NVICKS VQ Series Hydraulic Vane Pump — 20VQ, 25VQ | RFQ Sourcing Details

The NVICKS VQ series is a single-acting hydraulic vane pump range comprising the 20VQ, 25VQ, 35VQ and 45VQ models. It is presented for industrial hydraulic equipment, including plastic injection, shoe, machine-tool, die-casting and metallurgical machinery.

Supported configuration details The published selection table lists numerous flow codes across the four frame sizes. Corresponding geometric displacements extend from 7 mL/rev for the 20VQ-2 configuration to 237 mL/rev for the 45VQ-75 configuration.

Maximum listed operating pressure is 21 MPa for many configurations, while certain higher-flow options are listed at 14 MPa and the 45VQ-42 configuration is listed at 17.5 MPa. Maximum speed varies by configuration from 2,200 to 2,700 r/min, with a listed minimum speed of 600 r/min.

Available selection elements include straight-key, heavy-duty straight-key and spline shaft options, depending on series. Four outlet orientations are documented: opposite the inlet, 90 degrees counterclockwise from the inlet, inline with the inlet, or 90 degrees clockwise from the inlet.

Right-hand clockwise and left-hand counterclockwise rotation codes are also listed. The model coding information identifies options for petroleum oil, oil-emulsion fluid, water-glycol fluid and phosphate-ester fluid. The described hydraulic balancing structure is intended to reduce vane loading against the stator.

A twelve-vane arrangement is stated to reduce flow pulsation and system noise, with noise specified as below 70 dB. The cartridge is independent of the drive shaft, allowing cartridge servicing without removing the complete pump from its mounting. The listed construction specification is cast iron.

Quality and supply information The source states that every unit receives pre-shipment functional inspection and a tracking code. A one-year warranty after shipment is listed, together with technical support. OEM, ODM and several levels of customization are offered. The stated packing method is a wooden box.

Procurement questions to confirm Before ordering, confirm the exact VQ series, flow code and geometric displacement required. The buyer should also verify the permitted pressure and speed for that specific code rather than applying a series-level maximum to every configuration.

Confirm the working fluid, shaft type, mounting and port connection, outlet orientation, direction of rotation and required seal arrangement. Ask for a dimensional drawing and connection details for fit verification, because usable installation dimensions are not provided here.

Also confirm operating viscosity and temperature limits, inlet conditions, filtration requirements, expected noise-test conditions, and whether the requested model is a single pump or a double-pump assembly. Certification scope and documentation should be checked against the exact ordered configuration.

Finally, agree on inspection records, warranty procedure, customization scope, packaging, production schedule and shipment terms in the purchase documentation.
