Grundfos GF97568412 Mechanical Seal Kit CM5-3 Aqqe Epdm 1.5 Hp

Product Description

The GRUNDFOS GF97568412 is a mechanical seal kit designed for the CM5-3 A-S-A-E-AQQE compact horizontal multistage centrifugal pump. The kit includes an AQQE shaft seal with EPDM elastomer, providing a drop-in service solution for maintaining pump integrity on this 1.5 HP, 115/230V single-phase unit. The CM5-3 platform runs at a rated speed of 3320 RPM and delivers a rated flow of 24.7 GPM at a rated head of 107.5 feet. The pump housing is cast iron, and the three impellers are stainless steel. Replacing the mechanical seal restores the fluid boundary at the shaft and is a standard service task during preventive maintenance or after seal wear is detected.

This seal kit is applicable to the CM5-3 horizontal end-suction multistage centrifugal pump used in residential and light commercial pressure boosting, water transfer, and circulation systems. The CM series is designed for pumping clean water and is NSF61 certified for drinking water applications. The pump uses NPT female threaded connections, with a 1-1/4 inch inlet and a 1 inch outlet, and is rated for an IP55 enclosure class. This kit supports continued operation in systems where liquid temperatures range from -4 degrees F to 194 degrees F and operating pressures reach up to 145 psi.

Installation Notes

Mechanical seal replacement on centrifugal pumps should be performed by a qualified plumbing or pump service technician. Shut off and lock out all power to the pump motor and isolate the pump from the system by closing all inlet and outlet valves before disassembly. Drain the pump casing fully before removing the seal cartridge to prevent contamination and injury. Follow applicable local plumbing codes and the manufacturer service documentation for torque and reassembly sequence.
