Hydraulic Vane Pumps – Quiet, Smooth & Efficient Flow for Industrial Systems
Techknow Engineering Enterprise is a hydraulic vane pump supplier in India for machine builders, plant maintenance teams and system integrators. A hydraulic vane pump delivers a steady flow with very little pulsation and low operating noise, which makes it a preferred choice for indoor industrial machinery.
Our range includes fixed displacement vane pumps up to 210 bar with flow from 5 to 285 lpm, and variable displacement vane pumps up to 160 bar with flow from 37 to 270 lpm, depending on the series. Standardized mounting and connection dimensions make it easy to fit a new hydraulic vane pump to an existing power unit.
As an Authorized HYDAC Distributor and a supplier for leading pump brands, we help you select the right hydraulic vane pump for a new machine or source an equivalent replacement — backed by 14+ years of experience and pan-India delivery.
Fixed & Variable Displacement Vane Pumps
Vane pump solutions for low to medium pressure industrial and mobile hydraulic circuits.
Every hydraulic vane pump works on the same principle: a slotted rotor carries sliding vanes inside a cam ring, and the changing space between the vanes moves oil from the inlet to the outlet. How the cam ring is designed decides whether the pump has a fixed or adjustable output.
Which Hydraulic Vane Pump Suits Your Circuit?
A fixed displacement hydraulic vane pump delivers a constant volume per revolution. Many fixed designs are hydraulically balanced, with two inlet and two outlet zones opposite each other, so the radial loads on the shaft cancel out and bearing life improves.
Fixed vane pumps suit circuits with a steady flow demand, such as machine tool power packs and general industrial units.
A variable displacement hydraulic vane pump moves its cam ring to change eccentricity. When system pressure reaches the set value, delivery reduces to the flow actually needed, cutting power loss and heat while the circuit holds pressure.
This makes variable vane pumps a strong fit for presses, clamping circuits and injection moulding machines. For higher pressure duty, see our hydraulic piston pumps.
How a Hydraulic Vane Pump Works
As the shaft turns the rotor, centrifugal force and pressure oil push the vanes out against the inner surface of the cam ring. On the inlet side the chambers between the vanes grow and draw oil in; on the outlet side they shrink and push oil into the system.
Because each chamber fills and empties gradually, a hydraulic vane pump produces uniform discharge with negligible pulsation — which is why it runs quieter than many other pump types.
Selecting the Right Vane Pump
Start with the flow required and the motor speed to find the displacement. Then confirm the maximum working pressure, whether the circuit spends long periods holding pressure (a case for a variable pump), direction of rotation, mounting flange, shaft and ports.
Our team checks these points before quoting and can match the dimensions of your existing hydraulic vane pump so the replacement fits without changes to the power unit.

Fixed Displacement Vane Pumps
A fixed displacement hydraulic vane pump delivers the same volume of oil on every revolution, so flow depends only on drive speed. Balanced designs place the pumping zones opposite each other, cancelling radial shaft loads and supporting long bearing life.
These pumps are well suited to machine tools, power packs, presses and general industrial machinery where a steady flow and quiet running are needed.
Configurations & Specifications
- Working pressure: up to 210 bar (version specific)
- Flow rate: 5 – 285 lpm (version specific)
- Uniform discharge with negligible pulsation
- Standardized mounting and connection dimensions
Variable Displacement Vane Pumps
A variable displacement hydraulic vane pump adjusts the position of its cam ring. When the circuit reaches the set pressure, the ring moves towards the centre and delivery falls to the flow actually needed, so the pump does not waste power pushing excess oil over a relief valve.
This saves energy and limits heat in circuits that spend long periods holding pressure, such as presses, clamping systems and injection moulding machines.
Configurations & Specifications
- Working pressure: up to 160 bar (version specific)
- Flow rate: 37 – 270 lpm (version specific)
- Pressure and flow control to suit system requirements
- Lower power consumption and heat at standstill pressure
Combined Vane Pump Assemblies
A hydraulic vane pump can be combined with axial piston pumps, gear pumps and radial piston pumps on a common drive, so one motor can supply a high-flow, low-pressure circuit and a separate high-pressure circuit. This saves space on the power unit and simplifies the drive arrangement.
Tell us the flow and pressure needed in each circuit, and our team will propose a suitable pump combination. See also our hydraulic gear pumps and radial piston pumps.
Installation & Start-Up Tips
Fill the pump and suction line with clean oil before the first start, and check the direction of rotation — most vane pumps are designed for one rotation direction only. Keep suction lines short, generously sized and free of air leaks.
Vent air from the pressure line on first start-up so the vanes extend fully and the hydraulic vane pump primes quickly.
Maintenance & Service Life
Vanes and the cam ring are sensitive to dirty oil, so use suitable suction filters and hydraulic oil filters, and keep oil temperature in range with an oil cooling system where needed.
Rising noise, falling flow or difficulty holding pressure are early signs of wear. With a hydraulic vane pump supplier in India close at hand, a replacement can be sourced before a breakdown stops production.

FAQ'S
A hydraulic vane pump has a slotted rotor carrying sliding vanes inside a cam ring. As the rotor turns, the vanes move out against the ring and the chambers between them grow at the inlet, drawing oil in, then shrink towards the outlet, pushing oil into the circuit. The result is a steady, low-pulsation flow.
A fixed displacement vane pump delivers the same volume of oil every revolution. A variable displacement vane pump can change the eccentricity of its cam ring, so delivery reduces automatically as system pressure reaches the set value. This cuts wasted flow and heat in circuits that spend time holding pressure.
Fixed displacement vane pumps are available up to 210 bar with flow from 5 to 285 lpm, and variable displacement vane pumps up to 160 bar with flow from 37 to 270 lpm. Exact figures depend on the series and size, and our team confirms them for your selection.
A hydraulic vane pump is a good choice for low to medium pressure industrial circuits that need quiet running and smooth flow, such as machine tools, injection moulding machines, presses and power units. For very high pressure duty, a piston pump is usually the better option.
