GP1 Series Pump

Fixed, Two-Piece, Cast Iron, 23-80cc. Displacement.

These truck gear pumps are ideal for operators of light trucks for their hydraulic power needs. The Cast Iron Pump GP1 Series fixed displacement gear pump offers high performance and high power density dues to its two-piece cast iron construction, making it an ideal selection for the Aerial and Material Handling markets.

The GPA/GP1 series gear pumps are available to suit most applications. They are light and compact and can be installed in either rear or side mount configuration thanks to their unique dual port layout.  The smaller GPA series is built with an extruded aluminum housing for minimum weight.  The larger GP1 pumps are built with compact cast iron housings for strength.

The gear pumps complement our heavy duty piston pumps and vane pumps.  The performance and characteristics are ideal for many light and/or intermittent applications, including its famous  reliability, along with being engineered with a long, trouble-free service life.
