HS430S High Pressure Bolted Metal 

 

SECTION 7 

PUMP DISASSEMBLY

 

Tools Required: 

 

9/16" Wrench  

 

Adjustable Wrench  

 

Vise equipped w/ 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 the appropriate-sized wrench, 

loosen the discharge manifold from the 
liquid chambers. 

  Lift the discharge manifold to expose 

discharge valve balls and valve seats. 
Inspect ball cage area of manifold for 
excessive wear or damage.
