Can these vane pumps run continuously for long hours within rated pressure?

Stable continuous operation can be realized when working within rated pressure range.

How to deal with abnormal noise generated during pump operation?

Adopt clean hydraulic oil, ensure sufficient oil suction pressure and check installation coaxiality.

What damage will be caused by severely contaminated hydraulic oil?

Impurities in oil will accelerate wear of vanes and cam ring and result in pressure drop and flow fluctuation.

AI-Powered supplier vetting

SummaryChangzhou Bejery Machinery Co., Ltd. is a manufacturing factory and limited company offering pumps and relay modules, with a registered scope covering mining machinery, electrical equipment, and refining and chemical production equipment. It reports broad customization services and new products during the past year, but does not provide ODM services or OEM services for popular brands. Export sales account for 90%, although the supplier reportedly began exporting only one year ago. The supplier has no stock service, overseas warehouse, overseas showroom, overseas agents or branches, and has not participated in offline trade shows. Its audit information identifies TÜV Rheinland, but the stated audit result is 0 and no certification details are provided. Financial records are indicated for 2022–2024, but no assessable financial performance data is supplied. Supplier-service assessment procedures are undocumented, while three qualified suppliers and some approved supplier names are reported.

Supplier typeThe supplier is identified as a factory located in Changzhou, Wujin District, and as a limited company. Its stated business scope includes manufacturing and sales of mining machinery, electrical equipment, and specialized refining and chemical production equipment, while its offered products are pumps and relay modules.

After-Sales capabilityThe supplier reports no in-stock service, overseas warehouse, overseas showroom, overseas agent or branch, and no overseas service countries. It accepts multiple payment terms and provides stated lead times, but its service-capability assessment has no written procedures or followed records, limiting evidence of structured after-sales support.

R&D capabilityThe supplier reports that it had new products during the past year and offers customization from samples, designs, full customization, flexible customization, and minor customization. Conversely, it has no available SDK and does not provide ODM services, so the evidence supports product-development activity but not broader platform or ODM capability.

Production capacityThe supplier identifies itself as a manufacturing factory with a machinery-related business scope, offers pumps and relay modules, and reports an average off-season lead time within 15 workdays and peak-season lead time of one month or within 15 workdays. However, its valid manufacturing contract status is unknown and it has no inventory capability, so production scale and contractual manufacturing readiness remain unverified.

Customization capabilityBoth customization records list customization from samples, full customization, customization from designs, flexible customization, and minor customization. This consistent evidence explicitly indicates broad customization coverage.

Product Q&A

Q:What is the main difference among VQ SVQ and DVQ series?

SVQ applies to low-pressure conditions, VQ is standard medium-pressure model, and DVQ with reinforced structure is suitable for higher pressure working environment.

Q:Are single pump and double pump both available for these three series?

All three series support single pump and double pump configurations for different circuit requirements.

Q:Can DVQ double pump supply oil for two separate hydraulic circuits?

Two pump cartridges work independently and can output oil for two different hydraulic circuits respectively.

Q:What hydraulic oil viscosity is recommended for VQ SVQ DVQ vane pumps?

Hydraulic oil with viscosity ranging from 32 cSt to 68 cSt is recommended under normal working temperature.

Q:Do standard VQ SVQ DVQ pumps support bidirectional rotation?

Standard products adopt single rotation direction, customized rotation can be provided upon request.
