Up to 280 bar / Up to 280 bar
|
Intermittent operation duration: ≤ 10% of total operating time; avoid prolonged intermittent pressure to protect vane and bearing
|
|
Maximum Continuous Pressure
|
Up to 250 bar / Up to 250 bar
|
Recommended for long-term operation; stable pressure output ensures system reliability and extends pump service life
|
|
Speed Range
|
500 – 2400 rpm / 500 – 2400 rpm (industrial type); 400 – 2200 rpm (heavy-duty working conditions)
|
Displacement and speed are inversely proportional; higher displacement requires lower maximum operating speed
|
|
Minimum Stable Speed
|
Approx. 380 rpm / Approx. 380 rpm
|
Ensures adequate lubrication of internal components, prevents vane jamming and abnormal noise during low-speed operation
|
|
Volumetric Efficiency
|
Typically 0.92 – 0.94 / Typically 0.92 – 0.94
|
High volumetric efficiency minimizes energy loss and system heat generation, reducing overall operating costs
|
|
Noise Level
|
≤ 75 dB(A) @ 1800 rpm / ≤ 74 dB(A) @ 1800 rpm
|
Optimized vane and cam ring profile, low pressure pulsation (±2.0 bar), reducing pipeline vibration and noise pollution

2.3 Other Key Parameters
-
Contamination Resistance: Single-lip vane with wear-resistant coating reduces sensitivity to hydraulic oil cleanliness (NAS 7 grade or higher is recommended for optimal performance; NAS 6 grade for harsh conditions)
-
Temperature Range: -20°C ~ +80°C (T7EB / T7EBS); adjustable to -30°C with special low-temperature hydraulic oil, suitable for most industrial environments
-
Shaft Type: Keyed shaft (SAE F) as standard; splined shaft (SAE CC/SAE D) optional for both series, with strong torque-bearing capacity
-
Rotation Direction: Standard clockwise (R); counterclockwise (L) optional, stable transmission and consistent output during operation
-
Seal Type: Standard Nitrile Rubber (NBR); Viton, EPDM or PTFE seal materials optional based on working conditions and hydraulic medium
-
Flow Rate: Up to 250 L/min @ 2000 rpm (varies by displacement size; T7EBS has the same flow capacity as T7EB with the same displacement)
3. Applicable Medium & Environment
-
Applicable Medium: Mineral oil, biodegradable oil, water-based hydraulic fluid, etc.; recommended viscosity 10 ~ 100 cSt for stable operation
