Concentric Hydraulic Pumps

Hydraulic Pumps

Hydraulic pumps are designed to generate fluid pressures for more easily moving heavier loads and providing greater force in a variety of applications. These hard-working tools are used in mobile equipment, construction and agricultural equipment, machine tools, material handling, aerial lifts and mining equipment, refuse haulers, compaction and baling equipment and more.

The main types include gear hydraulic pumps, vane hydraulic pumps and piston hydraulic pumps. Gear hydraulic pumps (external, internal and axial flow) are affordable and provide a constant flow rate but are low volumetric efficiency. Vane hydraulic pumps offer improved volumetric efficiency and less noise. Piston hydraulic pumps (inline axial, radial and bent axis) are reliable options with high pressure and high volumetric efficiency. When shopping for a hydraulic pump, you will encounter different styles, including PTO, high-pressure, air/hydraulic, 12 Volt and even hand pumps. Some styles are available in fixed displacement or variable displacement configurations. Fixed displacement models move the same amount of fluid every cycle. Variable displacement units can change flow rate or outlet pressure for the situation.

To help further narrow down the possibilities, focus on a few of the key features, including PSI, RPM, max. flow rate and shaft type (splined, straight key and extended). Also consider the viscosity and type of the fluid being pumped, operating torque, temperature, speed and displacement. Northern Tool + Equipment carries a variety of hydraulic pump types with PSI ratings from 1,000 to 10,000 PSI and max. flow rates up to 56 GPM.
