VQH series vane pumps
Economical VQH series pumps are higher-pressure, higher-performance versions of VQ series pumps. They have the same envelope sizes as VQ pumps but feature strong ductile-iron housings. Available with displacements up to 193 cm3 [11.80 in3] and pressure ratings up to 241 bar [3,500 psi], these fixed-displacement single- and double-vane pumps provide high power density, efficiency, and serviceability.
Features and benefits
- Strong ductile iron housing
- Improved rotor design to reduce leakage and enhance rotor rigidity
- High-pressure and performance capabilities
- 10-vane systems
- Many available bearing and valve options
Applications
- Hydraulic power units
- Industrial presses
- Blow/injection molding
