Figure 8a - 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.   

4-

 At inlet fluid pressures greater than 15 psi (0.1MPa, 1 bar), diaphragm life will be 

shortened.  

 

5.5.2 Fluid discharge line 

1- 

Use a conductive fluid hose or pipe. The pump fluid outlet is 3”. (f).  

2- Screw the fluid fitting into the pump outlet securely. 

3- 

Install a fluid drain valve at the pump outlet. 

4- 

Install a fluid shut off valve at the fluid outlet. 

 

 
 
 
 
 
 

 
 

 

 

 

CAUTION! 
Do  not  over  tighten  fittings  that  are  used  for 
connection  to  the  pump.  Overtightening  may 
damage the pump.
