Good To Know
Q: How often should these plungers be replaced in an Interpump pump? A: Replacement intervals depend on water quality and operating hours, but plungers are typically swapped when output pressure drops or visible scoring appears on the surface. Routine inspection every 500 operating hours prevents premature seal failure.
Q: Can these plungers be installed without special tools? A: Basic hand tools and careful handling of the ceramic surface are sufficient, but ensuring the pump head is clean and seals are lubricated during assembly gives the best result. Ceramic components are brittle, so avoid dropping or striking them during installation.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
