T6DM-B50-1R00-C1 Denison Single Vane Pump 158 ml/r 210 bar

Product Overview

The T6DM, T6ED, and T6CC Series, manufactured by Parker Denison, are renowned fixed-displacement vane pump product lines celebrated for their high-pressure capability, wide speed range, and compact design.

The T6DM Series is the mobile version of the T6D single vane pump, with displacement ranging from 47.6 to 158.0 ml/r. The T6DM-B50-1R00-C1 is equipped with a B50 cartridge, delivering 158.0 ml/r displacement—the maximum displacement in the T6D housing family.

The T6ED Series is a double vane pump combining T6E housing (Section 1) and T6D housing (Section 2). The T6ED-057-042-1R02-B1 features 057 (183 ml/r) and 042 (136 ml/r) cartridges, with a total displacement of 319.3 ml/r.

The T6CC Series is a double vane pump integrating two T6C housing sections into a single housing. The T6CC-025-012-2L00-C111 features 025 (79 ml/r) and 012 (37 ml/r) cartridges, with a total displacement of 116.4 ml/r.

The T6 Series features a balanced-type fixed-displacement design, fully balancing radial hydraulic forces for long bearing life and smooth operation. The series utilizes Denison’s patented pin-vane (double-lip) technology, minimizing noise levels and improving volumetric efficiency.

Our products are manufactured to be 100% interchangeable with Parker Denison original specifications—a true “drop-in” replacement solution. Every unit undergoes 100% full-load and flow-matching testing under simulated operating conditions before shipment, ensuring volumetric efficiency, flow rate, and noise performance meet or exceed original specifications at rated pressure.

Key Technical Advantages

1. Pin-Vane (Double-Lip) Patent Technology – Exceptional Contamination Resistance
The Denison T6 Series features a unique pin-vane (double-lip) structure design. Outlet pressure is continuously applied to the pin, providing a steady, light force against the vane. The top and bottom areas of the vane are subject to the same pressure (either inlet or outlet pressure, depending on the vane’s location during rotor rotation). This design minimizes noise levels and improves volumetric efficiency while providing exceptional contamination resistance.

2. Balanced-Type Design – Extended Bearing Life
The T6 Series employs a balanced-type hydraulic design, fully balancing radial hydraulic forces and eliminating radial loads on the rotor. This dramatically reduces bearing stress, significantly extending bearing life and ensuring long-term stable operation under high-pressure conditions.

3. Ultra-High Pressure Capability in a Compact Envelope
The T6 Series achieves operating pressures up to 275 bar within a compact housing size. T6CC Series reaches up to 275 bar, T6ED Series up to 240 bar, and T6DM Series up to 210 bar. High-pressure capability allows the use of smaller actuators and lines, reducing overall system cost and installation footprint.

4. Cartridge Design for Rapid Maintenance
The T6 Series features cartridge-type construction, allowing individual pump cartridges (cam ring, rotor, vanes, plates) to be replaced quickly and independently. On-site repairs or displacement changes can be completed in minutes without removing the entire pump from the system.

5. Double Pump Design – Single Power Source, Dual-Circuit Independent Control
The T6ED and T6CC double pumps integrate two pumping sections into one housing driven by a single shaft. This design allows a single power source to simultaneously serve two independent hydraulic circuits, or provide greater total flow through combined delivery.

6. Wide Speed Range and Cold-Start Capability
The T6 Series supports a wide speed range of 600–2800 r/min. T6DM Series reaches speeds up to 2200 r/min. The pumps operate reliably even at low speeds and across a wide viscosity range, permitting cold starts and hot operation.

7. 100% Drop-In Interchangeability – Zero Retrofit Cost
Manufactured to exact Parker Denison original specifications—mounting dimensions, port locations, and shaft configurations are identical to the original. Mounting complies with SAE J744c 2-bolt flange standards. No piping modifications or installation adapters are required for direct replacement.

Expert Maintenance Tips

1. Model Identification and Selection

• T6CC-025-012-2L00-C111: T6CC = T6C + T6C double combination, 025 = Section 1 cartridge (79 ml/r), 012 = Section 2 cartridge (37 ml/r), 2 = Splined shaft, L = Counter-clockwise, 00 = Port position, C111 = NBR special seal.

• T6C Available Cartridge Codes: 003(10.8), 005(15.9), 006(18.9), 008(26.7), 010(34.1), 012(37.1), 014(46.0), 017(58.3), 020(63.8), 022(70.3), 025(79.3), 028(88.8), 031(100.0) ml/r.

2. Installation Precautions

• Verify pump rotation direction matches system requirements—R denotes clockwise, L denotes counter-clockwise (viewed from shaft end).

• Confirm shaft type matches—T6DM/T6ED Code 1 is straight/keyed shaft; T6CC Code 2 is splined shaft.

• T6DM and T6ED use SAE C 2-Bolt Flange mounting; T6CC uses SAE B 2-Bolt Flange mounting.

• Suction piping should be as short as possible, minimizing unnecessary restrictions.

• The pump housing must not bear piping loads; suction and discharge lines must have independent supports.

3. Pre-Startup Checklist

• Verify oil level in the reservoir is adequate and fluid type is correct (ISO VG32, VG46, or VG68 anti-wear hydraulic oil recommended).

• Confirm all piping connections are secure with no leakage.

• Prime the pump by filling the housing with oil before first startup to prevent dry running.

• Confirm both discharge ports are correctly connected to their respective hydraulic circuits (double pumps).

4. Fluid Management

• High-quality anti-wear hydraulic oil is recommended; maintain fluid cleanliness at NAS 9 or higher—contamination is the leading cause of premature vane pump failure.

• T6 Series is compatible with mineral oils, water glycols, and phosphate esters.

• Regularly check oil temperature to ensure it does not exceed 80°C.

• The drain line must be routed separately back to the reservoir; back pressure must not exceed 0.3 MPa.

5. Scheduled Maintenance

• Replace hydraulic oil and filters every 2000 operating hours or annually.

• T6 Series features cartridge-type construction—cartridges can be replaced independently.

• Cartridge replacement can be completed in minutes without removing the entire pump.

• Mounting bolts and flange connections may loosen due to vibration; inspect and tighten periodically.

• If flow drops or pressure becomes unstable, first inspect cartridge wear—replacing the cartridge kit restores performance.
