The WFB type vertical non-sealed self-control self-priming pump has reliable sealing and adopts a non-leakage sealing device, which is specifically 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, emitting, dripping, and leaking in the traditional seal. It is mainly composed of pump body, working impeller (main impeller), auxiliary impeller, pump shaft, motor bracket, electric control valve, parking check valve and other devices.
For example: 2.3 PP200WFB-AD1
2.3 - The shape is cone-shaped explosion-proof type
PP - made of reinforced polypropylene
200 - liquid inlet diameter
WFB - sealless self-control self-priming pump
AD1 - performance Classification
Meaning of "Category Code" 1-5:
Type 1 is rectangular,
Type 2 is a cone type,
Type 3 is explosion-proof,
Type 4 is outdoor type,
Type 5 is a cart mobile type.
1. Rectangular type and conical type can be selected according to the installation space on site;
2. Explosion-proof type is suitable for flammable and explosive environment;
3. Outdoor type supporting outdoor motor, which can be used and worked in the open air;
4. The mobile cart can change the work site at any time.
The letters T, G, PP, and BXG of "Material Symbol" respectively represent:
T - iron
G - steel (carbon steel, wear-resistant steel: JM3, JM6)
PP - reinforced polypropylene
BXG - stainless steel (321, 304, 316, 316 L)
Generally used in:
WFB type self-control self-priming pump is widely used in municipal sewage engineering, river pond breeding, electric power, chemical industry, metallurgy, medicine, food, fire protection, environmental protection, electroplating, water purification, municipal administration, national defense, textile, papermaking, mining, construction and other industries
1. The sealing device is free from friction and wear during the operation of the non-sealed self-control self-priming pump.
2. Transplanting the vacuum pump principle. The self-priming performance is stable and reliable, especially the use of the "electric air control valve" to truly achieve the first drainage and permanent self-priming. The pump unit has low vibration, low noise, flexible movement, and convenient disassembly.
3. It has superior automatic control functions and can be matched with related control systems to achieve a high degree of automation.
