Product Portfolio
  • IMPELLER PUMPS

  • DRY SELF-PRIMING UNIVERSAL PUMP FOR MANY LIQUIDS

    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.

      • HVAC FILLING AND FLUSHING PUMPS

      • On account of their robust construction ZUWA filling and flushing stations for solar collectors, heat pumps and panel heatings are suitable for on site application. The Cleaning Mobile Center is also suitable for cooling lubricants in CNC-machining centers and heat transfer fluids in heat exchangers. The fully developed devices have been proved and tested for more than a decade in heating installation. For filling, flushing and venting we recommend our Flush Pro Mobile Center. We like emphasize the gentle cleaning when it comes to flushing a heating system. Instead of using a pulsating air-water-mix which strips larger particles away which may lead to blockage we suggest to use our device with soft water or a similar fluid to bind particles and collect them in the filter bag.

            FUNCTION

            The descaler circulates between heat transfers and the DESCAL MC. Thanks to that limescale comes loose and are collected in the container of the unit. This procedure is continued until the fluid is free of lime residuals, which is visible thanks to the transparent hoses and at the filter cup.

          • ADBLUE® PUMPS

                • Pumps for AdBlue® /DEF

                • Pumps, as well as tanks and tank facilities, for refilling or refueling commercial verhicles and passenger cars with AdBlue® (Diesel Exhaust Fluid, DEF, Urea, AUS-32).

                  PUMPS AND REFUELING SETS FOR ADBLUE ENSURE AN EASY AND SECURE REFUELING WITH UREA.

                  To reduce our impact on the environment with the emissions of diesel internal combustion engines, in some trucks and cars SCR catalytic converters are installed. In order to work properly these converters need diesel exhaust fluid, standardised as AUS-32 in ISO 22241. Here you will find all pumps, refueling sets, tanks and accessoires for DEF/AdBlue®.

                  Diesel engines emit, due to their design, NOx. Those nitrogen oxides are relevant for the ozone depletion. In order to reduce these climate damaging emissions, limits were enshrined in laws, which are known in the EU as EURO 5 and EURO 6. To reach the goal of not exceeding the emission limits most of the modern diesel engines are equipped with SCR catalytic converters. Prior to the SCR catalytic converter AUS-32 is injected which reacts with about 90% of the emitted NOx to harmless N2 (Nitrogen), water and little amounts of carbon dioxide.
