Disassembly / Reassembly 

 

Air Valve Disassembly

Tools  Required: 

 

•

 

5 mm (3⁄16")  Allen 

Wrench 

•

 

Snap-Ring  Pliers 

•

 

O-Ring  Pick 

 

CAUTION

:  Before any  maintenance or repair is  attempted, the compressed  air  line to the  pump 

should be disconnected and all air pressure allowed 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 hazardous effects of contact with your process fluid.

 

The Wilden P220/P230 metal pump uses the revolutionary Pro-Flo

®

 air distribution system. A 6 mm 

(1⁄4") air inlet connects the air supply to the center section. Proprietary composite seals reduce the 

coefficient of friction and allow the pump to run lube-free. Constructed  of polypropylene,  the Pro-

Flo

®

 air distribution system is designed to perform in on/off, non-freezing, non-stalling, tough duty 

applications. 

 

 
 

 

 

 

 

 

 

 
 

 

 

 

 

 

 

Step 1

 

 

Loosen the air valve bolts utilizing a 5 mm 

(3⁄16") Allen wrench.

 

Step 2

 

 

 

Remove muffler plate and air valve bolts 
from air valve assembly exposing muffler 

gasket for inspection. Replace if 

necessary.

 

Step 3

 

 

 

Lift away air valve assembly and remove 
air valve gasket for inspection. Replace if 

necessary.
