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. You must vent the exhaust to a safe 
place.

 

 

 

WARNING ! 
Diaphragm pumps are sold as pump unit only. Installing a control 
device (if needed) is the responsibility of the operator. 
If  the power supply of the pump (compressor) is stopped, the air inlet 
to the pump must be cut off immediately. Otherwise when 
compressor restarts, pump may start unexpectedly.   
Manual operation: If the power supply of the pump (compressor) is 
stopped, operator must cut off the air feed to the pump manually. The 
operator must be informed and warned about this. 
Automatic operation: If the power supply of the pump (compressor) is 
stopped, control unit must cut off the air feed to the pump 
automatically. Installing this system is the responsibility of the 
operator or the owner.

 

 
6.0. PUMP OPERATION INSTRUCTIONS 

 

IMPORTANT NOTE 
The pump has a variable temperature resistance to the transferred fluid. 
The  temperature  resistance  of  the  diaphragm,  balls  and  ball  seats 
defines the temperature resistance of the pump. 

6.1. Flush the pump before use 

Pump is tested with water. Flush the pump with a proper solvent before use if your fluid is affected by 
water. Follow  the instructions in 

Starting and Adjusting the Pump.

  

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. 

4-

 Place discharge hose in a suitable container. 

5-

 Turn off the fluid drainage valve. 

6- Turn the air regulator knob three quarters of a cycle clockwise, and open all bleed-type 
master air valves. 

7-

 Increase the air pressure slowly using the air regulator untill the pump primes. Set air 

regulator to 2 bar pressure. Operate the pump 

slowly

 until it is 

fully loaded

8- Working with thick fluids, operate the pump 

very slowly

 until it is fully loaded. 

9-

 Pump is tested with water. If you need a clean pump in your process, flush the pump with a 

suitable fluid until it is fully clean. Then place the suction hose in the fluid container to be 
pumped. 

 

WARNING ! 
Do not run the pump before you make sure all the 
adjustments are OK.
