WFB seal-free self-priming pump
Product Introduction
WFB seal-free automatic self-priming pump is an improved and innovative product based on the advanced experience of related products. It is a replacement product for traditional similar products. This product has the advantages of temperature resistance, pressure resistance and wear resistance. The product is made of cast iron, cast steel, stainless steel, reinforced polypropylene and other materials, with various shapes and specifications. This product also has the functions of high efficiency, energy saving and unique structure.
Product Advantages
● The seal is reliable and adopts a leak-free sealing device, which is composed of a dynamic seal and an auxiliary seal.
● It replaces the packing seal and mechanical seal of the traditional water pump, and completely solves the problems of running, bubbling, dripping and leakage of the traditional seal.
● It is an ideal product to replace the original long-axis submersible pump, deep well submersible pump, submersible sewage pump, etc.
● The sealing device of the self-priming pump has no friction or wear during operation, and its service life is more than 10 times longer than that of traditional products. The self-priming performance of the transplanted vacuum pump principle is stable and reliable.
● The use of “electric air control valve” can achieve long-term self-priming. The pump unit has low vibration, low noise, flexible movement and easy disassembly and assembly.
● It has excellent self-control function and can be matched with relevant control systems to achieve high degree of automation.
● The pump is available in cone type, rectangular type, explosion-proof type, outdoor type, and cart-mobile type. You can choose according to the installation space on site.
Scope of application
● Municipal sewage engineering, river and pond breeding, electricity, chemical industry, metallurgy, medicine, food, fire protection, environmental protection, electroplating, water purification, municipal administration, national defense, textile, papermaking, mining, construction and other industries.
● The explosion-proof type is suitable for flammable and explosive environments; the outdoor type is equipped with an outdoor motor and can be used in open air situations; the cart-mobile type can push the water pump to any work site you need.
Matching motor power description
In order to reasonably match the motor, we divide the water pump into three working conditions: A, B, and C. The motor power in this sample is matched according to the A level. If you use it in B or C working conditions, you can appropriately reduce the motor power according to the specific situation. The working condition levels are divided as follows:
● Class A operating conditions are: continuous operation, suction lift, flow rate and head all must meet the standards.
● Class B operating conditions are: continuous operation, only two of the three performance items need to meet the standards.
● Class C operating conditions are: interval operation, only one of the three performance items needs to meet the standard.
