Product Overview
The PVM018ER05CS1A315000000AB (Eaton material number 123AL00095B) is a Vickers (now Danfoss) PVM Series open-circuit swashplate-type axial piston variable displacement pump. The PVM Series is Vickers’ classic industrial hydraulic pump line, with the PVM018 representing the smallest displacement model in the series. This model delivers a maximum displacement of 18.0 cm³/rev.
This model features Pressure Compensator control. The 315 in the model code denotes a pressure compensator setting of 315 bar (4568 psi). R indicates right-hand rotation (clockwise when viewed from the shaft end). 05 denotes the SAE straight keyed shaft specification. CS1 is the mounting flange and port configuration code, indicating Side Ported configuration.
The PVM Series comes standard with an adjustable maximum displacement stop and single shaft seal. The housing is cast iron and the end cover is ductile iron. This model is compatible with mineral hydraulic oils and phosphate ester fire-resistant fluids.
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 315 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. The pressure compensator adjustment range covers 1885–4641 psi (approx. 130–320 bar).
2. 8,000-Hour Bearing Life for Long-Term Reliability
The PVM018 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. 64 dB Ultra-Low Noise Operation
The PVM Series delivers an operating noise level of just 64 dB—50% less noise than comparable products. The bimetallic timing plate improves pump filling characteristics, reducing fluid noise and extending pump service life. The water-drop shaped housing design further reduces vibration and noise.
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. Pressure lubrication channels further reduce wear and support internal loads.
5. Adjustable Maximum Displacement Stop with Gauge Ports for Easy Commissioning
The PVM Series comes standard with an adjustable maximum displacement stop and single shaft seal. The pump body features inlet/outlet pressure gauge ports and a maximum displacement stop adjustment screw for convenient on-site commissioning without additional valve components.
6. Broad Fluid Compatibility with Flexible Port Configurations
The PVM Series is compatible with standard anti-wear hydraulic oils, synthetic fluids, high-water-content fluids, and phosphate ester fire-resistant fluids. Available with side or end ports and multiple drain ports to accommodate various mounting orientations.

Expert Maintenance Tips
Model Confirmation & Pre-Installation Inspection: Prior to installation, confirm the complete model code as PVM018ER05CS1A315000000AB with Eaton material number 123AL00095B. This model features 2-Bolt SAE B flange mounting with an SAE straight keyed shaft. The pump weighs approximately 15 kg (33 lb) . Manually rotate the shaft before installation to confirm smooth, obstruction-free rotation. Strictly control coupling coaxiality—misalignment will quickly damage pump bearings.
Fluid Cleanliness Control: Recommended filtration rating is ISO 18/13, with a 10 μm filter recommended. Cold start temperature limit is 104 °C. Complete system flushing is mandatory before initial start-up.
Pressure Compensator Tuning: This model features a pressure compensator set at 315 bar. The compensator pressure set point can be adjusted via the adjustment bolt. The compensator adjustment range covers 1885–4641 psi (approx. 130–320 bar). During adjustment, install a 0–350 bar (0–5000 psi) pressure gauge in the outlet gauge port and limit the pressure setting to the pump’s continuous rated pressure. Perform initial settings under no-load conditions, then gradually increase load to target pressure with fine adjustments.
Initial Start-Up & Priming: Before first start-up, pre-lubricate the pump by filling the housing with clean hydraulic fluid through the highest case drain port. Perform a brief jog start (5–10 seconds) to check for abnormal noise, leakage, or excessive vibration. Then start the pump and run at low load for 5 to 10 minutes to purge air from the pump and system lines. Air in the pump will cause explosive noise, insufficient flow, and component damage.
Case Drain Port Positioning & Pressure Monitoring: The PVM Series housing features multiple drain ports for various mounting orientations. During installation, ensure at least one drain port is positioned higher than the pump body to prevent oil starvation in the pump chamber after shutdown. The case drain line must return to the tank independently—do not combine with the return line. Continuous case pressure must not exceed 2 bar absolute—exceeding this will damage the shaft seal. Maximum case peak pressure is 350 bar.
Load Sensing Function (if applicable): If the pump is configured with Load Sensing (LS) functionality, keep LS feedback lines as short as possible and retain the internal Φ0.7 damping orifice—do not block it. When LS function is not in use, the LS port must not be left open—connect it to system high-pressure oil.
Scheduled Maintenance & Filter Replacement: Follow the maintenance intervals specified in the Vickers PVM Series Service Manual (E-PUIO-II001-E4). 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.
