Frequently Asked Questions
The priming piston helps with initial fluid intake and ensures air is purged from the pump chamber, helping the displacement pump build pressure correctly.
If the piston appears undamaged and not scored, it can be reused, but replacing during major pump servicing is often recommended for reliability.
Proper functioning of the priming piston contributes to smooth pump operation, especially during startup and fluid intake phases.
Regularly inspect for wear and ensure the pump is properly lubricated and flushed after use to avoid buildup and scoring on piston surfaces.
