Our main areas of service are listed below:

Hydraulic pumps

Hydraulic & Pneumatic Cylinders


We have a standard range of Hydraulic cylinders, some of which can viewed by hydraulics following the above link, but if you have a one off or require a custom built cylinder please contact us and we will be happy to help. We can also manufacture cylinders for offshore and sub sea applications to DNV or equivalent standard.

Service Centre

We can repair all your pneumatic and hydraulic rams from small workshop rams such as the Enerpac range to enormous cylinders used in steel foundries.

A ram can come in many different types such as, double acting, single acting, telescopic, displacement, spring return and hollow, our workshop is equipped to handle them all.

Manufacturer of hydraulic cartridge & flow control valves, solenoid valves & Custom Manifold Blocks. Free design service

If, like us, you have pallet racking in your warehouse for the most efficient way to store your products, you need to make sure that you racking is safe for your workers, and for any visitors including members of the public and suppliers.

Cavity Plugs

Cavity plugs allow for the removal of cartridge valves from a circuit while still maintaining the integrity of the hydraulic system. This is often desirable when a system needs flushing following repairs, component replacements or to change an operational function within the circuit. Cavity plugs are available in all frame sizes and are offered in a variety of styles: 2 port cavities, 3 port cavities, 4 port cavities (external locating shoulder), 4 port cavities (internal locating shoulder) and 6 port cavities.

It is paramount when car owners come to purchase car warranty that they use a firm that has no mileage restrictions, or limit to the number of repairs you can have, and that all repairs can be carried out at any VAT registered garage or dealer of their own choice.

In the realm of fluid power systems, Hydraulic and Pneumatic Cylinders stand as integral components, playing a pivotal role in translating fluid pressure into linear mechanical motion. This engineering marvel finds widespread application across various industries due to its versatility, precision, and reliability.

Design and Functionality

Hydraulic Cylinders harness the power of hydraulic fluids to generate force and motion. Typically consisting of a cylinder barrel, piston, and hydraulic fluid, these cylinders leverage the principles of Pascal's Law to exert force in a linear direction. The seamless integration of high-grade materials, precision machining, and advanced sealing technologies ensures optimal performance, durability, and minimal maintenance requirements.

Pneumatic Cylinders

On the other hand, rely on compressed air to drive mechanical motion. Designed with a similar structure, these cylinders are adept at delivering rapid and efficient linear movement. Their lightweight construction and simplicity make them suitable for applications where space constraints and swift response times are critical.


The applications of Hydraulic and Pneumatic Cylinders span a diverse range of industries. In manufacturing, hydraulic cylinders are frequently employed in heavy-duty machinery, such as presses, injection molding machines, and metal forming equipment. Pneumatic cylinders find their niche in tasks demanding rapid and precise movements, such as robotics, packaging machinery, and automotive assembly lines.

Engineering Precision

Engineering excellence is at the core of Hydraulic and Pneumatic Cylinder design. Rigorous adherence to industry standards, coupled with continuous innovation, ensures these components meet the demanding requirements of modern machinery. Engineers meticulously calculate load capacities, select appropriate materials, and optimize sealing mechanisms to guarantee optimal performance under various operating conditions.

Materials and Technology

Hydraulic and Pneumatic Cylinder manufacturing involves the use of high-strength materials, such as alloy steels and aluminum alloys, to withstand the forces exerted during operation. Cutting-edge technologies, including computer-aided design (CAD) and finite element analysis (FEA), enable engineers to simulate and refine cylinder designs for enhanced performance and longevity.

Environmental Considerations

Engineers in this field recognize the importance of sustainability. Efforts are directed towards developing cylinders with reduced environmental impact, focusing on energy efficiency, recyclability, and the use of eco-friendly hydraulic fluids.
