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.

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).

Figure 8a - Typical installation scheme 5.5. FLUID LINE 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. 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. On some uncontrolled systems the back pressure generated from a closed outlet hose can cause the pump to stop or even reverse operation.

5.6 GROUND THE PUMP AS SHOWN BELOW 5.6.1 For the pump: Use a conductor (for grounding) with a cross-section of at least 1.5 . Connect the conductor to the pump’s leg as shown on Fig. 7, and the other end to the grounding line.

WARNING ! When you are transferring hazardous fluids or the pump temperature is over 60C, operator has to make precautions to drain the fluid. WARNING ! FIRE AND EXPLOSION HAZARD If you are working with flammable fluids, be sure to take precautions around the pump while cooling it.
Page 14
WARNING ! Do not run the pump before you make sure all the adjustments are OK. 6.3. Stopping the pump Cut off the air when the pump is not working. WARNING ! PRESSURIZED EQUIPMENT HAZARD The equipment stays pressurized until pressure is manually relieved.

7.1.2.Re-assembly 1. Clean all the parts and inspect for wear. 2. You can re-assemble the pump in reverse order. Check valve balls must be placed on the cages using their own weight. 3. If assembled differently, the pump does not work. 4.

Figure 13a- Pilot valve repair. 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.

8.6 Troubleshooting PROBLEM CAUSE SOLUTION 1- Pump cycles at stall or fails to hold Worn check valve balls, seats or o-rings. Replace. pressure at stall. Disassamble and clean air valve. Air valve is stuck or dirty. Use ONLY filtered air. Check valve ball severely worn and 2- Pump will not Replace ball and seat.
