Key Technical Advantages

Pilot-Operated Pressure Control with Ultra-Low Hysteresis
The PV7 series employs a precision pilot-operated pressure controller mechanism, where a small reciprocating control piston (10) and a large reciprocating control piston (11) work in coordination. When system pressure reaches the set value, the regulator spool (14) shifts against the spring force, connecting the chamber behind the large actuating piston to the tank for unloading. The small actuating piston (10), continuously pressurized by system pressure, moves the stator ring (4) nearly to the central position, maintaining pressure while flow drops to near zero — only compensating for leakage. This pilot control mechanism produces a vertical qV-p characteristic curve that shifts in parallel at different pressure settings, delivering extremely low hysteresis, exceptional repeatability accuracy, and minimal pressure fluctuation. Very short on-stroke and off-stroke control times (millisecond-level response) make it ideal for frequent start/stop and precision control scenarios. When combined with proportional valves, closed-loop control accuracy within ±1% is achievable.

Hydrodynamically Lubricated Plain Bearings
The PV7 series features hydrodynamically lubricated plain bearing design, where a complete oil film forms between bearing surfaces during operation, preventing direct metal-to-metal contact. This design fundamentally eliminates the fatigue failure mode inherent in traditional rolling element bearings under alternating loads, extending bearing life by 2 to 3 times compared to conventional designs while significantly reducing operational noise. The bearing’s high reliability provides extremely long maintenance-free intervals in continuous duty applications such as machine tool power units and constant pressure systems.

Axial Compensation Displacer with High Volumetric Efficiency
The PV7 series displacer employs axial compensation technology that automatically maintains optimal face clearance during operation. Even under high-pressure conditions, the displacer maintains intimate contact with the rotor face, effectively minimizing face leakage and delivering volumetric efficiency up to 92%. This design ensures the pump sustains high efficiency throughout its entire service life without the dramatic efficiency degradation seen in certain pump types. At zero stroke (pressure holding) condition, power consumption drops to an absolute minimum — only maintaining system pressure and compensating for leakage — achieving 30% to 50% energy savings compared to fixed displacement pump systems.

Low Noise & Low Flow Pulsation Design
The PV7 series achieves industry-leading flow pulsation levels through specially designed vane geometry and stator inner curve profiles. The adjustable displacement design delivers low pulsation flow and achieves very high repetition accuracy with low pressure peaks during down-control. Operating noise is further optimized via the height adjustment screw (7), delivering noise levels 3 to 5 dB(A) lower than comparable gear pumps. This characteristic makes the PV7 series particularly suitable for noise-sensitive indoor industrial environments such as precision machine tool shops, injection molding facilities, and medical equipment applications.

Modular Combination & Flexible Expansion
Standard PV7 series single pumps can be flexibly combined into multiple pump configurations, supporting tandem mounting with internal gear pumps, external gear pumps, axial piston pumps, and radial piston pumps via through-drive capability. This design eliminates the need for additional motors and drive couplings, significantly reducing installation space and cost while providing valuable circuit design flexibility. Available as complete integrated units — no drive coupling or pump bracket required.

Expert Maintenance Tips

Commissioning & Air Bleeding: All PV7 series pumps are self-priming, but the housing must be filled with hydraulic oil before initial startup. Prefill the housing through the case drain port, then jog the motor until continuous bubble-free oil flow is achieved. If the pump fails to deliver bubble-free oil within approximately 20 seconds, inspect the suction line for air leaks.
No-Load Warm-Up: After startup or extended shutdown, the pump must be started under no-load conditions, allowing hydraulic fluid to flow at zero pressure for several seconds to ensure adequate lubrication. Observe the motor and pump rotation direction arrows. Run at no-load for 5 to 10 minutes until oil temperature reaches 30°C before gradually applying load. Never operate the pump without hydraulic fluid!
Fluid Cleanliness Control: Maintain hydraulic oil cleanliness at ISO 4406 20/18/15 or better. The pilot controller’s precision spool and piston clearances are extremely tight — particulate contamination can cause controller sticking or sluggish response. Install an appropriate precision filter on the return line and inspect or replace the filter element every 250 hours. Effective filtration prevents failures and simultaneously extends component service life.
Viscosity & Temperature Management: Recommended fluid: ISO VG 32–68 anti-wear hydraulic oil (HLP). At operating temperature, maintain fluid viscosity within 16–160 mm²/s. Continuous oil temperature must not exceed 70°C. During cold starts, fluid viscosity may exceed the upper limit (maximum allowable starting viscosity: 800 mm²/s) — the pump must be warmed up at low speed and low pressure before loading to rated conditions.
Shaft Alignment: Pump-to-driver concentricity must be controlled within φ0.1 mm. A flexible coupling is strongly recommended. The PV7 series drive shaft cannot withstand radial or axial external forces — installation must ensure the shaft end is free from constraint. Tighten flange mounting bolts in a diagonal pattern to ensure reliable face sealing.
Case Drain Line Requirements: The case drain line must be piped independently back to the reservoir. Case drain back-pressure must not exceed 2 bar. The drain line outlet must be submerged below the minimum oil level in the tank. When combining multiple pumps, individual drain lines must be used — never merge drain lines, as pressure differentials can damage seals.
Height Adjustment Screw Optimization: The height adjustment screw (7) on the PV7 series is used to optimize operating noise. During system commissioning, fine-tune this screw to find the optimal noise point. Do not over-tighten, as this may restrict the stator ring’s maximum eccentricity and reduce flow output.
Pressure Controller Setting: At factory delivery, flow and zero stroke pressure are typically set to the maximum values for the respective size. If specific settings are required, state them clearly at the time of order, or have qualified personnel adjust via the setting screw (6) in the field. Note: turning the adjustment screw clockwise increases operating pressure; turning counter-clockwise reduces it.
