Jiangsu Hongda High Pressure Oil Pump Manufacturing Co., Ltd.

Hongda also lists other CY14-1B control variants, HY pumps, hydraulic motors and complete hydraulic-system equipment. A family appearing in the catalogue does not make these variants interchangeable. Include the full suffix and control requirement in a replacement enquiry.

The MCY table’s size 25 row lists 25 mL/rev, 31.5 MPa nominal pressure, and theoretical flow of 25 L/min at 1,000 r/min or 37.5 L/min at 1,500 r/min. The photographed 25MCY illustrates that fixed-displacement direction. Ask for delivery and efficiency at the actual pressure, oil viscosity and temperature rather than treating theoretical flow as a test guarantee.

The SCY page identifies manual displacement adjustment and explains size 63 at 1,000 r/min as a nominal 63 L/min direction. At full nominal displacement, 63 mL/rev at 1,500 r/min corresponds to 94.5 L/min theoretical flow. A reduced manual setting changes delivery; request the offered control’s adjustment range, setting method and installation access.

The supplier gives a drive-power estimate using flow, pressure and an assumed overall efficiency. Size the motor for the real load cycle, losses, starting method and system controls. A single catalogue efficiency assumption is not a guaranteed efficiency map or a reason to omit the circuit’s pressure protection.

The A2F page describes a fixed-displacement bent-axis unit for pump or motor service. Identify which duty is required: a pump’s delivered flow and a motor’s torque/speed requirements are different selection inputs. Confirm the port functions, rotation, shaft loading and approved mounting arrangement for that duty.

For size 63, the published table lists 63 mL/rev and an approximate unit weight of 33 kg. Its closed-circuit maximum-speed row is 4,000 r/min. The open-circuit entries are 2,550, 2,700 and 3,300 r/min at respectively 0.09, 0.10 and 0.15 MPa absolute inlet pressure. These are distinct catalogue conditions, not a universal permissible speed or a combined maximum duty.

Give the supplier the minimum absolute pressure available at the inlet, including reservoir level and line losses, with the oil viscosity and temperature. Request confirmation of speed, pressure duration and charge/inlet requirements for the selected unit and circuit. A positive gauge reading or an oil-tank elevation alone does not establish every table condition.

For the reviewed CY14-1B guidance, Hongda specifies N32–46 hydraulic oil, normal oil temperature of 10–65°C and a 15–20 µm return-filter direction. Obtain the offered pump’s current oil, viscosity, cleanliness and temperature requirements and agree how the system will achieve them. Do not apply these CY instructions automatically to A2F or other hydraulic units.

The CY instructions call for a separate case-drain connection directly to the reservoir and warn against a fine filter that increases case pressure. They also warn against excessive inlet resistance. Supply inlet and drain sizes, lengths, fittings, reservoir levels and the intended filtration scheme; request the selected unit’s allowable inlet and case pressures instead of improvising a restrictive drain connection.

Before initial start, the CY guidance requires filling the pump casing with clean working oil and checking rotation and alignment, then starting with the system unloaded. Agree a commissioning procedure for the actual unit, circuit and control arrangement. A family description of self-priming does not permit starting an empty case or ignoring the inlet conditions.

The CY instructions recommend a supported aligned coupling and warn against imposing unsupported belt or gear loads on its shaft. The A2F description mentions radial-load capability, but gives no blanket approval for an arbitrary external load. Submit the actual drive arrangement for the exact unit.

1. Record the complete existing unit

   Photograph the nameplate, full model/control suffix, rotation marking, mounting and all connections. State whether it is a pump or motor and describe the machine cycle.

2. Compare the hydraulic duty

   Provide required flow or motor torque/speed, drive speed, working/peak pressure and duration, oil and temperature, circuit drawing and inlet conditions.

3. Compare the mechanical interfaces

   Request dimensioned shaft/key/spline, flange, bolt pattern and port drawings. Confirm alignment and permitted radial/axial loading; visual similarity is insufficient.

4. Compare control and drain connections

   Define manual or automatic control, required range and accessibility. Match case-drain and auxiliary connections to the circuit and permitted pressures.

5. Agree the acceptance and service package

   Request the offered unit’s test record and applicable instructions, replacement-part identification and agreed inspection criteria. State what is included in a pump-only or complete-system order.

The official profile identifies 江苏宏达高压油泵制造有限公司 in Qidong and traces the business to the early 1990s. It describes casting, machining and hydraulic-system production alongside pumps, motors, valves and cylinders. That history is not used as the present legal entity’s registration date or as proof of current output capacity.

The PTC ASIA organiser’s 2020 exhibitor list independently names the same legal company and lists stand D3-2. This historical identity cross-check does not establish current exhibition participation, business status or certification. The official site also contains differing contact-address blocks and an old ISO9001-2000 statement; confirm the contracting entity, current dispatch location and any required valid certificates in the quotation.

For a complete hydraulic system, request the circuit diagram, component schedule, drive/control interfaces and acceptance plan. For a replacement pump, ask for the selected unit’s inspection record and matching drawings. A company test-equipment statement or historical listing cannot substitute for order-specific evidence.

Reviewed on 8 October 2026 from the official company profile, MCY/SCY/A2F pages and original parameter-table images, with the PTC ASIA organiser’s historical 2020 exhibitor list used only to cross-check identity. Photographs illustrate published families. Confirm the supplier’s current offered configuration and operating limits for the actual machine.
