Selection and Characteristics of WFB Self - priming Pump

WFB-type self-priming pump selection and characteristics of I. Overview WFB series of non-sealed self-priming pump is to fill gaps in the first product, the product has temperature and pressure, "a drainage", "lifelong self-absorption" and so on A variety of functions. Currently producing stainless steel, polypropylene, cast steel, cast iron and other materials of the series machine, a total of five different shapes a total of more than 1,000 kinds of specifications. In the electronics, power, chemical, metallurgy, medicine, food, electroplating, environmental protection, fire protection, municipal services, water purification, defense industry, textile printing and dyeing, mining and dressing, civil construction and other industries widely used, praised by users. Centrifugal pump Second, the unique advantages 1, the use of "pump with a multi-faceted centrifugal seal", to get rid of the traditional pump packing seal, packing, mechanical seal, completely uniforms, "run, run, drip, leak" is The original alternative to all kinds of long axis submerged pump, submersible pumps, submersible sewage pumps and other equipment ideal. 2, the operation of the seal is not friction, no damage, the service life of more than 10 times longer than similar products. 3, the principle of transplanting vacuum pump, self-priming performance is stable and reliable, especially the use of "electric air control valve", truly "a drainage, lifelong self-absorption." 4, small vibration, low noise, flexible mobile, easy to disassemble, easy to install, without foot fixed. 5, with superior self-control function, can be used in conjunction with high-tech fields and a high degree of automation systems. Third, the use of different shapes Features Rectangular, conical to provide you with different forms of installation options; Explosion-proof for flammable, explosive environment; outdoor with a safe three-dimensional outdoor cover, open-air work in the case , Effective anti-rain, anti-fog, moisture-proof, moisture-proof; mobile cart can be pushed to the pump you need to work on the station. Fourth, on the matching motor power In order to support a reasonable motor, we learn from the advanced experience of developed countries, the pump is divided into A, B, C three conditions to adapt to the level. If you use the B, C-class conditions, according to the specific circumstances, a corresponding reduction in motor power. Class A working conditions are: continuous operation, suction stroke, flow, lift three performance standards (selected models of the required standard); B-class conditions are: continuous operation, only two of the three performance standards; C-class conditions are: continuous operation, only one of the three performance standards; Fifth, selection methods (1) performance parameters in the "Category Code" column 1-5 meanings: 1 is rectangular, 2 Conical type, type 3 for the explosion-proof type, 4 for the outdoor type, 5-type mobile cart. "Material symbol" column T, G, PP, BXG four letters represent: iron, steel, polypropylene, stainless steel (1Cr18Ni9Ti) four kinds of material. (2) Examples of model meanings: 50 WFB-AD1 50 Suction nozzle diameter (mm) WFB seal-less self-priming pump AD1 performance classification (3) Complete model writing. Assuming the requirements of the pump are: the model is a mobile cart, the material is polypropylene, and the suction diameter is 50mm. The performance is classified as AD1. The complete model of this pump is "5PP50WFB-AD1". (4) The pump flange manufactured using the national standards of the People's Republic of China. Standard code GB9115.2-88; GB9115.3-88. Non-metallic pump flange pressure 0.6MPa; metal flange pump pressure 1.0MPa. The company pump factory, the inlet and outlet with an anti-flange

Frangipani oil has a strong, rich, heady and exotic fragrance that makes it valuable in perfumery. Also its deep and long-lasting fragrance and deep cleaning properties that make it useful for skin creams, soap and lotions.

The oil is either clear or pale yellow and is slightly viscous. Frangipani is also known as plumeria.
