Veljan VT* series Vane Pumps are high-performance fixed displacement pin vane design available in Single, Double, Triple and Drive Train configurations. These can be driven by fixed or variable speed prime movers.
Long Service Life Features
Veljan VT* series Vane Pumps are high-performance fixed displacement pin vane design available in Single, Double, Triple and Drive Train configurations. These can be driven by fixed or variable speed prime movers. Single Pump Double Pump Triple Pump Due to hydraulic pressure compensation and a rigid bearing arrangement, an outstanding operational life can be achieved by using Veljan Vane Pumps.
Large Power Range
Veljan Vane Pumps offer a comprehensive range of Single, Double and Triple Vane Pumps in a large variety of flow capacities. Based on the individual maximum operating pressures, the corresponding power range varies. All pumps are light weight and compact in design, resulting in an exceptional power-to-weight ratio.
Low Noise Level
Reduced noise levels are well within the acceptable limits of the industry. Large size cartridge displacements optimize operation for the lowest noise level in the smallest envelope. Uni-directional cartridge pumps are more quiet in operation in comparison to bi-directional cartridge pumps.
Excellent cold start capability and superior resistance to seizure make Veljan Vane Pumps highly reliable and efficient.
High volumetric efficiency (typically 94%) reduces heat generation, allows low speeds at full pressure and high mechanical efficiency (typically 94%) reduces energy consumption. Better efficiency under load increases productivity
Low ripple pressure reduces piping noise and increases life of other components in the circuit.
High resistance to particle contamination because of double lip vane increases pump life.
Large variety of options (cam displacement, shaft, portpositions) allows customized installation.
Low speed, low pressure, high viscosity allows application in cold environments with minimum energy consumption and without risk of seizure.
Camrings are dry lubricant coated and suitable for severe duty applications. This special coating helps in lubrication of the cam surface, especially during cold starts as also while in operation. Additionally this reduces wear which in turn extends life of the pump.
Side feed holes reduce internal leakage, help balance internal pressures, improve lubrication and provide a cooling effect.
Vane loading pins load the vane against the cam ring. Loading is in direct proportion to pump discharge pressure, which minimizes wear and prevents overshoot pressure and vane blow-off.
The shaft option T (SAE J718c), allows direct drive (at 540 or 1000 RPM) on tractors. The double shaft seal (VT6* P) version and drain hole allow direct mounting onto gear boxes.
