High-pressure, dry self-priming pumps for heavy-duty jobs

PAH Series

Need a high-pressure pump that can handle solids and run dry without a problem? The Gorman-Rupp PAH Series is built for the toughest jobs in construction, industry and mining. These prime-assisted pumps use a compressor/venturi system or a high-flow diaphragm primer to ensure quick, consistent priming. For even more performance, the optional TPAWS system delivers faster and more reliable results- even in the harshest conditions.

These pumps offer full above-ground access, making inspection and maintenance on site fast and simple. With heavy-duty components and proven reliability, the PAH Series is built to last- even when handling abrasive fluids or large solids.

Why choose the PAH Series?

Key features

High head and large solids handling

Delivers high discharge pressure while handling solids up to 4” (102 mm) in diameter- a powerful combination for heavy-duty work.

Fast priming and repriming

Uses either a compressor/venturi system or a high-flow diaphragm primer for fast operation. Add the optional TPAWS system for even quicker and more reliable priming.

Dry-run capability

Oversized, oil-lubricated shaft seals allow continuous dry running without damage.

Removable rotating assembly

Service or inspect internal parts easily—just remove four bolts and slide the entire rotating assembly out, with no need to disconnect piping.

Dual bearing protection

An atmospheric barrier and dual lip seals protect the bearings, increase service life, and allow quick external checks.

Replaceable wear components

No need to replace full castings- just change out the wearplate or wearring to minimize downtime and keep maintenance simple.
