Hydraulic Pump Manufacturers

Zhejiang Vermillion Import and Export Co., Ltd. is a hydraulic machinery manufacturer based in Jiaxing, Zhejiang, China. We design, produce and supply hydraulic pumps that act as the power unit for shop presses, porta power sets, pipe benders, cylinders and other workshop and garage equipment. Our range spans rated capacities from 0.5 t to 100 t, organised into two main families: manual hand pumps and air-driven hydraulic pumps.

Every pump we ship is built around a defined working point — the force, stroke, oil volume and cycle pattern the tool has to deliver. That is the basis on which we select a model, set the relief, match the port and coupling, and prepare the quotation.

Our Hydraulic Pump Range

The catalogue below is the current production range. Manual models cover intermittent pressing and force application; air-driven models cover repeated cycles where shop air is available and operator effort should stay low.

Manual Hand Pumps: Single-Stage and Dual-Stage

Manual pumps remain the most widely used power source for workshop pressing because they need no electricity and no compressed air. The OY1200, OY1201, OY1203 and OY1203A share a long-ram format with a 630–1120 mm height range on the 3 t and 8 t models, which suits bench presses, frame straightening and field service work.

The OY1202 uses a two-stage circuit. The first stage moves a high oil flow to bring the ram or saddle up to the load quickly; once the load is engaged, the pump shifts to the high-pressure stage. In practice this cuts the number of idle strokes before contact, which matters on presses used many times per shift.

• Single-stage (OY1201): direct, predictable pressure build-up per stroke, simple to service in the field.
• Dual-stage (OY1202): faster approach to the workpiece, same physical envelope and weight class as the single-stage 8 t unit.
• Foot-operated (OY1001): 790 mL reservoir, useful where the operator must hold the workpiece during pumping.

Air-Driven Pumps and Reservoir Selection

Air-driven models convert workshop air into hydraulic pressure and are chosen when cycle counts are high or when the operator should not be pumping by hand. Reservoir volume is the main differentiator across the OY1000 series, and it drives how much cylinder stroke can be supplied before the oil returns.

• 690 mL (OY1003): compact body for confined mounting positions.
• 1300 mL (OY1002): general-purpose pneumatic unit for standard cylinder sizes.
• 2300 mL (OY1004): high-flow circuit for faster advance on longer strokes.
• 1.6 L aluminium (OY1005): lower reservoir weight where the pump is carried or mounted on a moving frame.
• 2.3 L PE (OY1006): medium-capacity unit for routine garage duty.
• 4.5 L steel (OY1007): largest oil volume, for multi-cylinder or long-stroke circuits.

Where Our Pumps Fit Across the Tool Range

Hydraulic pumps are supplied both as standalone service items and as the power unit inside our finished equipment. The same pump family therefore appears across several tool categories, and we match the pump to the tool rather than treating it as a separate purchase.

Finished equipment that uses these pumps includes the Hydraulic Shop Press, the Porta Power Jack and the Pipe Bender. As a Hydraulic Pump manufacturer, we supply the pump on its own for replacement and OEM programmes as well as installed in the complete tool.

Critical Specifications at the Working Point

Pump selection is settled by a small number of variables. We confirm each of them against the host tool before quoting, because a pump that is correct on capacity alone can still be wrong on stroke or oil volume.

• Rated capacity and relief setting: the force class the pump must support, and the pressure at which the relief protects the circuit.
• Usable oil volume: must cover the cylinder or ram displacement plus a working margin in the reservoir.
• Height and stroke range: 630–1120 mm on the long-ram manual models, which sets how the pump sits in the press frame.
• Drive method: hand, foot or air, matched to cycle frequency and available services.
• Port thread and coupling: the interface to the hose, cylinder or manifold.
• Reservoir material: steel, aluminium or PE, chosen for weight, environment and service life.

Materials, Seals and Reservoir Construction

Reservoir construction is one of the clearest ways to position a pump in a market. Aluminium reduces carried weight, PE keeps cost and corrosion resistance in balance for general workshop use, and steel gives the largest oil volume and the most robust body for high-cycle duty.

