UK GRIMM imported axial flow pump summary:

imported chemical axial pump is a new product developed by Green in Britain. It is divided into 9 models and 18 specifications according to the caliber: 250, 300, 350, 450, 500, 600,, 700, 800, and 900. The utility model has the advantages of good reliability and convenient maintenance, and is an axial-flow pump specially designed for the characteristics of evaporation and circulation engineering in chlor alkali and salt making. based on the success in the technology industry, and into the design director of itself, by driving the optimization design and operation of small vibration, low noise, greatly improves the reliability and balance of the axial flow pump, the maintenance period and the service life is greatly increased. The operation reliability is high, the maintenance cycle is more than doubled, and the service life is increased by 20%.

A corrosive liquid capable of delivering chemical, neutral, corrosive, cold, or hot, clean or contaminated, suspended, or a large amount of crystalline particles.

UK GRIMM imported axial flow pump structure characteristics:

According to the lifting line theory, draw propeller design experience, the development of the design method of axial flow pump with variable circulation distribution along the radial direction, and the model test is carried out and compared with the same type of axial flow pump has the advantages of small size, light weight, good rigidity, high efficiency (compared with the British first generation Green chemical axial flow the pump efficiency is increased by more than 10%, weight more than 30%). As viewed from the drive side, the pump rotates counter clockwise.

UK GRIMM imported axial flow pump design features:

imported axial flow pump adopts cantilever support type, single stage single suction axial flow impeller. The motor adopts straight belt or belt drive. The utility model adopts the structure of a back door, so that when the seal is repaired or replaced, only the rotating part can be drawn out, and the pipe is not needed to be disassembled, so the utility model has the advantages of convenient maintenance. Sealing type can use double end mechanical seal or packing seal. The pump body adopts a bent pipe type or a volute type structure, and the inlet and outlet of the pump have the same caliber. The bearing housing is provided with a water cooling cavity for cooling the bearing by cooling water. For the suspension structure or elastic foundation type axial flow pump for the special design.

UK GRIMM imported axial flow pump technical parameter:

Flow rate: 200 ~ 12000m3/h

Lift: 2 ~ 12m

Speed: 580 ~ 1450r/min

Power: 7.5 ~ 250KW

Caliber: 250 ~ 900mm

Design pressure: 0.4MPa

Working pressure: 1.0MPa

Operating temperature: -0 ~ 180 DEG C

UK GRIMM imported axial flow pump seal up:

The radial vibration pendulum at the sealing cavity is less than 0.5mm, which ensures the reliability and durability of the seal and prolongs the maintenance period. Packing seals and single or double end mechanical seals can be installed, and power seals can be installed for special occasions.

Viton and other synthetic rubber are used in the fixed seal.

Fillers are made of asbestos, carbon fiber, flexible graphite and other corrosion-resistant materials.

UK GRIMM imported axial flow pump texture of material:

The flow components available 1Cr18Ni9, 1Cr18Ni12Mo2Ti, 1Cr18Ni12Mo3Ti, and other materials for colo 804 manufacturing. A variety of strong corrosion materials with a temperature of 0~180.

UK GRIMM imported axial flow pump purpose:

imported axial flow pumps are mainly used in large flow and low lift occasions, especially for forced circulation processes with corrosive media. For example, the mandatory cycle of caustic soda and salt production is also applied to phosphate fertilizer, oil, chemical fiber, paper making, and other production sectors.
