FOR A WIDE VARIETY OF APPLICATIONS IN THE CHEMICAL SECTOR
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.
REGULATE YOUR ZUWA FLEXIBLE IMPELLER PUMPS BY USING YOUR SMARTPHONE
The efficiency of machinery used is an important factor for plant operators, as increasing operating costs have become a topic of focus. By using a frequency inverter, the motor speed is continuously adjustable to allow the regulation of capacity during the filling and dosing process. The adjustment can be made with the keypad of the frequency inverter, via software with a LAN connection, or with an app using the Bluetooth connection of a smartphone or tablet.
MORE POWER, GREATER ADAPTABILITY, LESS DOWNTIME
The plus model NIROSTAR 2000-C flexible impeller pump is particularly distinguished by the fact that the pump can be opened without any tools. Not only does this shorten cleaning time for the pump, but also simplifies changing out the impeller. The new design offers the possibility to rotate the pump head in 45 increments, thereby allowing easy adaptation for difficult installation requirements. Capacity range has been increased, as the plus model NIROSTAR 2000-C achieves a delivery rate of 120 l/min over the standard versions 90 l min. The ZUWA NIROSTAR 2000-C plus is available with 230 V and 400V drive.
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.

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.
We offer oil pumps for many different viscosities, kinds of oil and with several drives.
There are many different kinds of oil, since oil only describes the viscosity of a liquid and its characteristics of being hydrophobic (immiscible with water) and lipophilic (miscible with other oils). Generally speaking there are mineral oils, organic oils and synthetic oils. They are used for food (oil from pressed oilives for example), fuel (e.g., heating oil), lubrication (e.g., transmission or engine/motor oil), manufacturing of plastic products, paint or other materials or medical purposes.
Irrigation, flushing, plant protection
PTO Pumps from ZUWA are ideal to convey water and pesticides. They are self-priming and sturdy.
The PTO 20 and 25 are fully equipped. For PTO 300 accessories are to be ordered separately.
The DESCAL Mobile Center is a decalcifying unit for professional use to flush warm water tanks and heat exchangers with descaler. In several industrial processes diverse fluids like process water, glycolic coolant, cooling lubricants and other fluids are used.
Different media are used in industrial applications. Among them are process water, glycol based coolants, and cooling lubricants.
The effectiveness of the process can deteriorate over time due to aging of the machinery, or impurities in the media that accelerate the wear of components. Foreign debris, sediment, and corrosion can impede the process, and cause unexpected downtime. Filtering the media, flushing and cleaning of the respective equipment on a regular basis is important to avoid such trouble.
