Key Technical Specifications
General Series Features
Maximum Operating Pressure: 210 bar
Displacement Range: 18 to 193 cm³
Maximum Flow: Up to 285 l/min
Component Series: 1X
Frame Sizes: 1, 2, 4, 5
Seal Material: NBR (Butadiene Rubber)
Hydraulic Fluid: HLP

The PVV series incorporates several advanced design features:Hydraulic Unloading Technology
Double-eccentric stator ring design creates two pressure chambers opposite two suction chambers
Hydraulically unloaded shaft transmits only torque, extending bearing life
Partially unloaded vanes reduce wear during suction passage
Exchangeable Pump Cartridges
Pump insert (rotor, vane, stator ring, control plates) can be removed without disassembling the housing
Cover removal allows quick access for maintenance and repair
Significantly reduces downtime and maintenance costs
Double Pump Configuration
Extremely compact design with two pump installation kits on one joint shaft
Single suction port in central housing
Separate pressure ports for each pump
Larger pump installation kit always positioned on flange housing side
Performance Advantages
Long Bearing LifeThe hydraulically unloaded shaft design ensures extended bearing service life by transmitting only torque, not radial loads.Low Wear CharacteristicsHydraulically unloaded vanes experience minimal wear during operation, contributing to long-term reliability.Low Operating NoiseOptimized design results in quiet operation, making these pumps suitable for noise-sensitive environments.High EfficiencyAxial gap compensation and optimized flow paths ensure excellent volumetric and mechanical efficiency.Flexible Configuration
Optional positioning of pressure connections
Clockwise or counterclockwise rotation options
Cylindrical or splined drive shaft options
