Our high-performance pumps and agitators operate reliably even under demanding process conditions. They handle media ranging from low to high viscosity and are suitable for both low- and high-pressure applications. We offer centrifugal and positive displacement pumps that are proven solutions for fluids with solids content and even under extremely low NPSH conditions. Our hygienic pumps are successfully used in the food and pharmaceutical industries – wherever maximum standards in cleanliness, product integrity, and cleanability are required. Our comprehensive agitator portfolio complements the range, offering solutions for a wide variety of mixing and processing tasks.

The Quattroflow four-piston diaphragm pump enables the gentle pumping of sensitive media with low pulsation.

Our partners are internationally leading manufacturers of ball valves for hydrogen H2 and geothermal energy up to 1000 bar

Tough on duty, gentle on the medium. Rotary piston pumps are reliable positive displacement pumps characterized by their versatile industrial applications. They pump low-viscosity to medium-viscosity media with low pulsation. Their special design guarantees low shear and good suction capacity of the pumped medium.

Flexibility and efficiency. Rotary lobe pumps are robust and compact positive displacement pumps used in almost all industrial sectors. They pump a variety of media, including low-shear and low-pulsation materials, as well as abrasive, viscous, sticky, particle- and gas-laden materials. These pumps are particularly well-suited for pumping media ranging from thin to puncture-resistant. The pump can operate in both directions of rotation and can be easily equipped with various drive systems.

Pathogens don't stand a chance! To meet the stringent requirements of the foodstuffs, pharmaceuticals, cosmetics or chemicals industry, companies working in this sector need equipment such as the RotoTwin® screw pump, which was designed to meet the strict EHEDG hygiene requirements. Two intermeshing rotating feed screws reliably deliver products with high to low viscosity as well as gaseous or volatile products. Due to the axial movement and low acceleration, the RotoTwin® never fails to impress with its powerful suction capability and gentle product delivery. The contactless operation of the feed screws makes the pump safe even when running dry. Even larger air bubbles in the pipe will not harm the pump. The pump’s ability to reverse the direction of rotation enables the medium to be pumped in both directions, making it possible to use the pump for filling or emptying
