SECTION 7 

PUMP DISASSEMBLY

 

Tools Required: 

 

2 - 5/8" Wrench

 

 

2 - 3/8" Wrench  

 

1 - 1/8" 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:

 The model used for these instructions incorporates PTFE diaphragms and balls. 

Models with rubber diaphragms and balls are the same except where noted. 

 

NOTE:

 Replace worn parts with genuine Wilden parts for reliable performance. 

 

 

 

 

 

 

 

 

Step 1 

  Step 2 

  Step 3 

Please note alignment marks on liquid 
chambers. Use to properly align center 
section with liquid chamber. 

  Utilizing the two 5/8” adjustable 

wrenches, remove bolts that fasten the 
discharge manifold to the liquid 
chambers. 

  Remove the discharge manifold to 

expose the valve balls, valve seats and 
valve seat O-rings.
