Zuwa Zumpe, Flexible Impeller Pumps, Motor Driven

Featuring a Stainless Steel impeller case, and Stainless Steel end closure, these pumps are designed for liquids which are not chemically agressive to Stainless Steel, and are mildly abrasive, the Stainless Steel impeller case preventing wear of the impeller chamber.

VERSIONS WITH EPDM OR NEOPRENE IMPELLERS ARE ALSO SUITABLE FOR FOODSTUFFS AND F.D.A. COMPLIANT CERTIFICATES ARE PROVIDED WITH THIS MODEL.

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 impellor 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 a variety of voltages including 230v, 12vDC, and 24vDC

STANDARD MODEL IS FITTED WITH A UNI-DIRECTIONAL MOTOR AND 1/0 ROCKER SWITCH, THIS MEANS IT CAN ONLY PUMP IN ONE DIRECTION. 230vAC PUMPS CAN BE SUPPLIED WITH A BI-DIRECTIONAL MOTOR AND 1/0/1 ROTARY SWITCH, THIS ENABLES THE PUMP TO PUMP IN BOTH DIRECTIONS, HOWEVER, THIS OPTION MUST BE SELECTED AT TIME OF PURCHASE, IT CANNOT BE FITTED LATER AS IT REQUIRES A DIFFERENT MOTOR TO BE USED DURING MANUFACTURE. SELECT OPTION "Bi-Directional Switch" FROM THE OPTIONS LISTED BELOW, AS WELL AS THE PUMP YOU REQUIRE.

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*
