The new VSQ Vane pump is built to combine the best features of Vane pumps with 0 RPM low speed capable architecture to support efficiency and energy savings. Combined with high speed and high operating pressure features, this pump is an optimal choice over internal gear and piston pumps for industrial applications. Eaton’s VSQ pumps provide continuous pressure ratings up to 280 bar (4060 psi) for the 25 frame size and displacements up to 180 cm3/r (10.98 in3/r) in the double pump configuration. In addition, further reductions in noise levels on an already quiet design offers real possibilities...

Pump characteristics. Rated pressure Pumps should not be operated at or near rated pressures at idle speeds for extended periods. Localized overheating and damage can result. Never assume pumps in a double, triple or thru-drive pump assembly can be simultaneously loaded to rated pressure. Shaft loading must be checked for excessive torque. Never load or unload a VSQ pump at rates greater than 10,342 bar/sec (150,000 psig/sec), because pump instability could occur. If unloading pump at rates over 5,171 bar/sec (75,000 psig/ sec), make sure inlet pressure does not fall below 0.83 bar (12 psi) absolute...
