Product Introduction

1、 Overview

FJXThe evaporative crystallization circulation pump is a high flow, low head axial flow pump suitable for evaporation and concentration in industries such as diaphragm caustic soda, phosphate fertilizer, alumina, titanium dioxide, ammonium chloride, calcium chloride, sugar, salt, paper, and wastewater.

Structural Features
Good anti cavitation performance: suitable for low-level evaporators, significantly reducing investment in evaporation plants. It is also suitable for new evaporators with high fluid resistance heating chambers on the inlet side of the pump (reverse circulation evaporator, dual heating chamber series evaporator).
High pump efficiency and wide high-efficiency zone: By changing the blade installation angle and speed, users' requirements for flow rate and head can be met, and the operating conditions of the pump can be located within the high-efficiency zone of the pump, resulting in significant energy-saving effects.
Slow type: The pump runs smoothly; The overcurrent components have light wear and long service life; Low degree of crystal damage, suitable for evaporative crystallization process.
Cantilever rotor: Compared with the double support type, the number of shaft seals is halved, the pump is lightweight, the external dimensions are small, and the maintenance is convenient.
Pump body center support: Compared with the pump body foot support type, the rotor has better thermal neutrality.
Rear door structure: The rotor can be extracted without disassembling the inlet and outlet flanges of the pump body, making maintenance convenient and quick. Advanced shaft seal: using containerized machine seal, with a long service life6-12Months; Seal with a new type of liquid blocking packing, ensuring the longevity of the packing3-6A month.

Evaporator without expansion joint: can be used for elastic pump base or suspended pump, reliable thermal compensation, reducing evaporator investment.

Good overall reliability: The pump shaft has high strength, the bearing capacity is large, the bearing seat has a water-cooled sleeve, the shaft seal has a long service life, and the material performance is good, ensuring long-term operation of the single pump.
3、 Transmission mode
Direct connection: The pump and motor are directly connected through a flexible coupling (code name)D）.
Belt drive: It is easy to adjust the pump performance by changing the speed through a triangular belt drive (code name)V）
Reducer: Reduce speed through a gearbox, suitable for high-power pumps (code name)G）
