Description
Overview:
The Mechanical Seal for Koshin SEH 25H Water Pump (OEM No. 050 842) is a precision sealing assembly designed to stop leakage along the pump shaft and maintain suction and discharge performance. Built from durable, wear-resistant components, it combines metal parts, elastomer elements, and hard sealing faces to withstand continuous contact, vibration, and water exposure. It is engineered specifically for Koshin portable water pumps, providing a reliable fit for the SEH 25H series. By keeping water in and contaminants out, this seal helps protect bearings and other internal parts, reducing the risk of premature failure. It is suitable for routine maintenance or as a direct replacement when a worn seal causes drips, reduced pressure, or loss of prime.
Key Features:
- Direct replacement for OEM No. 050 842 for assured fit on Koshin SEH 25H pumps
- Robust construction for long service life under regular pump use
- Consistent sealing to minimise leaks and maintain pump efficiency
- Corrosion-resistant materials suited to water handling environments
