WFB self sucking pump without seal

1.overview

WFB series of self suction pump without sealing, is to fill the domestic blank of the first product, the product has a temperature resistance, "a drainage", "life-long self absorption" and other functions. At present, the production of 321, 304, 316, 316L, A3, PP (reinforced polypropylene) and other materials of a series of machine, five kinds of different shapes of a total of more than one thousand kinds of specifications. Widely used in electronics, electric power, chemical industry, metallurgy, medicine, food, electroplating, environmental protection, fire protection, municipal, water purification, defense industry, textile printing and dyeing, mining beneficiation, civil unique advantage

The company adopted the "seal" by a series of pump type centrifugal multiple surface, get rid of the traditional pump packing seal, packing seal, mechanical seal, completelysubdued "leakage", is a variety of equipment to replace the long axis of the pump, submersible pumps ideal.

Run thesealis notfriction, no mo loss, long service life,10 times lifelong than similar products

Transplantation vacuum pump principle, self suction performance is stable and reliable, especially the use of "electric air control valve", the real realization of a drainage, life-long self absorption".

small vibration, low noise, flexible movement, easy disassembly, easy installation, no foot fixed.

With superior automatic control function, can be used in the field of high technology and automation system.

characteristics of Different shapes

Rectangular and conical provides different choices of installation forms for you ;Explosion proof type suitable for inflammable and explosive environment; outdoor type uses the safety cover with stereo households. In the open-operating conditions, owns effective waterproof, anti fog, moisture-proof, anti wet properties; mobile carts can pump over any position you need on the job.

2.Instructions on matching motor power

In order to reasonable matching motor, we learn from the advanced experience of the developed countries, the pump is divided into A, B, C three kinds of operating conditions to adapt to the level of the motor power, the specification is based on the level of matching. If you use the C, B level conditions, according to the specific circumstances, the corresponding reduction in supporting motor power.

3.Selection method

Performance parameter table in the "category code" column of the meaning of the 1-5: 1 for the rectangular type, type 2 for the cone type, type 3 for the explosion-proof type, type 4 for the outdoor type, type 5 for the cart move. Material symbol column G, PP, BXG four groups of letters on behalf of: steel, reinforced polypropylene, stainless steel (1Cr18Ni9Ti) four kinds of materials.

Full model writing. Assume that the pump requirements are: Modeling for the mobile carts, made of reinforced polypropylene, suction diameter for 50mm performance classification AD1. The full model of the pump is "5PP50WFB-AD1" "

Assuming that the pump is a rectangular type of explosion-proof type, other requirements as above, the complete model of the pump should be written as 1.3PP50WFB-AD1"

Assume that the pump model is a conical explosion-proof type, other requirements as above, the complete model of the pump should be written as 2.4PP50WFB-AD1"

the flange of the pump is made of People's Republic of China national standard. Standard code GB9115.2-88; GB9115.3-88. Non metallic water pump flange pressure 0.6MPa; metal water pump flange pressure 1.0MPa. The company pump factory, the import and export with a counter flange.
