Pump Disassembly

 

Tools Required:

 

•

 

8 mm (5/16") Wrench 

•

 

5 mm (3/16") Allen Wrench 

•

 

10 mm (3/8") Wrench  

•

 

11 mm (7/16") Wrench Adjustable 
Wrench 

•

 

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

 

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 any hazardous effects of contact with your process fluid. 
The Wilden model P1 has a 13 mm (1/2") inlet and outlet and is designed for 
flows up to 56.8 lpm (15 gpm). The single-piece center section, consisting of 
center block and air chambers, is molded of polypropylene or acetal. All 
fasteners and hardware are stainless steel and the air valve is manufactured of 
brass or high-tech engineered thermoplastic. Its air distribution system is based 
on a revolutionary design, which offers economical reliability and performance. 
The model P1 Plastic is available in injection-molded polypropylene, PVDF and 
PTFE PFA wetted parts. 
PLEASE read all directions before starting disassembly. 

NOTE: 

The model used for these instructions incorporates rubber diaphragms, 

balls, and seats. Models with PTFE diaphragms, balls and seats are the same 
except where noted. 

NOTE: 

Replace worn parts with genuine Wilden parts for reliable performance. 

 

 
 
 

 
 

 
 
 

 
 
 

 
 

 
 
 

 
 
 

 
 

 
 

 

Step 1 

 

Before starting disassembly, mark a line from each liquid 

chamber to its corresponding air chamber. This line will 
assist in proper alignment during reassembly. 

Step 2

 

 

 

Utilizing the 10 mm (3/8") box wrench, start by removing 
the four long carriage bolts that hold the top and bottom 
manifolds to the center section.
