We design, assemble and test high pressure pump packages, vacuum systems, compressors, and many other flow solutions.

Our engineers specialise in packages for hazardous areas and we relish the challenges of packaged equipment weight and size reduction, and the pumped medium specified by our customers. Bespoke pump and unit designs make up much of our workload and our engineering knowledge and experience enables us to provide high pressure flow solutions for some of the most extreme operating environments on earth.

Standard pump products for both safe and hazardous areas are accompanied by a range of accessories. All are supported by our life cycle services team who provide spares, commissioning and service support worldwide.

Our success over four decades is founded on uncompromising quality and the incorporation of the very latest technologies into our products.
