PVM141ER10GS2C230000000AB Vickers Piston Pump 141cc 230bar

Product Overview

The PVM141ER10GS2C230000000AB is a Vickers (now Danfoss) PVM Series open-circuit swashplate-type axial piston variable displacement pump. The PVM Series is Vickers’ classic industrial product line, with displacements covering 18 to 141 cm³/rev—the PVM141 represents the largest displacement model in the series. This model delivers a maximum displacement of 141 cm³/rev.

This model features Pressure Compensator control, with C2 code indicating pressure and flow compensator with plugged orifice. The 230 denotes a pressure compensator setting of 230 bar. R indicates right-hand rotation (clockwise when viewed from the shaft end). 10 denotes the SAE straight keyed shaft specification. GS2 is the mounting flange and port configuration code.

As a direct OEM-equivalent replacement solution for the Vickers PVM Series, this product offers complete in-situ interchangeability, strictly adhering to Vickers’ original design specifications and mounting interface standards. Every unit undergoes 100% simulated duty-cycle testing, ensuring that key performance metrics—including volumetric efficiency, pressure-flow characteristics, and case drain flow at rated pressure and full displacement—meet or exceed original factory specifications.

Key Technical Advantages

1. Pressure Compensator Control for Stable and Reliable System Pressure
This model features Pressure Compensator control with a 230 bar setting. When system pressure reaches the set point, the pump automatically reduces displacement to only the small flow required to maintain pressure, significantly reducing overflow losses and system heat generation for energy-efficient operation.

2. 8,000-Hour Bearing Life for Long-Term Reliability
The PVM141 delivers 8,000 hours of bearing life at rated pressure. Heavy-duty bearings with a rigid drive shaft ensure long-term reliability under continuous high-load operating conditions.

3. Ultra-Low Pressure Ripple (≤ 4%) with 64 dB Low-Noise Operation
The PVM Series delivers extremely low pressure ripple of just 4%  with an operating noise level of just 64 dB. Combined with the PVM Series’ renowned 50% noise reduction characteristic, this significantly improves the operator’s working environment.

4. Saddle-Type Yoke with Steel-Backed Polymer Bearings for Extended Service Life
The PVM Series features a saddle-type yoke design with steel-backed polymer bearings. The rigid yoke reduces deflection and ensures even bearing load distribution, significantly extending service life.

5. Three-Piece Housing with Bimetallic Timing Plate – Leak-Free System Design
The PVM Series features a three-piece housing (flange, housing, and valve block) design that promotes a leak-free system. The adjustable maximum displacement stop and inlet/outlet pressure gauge ports are standard equipment.

Application Areas

• Metal Forming & Processing Equipment: Metal shears, tube forming and bending machines

• Injection Molding Machines: Replaces fixed-displacement pumps for variable flow control

• Mining Machinery: Hydraulic systems for mining equipment

• Metallurgical Equipment: Primary metals industry hydraulic systems

• Material Handling Equipment: Conveyor lines and material conveyors

• Oil & Gas Equipment: Hydraulic power units for oil and gas applications

• Specialized Applications: Flight simulators, entertainment rides

Expert Maintenance Tips

1. Model Confirmation & Pre-Installation Inspection: Prior to installation, confirm the complete model code as PVM141ER10GS2C230000000AB. This model features SAE C 4-bolt flange mounting (SAE J744-127-4) with an SAE straight keyed shaft. The pump weighs approximately 66 kg (145 lb) —ensure lifting equipment has adequate capacity. Manually rotate the shaft before installation to confirm smooth, obstruction-free rotation.

2. Fluid Cleanliness Control: Recommended filtration rating is ISO 18/13. Cold start temperature limit is 104 °C. Complete system flushing is mandatory before initial start-up.

3. Pressure Compensator Tuning: This model features a pressure compensator set at 230 bar. The compensator pressure set point can be adjusted via the adjustment bolt. Perform initial settings under no-load conditions, then gradually increase load to target pressure with fine adjustments. The compensator adjustment range covers 1885–4641 psi (approx. 130–320 bar).

4. Initial Start-Up & Priming: Before first start-up, pre-lubricate the pump by filling the housing with clean hydraulic fluid through the case drain port. Perform a brief jog start (5–10 seconds) to check for abnormal noise, leakage, or excessive vibration. Then正式 start the pump and run at low load for several minutes to purge air from the pump and system lines.

5. Case Drain Port Positioning & Pressure Monitoring: During installation, ensure the drain port is positioned higher than the pump body to prevent oil starvation in the pump chamber after shutdown. Maximum case pressure is 280 bar. The PVM141’s large displacement (141 cc) means higher case drain flow—ensure the drain line has adequate diameter to avoid excessive back pressure.

6. Scheduled Maintenance & Filter Replacement: Follow the maintenance intervals specified in the Vickers PVM Series service manual. Pay particular attention to filter condition, fluid cleanliness, and seal integrity during routine inspections. Periodically verify the adjustable maximum displacement stop setting to ensure it has not been inadvertently altered.
