4 Whisper™ VPV Vane Pump Catalog | Introduction
Bosch Rexroth Corp., 9 535 233 724, Edition: 01-2014
Introduction
This catalog provides details on the Rexroth VPV series vari-
able vane pump, including performance, dimensional, and
technical specifications. Please consult the factory if further
details are required.
The pumps are designed to meet the requirements of the
machine tool, general machinery, and other markets where
low noise, high performance and competitive pricing are
needed.
The design of the VPV series of vane pumps utilizes 30 years
of field and manufacturing experience from the current
Rexroth vane pump line. State-of-the-art technologies and
materials were utilized while retaining the superior features
of the existing designs. Additional goals were to create a
pump with the international market in mind and to incorpo-
rate the extremely high quality standards the Rexroth name
has come to exemplify.
Keeping in mind market expectations, Bosch Rexroth Corpo-
ration developed a pump with the following improvements
and features:
▶ High reliability with fewer parts.
▶ Significant advances in noise reduction.
▶ High volumetric and overall efficiency.
▶ Excellent durability.
▶ Modern appearance.
▶ Improved ring and vane wear technology.
▶ Very good response and recovery times.
▶ Generally reduced envelope size.
▶ Redesigned controls with shock clipper.
▶ Conforms to the latest SAE, ISO, NFPA, and ANSI stan-
dards.
▶ Combination capability - full horsepower may be trans-
ferred to pump 2. Combinations of construction of mul-
tiple pumps may be required to be de-rated.
Benefits
▶ LOW COST - Competitively priced with other manufactur-
ers of vane pumps and economy axial piston pumps.
▶ EXCEPTIONALLY QUIET - Helps machinery builders meet
government and purchased sound level requirements.
▶ CONTINUOUS DUTY RATING - @ 3,000 PSI - High perfor-
mance and long life design for 10,000 plus hours.
▶ HIGHLY EFFICIENT FAST RESPONSE & RECOVERY - Excep-
tional reaction time for critical system demands.
▶ PRESSURE COMPENSATED - Controls pump delivery to
circuit demand thereby conserving energy.
▶ HIGH STRENGTH - Computer optimized casting design.
▶ HYDRODYNAMIC JOURNAL BEARINGS - Provides long life
and quiet operation.
▶ NO PREFILL REQUIREMENTS - Pump case prefill not
required for initial start-ups.
▶ REPAIRABLE - Repair kits and parts available from local
distribution centers or the factory.
▶ CONTROL OPTIONS - Single stage; two-stage, remote
control; solenoid multi-pressure, and load sensing.
▶ SHOCK CLIPPER - Reduces shock pressure by up to 50%
increasing system component life and system stability.
Must be plumbed on VPV 16, 25, & 32. The shock clipper
is integrated into VPV 45, 63, 80, 100, 130, & 164 and
drains to the case drain. See page 86.
