Vickers style hydraulic vane motors: direct replacements for industrial applications
Hydraulic vane motors for replacing existing equipment
Vickers style hydraulic vane motors are a solution for replacing hydraulic motors installed on industrial machinery that needs rotary motion, steady torque and reliable operation. These motors convert hydraulic energy into mechanical energy to drive mechanisms, production equipment and hydraulic transmission systems.
Technical Union offers Vickers style replacement hydraulic vane motors in the 25M, 35M, 45M and 50M series. They are intended for applications that need to replace an existing motor with a unit compatible with the design and requirements of the original hydraulic system.
If you need a hydraulic vane motor for machinery maintenance, repair or rebuild, you can review the available options and request a quotation from Technical Union.
Replacing Vickers style hydraulic motors
When a hydraulic motor shows wear, loss of performance or mechanical failure, finding a suitable replacement is essential to reduce machine downtime.
Vickers style vane motors are aimed at replacement applications where the existing equipment configuration needs to be kept. The correct selection depends on the series, displacement, required torque, operating pressure, RPM, direction of rotation, shaft and mounting configuration.
Available series include:
- 25M: motors for applications that require displacements of 2.68, 3.52 and 4.19 in³/rev.
- 35M: options with displacements of 5.10, 6.12 and 7.44 in³/rev.
- 45M: options with displacements of 8.42, 9.96 and 11.79 in³/rev.
- 50M: options with displacements of 14.11, 16.36 and 19.35 in³/rev.
These designations identify the motor family and guide the replacement selection. To confirm compatibility, compare the full model code and the specifications of the original unit.
Industrial applications of hydraulic vane motors
Hydraulic vane motors are used in systems that need hydraulic rotary power to drive machine mechanisms and components.
Potential applications include:
- Hydraulic drives for industrial conveyors.
- Transmission and drive systems for production machinery.
- Auxiliary equipment on plastic injection molding machines.
- Rotary mechanisms on manufacturing and processing lines.
- Hydraulic systems on material-handling machinery.
- Auxiliary drives on specialized industrial equipment.
- Machinery that needs to control rotational speed and torque through a hydraulic circuit.
The right application depends on the motor capacity, the hydraulic circuit, the available pressure, the supplied flow and the working conditions.
Industries that use hydraulic vane motors
Vickers style hydraulic vane motors can be relevant for companies that operate or maintain machinery with hydraulic drives, including:
Plastics: injection molding machines and auxiliary equipment that use hydraulic motors to drive machine mechanisms.
Industrial manufacturing: production equipment, processing machinery and rotary drive systems.
Material handling: conveyors and other industrial equipment with hydraulic drives.
Industrial maintenance and repair: hydraulic shops, machinery rebuild companies and maintenance departments that need to replace installed motors.
Hydraulic system integration: machinery manufacturers and companies that maintain hydraulic power units and drive circuits.
Series 25M, 35M, 45M and 50M: displacement and torque
Selecting a hydraulic motor should consider both the displacement and the torque the application needs.
Displacements available in these series run from 2.68 to 19.35 in³ per revolution. The maximum torque shown for the configurations on this page varies with size and displacement:
- 25M series: indicated maximum torque from 1,025 to 1,600 lb·in.
- 35M series: indicated maximum torque from 1,960 to 2,840 lb·in.
- 45M series: indicated maximum torque from 3,200 to 4,450 lb·in.
- 50M series: indicated maximum torque from 5,450 to 7,470 lb·in.
Pressure and speed limits vary by series and service conditions. Continuous and intermittent operation do not necessarily share the same limits. Check the specifications for each configuration before selecting a motor.
How to identify the replacement hydraulic motor
To find the right replacement for a Vickers style vane motor, we recommend providing as much of the following information as possible:
- Model number or the full code from the identification plate.
- Motor series: 25M, 35M, 45M or 50M.
- Displacement and required torque.
- Operating pressure and speed in RPM.
- Required direction of rotation.
- Shaft type, mounting flange and hydraulic connections.
- Make and model of the machine where it is installed.
A match on series alone does not mean two motors are interchangeable. Dimensions, mechanical configuration and hydraulic requirements still have to be checked.
Request a quotation for Vickers style hydraulic motors
Technical Union connects industrial buyers with hydraulic component solutions for maintenance, repair and replacement of existing equipment.
If you are looking for a Vickers style hydraulic vane motor in the 25M, 35M, 45M or 50M series, send the original motor model number, the specifications you have and the machine application. Our team can help evaluate the required configuration and review replacement options.
