  Changing Pump Valves 

The Bosworth Company 

Doc M-09-33-111516 

 

Each pump body in the Guzzler G2 

SapPuller 

pump features a pair of 

valves (a total of 4 for the pump).  A valve is fastened between the 
pump body and each of its inlet and outlet ports. 

(Figure 14)

  

 
 
Valves are typically replaced in pairs; i.e., the inlet and outlet valve 
of a given pump body are replaced at the same 

Ɵ

me.   

 
When replacing a pair of pump valves, it is best that 

only one valve 

is removed and replaced before a

Ʃ

emp

Ɵ

ng to remove and replace 

the other valve.

 

 

Removing the Valve 

1.  Disconnect the power. 

2.  Place the pump assembly with the motor 

in a ver

on. 

3.  Remove the inlet manifold by loosening 

the hose clamps holding the manifold to 

the pump 

fl

anges. 

4.  Remove the 6 screws holding the inlet 

fl

ange to the pump body.  

(Figure 15)

  The umbrella 

valve is located between this 

fl

ange and the pump 

body.
