Grundfos GRUND-96416599 Epdm Gasket Kit Cr(n) 45 64

Product Description

The GRUNDFOS GRUND-96416599 is a 14-piece EPDM gasket repair kit designed for CR(N) 45 and CR(N) 64 vertical multistage centrifugal pumps. Each kit contains a complete set of EPDM elastomer gaskets that restore reliable sealing across pump stages and housing joints. EPDM material provides solid resistance to water and mild chemical exposure, making this kit suitable for potable water, light process, and HVAC fluid-handling applications. Licensed pump service technicians and plumbing contractors install this kit during scheduled maintenance or after identifying a seal failure in a multistage pump assembly.

This gasket kit applies to CR, CRI, and CRN pump models in sizes 45 and 64. Vertical multistage centrifugal pumps in this size range are commonly found in commercial building pressure-boosting systems, industrial water treatment circuits, and large-scale irrigation installations. When a pump in this family develops a leak at stage or housing interfaces, replacing the full gasket set with an OEM-matched kit is standard practice to return the pump to rated performance and prevent recurrence.

Key Features

• 14-piece kit provides a complete gasket set for a full pump rebuild or seal refresh
• EPDM elastomer construction offers reliable resistance to water and mild chemicals
• OEM-matched geometry ensures proper seating in CR(N) 45 and CR(N) 64 pump housings
• Addresses stage seals and housing joint gaskets in a single kit for efficient servicing
• Reduces downtime by supplying all required gaskets without sourcing individual pieces

Compatibility

Fits CR(N) 45 and CR(N) 64 vertical multistage centrifugal pumps, including CR, CRI, and CRN models in sizes 45 and 64, stages 1 through 10.

Installation Notes

Installation should be performed by a licensed pump service technician or qualified plumbing contractor. Before disassembly, isolate the pump from system pressure, shut off the suction and discharge isolation valves, and de-energize the pump motor at the disconnect. Inspect all mating surfaces for scoring or corrosion before seating new gaskets, as surface damage will prevent a proper seal regardless of gasket condition. Follow the pump manufacturer's reassembly sequence to ensure correct stage alignment and even gasket compression.
