Installation

1. Use grounded fluid supply lines (G). See 

2. If the inlet fluid pressure to the pump is 

more than 25% of the outlet working pres-
sure, the ball check valves will not close 
fast enough, resulting in inefficient pump 
operation.

3. At inlet fluid pressures greater than 15 psi 

(0.1 MPa, 1 bar), diaphragm life will be 
shortened.

4. For maximum suction lift (wet and dry), see 

See F

1. Use grounded fluid hoses (L). See 

2. Install a fluid drain valve (J) near the fluid 

outlet. 

3. Install a shutoff valve (K) in the fluid outlet 

line.
