2. Key Technical Parameters
2.1 Pressure & Speed
|
Parameter
|
Value
|
Remarks
|
|
Maximum Intermittent Pressure
|
P1 (Front Section): Up to 300 bar; P2 (Rear Section): Up to 320 bar
|
Each cartridge bears pressure independently, pressure can be flexibly set according to specific circuit requirements
|
|
Maximum Continuous Pressure
|
P1 (Front Section): Up to 270 bar; P2 (Rear Section): Up to 290 bar
|
It is recommended not to exceed the continuous pressure for long-term operation to extend the service life of the pump
|
|
Speed Range
|
550 – 2300 rpm (industrial type); 450 – 2100 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. 420 rpm
|
Ensures sufficient lubrication of vanes and stable output, effectively avoiding vane wear and abnormal noise
|
|
Volumetric Efficiency
|
Typically 0.93 – 0.95
|
High volumetric efficiency reduces energy loss and system heat generation, significantly saving operating costs
|
|
Noise Level
|
4 – 6 dB(A) lower than ordinary double vane pumps
|
Optimized vane and cam ring design, ultra-low pressure pulsation (±1.5 bar), reducing pipeline vibration and noise pollution

2.3 Other Key Parameters
-
Contamination Resistance: Enhanced double-lip vane design further reduces sensitivity to hydraulic oil cleanliness (NAS 6 grade or higher is recommended for optimal performance)
-
Temperature Range: -25°C ~ +85°C (adjust according to hydraulic oil type, extendable to -35°C with special low-temperature oil)
-
Shaft Type: Keyed shaft (SAE F) or splined shaft (SAE CC/SAE D/F) optional, higher torque-bearing capacity than T67DC series
-
Rotation Direction: Standard clockwise (R), counterclockwise (L) optional; both two cartridges rotate synchronously with stable transmission
-
Seal Type: Standard Nitrile Rubber (NBR); Viton, EPDM or PTFE seal materials optional based on specific working conditions and medium
-
Flow Rate: Up to 370 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 12 ~ 110 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 even under high-pressure and harsh conditions
-
Application Fields: Heavy-duty industrial machinery, high-pressure hydraulic systems, complex dual-circuit equipment (e.g., large-scale plastic machinery, metallurgical smelting equipment, heavy engineering machinery, marine equipment)
4. Core Features
-
Independent Double-circuit Output: Two cartridges work independently, providing two different pressure/flow combinations simultaneously to meet the needs of complex high-pressure dual-circuit systems
-
High Efficiency & Energy Saving: Full pressure balance design with high volumetric efficiency, effectively reducing energy loss and operating costs in long-term operation
-
Easy Maintenance: Cartridge design allows quick and independent replacement of any cartridge, reducing downtime and maintenance costs by approximately 65%
-
