Zuwa Zumpe, Flexible Impeller Pumps, Motor Driven, ATEX Approved
2021 - Zuwa have imposed a Minimum Order Value, so we are now unable to supply Zuwa products below the combined value of, currently, 650.00 GBP.
With Cat 2 ATEX Approved motor, for use in Zone 1 Explosive Atmospheres. Please note it is only the motor which is ATEX approved, not the pump itself, therefore they should only be used for pumping of liquids with a flashpoint of 55°+
Featuring an Aluminium impeller case, and Aluminium end closure, these pumps are designed for liquids which are not chemically agressive to Aluminium, and are non-abrasive. Also available with Stainless Steel impellor case with Aluminium end closure for liquids that are mildly abrasive, or a fully Stainless impeller housing for liquids corrosive to Aluminium, and Foodstuffs
These Top Quality, extremely durable Flexible-Impeller pumps are excellent for pumping viscous liquids which have a particulate content, for example Waste Engine Oil, Waste Cutting Oil, Waste Lubricating Oil, Waste Vegetable Oil, and Waste Glycerine (Subject to selection of the correct impeller material for chemical compatibility). The motors supplied with these pumps are Continuous Duty rated, and will go on and on
The Flexible Impeller itself is made from either NBR, Viton, Neoprene, or EPDM, Viton being a rubber which is chemically resistant to liquids of many types including the above mentioned liquids. The impeller blades flex as particle matter passes between them and the pump housing, this prevents damage to the impeller and promotes long life of the pump. NBR is suitable for conventional diesel and motor oils only
These pumps are especially popular with producers of Bio Fuels, who require pumps which can suck up Waste Oil from a storage bin / tank and dispense it into a drum or other vessel for removal from site
Available in 230vAC 50Hz only

Shown Below; Optional Pump Carrier;
A pump carrier serves to protect the motor from ingress of liquids that may be corrosive to the pump shaft seal, if the seal is compromised, the liquid will leak out of the pump, and out through the carrier into a drip tray / absorption mat, instead of entering the motor winding's, destroying the motor. The pump carrier does not enable the pump to be run at higher temperatures, becauSe the temperature is limited to 90°c by the rubber impeller inside it.
*PUMP CARRIER MUST BE ORDERED WITH THE PUMP/S, IT CANNOT BE FITTED IN RETROSPECT*
