Executive Standard and Characteristics of Product

BQS (BQW) series flameproof submerged sand and sewage electric pumps for mines (hereinafter referred to as electric pumps)adopt the standard of MT/T67 1-2005 Flameproof Submerged Electric Pump for Coal Mine. The type of explosion proof construction of motor is flameproof marked as Exd I. Researched and developed by ourselves through sufficient market survey, this electric pump is a downdraft flameproof submerged sand and sewage electric pump for mines, which is driven by a late-model energy-saving dry-type three-phase asynchronous motor. Designed and manufactured in accordance with the requirements of explosion-proof standard, it offers strict flameproof measures in its motor and uses steel for motor enclosure, T he unit can not only pump out the surface and shallow water on working faces, but also work under water for long time. This electric pump takes the advantages of compact structure, easy movability, no need of priming water,double end-face mechanical seal, long durability, secured reliability,outstanding applicability, etc.
