Rotary vane pump CONTINENTAL HYDRAULICS

The variable volume and pressure compensated design simplifies circuit design, reduces heat and noise, and can lower horsepower requirements. These rugged PVR vane pumps feature compact design and excellent horsepower to weight ratios, and are known for being the medium pressure workhorse in the industry. PVR pumps maintain constant pressure while matching system flow demands.

A direct spring operated compensator provides fast response for varying system demands and eliminates contamination prone hydraulic assisted compensator valves and pistons. The patented "Walking Ring" design is a unique indexing pressure ring design that rotates slightly with every change in output. Wear is distributed evenly around the inside surface of the ring circumference, which helps to extend pump life.

Hydrodynamic journal bearings eliminate shaft to bearing contact, and since there are no moving parts with this bearing design, pump life is not determined by a B-10 rating. Balanced vane tip loading acts throughout the entire pumping cycle to extend ring and vane life. The one piece forged rotor shaft can absorb system loads with minimal deflection.

To simplify maintenance, the patented pressure balanced thrust plate eliminates the need for shims and spacer units, and yields pump efficiencies up to 90%. Computer designed porting reduces noise at all pressure and flow levels with noise levels as low as 68 dBa [NFPA T3.9 12M-1970 (R1981) Tested]. This can help eliminate the costs for special noise abatement enclosures.
