Tsurumi KRDX-33.7 Explosion-proof Slurry Pump

SKU:
KRDX33.7

PRODUCT INFORMATION

The KRDX-series pumps are submersible slurry pumps equipped with agitators recognized by both IECEx and ATEX. With the impeller, suction plate, and agitator made of high-chromium cast iron and the pump casing and motor frame made of ductile cast iron, KRDX-series pumps are excellent in terms of wear resistance, and thus suited for drainage of mud-water, sediment-containing water, and various kinds of liquid slurry.

Tsurumi’s prime design objective is to ensure continuous duty over a long time on the basis of reliability that promises stable operation even under harsh operating environments as well as outstanding durability and maintainability. Making the most of its longstanding experience and know-how, Tsurumi also carries products that withstand particularly severe applications such as drainage of high-temperature liquids and corrosive liquids as well as pumps built to 1000-V-rating specifications.

Please Note: Specification's are a guild only and may change without notice.

*1 Male threaded coupling available upon request
*2 For orders from areas other than Europe and South Africa, it is necessary to check the voltage, the cable specification, the specification of the diode
and the designation of its orientation, and the circuit diagram.
*3 The pump is equipped with an explosion-proof motor, but never operate the pump below the continuous running water level (C.W.L.).
Doing so may cause sparks to occur, which in turn may lead to an explosion.
*4 Weights excluding cable
