Product features

Overview
The Ruhrpumpen GWP is a self-priming centrifugal pump for clean liquids and wastewater containing solids. With its self-priming system and an oil bath chamber for the mechanical seal, the pump can automatically re-prime after air ingestion and tolerate dry-running without damaging the seal. The GWP passes solids up to approx. 3″ (≈76 mm) and is available with ANSI 150/300 flanges (RF/FF), making it a robust choice for construction, municipal, and industrial duties such as (sewage) wastewater and sludge transfer.

Additional Information
The GWP features a closed impeller and comes standard with Inpro/Seal® bearing isolators and double-row thrust bearings to minimize shaft play and extend seal life. A large inspection/service port and back-pull-out service concept reduce downtime. It can be driven by electric motor or diesel engine, and installed above liquid level thanks to its self-priming design
