The family run enterprise ZUWA-Zumpe GmbH has been manufacturing high quality pumps and innovative pump systems for more than 70 years. The ample experience in designing and producing high end products enables us to offer a wide range of different devices.
The entire product range consisting of pumps, fuelling stations, plant protection systems as well as charging and flushing stations is in high demand all over the world. ZUWA is working in accordance with the ISO 9001:2015 quality management system, regularly controlled by TÜV SÜD. Process safety and constant quality is guaranteed.
The close contact with our customers provides us with proposals and impulses to improve and further develop our products. in house production and shop floor enable us to meet customer specific requirements, manufacture custom made products and complete repair jobs. Competent contact persons and lean management make for quick and reliable service.
Impeller pumps by ZUWA are especially easy to maintain and cheap to run. Thanks to the flexible impeller the pumps are capable to move solid content or convey highly viscous fluids.
The running wheels (impellers) in our impeller pumps are available in different, always flexible materials to meet the requirements of many fluids. The impellers are not arranged centered in the elliptical housing. Due to the rotation of the impeller and therefore the bending of the impeller's blades a vacuum is created which sucks in the liquid. Because our impeller pumps are self-lubricating, only a rather short dry run is possible. After utilisation a longer dry-run is possible, but not recommendable.
ZUWA impeller pumps are available in several sizes with several drives and are made drom stainless steel, aluminum or plastic. We provide impellers made from NBR, EPDM, CR, FKM, FPM and TPU.
Our impeller pumps can be used with different drives: electric motors, air motors, belt drive, hydraulic motors, with a power drill or a cordless drill with an adapter.
The flexible impeller turns within an eccentrically formed casing creating a suction via the flexing of the impeller blades, which draws the fluid into the pump casing. The medium itself acts as a lubricant between the blades and the casing, therefore minimizing friction and allowing smooth fluid transfer. In order to avoid possible damages to the pump it is recommended to install dry run protection to each flexible impeller pump by ZUWA.
A multi-purpose pump designed for transferring clean or contaminated liquids. Not suitable for handling abrasive or corrosive fluids.
ZUWA-Impeller pumps are easy and inexpensive to maintain. They are insensitive to solid content in the fluid due to the flexible impellers and can even promote high-viscosity fluids.
The pump series UNISTAR is made of aluminum and suitable for all non-abrasive and non-corrosive media. Below for liquids like:
The maximum delivery rate is between 15 and 90 liters / min.
This pump is particularly suitable for all fluids containing abrasives. It is an economic alternative to the NIROSTAR series for transferring abrasive or slightly corrosive fluids.
Our COMBISTAR consists of a material mix. All wetted parts are made of stainless steel. The pump body is made of aluminum. Therefore suitable for all liquids which also contain abrasives.
This type of pump offers a low-cost alternative to the NIROSTAR series to promote abrasive or slightly corrosive media such as contaminated fluids and debris.
A high quality stainless steel pump with numerous applications in industrial plants and production facilities, the appropriate choice for transferring corrosive fluids.
As a manufacturer of impeller pumps, we pay special attention to quality. They are particularly easy to maintain and inexpensive to maintain. They are due to the flexible wheels insensitive to solids in the medium and can promote even highly viscous liquids.
The synthetic impeller pump is for a wide variety of applications in the chemical sector. Perfect for fluids with various viscosities plus agressive acids, bases and solvents.
Perfect for fluids with various viscosities plus agressive acids, bases and solvents.
Using top quality seals and Impellers made of VITON provide excellent operation safety. Various motors (220, 400 V; 1.400, 2.800 U/min; 50, 60 Hz). “Star knobs” make for quick and simple replacement of the Impeller.
The Ceramic sleeve to protect the motor shaft comes as standard equipment. Using a frequency converter permits to adjust the pump speed or rotation direction.
