Weinman WEIN-Q26-395-Y6 Mechanical Seal Hot Water

Product Description

The Weinman WEIN-Q26-395-Y6 is a mechanical seal designed for hot water pump applications. It seats between the pump casing and motor shaft to prevent fluid leakage where the rotating shaft passes through the pump housing. This seal is engineered for use with Weinman close-coupled centrifugal pumps fitted with motor frames ranging from 145JM through 184JM and 213JM through 215JM. Licensed plumbers and pump service technicians handling commercial or residential hydronic circulation and water transfer systems are the primary installers of this component.

This mechanical seal is applicable to hot water service in hydronic heating, building water circulation, and similar pump-driven fluid systems. It is compatible with a broad range of Weinman pump models across multiple series, making it a common replacement part for pump rebuild and maintenance work. Typical installation scenarios include scheduled seal replacement during pump overhaul or emergency service after seal failure results in shaft leakage.

Installation Notes

Mechanical seal replacement on close-coupled centrifugal pumps is performed by licensed plumbers or qualified pump service technicians. Before beginning work, shut off and lock out power to the pump motor and isolate the pump from the system using service valves to relieve pressure. Inspect the shaft sleeve and seal faces for scoring or corrosion before installing the new seal, as surface damage will cause premature seal failure. Follow applicable local plumbing codes and the pump manufacturer service documentation for proper assembly sequence and torque guidance.
