We bring innovative hydraulics solutions to life with well designed hydraulic systems. Using tailored components, equipment, skills and know how, we design your hydraulic system to your exact requirements, aided by intuitive software MTPro. This means our system designs factor in hydraulic system components only from the world’s leading hydraulic manufacturers.
Various sectors across the board use Bosch Rexroth system designs for their hydraulic applications. A few examples include agriculture, manufacturing, automotive, pulp & paper, entertainment (see Ed Shereen show), power generation, aviation, construction and maritime, among others.
The primary components used when designing your basic hydraulic system are cylinders, motors, pumps, accumulators (reservoirs), valves, filters and actuators. We stock and use all components, including those not listed here, to ensure an optimised, highly functional hydraulic system that meets your expectations.
We supply bladder, piston & diaphragm hydraulic accumulators from Rexroth, HYDAC & Olaer. Choose the right accumulator for stable pressure.

VIEW PRODUCTIn the industrial sector, and others like maritime, aviation, aerospace, agricultural, military, construction, to name only few, hydraulic system engineering specialist companies are contracted to design hydraulic systems. This means the customer provides details about the industrial hydraulics application for which the hydraulic system is intended. Based on this, hydraulics engineers design a hydraulic system with specifications that will allow the system to reach that objective.
System design involves the selection of components and their sizing, establishing the operating pressure and flow rate of the system, and ensuring that component specifications meet the design objectives. Hydraulic tools are sometimes required when executing the system design.
The following hydraulic equipment is usually incorporated:
Hydraulics cylinders create mechanical force in a linear motion. They are used in mobile applications due to their ability to lift practically any load, and because of their huge push and pull capacity. Hydraulic cylinder repair is conducted by Hytec Engineering.
Most mobile machinery, like bull dozers excavators, loaders, mine dump trucks & graders, for example, rely on hydraulic cylinders. In the industrial sector, they are used in a hydraulic press machine, compactors, injection moulding, forging presses, etc.
The hydraulic reservoir, also commonly known as hydraulic accumulators, holds the hydraulic fluids – usually hydraulic oil – in hydraulic machines.
More than just a hydraulic tank, the accumulator in hydraulic systems transfers heat from the system, settles solid contaminants, preventing contamination of the fluid, and assists with the release of moisture and air from the fluid.
The task of the pump is to conduct mechanical energy into hydraulic energy by forcing the transmission medium (fluid) from the accumulator (reservoir) to the rest of the circuit. This is done by creating a vacuum at the pump inlet.
Hydraulic pumps all work on the same principle – the displacement of fluid volume against a resistant load or pressure. There are various types of pumps in hydraulics: fixed displacement pumps, variable displacement pumps, electric hydraulic pumps & manual hydraulic pumps – and portable hydraulic pumps are also sometimes used.
It is estimated that about one million particles measuring 1 μm (micron) or more enter a hydraulic system each minute. Hydraulic filters are therefore essential to continuously remove dirt and particles from the system, which may cause damage to your system components over time.
Selecting the most appropriate filter for the system and its application will contribute to longer component lifetime, reduced maintenance & downtime, and therefore costs.
To get power to your hydraulic pump and ensure that the pump’s mechanical elements work, an electric motor is required. Its sole function is to power the hydraulic pump because, If the motor stops running, the hydraulic system will shut down. Power is also achieved via a hydraulics motor.
When selecting the motor, the following factors must be taken into consideration: horsepower, rotational speed (rpm), voltage & phase, frame size & configuration, and the enclosure.
Poppet valves or spool valves are generally used in hydraulic systems to direct fluid flow as well as stop and start this flow, and to relieve disproportionate pressure from the system.
They are actuated by means of pneumatic, hydraulic, electrical, manual or mechanical means. These valve types can be pressure control valves (pressure relief valve, pressure reducing valve, sequence valve), flow control valves and directional control valves (check valve, spool-type valve, for e.g.).
Actuators convert hydraulic energy back into mechanical energy via a cylinder.
The cylinder converts hydraulic energy into linear motion, or a hydraulic motor can be used to convert hydraulic energy into rotary motion.
Hydrostatic drives are sometimes incorporated in closed-loop systems.
Bosch Rexroth Africa offers comprehensive hydraulics training, which incorporates hydraulic system design.
Our fully accredited hydraulic training courses are aimed at varying degrees of specialisation.
Wherever high power density is required or when load requirements change rapidly, a hydraulic system is required. Used across many industries, and for multiple applications, some application examples that use hydraulics systems are:
The 2 different types of hydraulic systems are open loop and closed loop hydraulic systems. Both systems use an extra pump known as a feed pump.
Open loop system:
Closed loop system:
