FAQ
▔▔
Q1: What parameters should be confirmed prior to purchasing?
A: Confirm displacement size, max continuous operating pressure, shaft type (keyed or splined), rotation direction, mounting style, and specific control valve configuration.
Q2: What cleanliness level and filtration level are required for PVQ pumps?
A: System fluid must be maintained at ISO 4406 cleanliness level 18/15/13 or better. We recommend using a return-line filter with a nominal rating of 10 microns to prevent internal component wear.
Q3: What type of hydraulic oil is recommended for optimal performance?
A: Use high-quality mineral-based hydraulic oils (HLP or HVLP) conforming to ISO VG 32, 46, or 68 depending on ambient working temperature. Ensure fluid viscosity stays between 16 and 40 cSt during operation.

FAQ
▔▔Q1: What makes the Eaton Vickers PVQ pump much quieter than standard axial piston pumps?
Answer: The PVQ series features a patented internal valve timing design that optimizes fluid commutation as pistons transition between suction and discharge zones. This drastically attenuates pressure ripple within the outlet port and dampens structure-borne vibration, resulting in operational noise levels that match or sit below the noise level of the electric driving motor.
Q2: Can the PVQ pump operate on fire-resistant or synthetic hydraulic fluids?
Answer: Yes. In addition to conventional mineral-based (petroleum) hydraulic oils, PVQ pumps are fully qualified for use with water-glycol fluids, polyol esters, synthetic hydrocarbons, and phosphate ester fluids. When using synthetic or fire-resistant fluids, ensure the correct seal material option (e.g., Fluorocarbon / Viton seals marked as "F" in the model code) is specified.
