Hagglunds Denison Announces Improvements In Hydraulic Pumps

Hagglunds Denison recently reported design improvements in the firm's World Cup line of axial piston hydraulic pumps provide increased reliability and longer life under severe operating conditions.

The pumps, designated "B" mod, are used in a variety of marine applications.

Three different series of pumps are offered. Series 6, 7 and 8 units have displacements of 6.0,7.25, and 8.0 inches 3/rev. respectively. Continuous pressure rating is 5,000 psi for the smaller displacement pumps and3,500psifortheSeries8. Maximum speed is 3,000 rpm for the Series 6 and 7 and 1,800 rpm for the Series 8.

The standard control for the World Cup pumps is a pressure compensator located in the cover assembly. Minimum compensating pressure is approximately 180 psi. Five control options include an electrohydraulic stroker, hydraulic stroker, rotary servo, load-sensing compensator, and a torque limiter.
