2. Key Technical Parameters
2.1 Pressure & Speed
|
Parameter
|
Value
|
Remarks
|
|
Maximum Intermittent Pressure
|
P1 (Front Section): Up to 280 bar; P2 (Rear Section): Up to 300 bar
|
Each cartridge bears pressure independently, pressure can be set according to circuit requirements
|
|
Maximum Continuous Pressure
|
P1 (Front Section): Up to 250 bar; P2 (Rear Section): Up to 270 bar
|
It is recommended not to exceed the continuous pressure for long-term operation to extend service life
|
|
Speed Range
|
500 – 2200 rpm (industrial type); 400 – 2000 rpm (heavy-duty working conditions)
|
The larger the displacement, the lower the maximum speed; P1 displacement determines the overall speed upper limit
|
|
Minimum Stable Speed
|
Approx. 400 rpm
|
Ensures sufficient lubrication of vanes and stable output, avoiding vane wear
|
|
Volumetric Efficiency
|
Typically 0.92 – 0.94
|
High volumetric efficiency reduces energy loss and system heat generation, saving operating costs
|
|
Noise Level
|
3 – 5 dB(A) lower than ordinary double vane pumps
|
Optimized vane and cam ring design, low pressure pulsation (±2 bar), reducing pipeline vibration

2.3 Other Key Parameters
-
Contamination Resistance: Double-lip vane design reduces sensitivity to hydraulic oil cleanliness (NAS 7 grade or higher is recommended)
-
Temperature Range: -20°C ~ +80°C (adjust according to hydraulic oil type, extendable to -30°C with special oil)
-
Shaft Type: Keyed shaft (SAE E) or splined shaft (SAE CC/SAE D/E) optional, high torque-bearing capacity
-
Rotation Direction: Standard clockwise (R), counterclockwise (L) optional; both two cartridges rotate synchronously
-
Seal Type: Standard Nitrile Rubber (NBR); Viton or EPDM seal materials optional based on working conditions
-
Flow Rate: Up to 350 L/min @ 2000 rpm (varies by displacement combination of P1 and P2)
3. Applicable Medium & Environment
-
Applicable Medium: Mineral oil, biodegradable oil, water-based hydraulic fluid, etc.; recommended viscosity 10 ~ 100 cSt
-
Applicable Fluids: Fire-resistant fluids and biodegradable fluids (including phosphate esters, organic esters, chlorinated hydrocarbons, water glycols, rapeseed oil) are acceptable, ensuring longer service life at higher pressures
-
Application Fields: Industrial machinery, heavy-duty equipment, complex hydraulic systems requiring two different pressure/flow combinations (e.g., plastic machinery, metallurgical equipment, engineering machinery)
4. Core Features
-
Independent Double-circuit Output: Two cartridges work independently, providing two different pressure/flow combinations simultaneously to meet the needs of complex dual-circuit systems
-
High Efficiency & Energy Saving: Full pressure balance design with high volumetric efficiency reduces energy loss and operating costs
-
Easy Maintenance: Cartridge design allows quick and independent replacement of any cartridge, reducing downtime and maintenance costs by approximately 60%
-
Flexible Installation: 80 port position combinations adapt to various system layouts, compact structure saves installation space
-
Low Pulsation Output: Optimized vane structure design with low pressure pulsation, reducing pipeline noise and protecting the hydraulic system components
