Technical Analysis of T6DR Series Drive Train Vane Pump
I. Key Product Features
1. Modular Design Architecture
• The T6DR series is part of Denison's T6 vane pump family, utilizing C/D/E housing specifications. By combining pump elements with varying displacements (e.g., T6D series displacement range of 48-158 ml/rev), it forms a comprehensive product line covering 10-227 ml/rev.
• Example model T6DR-031-1R00-B10-A1 demonstrates its standardized nomenclature, facilitating rapid selection based on user requirements.
2. Extreme Performance Parameters
• Pressure Capability: Rated operating pressure up to 275 bar (280 bar for certain models), reducing installation costs through minimized hydraulic component dimensions.
• Efficiency Performance: Achieves 94% volumetric and mechanical efficiency, enabling operation as low as 600 rpm under full pressure (400 rpm for mobile applications).
• Operational Adaptability: Supports -30°C cold starts (2000 cSt viscosity) without stall risks, with pressure pulsation controlled within ±2 bar.
3. Silent Operation & Contamination Resistance
• Employs 12-vane configuration and dual-lip vane design, reducing flow pulsation by 60% and noise levels by 5-8 dB(A) compared to competitors.
• Contamination resistance certified to ISO 4406 19/16/13 cleanliness, extending vane life to over 8000 hours.
4. Installation Flexibility
• Offers SAE J744a/ISO 3019-1 flange interfaces with support for parallel/spline drive shafts.
• Dual-pump configurations allow 32 installation combinations, while triple-pump options reach 128 combinations, with 4-way adjustable port orientations.

• Modular design reduces maintenance time by 60%, with pump element replacement without pipeline disassembly.
2. Customized Solutions
• 3D selection software generates pump-motor-valve matching schemes based on input parameters.
• Special coatings (e.g., nickel-phosphorus) for marine corrosion resistance, passing 1000-hour salt spray tests.
3. Industry Certifications
• ABS, DNV, CCS class approvals with ISO 8846 explosion-proof compliance.
• Food-grade models certified to NSF H1 for direct contact with edible oils.
V. Typical Application Cases
• Case 1: Energy-Saving Retrofit for Injection Molding
Replacing a gear pump with T6DR-158 reduced clamp pressure pulsation from ±5 bar to ±1.2 bar, shortening cycle time by 0.3 seconds and saving 150,000 kWh annually.
• Case 2: Arctic Research Vessel Hydraulic System
Operating at -40°C with T6DR-269 and低温 hydraulic oil achieved ≤0.8-second steering response with pressure stability优于±1.5 bar.
VI. Selection & Maintenance Guidelines
1. Key Selection Steps
• Calculate required flow: Q(L/min) = Displacement(ml/rev) × Speed(rpm)/1000 × Volumetric Efficiency
• Verify power matching: P(kW) = Pressure(bar) × Flow(L/min)/600
2. Maintenance Recommendations
• Change hydraulic oil after initial 50 hours, then every 2000 hours with oil cleanliness checks.
• Replace pump elements when vane wear exceeds 0.1 mm, with comprehensive inspections every 5000 hours.
