HPR Duraforce Open Loop Variable Displacement Pump

Combining 500 bar peak pressure, an innovative noise reduction solution and a broad controls selection, DuraForce HPR Series Pumps bring impressive product strengths to a wide variety of applications.

Extreme duty cycles. High pressure applications. Heavy-duty equipment. Sometimes the specs call for heavy lifting, and that’s when you need maximum muscle.

Builders of some of the world’s most powerful equipment rely on DuraForce Pumps for the muscle and precision they need for demanding applications. Other equipment builders choose DuraForce products for a simpler reason: the peace of mind that comes through reliable operation and extended machine life.

From construction, mining and material handling to agriculture, oil and gas drilling and process industries, the DuraForce name has come to mean best-in-class performance and rock-solid dependability.
