SECTION 7 

PUMP DISASSEMBLY

 

Tools Required: 

 

3/8" Box Wrench 

 

7/16" Socket Wrench 

 

Adjustable Wrench 

 

Vise equipped with soft jaws  
(such as plywood, plastic or other 
suitable material) 

CAUTION:

 Before attempting any maintenance or repair, disconnect the compressed 

air line to the pump and allow all air pressure to bleed from the pump. Disconnect all 
intake, discharge, and air lines. Drain the pump by turning it upside down and allowing 
any fluid to flow into a suitable container. Be aware of any hazardous effects of contact 
with your process fluid. 

 

NOTE:

 Your specific pump model may vary from the configuration shown; however, 

pump disassembly procedure will be the same. 

 

NOTE:

 Replace worn parts with genuine Wilden parts for reliable performance. 

 

 
 
 

 

 

 

 

 

Step 1 

  Step 2 

  Step 3 

Before starting disassembly, mark a line 
from each liquid chamber to its 
corresponding air chamber. This line will 
assist in proper alignment during 
reassembly. 

  Using an appropriate-sized wrench, 

remove the nuts that connect the inlet and 
discharge manifolds to the center section 
assembly. 

  Next, remove the discharge manifold from 

the pump.
