Whale Gusher 10 MK2/MK3 Nitrile Pump Service Kit

Regular maintenance can return a Gusher 10 manual pump to service without replacing the complete unit. This Whale service kit provides nitrile replacement components for the Gusher 10 MK2 and MK3 models. It is intended for worn internal parts rather than external plumbing or mounting hardware.

The kit includes a diaphragm, valves, and circlips. These components handle the flexing and sealing work inside the pump as it moves water. Replacing them together is helpful when age or wear has reduced the performance of an otherwise usable pump.

Confirm whether the installed pump is a Gusher 10 MK2 or MK3 before disassembly. Inspect the existing valve seats and pump housing for damage that new soft parts alone cannot correct. The nitrile components are specified for this service kit, so use the correct material when matching the original assembly. A service kit addresses routine internal wear without supplying an entirely new pump housing. Browse more pump parts and accessories at CritPro.