Seal and bore quality determine whether a pump holds pressure over a long shift. We machine and assemble to the drawing set for each model, and the hydraulic circuit is filled and function-tested before packing so that the unit arrives ready for connection rather than requiring workshop bleeding.

Controls, Automation Integration and Installation

Manual and air-driven pumps are self-contained power units, so integration is mainly mechanical and pneumatic rather than electrical. Where a pump feeds a cylinder on a fixture or a semi-automatic station, we configure the control arrangement around the required line interface.

• Air supply: confirm working pressure and flow at the pump inlet; air-driven models need a stable, dry supply.
• Mounting: bracket or frame position, access to the release valve and clearance for the lever or foot pedal.
• Circuit connection: hose length, coupling type and routing between pump and actuator.
• Operator safety: guarding of the press or fixture, relief protection, and a clear release path before any load is applied.
• Commissioning: fill and bleed procedure, first-cycle pressure check and confirmation of the relief setting.

Quality Control and Acceptance

Our plant operates under an ISO 9001 quality management system, and core hydraulic products carry CE certification for European market sales. Inspection runs through production rather than only at the end, with full inspection applied to avoid defective units reaching the carton.

• Incoming check on bodies, rams, seals and couplings.
• In-process inspection at machining and assembly stages.
• Pressure and function test on the assembled pump, including relief behaviour.
• Leak check and cycle test before packing.
• Packing and carton verification against the order specification.

OEM/ODM Customization, Documentation and Spare Parts

We support OEM and ODM programmes for wholesalers, distributors and brand owners. Customization covers laser marking of the customer logo, colour box and carton artwork, and user manuals in multiple languages including English, Japanese, Spanish and French.

Our engineering team also adjusts pressure, dimensions, appearance and operating structure to suit regional standards and working habits. For exclusive products we handle prototype design, sample production, mass production and testing as a single sequence. Spare parts supply continues after delivery, supported by operation video material and technical guidance for after-sales teams.

A proposal is only as good as the working point behind it. The table below lists what we need from a project to select the pump, set the relief and quote accurately.

Frequently Asked Questions

Which hydraulic pump suits a shop press?

The manual long-ram models are the standard fit: OY1200 at 3 t, OY1201 single-stage at 8 t and OY1202 dual-stage at 8 t, with OY1203 and OY1203A at 12 t for heavier pressing. The 630–1120 mm height range on the 3 t and 8 t units matches common press frames. Where a press runs many cycles per shift, the dual-stage OY1202 reduces the number of strokes before the ram contacts the load.

When should I choose an air-driven pump instead of a manual one?

Air-driven pumps suit repeated cycles, longer strokes and situations where the operator needs both hands at the tool. Reservoir volume decides how much cylinder displacement can be supplied: 690 mL on the compact OY1003, 1300 mL on OY1002, 2300 mL on the high-flow OY1004, and 4.5 L on the steel-reservoir OY1007. A stable, dry air supply at the pump inlet is the main installation requirement.

How do I choose between aluminium, PE and steel reservoirs?

Aluminium (OY1005, 1.6 L) keeps carried weight down, which helps on portable sets and moving frames. PE (OY1006, 2.3 L) balances cost and corrosion resistance for general workshop duty. Steel (OY1007, 4.5 L) provides the largest oil volume and the most robust body where cycle counts are high or the pump stays mounted on a machine.

Can you supply pumps as spare parts rather than complete tools?

Yes. The pump range is offered as a separate item for replacement, service stock and OEM programmes, as well as installed in our shop presses, porta power sets and pipe benders. Spare parts supply continues after delivery so that distributors can support their own customers without holding large inventories.

What customization is available on hydraulic pumps?

We laser-mark customer logos and produce colour boxes, cartons and multi-language manuals. Our engineering team can adjust pressure, dimensions, appearance and operating structure for regional standards and working habits, and we handle prototype design through to mass production and testing for exclusive models. Trial quantities are accepted so a new model can be tested in the market before bulk ordering.

What quality documentation accompanies a pump order?

Our plant works to an ISO 9001 quality management system and core hydraulic products hold CE certification for European sales. Inspection covers incoming components, in-process machining and assembly, pressure and function testing of the assembled pump, and a leak and cycle check before packing. Documentation is prepared to match the destination market and the order specification.
