Design Innovations
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 Life: Hydraulically unloaded shaft design ensures extended bearing service life
- Low Wear Characteristics: Hydraulically unloaded vanes experience minimal wear during operation
- Low Operating Noise: Optimized design results in quiet operation for noise-sensitive environments
- High Efficiency: Axial gap compensation and optimized flow paths ensure excellent volumetric and mechanical efficiency
- Flexible Configuration: Optional positioning of pressure connections, rotation options, and drive shaft types
Applications
- Mobile machinery applications
- Industrial hydraulic systems
- Presses and injection molding machines
- Open circuit hydraulic systems
- Systems requiring compact, high-performance pumps
Installation and Operation
Mounting Requirements
- 2-hole mounting flange 101-2 according to ISO 3019-1
- SAE B standard mounting
