Wheeler-Rex 39350 Pump Rebuild Kit

This Wheeler-Rex 39350 kit is a pump repair kit designed for hydrostatic test pumps. It fits models 39300 and 39301 and is compatible with Grainger part number 6GDV5. The kit includes three O-rings and is made from HAWA material. It is intended for plumbers and maintenance technicians servicing these specific pumps.

Maximum Operating Pressure 300 psi

The single specification that decides fitment is the maximum operating pressure of 300 psi. This rating defines the pressure limit the rebuilt pump must safely handle. Verify that your hydrostatic test pump operates within this limit before installation. The kit restores the sealing integrity required at this pressure level.

Thermals Noise and Power Draw

As a static seal kit containing O-rings, this product has no moving parts, electrical components or active cooling. It generates no heat, produces no noise and draws no power during normal use. Performance depends entirely on the condition of the pump hardware it is installed into.
