VICKERS PVM Piston Pump PVM045SER07CS2C230200001AB-BD00: Detailed Overview

This pump belongs to the PVM series under Danfoss Power Systems' VICKERS brand, featuring an open-circuit axial piston swashplate design with variable displacement capabilities. Below is a detailed breakdown:

I. Brand and Series Characteristics

1. Brand and Series

• Part of the VICKERS PVM series by Danfoss Power Systems, this is an open-circuit axial piston pump with a swashplate mechanism for variable displacement.

2. Key Advantages

• High-Pressure Performance: Continuous operating pressure up to 280 bar (4,060 psi), peak pressure of 315 bar (4,568 psi), suitable for demanding applications.

• Energy Efficiency: Stepless flow adjustment via swashplate angle modulation reduces high-pressure throttling losses, achieving ~95% volumetric efficiency.

• Low Noise & Durability: Optimized rotating components and a bimetallic port plate design ensure noise levels ≤70 dB(A), with heavy-duty bearings rated for 30,000 hours (at 65% rated pressure).

• Compact Structure: Saddle-shaped yoke and steel-backed polymer bearings minimize pump size, enabling installation in tight spaces.

II. Model Breakdown (PVM045SER07CS2C230200001AB-BD00)

1. Basic Parameters

• Displacement: 45 cm³/rev (PVM045), ideal for medium-flow applications.

• Control Type: Pressure-compensated control (Code A), automatically adjusting flow based on load pressure to maintain system stability.

• Design Optimization: Bimetallic port plate improves filling characteristics, reduces fluid noise, and extends service life.

2. Structural and Material Features

• Bearing System: Steel-backed polymer bearings with a rigid yoke reduce deflection and ensure uniform load distribution, enhancing reliability.

• Sealing and Ports: Standard inlet/outlet pressure gauge ports for system monitoring; adjustable maximum displacement stop for simplified flow calibration.

3. Performance Specifications

• Rated Pressure: 28 MPa (280 bar), maximum pressure of 31.5 MPa (315 bar).

• Speed Range: Compatible with high-speed servo motors, rated at 3,800 rpm (refer to technical manual for PVM045-specific data).

• Noise Level: ≤70 dB(A) (based on PVM074 model; similar expected for PVM045).

III. Typical Applications

1. Industrial Hydraulic Systems

• Injection Molding Machines: Provides stable high-pressure oil supply for rapid injection and holding pressure cycles.

• Machine Tools: Drives spindles and worktables for precise motion control.

• Die-Casting Machines: Withstands high-temperature/pressure conditions to ensure consistent metal filling.

2. Construction Machinery

• Hydraulic Circuits: Powers excavators, cranes, and other equipment for efficient power transmission.

• Industrial Presses: Delivers sustained pressure for metal forming and compression processes.

3. Other Fields

• Hydraulic Power Units: Serves as a core component in distributed hydraulic systems.

• Automation Equipment: Adapts to robots and assembly lines requiring precise flow control.

IV. Technical Highlights and Benefits

1. Pressure-Compensated Control

• Automatically adjusts pump displacement based on load pressure, eliminating high-pressure throttling losses and improving energy efficiency.

• Maintains stable system pressure, reducing equipment wear from pressure fluctuations.

2. Low-Maintenance Design

• Open-circuit structure with fewer wear parts, lowering maintenance costs.

• Standardized ports for quick inspection and component replacement.

3. Environmental Adaptability

• Optimized fluid noise design for noise-sensitive indoor environments.

• Heavy-duty bearings and rigid drive shafts withstand harsh conditions and frequent start-stop cycles.
