2.5PB Series Aluminum Gear Pumps, Up To 20 GPM @ 1800 RPM, Up to 3600 PSI, Up to 3000 RPM

Description & Features

Application	Pumps are stocked with Clockwise rotation. Rotation can be changed by reversing the position of the drive shaft and driven shaft, and rotating the front flange.
Features	All pumps are available as multiple units either of the same or different series. With all sizes, there are options of shafts, flanges and ports as for European, German and American standards. Salami gear pumps offer high volumetric efficiency by innovative design and accurate control of machining tolerances. Axial compensation achieved by the use of floating bushings that allow high volumetric efficiency throughout the working pressure range. DU bearings ensure high pressure capability.
Pressure Limit	Inlet pressure: 7.38 in. Hg to 21.7 PSI. Pump Outlet: Continuous working pressure varies with displacement (See table below). Peak pressure pressures up to 4300 PSI.
Recommended Filtration	ISO 4406: < 2900 PSI: 20/19/16; > 2900 PSI: 19/18/15.
Recommended Fluids	Minimum Operating fluid viscosity: 66 SUS (with 80% reduction of working pressure and at minimum speed) to 3635 SUS (maximum starting viscosity). Normal operating range: 85 SUS to 297 SUS.
Speed Ratings	Continuous speed at working pressure varies with displacement (See table below).
Temperature Rating	With Buna-N seals (standard): -4°F to 185°F. With FPM seals (Viton): -4°F to 230°F.
