Vickers (a brand under Eaton Corporation) is a leading manufacturer of hydraulic components, and its piston pumps are widely used in pipeline forming equipment (such as pipe bending machines, pipe expanding machines, pipe flanging machines and pipe pressing machines) due to their high pressure resistance, stable output, precise flow control and strong adaptability. These piston pumps provide reliable high-pressure hydraulic power for the forming mechanisms of pipeline equipment, ensuring the accuracy and stability of pipeline bending, expanding and shaping, and adapting to the harsh working conditions of industrial pipeline processing workshops. The main applicable series and models are as follows:

1. PVH Series (High-Pressure Variable Displacement Piston Pumps)

The PVH series is a high-pressure variable displacement axial piston pump specially designed for industrial heavy-duty hydraulic systems, which is the core series of Vickers piston pumps for pipeline forming equipment. It adopts a pressure-compensated variable design, which can automatically adjust the displacement according to the pressure demand of pipeline forming, realizing energy saving and precise control. It has the advantages of high rated pressure, low noise and long service life, and is suitable for the main hydraulic circuits of medium and large-scale pipeline forming equipment that require high pressure and precise forming.

3. PVQ Series (Variable Displacement Piston Pumps for Precision Control)

The PVQ series is a variable displacement piston pump with precise flow control, which is specially suitable for pipeline forming equipment that requires high forming accuracy (such as precision pipe bending, pipe end forming). It adopts a servo-controlled variable mechanism, which can realize precise adjustment of flow and pressure, ensuring the consistency of pipeline forming dimensions. It has the advantages of low noise, high efficiency and strong anti-interference ability, and is widely used in precision pipeline processing equipment.

• PVQ32-A2R-SE1S-20-C14-12: Displacement 32 mL/r, rated pressure 280 bar (4060 psi), large flow and high precision, suitable for precision large-diameter pipeline forming equipment

4. PV Series (Fixed Displacement Piston Pumps)

The PV series is a fixed displacement axial piston pump with simple structure, high reliability and low cost, which is suitable for the auxiliary hydraulic circuits of pipeline forming equipment, such as the lubrication of forming mechanisms, the control of clamping devices and the auxiliary feeding mechanism. It can also be used as a main pump for small pipeline forming equipment with stable working conditions and low pressure requirements.

Core Models:

• PV2R1-10-F-R: Displacement 10 mL/r, rated pressure 160 bar (2320 psi), suitable for auxiliary hydraulic circuits of small pipe bending machines
• PV2R1-23-F-R: Displacement 23 mL/r, rated pressure 160 bar (2320 psi), suitable for auxiliary clamping and feeding mechanisms of medium-sized pipeline forming equipment
• PV2R2-41-F-R: Displacement 41 mL/r, rated pressure 160 bar (2320 psi), suitable for main hydraulic circuits of small pipe pressing machines and simple pipe forming equipment

Note: The specific models and parameters of Vickers piston pumps for pipeline forming equipment may vary according to the type of pipeline forming equipment, pipeline diameter, forming process (such as cold forming or hot forming) and working pressure requirements. For accurate model selection, it is recommended to refer to Eaton Vickers official technical manual or consult authorized suppliers. In addition, these piston pumps are compatible with most industrial hydraulic oils, and their working temperature range is -10℃ to +80℃, which can adapt to most industrial pipeline processing scenarios, including the working environment of vacuum-assisted forming processes with specific hydraulic viscosity requirements.
