Multiquip 0805404235 Mechanical Seal - OEM Replacement Part

This mechanical seal maintains the critical barrier between the pump shaft and casing on Multiquip water pumps, preventing water from leaking along the shaft during operation. When mechanical seals fail, technicians typically observe water dripping from the seal area, reduced pumping efficiency, or complete loss of prime—making this a vital replacement component for restoring pump performance.

Designed for the QPT405SLT trash pump series, this seal works in conjunction with the pump's check valve system that maintains prime and keeps water in the casing for easy startup. The QPT405SLT features a heavy-duty design with tri-discharge ports (one 4" NPT and two 3" NPT) and dual air filtration to minimize internal wear. Regular inspection of the mechanical seal is essential for maintaining the pump's ability to handle demanding applications where multiple discharge ports may be used independently or simultaneously.

Compatible with the following Multiquip models:

• QPT405SLT
