Can the angle of inlet and outlet ports of tandem pump be adjusted according to on-site pipelines?

Inlet and outlet ports support multi-angle rotation adjustment with standard SAE flanges to fit pipeline layout of various equipment.

What operation precautions should be taken for initial startup of V2010 V2020 tandem pumps?

Fill oil into pump cavity before startup, adopt jog mode to exhaust air, run under no load first then pressurize gradually. Long-time dry running and cavitation operation are forbidden.

What usually causes low pressure and insufficient flow of tandem pump hydraulic system?

Air leakage of suction pipeline, clogged filter, worn floating valve plate, worn vanes and internal leakage caused by failed internal seals will lead to insufficient pressure and flow.

Key features

Integrated tandem series structure enables one single motor to drive two independent hydraulic oil circuits, eliminating the need for two separate oil pumps and greatly reducing the floor space of hyd

Symmetric balanced stator structure counteracts radial hydraulic force to greatly reduce bearing wear and extend service life under long-term continuous equipment operation

Floating valve plate automatically compensates end face wear clearance to avoid stator scratch during cold and hot startup and maintain stable volumetric efficiency across full pressure range

Independent insert cartridge assembly allows on-site maintenance without complete pump disassembly. Damaged cartridges can be replaced separately to cut equipment downtime for maintenance

Inlet and outlet ports support multi-angle rotation adjustment with standard SAE mounting flanges, multiple shaft ends and rotation directions to fit pipeline layout of various equipment

The standard continuous working pressure reaches 17.2MPa with short-term peak pressure of 19.3MPa, suitable for medium and low pressure industrial hydraulic systems such as machine tools, plastic mach

Compatible with ISO VG32 and VG46 anti-wear hydraulic oil with strong fluid compatibility for conventional industrial hydraulic 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 are the core differences between V2010 and V2020 tandem pumps?

V2010 combines large V20 cartridge with small V10 pilot cartridge for main circuit and pilot control. V2020 consists of two V20 cartridges with equal displacement for two synchronous large-flow main oil circuits.

Q:Will the pressure and flow of two oil circuits of V2010 tandem pump interfere with each other?

The two oil circuits are independent with separate flow and pressure, which can match different load movement demands respectively.

Q:What is the maximum continuous working pressure of this tandem vane pump?

The continuous working pressure of standard model is 17.2MPa, and the short-term peak pressure can reach 19.3MPa.

Q:What operation advantages can balanced stator structure bring?

Symmetrically arranged inlet and outlet ports counteract radial hydraulic force to reduce bearing load, realize low vibration and low noise operation, and effectively extend pump service life.

Q:Is it necessary to remove the whole pump from equipment for maintenance of tandem pump?

Complete pump disassembly is not required. The internal insert cartridge can be pulled out and replaced separately for simple and convenient maintenance.
