BRIEF HISTORY - Independent and innovative family enterprise

Over the course of more than 50 years, as a globally focused, independent, family owned enterprise GEMÜ has established itself in all important industrial sectors thanks to its innovative products and customized solutions for process media control. Thanks to consistent innovation and emphasis on quality and customer focus, GEMÜ has developed into a world market leader in the area of valve designs for all main and auxiliary processes of the pharmaceutical and biotechnology industries as well as mining and other industrial markets. GEMÜ is a manufacturer of innovative and high quality valve technology, with world class facilities in Germany, Switzerland, China and Brazil and over 2000 employees worldwide. Most of GEMÜ´s solutions are available in metal or plastic materials. The complexity and compliance with customer requirements for modern plant engineering inspires us to continuously develop our products and we can boast many awards for innovation and design.

Reliable service in South Africa and the whole continent

After many years of being represented by a distributor, In 2008 Gemü Africa was established in Johannesburg. Currently with 11 employees, thanks to our well established warehouse, prompt and reliable service and delivery to our local customers in the Republic of South Africa, but also into many other countries on the African continent, the company has grown from strength to strength.

Coping with stringent requirements

The varied processes in industrial plants often have stringent requirements for the valve technology employed. High temperatures, high pressures and critical working media require very specific valve solutions and components. GEMÜ has been offering these solutions for decades, supporting our customers in fields such as chemistry, mining, pharma-food-biotech, energy, water treatment and all other applications of the general process industry.

Intelligent measurement and control technology

Beside the valve technology, GEMÜ also offers precisely tuned valve instrumentation, controllers, sensor systems, valve actuators and system solutions for process automation. GEMÜ provides the most varied designs to suit any automation concept, comprising not only simple switches but also intelligent designs equipped with time-saving automated initialization.

Mining, minerals and metal winning

One of GEMÜ's strengths as a valve manufacturer is that it offers customized process solutions which combine the valve with the actuator and sensor system as an integral unit, well adapted to the customers’ working conditions. Where solids and slurries are involved, mechanical wear (abrasion) and deposits (scaling) in the system are often a cause of failure. When hydro-metallurgical processes such as

GEMÜ valves have been devolved for aseptic and hygienic processes. They are used in the production of yogurt, sugar solution, fruit and smoked products, as well as the filling of bottles containing water, soft drinks and dairy products. The individual production processes are as varied as they are complex:  injection, peeling, heating,    boiling, smoking, cooling, filling, homogenisation, Mixing, separation, sterilisation, autoclaving, pasteurisation, cleaning (WIP/CIP/SIP), degassing and drying.  Across this spectrum, GEMÜ offers the right valves for the precise control of liquids, gases, smoke and steam.

Certified diaphragm sealGEMÜ is a member of the “European Hygienic Engineering & Design Group” (EHEDG). The GEMÜ seal system for diaphragm valves has been EHEDG-certified since June 20016. The diaphragm seal is at the heart of every valve. It hermetically separates the actuator from the body and enables optimal cleanability

The varied processes in industrial chemical plants have stringent requirements for the valve technology employed.  High temperatures, high pressures and critical working media require very specific valve solutions and components. Diaphragm valves, which are especially suitable for corrosive media, can be precisely adapted to the working media be means of various diaphragm materials. In addition, the diaphragm valves can be lined with high-tech plastics, for example PFA or PVDF.

This combines the resistance of plastics with the robustness of industrial valves. This flexibility regarding material selection ensures maximum process and plant reliability; thus providing optimum customized solutions for :Electroplating,Filtration,Neutralisation,Distillation,Biodiesel production,Paper manufacturer, Chromatography, Fertiliser production
