Tsurumi – BX submersible pump Explosion proof

The BX-series is the explosion–proof type of the B-series and is available for operating in an area in which an explosive atmosphere occurs occasionally. The pump conforms to the relevant EU directives and is certified by ATEX II 2 G Ex d IIB T4 standard.

Application

Transferring sewage and wastewater to wastewater treatment plant
Dewatering wastewater from industrial plant (e.g. petrochemical plant, etc)
Pumping wastewater from collection sump where explosive atmosphere is likely to present

Impeller

Flame proof according to ATEX An impeller having a wide channel extending from inlet to exit,

which prevents internal clogging by

solids sucked in via the inlet.
