Product Overview
The PVM045ER06CS2A315000000AB is a Vickers (now Danfoss) PVM Series open-circuit swashplate-type axial piston variable displacement pump. The PVM Series is Vickers’ classic product line, covering displacements from PVM018 through PVM141. The PVM045 delivers a maximum displacement of 45.1 cm³/rev.
This model features an ER control configuration — Pressure Compensator control with right-hand rotation. CS2 is the shaft type and specification code, A3 is the main port type and location code. The “15” code indicates specific functional options including an adjustable maximum displacement stop. 000000AB is the serial number and manufacturing 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 (2-Bolt SAE B Flange, SAE J744-101-2). 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-Compensated (Constant Pressure) Control for Stable System Pressure
The ER control configuration features pressure-compensated variable control as standard, automatically adjusting the swashplate angle in response to system pressure changes to modulate output flow. When system pressure reaches the compensator set point, the pump automatically reduces displacement to maintain constant pressure. The compensator adjustment range covers 1885–4641 psi, accommodating various system pressure requirements. The pressure cut-off characteristic ensures that once the set pressure is reached, the pump only delivers the minimal flow required to maintain pressure, significantly reducing overflow losses and system heat generation.
2. Exceptional Low-Noise Design for Improved Working Conditions
The PVM Series pumps excel in noise control, achieving a noise level of just 64 dB. The PVM Series employs a 3-piece construction (flange, housing, and valve block) with a bimetallic distribution plate, systematically reducing both fluid-borne and structure-borne noise. This represents a noise reduction of up to 50% compared to同类 products. This low-noise design not only improves operator working conditions but also reduces environmental noise pollution, making it particularly suitable for industrial facilities with stringent noise emission requirements.
3. High Pressure Ratings & Long-Life Bearings for Long-Term Reliability
The PVM045 delivers a continuous operating pressure of 280 bar (4000 psi) with peak pressures up to 350 bar (5075 psi) . Under rated pressure conditions, bearing life reaches 8000 hours. The combination of high-strength cast iron housing and ductile iron end cover, together with rigorously proven rotating groups, ensures long-term reliability under continuous high-load operation.
4. Proven Rotating Group Design with Low Maintenance Costs
The PVM Series features proven rotating group designs that enable stable long-term operation at continuous working pressures of 280 bar. Optimized friction pair designs and precision manufacturing processes ensure high volumetric efficiency and low internal leakage, effectively reducing maintenance frequency and operating costs.
5. Compact Power Density with Flexible Mounting Configurations
The PVM045 weighs approximately 24 kg, offering favorable power density within its displacement class. The 2-Bolt SAE B flange mounting with 13T splined shaft configuration ensures compatibility with major global hydraulic systems. The PVM Series complies with SAE and ISO international standards, offering excellent interchangeability in the global market.
6. Pro-FX Control System Compatible – Ready for Intelligent Upgrades
The PVM Series pumps support Pro-FX control systems, facilitating integration with advanced electronic control architectures. This feature enables the PVM045 to meet the intelligent and networked upgrade requirements of hydraulic systems in the Industry 4.0 era.

Expert Maintenance Tips
Model Confirmation & Pre-Installation Inspection: Prior to installation, confirm the complete model code as PVM045ER06CS2A315000000AB. This model features 2-Bolt SAE B flange mounting (SAE J744-101-2) with a 13T splined shaft. Ensure alignment between the pump and drive mechanism meets SAE mounting standards to prevent premature bearing wear due to misalignment. Manually rotate the shaft before installation to confirm smooth, obstruction-free rotation. Pump body levelness deviation should be ≤ 0.1 mm/m.
Suction Line & Fluid Cleanliness Control: The PVM Series recommends a filtration rating of ISO 18/13. Suction lines should be as short and large in diameter as possible, with minimal bends; suction vacuum should be ≤ 0.07 bar to prevent cavitation. Suction filter rating should be ≥ 100 μm. Complete system flushing is mandatory before initial start-up.
Pressure Compensator Tuning: The ER control configuration is pressure compensator control. Compensator settings should not exceed the pump’s rated pressure range. The compensator adjustment range is 1885–4641 psi. Perform initial settings under no-load conditions, then gradually increase load to target operating conditions with fine adjustments. The pressure compensator’s cut-off characteristics should be verified at 50 °C (120 °F) static conditions.
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.
Fluid Temperature Control: The cold start temperature limit is 104 °C. It is recommended to allow the fluid to reach normal operating temperature (approx. 30–60 °C) before loading to rated conditions, to prevent cavitation and wear caused by low-temperature high viscosity.
Scheduled Maintenance & Filter Replacement: Follow the maintenance intervals specified in the Vickers PVM Series Service Manual (E-PUIO-II001-E3). Pay particular attention to filter condition, fluid cleanliness, and seal integrity during routine inspections. Regular hydraulic fluid and filter replacement is essential for long-term reliable pump operation.
