Why Check Balls Matter in Diaphragm Pumps
Check balls are essential components in a diaphragm pump's fluid path. As the diaphragms cycle, the balls seat and unseat to control material movement through the inlet and outlet valve sections. Worn, damaged, or incompatible check balls can affect valve sealing and fluid transfer.
Replacing the check balls with the correct Graco kit helps restore the intended valve configuration. Always confirm the pump model and existing ball material before installation.
FKM Check Ball Construction
The 25P570 kit uses FKM fluoroelastomer balls for pump configurations specified with this check ball material. Material compatibility should be evaluated against the fluid being pumped, operating conditions, and the complete wetted-component configuration of the pump.
Installation and Maintenance
Inspect the check balls, seats, and surrounding valve components when servicing the fluid section. Clean the valve areas and check mating components for wear or damage before installing the replacement balls.
- Relieve all system pressure before pump service
- Confirm the pump model and check ball material specification
- Inspect valve seats for wear, damage, or material buildup
- Install check balls in the correct fluid valve locations
- Reassemble the pump according to the applicable service procedure
