Frequently Asked Questions
The pin limits the intake ball’s movement within the check valve, allowing consistent suction and proper fluid flow through the pump.
Yes, when used in supported Graco industrial displacement pumps, it helps maintain smooth intake flow even with heavier materials.
This pin is generally used in larger industrial pumps. Smaller sprayers may use a different intake valve design and should be checked by part number.
Stainless versions may require a different pin. Always confirm compatibility through your pump parts manual.
