Product presentation
Product Type: Axial piston variable pump with swashplate (A10VSO series), Rexroth classic open circuit high-pressure variable piston pump, imported from Germany
Control Method: DRS control (pressure + flow dual control, with remote pressure control), capable of achieving constant pressure, constant flow, and load-sensitive combined control, suitable for harsh industrial hydraulic and construction machinery conditions
II. Core Technical Parameters
1. Displacement and Flow
Nominal displacement: 100 cm³/r (100 mL/r)
Maximum rotational speed: 2600 r/min
Common rotational speed 1450 r/min: Theoretical flow rate 145 L/min; 1800 r/min: Theoretical flow rate 180 L/min
2. Pressure Parameters
Rated working pressure: 315 bar (31.5 MPa)
Peak pressure: 350 bar (35 MPa)
Control pressure range: 20–315 bar, remote pressure control function
3. Medium and Environment
Applicable medium: Mineral hydraulic oil HLP (DIN51524), water glycol, synthetic hydraulic oil
Oil temperature range: -20℃ to +80℃
Oil cleanliness: NAS ≤ 9 grade / ISO 4406 19/17/14
Viscosity range: 20–380 mm²/s (cSt)
4. Structure and Installation
Installation form: Flange installation (32R series right rotation)
Shaft end form: Flat key shaft, can be driven by other pumps in series
Weight: Approximately 42 kg
Sealing material: Standard NBR nitrile rubber, optional FKM fluororubber (resistant to high and low temperatures, chemical corrosion)
III. Product Features
High pressure and high efficiency: 315 bar continuous high-pressure working condition, volumetric efficiency ≥ 94%, total efficiency ≥ 90%, excellent energy-saving performance
DRS combined control: Integrated pressure compensation + flow compensation + remote pressure control, output flow and pressure as needed, reducing energy consumption and heat generation
Low noise and long life: Optimized swashplate structure, ceramic valve plate, wear-resistant piston, resistant to impact and pollution, suitable for heavy-load high-frequency start-stop
High versatility: 32R right-hand flange, standard oil ports, can be directly replaced with the same specification A10VSO series pumps, suitable for most hydraulic systems
Reliable protection: Shell made of high-strength ductile iron, resistant to vibration and corrosion, suitable for harsh environments in mines, metallurgy, and construction machinery
IV. Typical Application Domains
Industrial hydraulic: Injection molding machines, die-casting machines, forging machines, hydraulic stations, large-scale automated production lines
Construction machinery: Cranes, concrete pump trucks, aerial work platforms, mining machinery
Energy / Metallurgy: Wind power hydraulic systems, metallurgical rolling mills, ship hydraulic systems
V. Model Suffix Meaning (Key)
DRS: Pressure + flow combined control, with remote pressure control
32R: Installation series + right-hand rotation direction
VPB12N00: Oil port configuration, sealing form, driven by shaft, without additional valve group
S1439: Customized special configuration (suitable for specific equipment working conditions)
