1、 Product Overview

FJX forced circulation pump is a large flow, low lift axial flow pump. FJX evaporation circulating pump is manufactured according to international general standards, which is efficient, energy-saving and easy to maintain. It is applicable to evaporation, concentration and cooling of diaphragm caustic soda, phosphoric acid, sugar making, molten salt, paper making, waste water and other industries. In order to improve the production capacity of the equipment, the heat transfer coefficient of the heat exchanger is increased for forced circulation. Installation position: the ground foundation (elastic support can be configured according to user needs) is directly suspended on the evaporator. Pump type: vertical and horizontal. Transmission mode: direct transmission, belt transmission, hydraulic coupling, universal joint transmission. Sealing structure: combined mechanical seal and packing seal. Manufacturing method of pump body: casting and welding.
