HPV Duraforce Closed Loop Variable Displacement Pump

DuraForce HPV Series Pumps offer 500 bar peak pressure with high precision and load independent control needed for inching large machines forward in tight spaces or powering drill heads to extreme depths.

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.
