Parker GP1 – Cast Iron Gear Pump


Parker GP1 pumps are fixed displacement, cast iron gear pumps. Their two-piece cast-iron construction provides high performance and high power density.

They are light and compact and can either be installed in rear or side mount configuration, thanks to their unique dual port layout. They are ideal for aerial and material handling markets. The smaller GPA series is built with an extruded aluminium housing for minimum weight.

Parker GP1 pumps are available in 7 displacements from 23cc/rev to 80cc/rev, with maximum pressures up to 250 bar and speeds up to 2000 rpm.  See the technical details tab for specifications.
