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
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.
