VT67DDCS
- Mounting Flange: SAE C 6 bolts, J744 standard.
- Volumetric Displacement: Ranges from 10.8 cm³/rev (0.66 in³/rev) to 157.9 cm³/rev (9.64 in³/rev).
- Shaft Types: Keyed and splined options available, including SAE C and non-SAE configurations.
- Seal Class: Options for mineral oil (S1), fire-resistant fluids (S4), and mineral oil with fire resistance (S5).
- Direction of Rotation: Clockwise (R) and counter-clockwise (L).
- Pressure Ratings: Maximum pressures range from 140 bar (2000 psi) to 275 bar (4000 psi) depending on the model.
- RPM Limits: Maximum RPM varies by model, with some models reaching up to 2500 RPM.
- Internal Leakage: Not recommended to operate at 275 bar and 1500 RPM if internal leakage exceeds 50% of theoretical flow.
- Noise Levels: Provided for triple pump configurations under specific discharge conditions.
- Power Loss: Total hydromechanical power loss is calculated as the sum of each section's loss at its operating conditions.
- Permissible Loads: Maximum axial load is 1200 N (270 lbs).
- Ensure proper selection of seal class based on fluid type.
- Adhere to specified pressure and RPM limits to avoid excessive internal leakage and ensure optimal performance.
- Regularly monitor noise levels and power loss to maintain efficient operation.

HIGH PERFORMANCE VANE PUMP VT67DDCS INTERNAL LEAKAGE ( TYPICAL) NOISE LEVEL ( TYPICAL) Do not operate pump for more than 5 seconds at any speed or viscosity if internal leakage is more than 50 of theoretical flow. Total leakage is the sum of each section loss at its operating Triple pump noise level is given with each section discharging at the pressure noted on the curve. HYDROMECHANICAL POWER LOSS (TYPICAL) PERMISSIBLE RADIAL LOAD Maximum permissible axial load Fa = 1200 N (270 Lbs) Total hydromechanical power loss is the sum of each section at its operating conditions.
