Whisper™ Pumps VPV Vane Pumps
Introduction
This catalog provides details on the Rexroth VPV series variable 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 incorporate the extremely high quality standards the Rexroth name has come to exemplify. Keeping in mind market expectations, Bosch Rexroth Corporation 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 standards.
▶ Combination capability - full horsepower may be transferred to pump 2. Combinations of construction of multiple pumps may be required to be de-rated.
Benefits
▶ LOW COST - Competitively priced with other manufacturers 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 performance and long life design for 10,000 plus hours.
▶ HIGHLY EFFICIENT FAST RESPONSE & RECOVERY - Exceptional 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.
