H Series High Pressure Piston Pumps
High pressure pumps operate with extended life at pressures to 10 000 psi (700 bar). These fixed displacement piston pumps include models in these Series:
The pumps provide a range of output flows from 1.5 to 17.2 gpm (5,7 to 65,1 L/min) at 1800 rpm.
High Efficiency Design
The checkball pump design uses piston check valves to direct flow from the pump inlet to the outlet. The positive-seating check valves provide high volumetric efficiency, especially at higher pressures.
The outlet check valves provide a relatively large flushing path for any system contamination. This makes the pumps ideal for systems where the fluid cannot be totally cleaned by filtration, or where it is just not economical.
High pressure pumps operate at pressures up to 20,000 PSI (1380 bar).
The checkball pump design is ideal for hydraulic systems with demanding conditions including:
PF500 Series Compact 10 000 psi (700 bar) Pumps
High pressure capability and low input power requirements, as low as 1 HP at 10 000 psi (0.7 kW at 700 bar), make PF500 Series pumps ideal for applications with limited power supply.
The pumps can also be used on portable power packs for high-torque wrenches, other service tools and similar high pressure applications.
Compact, High-Pressure Piston Pumps
PF500 Series fixed displacement pumps operate at pressures to 10 000 psi (700 bar) continuous and 15 000 psi (1040 bar) maximum intermittent.
Low Input Power
Input power requirements, as low as 1 HP at 10 000 psi (0.7 kW at 700 bar), make these pumps ideal for use in remote locations with limited power supply.
Flows from 0.22 to 0.70 U.S. gpm (0,83 to 2,65 L/min) at 1800 rpm are available in four models.
Multiple Output Pumps
Split-Flow® models provide multiple outputs for synchronized actuator movement or multiple function circuits.
These multiple outlet pumps can efficiently supply flow in a circuit with changing flow and pressure requirements. This makes them ideal for Hi-Lo circuits on clamping, pressing and high-pressure tool applications.
Bi-Directional Shaft Rotation
With these fixed displacement pumps the direction of output flow is constant, regardless of drive shaft rotation. Bi-directional shaft rotation can be an advantage when using double-ended electric motors, requiring only one model to be specified.
