Products from ZUWA Pumps

For over 70 years, ZUWA pumps has been a leading producer of high-quality, innovative pumping, fuelling, plant protection, charging and flushing station solutions for clients all over the world. Here at Ernest Electro, we offer an assortment of specialist ZUWA Pumps products, including flat suction systems, suction mats and related accessories.

Flat Suction Systems & Related Accessories

ZUWA Pumps & Flat Suction System provide instant help for the following:

  • Flooded basements, garages and platform roofs
  • Broken pipes and leakages
  • Discarding residue water from swimming pools
  • Simple and effective.
    • Flooded areas are drained to a close-to-dry state.

Suction Mats

Suction mats remove fluids within reach of the mats, nearly completely. Flow channels in the bottom side improve the suction effect, allowing the device to take even small amounts of liquid.

Being flexible and robust, suction mats work on slightly uneven ground as well.

Unlike submersible pumps and water vacuum cleaners the flat suction system is capable of completely pumping out the fluid and is applicable for large areas.

Depending on the dimensions of the flooded area even several mats can be connected in parallel to one pump.

Powerful Zuwa Pump

Sturdy and versatile, the flat suction system is provided with a heavy- duty ZUWA Pump.

The pump is suitable for slurping actions and tolerates a short dry-run. The flexible impeller wheel makes it possible for the system to transport soil and solid particles within the fluid.

Oil suction kits with oil resistant hoses, are especially for applications in flooded basements with damaged fuel oil tanks.

The pumps are not only suitable for water, but also for many different fluids like oil, heating oil, diesel and heat transfer fluid

Useful accessories


  • (suction-, delivery hose and extension). Special GEKA screw fitting for the suction line ensures hermetic sealing.



  • Dry run protection: sensor interrupts power supply when overheating.
  • Restart with reset button after eliminating the fault.


  • The perfect addition to the flat suction kit.
  • Flow rate: max. 150 L/min

Principles of operation

Flexible impeller pumps are displacement pumps. The rotor with flexible vanes is mounted concentrically in a circular housing which has a flattened area at one side. This provides the eccentric path for the impeller, thereby squeezing the flexible blades on this side.

1. Suction:

The impeller rotation and the straightening of the vanes upon leaving the cam creates a vacuum on the suction side drawing the fluid into the pump chamber.

2. Transfer:

The rotating impeller transfers the liquid from the inlet to the outlet port of the pump.

3. Press:

On the pressure side the impeller vanes are compressed, and the fluid is discharged constantly from the pump.

Pump types

UNISTAR (2000-A, B, 2001-A, B)

Multi-purpose pump designed for transferring clean or contaminated liquids. Not suitable for handling abrasive or corrosive fluids.

COMBISTAR (2000-A, B, 2001-A, B)

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.

NIROSTAR (2000-A, B, 2001-A, B)

A high-quality stainless-steel pump with numerous applications in industrial plants and production facilities, the appropriate choice for transferring corrosive fluids.

The advantages of an Impeller pump

Dry self-priming: The suction depth is max. 7 meters.

High capacity: Flow rate between 3 litres up to 730 litres per minute.

Reliable: Top quality materials guarantee for a long durability.       Versatile: Useful for many different fluids and applications.

Gentle: Fluids are transferred absolutely free of pulsation.              Easy maintaining: quickly and easily disassemble the pump. Low operation costs!

Sturdy: pumping fluids with even highly viscous liquids such (up to 20 000 mPAS), as well as liquids containing solids. Media temperature max. 90°C.

The Right Material of Impeller For All Applications

The NBR /Acrylnitril-Butadien-Kautschuk (Perbunan®, Buna-N®)

Perfect for water, antifreeze, heat transfer fluid, vegetable oil and grease high impact elasticity and good mechanical strength good for applications involving high pressures up to max 5 bar plastics.

They can also be used for mineral and vegetable oils, diesel fuel, heat transfer fluid and several chemicals. It is extremely tear resistant and provides good mechanical resistance (nichtbei abrasiven Medien) with a maximum fluid temperature 60°C

EPDM /Ethylen-Propylen-Dien-Kautschuk (Keltan®, Buna EP®)

They can be used for high temperatures, for acids and bases, offer high elasticity, and offer excellent mechanical stability

CR /Chloropren-Kautschuk (Neoprene®, Bayprene®)

Preferably used for applications in the food industry. Flame retardant, tearproof, durable.

FKM or FPM /Fluor-Kautschuk (Viton®, Fluorel®)

for oil, diesel, fuel oil, palm oil, soy bean oil and oil emulsive wood preservatives excellent chemical resistance, less mechanical resistance

 Accessory for Suction Kit TOP: Automatic Multi-Purpose Pump Control 230 V

  • Useful in various applications for pump control and signal equipment with power up to 1,1 KW
  • sensor switching the pump on and off automatically, depending on fluid level (dry run protection)
  • particularly suitable for low fluid levels, from appr. 1 mm
  • small and compact design, splash-proof
