Our centrifugal pumps: heavy-duty standardized pumps for chemicals made of plastic
We produce robust centrifugal pumps for industrial processes. Our work centers around the high demands made by plant engineering companies, particularly for handling aggressive substances. To meet these demands, our product series have a modular design and are divided into the classes STÜBBE CLASSIC, STÜBBE E-CLASS und STÜBBE X-CLASS (Heavy-Duty-centrifugal pumps).
All STÜBBE centrifugal pumps are made of highly resistant plastic, permit customization and set new standards of cost effectiveness and reliability!
Centrifugal pumps for extreme or simple processes
Our groundbreaking and extremely robust centrifugal pumps made of plastics redefine standards! The high-quality plastics (PP, PE, PFA and PVDF) we use to make our pumps guarantee reliable function, minimized wear, a long service life and safety – even under extreme temperatures or pressures.
Our modular centrifugal pump design reflects the consistent implementation of our quality standards. The material used offers a plethora of advantages such as electrical insulation, corrosion resistance, durability, light weight, low friction, environmental sustainability, versatility, low maintenance requirements and cost effectiveness.
Centrifugal pumps for any substance
Handling aggressive, corrosive or sensitive substances in industrial applications is a highly complex and challenging task. We have adapted our centrifugal pumps specifically to this challenge. Their modular design includes horizontal or vertical installation, pumps with mechanical seals (single- and double-acting), with magnetic couplings and high drive ratings, flow rates / pumping heads and a variety of nominal diameters.
We have the right centrifugal pump for any industrial application. Give our pump finder a try!
We have defined over 1600 aggressive substances that you can find in our extensive chemical resistance list (PDF available for download).
