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:

 Replace worn parts with genuine Wilden parts for reliable performance. 

 

 
 
 
 
 

 

 

 

 

 

Step 1 

  Step 2 

  Step 3 

Loosen the air valve bolts utilizing a 5 mm 

(3⁄16") Allen wrench.

 

  Remove muffler plate and air valve bolts 

from air valve assembly exposing muffler 
gasket for inspection. Replace if 
necessary. 

  Lift away air valve assembly and remove
