UK GRIMM Imported evaporation circulating pump summary:

           Imported evaporation circulating pump with large flow and low lift axial flow pump, the advantages of the introduction and digestion of Britain's Green of similar products, to optimize the design of the product, ensure the product reliability, economy and security. The pump is made by international standard, with high efficiency, stable performance, reliable and convenient maintenance. The product is widely used in chemical, nonferrous metals, salt making, light industry and other industries. Evaporation, crystallization, chemical reactions and other processes. Forced circulation evaporator for ammonium phosphate, phosphoric acid, vacuum salt, aluminum oxide, caustic soda, light industry and other industries to use, also can be used as a circulating pump crystallizer, reactor.

 

UK GRIMM Imported evaporation circulating pump structure characteristics:

 

 

 

 

 

 

 

The imported evaporation circulation pump mainly consists of impeller, pump body, auxiliary impeller, sealing box, intermediate support, bearing box, bearing and other parts.

1. Pump body center support: with the pump body foundation support ratio, the rotor heat is neutral.

2. Cantilever rotor: compared with the double support type, the number of sealing shaft is halved, the pump is light in weight, small in size and easy to overhaul.

3. Pump efficiency, high efficiency zone width: with the change of blade installation angle, change the speed of two ways, to meet the user flow, lift requirements, and make the pump running position in the high efficiency zone, energy-saving effect is remarkable.

4. Anti cavitation performance is good: applicable to low level evaporator, greatly reduce the evaporation workshop investment. The utility model is also suitable for the new type evaporator (reverse circulation evaporator, double heating chamber series evaporator) arranged in the heating chamber with large fluid resistance at the inlet side of the pump.

5. Low speed type: the pump runs smoothly; the over-current parts wear less light and long service life; the crystal damage is low; it is suitable for evaporation crystallization process.

6. The back door structure: no need to remove the pump body import and export flange pipe connection, you can take out the rotor, easy maintenance, quick.

7. Seal: the combination of static structure, ensure the pump will not leak in the work and the static, dynamic seal with vice impeller seal static seal with packing seal and mechanical seal; mechanical seal is divided into single face and double end in two, for the selection.

8. The evaporator has no expansion joint: it can be used as the base of elastic pump or suspension pump. The heat compensation is reliable and the investment of evaporator is reduced.

9. High reliability of the whole machine: high strength of pump shaft, large bearing capacity of bearing, water bearing sleeve of bearing seat, long life of shaft seal, good material performance, ensure long term operation of single machine.

10. Drive mode:

Direct connection: pumps and motors with winding couplings (code D).

Belt transmission: through the V-belt drive, change the speed of the pump performance is easy (code V).

Reducer: through the reduction gearbox down speed, suitable for high-power pumps (code G).
