    5.0. MOUNTING AND CONNECTION OF DIAPHRAGM PUMP A typical setup configuration is shown in figure 7. Further information and consultation on pump setup can be provided by your Ran Pump distributor. ALWAYS USE ORIGINAL RAN PUMP PARTS AND ACCESSORIES. FAILURE TO DO SO WILL INVALIDATE THE GUARANTEE Pump should fixed firmly to the ground or platform and should be fitted in a perpendicular position as shown in Figure 5.
  • Page 9 5.2. Tightening the bolts before first use After you unpack the pump, and before you use it for the first time, check and tighten external fasteners. Tighten the fluid cover screws first, then the manifold screws. (Refer to Figure 7 for torque figures).
  • Page 10 Figure 7a - Typical installation scheme 5.5. Fluıd lıne 5.5.1. Fluid suction line 1- Use a conductive hose or pipe. 2- Screw fluid fitting into the pump inlet tightly. 3- If the inlet fluid pressure is more than 25% of the outlet working pressure, ball check valves will not close fast enough, result will be inefficient pump operation.
  • Page 11 CAUTION! Do not over tighten fittings that are used for connection to the pump. Overtightening may damage the pump. Caution. It is advisable to install a pressure relief system (bypass line)to relieve high levels of pressure that may occur if the pump is pressurised for a long period when not operating.
  • Page 12 5.7. Ventilating exhaust air You must vent the exhaust to a safe place, away from people, animals, food, and all sources of ignition when pumping flammable or hazardous fluids. Note that when there is a tear on the diaphragm, the media in the pump will be exhausted together with the air. To avoid this exhaust the gas away from the operation environment.

  • Page 14: Important Note

    IMPORTANT NOTE : If the diaphragm pump is submerged in water it is important that the fluid will not enter the air exhaust system. To ensure this please use the special exhaust line with suitable attached hose with hose exit not submerged in fluid.
  • Page 15 6.2 Starting and adjusting the pump 1- Check pump grounding before use. 2- Check fittings to be sure they are tight. Use a compatible liquid thread sealant (PTFE, etc.) on male threads. Tighten fluid inlet and outlet fittings securely. 3- Submerge the suction hose in the fluid. Note: If the inlet fluid pressure is more than 25% of the outlet working pressure, ball check valves will not close fast enough, result will be inefficient pump operation.

    7.0 ASSEMBLY AND DISMANTLING OF PARTS WARNING: Before service and maintenance always relieve the air and fluid pressure. This explanation uses figures defined in part (7.0) line (12) fig. 13b. 7.1. Ball check valve repair Tools required - Torque wrench - 13 mm wrench 7.1.1 Dismantling NOTE: To ensure proper seating, you should change the seats with the ball...
  • Page 17 7.2. Changing diaphragm Tools Required - Lithium-base grease (non-freezing silicone grease) - 13 mm wrench - 24 mm wrench - Torque wrench WARNING! Transferred liquid goes into air chamberof pump when the diaphragm ruptures. Liquid can damage the pilot valve o-rings and the air valve o-rings due to its chemical behaviour.
  • Page 18 7.3 Air valve repair Tools Required - 5 mm allen key - 10 mm wrench - Philips-head screwdriver - Lithium-base grease (non-freezing silicone grease) NOTE: Hold the air valve vertical position if the core is sliding with its own weight in the valve body, valve z-rings need to be changed.

  • Page 19: Periodic Maintenance

    8.0 PERIODIC MAINTENANCE 8.1 Cleaning and storage of the pump Do not let your fluid dry in the pump or in the hoses. It may harm the pump. Clean the pump regularly by pumping a suitable solvent for your fluid until the pump is cleaned. Make sure the fluids you are using are compatible with your diaphragm material.
