PVG100 PVG130 Series Piston Pump FAQ:

1. What is the PVG100 PVG130 Series Piston Pump ?

• Differentiated high-pressure performance

  PVG100 supports continuous 345 bar high pressure for heavy-load machinery; PVG130 delivers larger displacement (130 cc/rev) with 258 bar rated pressure, both reach max continuous speed 2400 rpm to match high-flow demand.

• Ultra-fast four-way pilot proportional control

  Instant response to system flow/pressure commands with low hysteresis, stable output across full displacement range, ideal for high-cycle working equipmentOilgear.

• Patented hard-on-hard wear-resistant rotating group

  Hardened cylinder barrel, valve plate and piston shoes form friction pairs, greatly boosting contamination resistance and service life; compatible with low-viscosity special hydraulic fluidsOilgear.

• Pressure-lubricated swashblock & polymer bearings

  Self-lubricating saddle bearings eliminate frequent wear failures, reduce maintenance frequency and noise during long-hour continuous operation.

• Rich modular control options

  Load sensing, pressure compensation, horsepower limiting and volume stop controls are interchangeable on-site without disconnecting piping, flexible to match mobile and industrial systems.

• Compact SAE heavy-duty mounting design

  Splined/keyed drive shaft with strong through-torque capacity; optional through-drive structure for multi-pump tandem assembly, saving installation space on vehicle chassisOilgear.

• High efficiency & low pulsation

  Volumetric efficiency over 93%, low flow pulsation and running noise, cutting energy consumption for all-day heavy-duty operations.
  
  

3. What is the working pressure range of PVG100 PVG130 Series Piston Pump ?

4. Can PVG100 PVG130 Series Piston Pump Pump replace other brands?

1. Direct replacement for original Oilgear PVG100 / PVG130Our PVG100 and PVG130 pumps are fully interchangeable with genuine Oilgear PVG series pumps. They adopt identical SAE mounting flange, drive spline, port layout, displacement and control interface. No mechanical modification is required when replacing original Oilgear units, and all system control functions remain consistent.
2. Compatible alternative for Danfoss equivalent PVG pumpsIf the suffix model codes (control type, through-drive, port position) match, our PVG100/PVG130 can directly replace Danfoss PVG100/130 pumps without chassis or piping adjustment.
3. Limitations for other brand pumps (Rexroth, Parker, Eaton, etc.)It cannot serve as a direct drop-in replacement for variable piston pumps from Rexroth, Parker, Eaton, Kawasaki or other different series brands. Their mounting dimensions, shaft specifications, control valve structures and pressure flow curves differ greatly. If you want to replace these brands, you need to modify the mounting bracket, oil pipeline and adjust the hydraulic control program.
4. Pre-check before replacementConfirm 4 key parameters: maximum displacement, continuous working pressure, control mode (load sensing / pressure compensator), through-drive structure and port position to guarantee seamless replacement.
   
   

5. What hydraulic oil is recommended for PVG100 PVG130 Series Piston Pump ?

• Primary Recommended FluidStandard anti-wear mineral hydraulic oil conforming to ISO HM / DIN HLP anti-wear grades is the first choice for PVG100 and PVG130 pumps.Preferred viscosity grades: ISO VG46, ISO VG68.
• Viscosity Operating Window

  Normal working kinematic viscosity: 16–36 mm²/s (at operating temperature)

  Cold startup allowable viscosity: ≤1000 mm²/s

  Do not operate continuously above 1000 mm²/s to avoid pump damage.

• Operating Temperature Range

  Continuous safe oil temperature: -20 ℃ ~ +80 ℃

  Transient peak temperature: ≤95 ℃; auxiliary cooling required for long-time full-pressure operation.

• Seal Matching Tips

     Standard unit: NBR (Buna Nitrile) seals for mineral oil

     High-temperature / phosphate ester fluid: Upgrade to FKM Viton seals

     Low-temperature environments: Optional EPR seals

6. What is the typical speed range of PVG100 PVG130 Series Piston Pump ?

• Minimum stable operating speed: 600 rpm

  Smooth flow output without pulsation or cavitation under normal inlet pressure; prolonged operation below 600 rpm will cause insufficient internal lubrication and accelerated wear.

• Standard rated test speed: 1800 rpm

  All official flow, power and efficiency data are calibrated at 1800 rpm.

• Maximum continuous allowable speed: 2400 rpm

  Both PVG100 and PVG130 share the same upper continuous speed limit; long-term running over 2400 rpm is forbidden without factory approval.

• Extra note

  Custom higher speeds over 2400 rpm can be supported only after technical consultation with the manufacturer. Do not idle at zero displacement for more than 30 minutes continuously at any speed.
