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.
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.
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.
