Explosive liquid pump BZWHB200-280-20/4, 37kW, 1450, Ex, stainless steel self-priming

Self-priming stainless steel pump BZWHB. The impeller is a closed type with two blades, with wide channels for clean and dirty liquids with impurities. The pumping part is connected to the motor via a coupling, which guarantees quick recovery of the pump in case of electric drive failures. High electrical and hydraulic efficiency. High self-priming rate without the use of a check valve (4.5 - 6.0 m.v.s.). The self-priming capability is realised due to the presence of a pre-filling chamber in the pump casing. The pumps of this model are suitable for the chemical, oil, pharmaceutical, mining, paper, fibre, pulp, textile, food, power plants and municipal sewage facilities, public sewage, wastewater, river ponds and other industries.
