Repair Don’t Replace
Our Process
Contact us to arrange a quote when your plant and machinery is down, you need a solution fast. We can provide rapid pick up, evaluation, diagnosis, and accurate quote to get you up and running in the quickest possible time. Our professional team are skilled in all aspects of hydraulic repair and rebuilding and pride ourselves on helping our clients minimise their downtime and any interruption to their operations.
All units received into the workshop are cleaned before being stripped. One of our skilled engineers will then carefully dismantle and inspect your unit free of charge.
Our inspection is followed up with comprehensive findings report and competitive no obligation quote for any required work.
As part of the repair process, all damaged and worn parts will be replaced, along with all bearings and seals. Mating faces will be reworked, and the unit will be thoroughly cleaned before being rebuilt back to OEM specifications. As standard, any unit received with fittings will be returned to customers cleaned and all O-rings will be replaced.
The unit will then be tested on our custom-built test rig. Our test rig has been designed specifically for purpose and has the flexibility to test the majority of products available.
Why Choose to Repair Your Pump?
- Cost Savings: Repair is often significantly cheaper than purchasing new units, without compromising on performance.
- Faster Turnaround Times: With a vast network of spare parts suppliers, we can typically repair your pump faster than the delivery of a new unit. Combined with an efficient repair process and rapid response times, this ensures your machines have less downtime, thus avoiding costly production losses.
- Expertise: Our technical expertise enables us to identify and solve problems not always addressed by new purchases. After an investigation, for example, we might determine that the fault lies elsewhere in your system, preventing the needless installation of a new pump.
- New Lease Of Life: Even pumps that are obsolete, and no longer supported by the main dealer, can be repaired.
- Environmental Impact: By opting for repair, you contribute to reducing waste and the demand for new raw materials.
All our work comes with a 12-month warranty
Frequently Asked Questions
A hydraulic pump is a mechanical device that generates flow with enough power to overcome pressure induced by the load at the pump outlet. It’s a fundamental component in a hydraulic system, which uses fluid to transmit power from one area to another.
Its primary function is to convert mechanical energy into hydraulic energy. This is done by producing flow or oil movement, which is then pressurised according to the resistance present. The power the hydraulic pump provides is equal to the flow x pressure.
A hydraulic pump has various applications and is widely used in many industries such as construction, manufacturing, and automotive.
There are several types of hydraulic pumps including gear pumps, piston pumps, and vane pumps, each with its own mechanism and applications. The choice of hydraulic pump depends on the specific requirements of the system such as fluid type, flow rate, and pressure range.
A hydraulic pump and motor are two key components in a hydraulic system, and while they operate based on similar principles, they have distinct functions.
- Hydraulic Pump: The primary function of a hydraulic pump is to convert mechanical energy (like from an electric motor or engine) into hydraulic energy by generating flow. This means it takes in a volume of fluid from a reservoir at low pressure and sends it to the hydraulic system at a higher pressure. The high-pressure fluid can then be used to perform work in the system, like moving an actuator.
- Hydraulic Motor: On the other hand, a hydraulic motor is a type of actuator that converts hydraulic energy back into mechanical energy. It takes in high-pressure fluid from the system, which causes it to rotate, and this rotational movement can be used to perform work, like driving wheels or a conveyor belt.
A hydraulic pump and motor differ due to pumps supplying the hydraulic fluid under pressure and hydraulic motors use that fluid to create motion. Although they are built similarly and operate based on similar principles, their roles in a hydraulic system are opposite to each other. Nonetheless, CJ Plant provides excellent service on both hydraulic pump and motor repair.
There are several signs that a pump may be in need of a hydraulic repairs service. Hydraulic systems often have similar symptoms of faultiness, but nonetheless, hydraulic components often show the following signs of faultiness:
- Excessive Noise
- Decreased Hydraulic Power
- Overheating
- Cavitation
- External Fluids Leakage
- Poor or Erratic Performance
Again, these faults could be from any of the hydraulic applications, whether it be pumps, motors or the cylinder. Nonetheless, the best course of action every time is to have them repaired. This is because over time, there will be high amounts of wear and tear that will damage the entire system eventually.
Sometimes, contaminants such as dirt will build up within the pump’s reservoir. With regular cleaning, you can prevent this from reaching unmanageable levels. Without routine maintenance, however, this will disrupt the airflow of the machine and lower the machine’s ability to cool down.
This essentially turns your pump into an oven and will begin to rapidly decrease its overall practical life. Before anything else, it’s almost certain that the water temperature itself won’t be what kills the machine, but it will cause a major fault that will mandate a repair.
