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
