Submerged pump is a positive pressure vertical pump, which can effectively solve the problems of air resistance and cavitation. The explosion-proof grade of transported materials determines that the submerged pump products have different structure, working principle, classification, scope of application, product advantages and disadvantages and operation mode. It can be simply divided into two categories: traditional submerged pump (explosion-proof in zone 1 outside the tank and non explosion-proof in Zone 0 inside the tank) and new submerged pump (explosion-proof in zone 1 outside the tank and explosion-proof in Zone 0 inside the tank).
