Servicing the pumping section
The three inlet and three discharge valves are identical and can be serviced
without disrupting the inlet or discharge piping using a valve kit available from
the manufacturer. Two kits will be needed to repair all the valves in the pump.
The kit includes new O-rings and a valve assemblies (valve seat, poppet, spring
and retainer all preassembled). Service the valves using the kit as follows:
1.
Remove each valve plug using a 24 mm socket (see Figure 16).

2.
Examine the O-ring gaskets, and replace if needed (see Figure 17).

3.

(see Figure 18).
