the proper packing ring material for your particular application.
The packing gland nuts should first be evenly tightened with a wrench to seat the packing firmly in the stuffing box and against the shaft. DO NOT over-tighten the packing. The gland nuts should then be backed off until fingertight. Connect the flush or lubricate the packing if either method is used. After the pump is started, note the amount of leakage from the stuffing box. If the packing leakage exceeds ten drops per minute, stop the pump and adjust the gland nuts.
10. Push stationary seal face into seal chamber. 11. Position locator ring (60) in counterbore of backplate (6A, B). Make sure antirotation pin (T) engages in slot in back of stationary seal face. 12. Place one square head bolt (G) through each slot in backplate (6A, B) and through each hole in seal retainer (9). Secure seal retainer against backplate using two locknuts (F). 13. Assemble backplate assembly to remainder of pump following correct steps in INSTRUCTIONS FOR PUMP ASSEMBLY, Section 11.
