What operation advantages can the intra-vane hydraulically balanced structure bring?

Symmetric stator counteracts radial hydraulic force to reduce bearing wear, realize low vibration and low noise operation, maintain stable volumetric efficiency under long-term continuous operation and extend service life.

Is it necessary to remove the whole pump from equipment for maintenance of thru-drive pump?

Complete pump disassembly is not required. The internal insert cartridge can be pulled out and replaced separately for simple maintenance, greatly cutting production line downtime.

Can fire-resistant hydraulic fluid be used for this thru-drive pump?

Yes, besides conventional 32# and 46# anti-wear hydraulic oil, it is also compatible with water glycol and phosphate ester fire-resistant fluid to meet the usage demands of explosion-proof and high-temperature special working conditions.

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 structure does the letter T in model suffix VT represent?

Letter T stands for rear thru-drive structure. The pump rear end is equipped with a through drive shaft, which can directly connect other hydraulic pumps to form multi-pump systems.

Q:What are the differences in displacement and applicable equipment among 25VT, 35VT and 45VT thru-drive pumps?

25VT small displacement fits mini machine tools and compact hydraulic power units. 35VT medium displacement is suitable for medium-small injection molding and die casting equipment. 45VT large displacement matches large plastic machines and heavy multi-circuit hydraulic stations.

Q:What types of hydraulic pumps can be connected at the rear end of thru-drive pumps?

It can connect VT series thru-drive pumps, ordinary V series single vane pumps, gear pumps and variable piston pumps, freely matching high-low pressure and fixed-variable displacement combinations.

Q:What advantages does the thru-drive tandem scheme have compared with factory integrated tandem pumps?

The thru-drive solution allows free matching of pump bodies with different displacements and types on demand. Additional pumps can be added to expand oil circuits in the later stage without replacing the whole pump, bringing higher flexibility for equipment transformation.

Q:What is the maximum continuous working pressure of this thru-drive vane pump?

The continuous working pressure of standard model is 172bar, and the short-term peak pressure can reach 190bar, suitable for medium and high pressure industrial hydraulic working conditions.
