Chemvac Pumps are engineered for performance in the most challenging fluid transfer applications. Designed and manufactured in the UK, Chemvac has established itself as a specialist in robust liquid ring vacuum pump technology for use across chemical processing, oil and gas, marine, environmental, and general industrial sectors.
With a strong emphasis on quality, durability and system reliability, Chemvac Pumps are built to excel in harsh operating environments where efficient gas and vapour handling is critical. These pumps are ideally suited for evacuating sealed systems, recovering solvents, removing vapours, priming pipelines, and supporting vacuum-assisted processes.
At the core of every Chemvac system is liquid ring vacuum technology — a proven, low-maintenance design that uses a rotating impeller to create a consistent vacuum within a fluid-filled chamber. This allows Chemvac Pumps to operate smoothly without the friction or heat buildup associated with other vacuum pump types, making them perfect for continuous duty applications and ATEX-classified zones.
Chemvac Pumps are available in a wide range of configurations to suit the specific demands of your process. Units are offered in standard and customised layouts, with single and two-stage models available to accommodate different pressure and flow requirements. Pumps can be supplied as bare shaft units or as complete vacuum packages with motor, coupling, baseplate and control systems — all built to order for seamless integration.
One of the standout features of Chemvac Pumps is its flexibility in materials of construction. Depending on media compatibility, units can be manufactured from cast iron, stainless steel, bronze or specialised alloys. This allows for reliable operation with corrosive, contaminated or even solid-laden gases, all while extending service life and reducing system maintenance intervals.
Chemvac also supports a variety of industries with solutions tailored to their unique process needs. Whether it’s gas extraction in petrochemical facilities, vapour removal in food processing, or safe solvent recovery in pharmaceutical applications, Chemvac Pumps provides dependable vacuum performance backed by decades of expertise.
A key advantage of working with Chemvac is its in-house engineering capability. The company provides bespoke solutions based on customer requirements, offering full mechanical and electrical design support, CAD modelling, and compliance with global standards. This ensures every Chemvac Pump system is fit-for-purpose, efficient, and safe for operation in its intended environment.
In addition to new pump supply, Chemvac offers a comprehensive rebuild and refurbishment service. Used units can be restored to original specification with OEM parts and tested for full vacuum performance, extending equipment lifespan and delivering significant cost savings over replacement.
