Product details

The table separates a 970 r/min input-shaft selection from a 1,460 r/min input selection. Their listed pump speeds are 336 and 513 r/min respectively. Input speed must therefore not be copied into the pump-speed field when specifying or comparing the assembly.

For example, the 20 mm plunger row gives 318 bar rated pressure. At 970 r/min input and 336 r/min pump speed, theoretical flow is 11.91 L/min and the table’s effective-power value is 7.5 kW. At the higher listed speed, that row gives 18.18 L/min and 11.5 kW. These are table power values, not an independently established motor nameplate rating.

The main product page lists 3.8 L oil capacity, 0.1–0.2 MPa inlet pressure and 150 kg unit weight. The highest flow and highest pressure belong to different plunger diameters. Confirm liquid quality, selected plunger, continuous duty, drive power and pressure-control equipment as a complete system.

SELECTION NOTES

Specify the operating duty

State required flow and working pressure, liquid quality and temperature, inlet supply pressure, duty cycle and drive speed. Confirm plunger diameter, gear ratio, motor sizing and pressure-control package.

Published limits may describe different configurations within a series. Confirm that the required operating conditions are valid together.
