Rotary Lobe Pumps

With our diverse standard and high performance pumps we are able to serve all your needs and response to any challenge. Our positive displacement rotary lobe pumps are robust, self-priming and have running dry capability. Our products porfolio offer rotary lob pumps for most applications. We offer explosion proof and seal-less pumps for the petrochemical industry, pumps with CIP option (cleaning in place), pumps with minimal surface roughness for the pharmaceutical and food industry and high pressure pumps for dynamic applications etc.

Our pumps are operational with nearly all liquids in the viscosity range between 1 and 1.400.000 mPa.s (higher viscosity on request). Rotary lobe pumps are suitable for middle to high viscosity liquids, liquids containing soft or abrasive particles as well as for dirty or polluted liquids.

We choose the pump materials carefully depending on specific requirements and objectives of your application.

On demand, we can provide external gear pumps which API, ATEX, TR-CU 10, TR-CU 12 and TA Luft compliant.
