Product Description
overview
This is an energy-efficient and non-clogging self-priming sewage pump. It is developed with the advanced technology of similar products at home and abroad. All performance indexes have reached the technical level of similar foreign products. Due to the unique open impeller, the mechanical seal static and dynamic ring adopts special hard. The quality of the alloy material, the entire sealing system completely cites foreign technology, has the characteristics of no clogging, long sealing life, convenient maintenance and high efficiency, and is well received by customers.China kemai brand zw series self-priming sewage pump is a novel product successfully developed on the basis of repeated research on similar products at home and abroad. The pump integrates self-priming and non-blocking sewage, and adopts axial reflow mixing. And through the pump body. The unique design of the impeller flow channel, like the general self-priming pump, does not need to install the bottom valve and the irrigation water, but also can absorb the large particles of solid and long fiber impurities. It is widely used in municipal sewage treatment projects, river pond culture manure treatment, sedimentation of waste minerals, light chemicals, paper, food, chemical, pharmaceutical, electric power, propellers and mixtures.
Compared with domestic similar products, the pump has the advantages of simple structure, good self-priming performance, (self-priming height up to 5m), strong sewage discharge capacity, high efficiency and energy saving, convenient maintenance (completely replace WQ, QW submersible sewage pump) and so on. It is the first in China in the series of sewage pump products. The technical indicators are leading domestically and reach the international advanced level. Has a broad application market development prospects.
Self-priming Sewage Pump Features
1. Strong overcurrent capability: special impeller anti-blocking design ensures efficient and non-blocking of the pump;
2, high efficiency and energy saving: the use of excellent hydraulic model, the efficiency is 3 to 5% higher than the ordinary self-priming centrifugal pump;
3, self-priming performance: self-priming height is 1 meter higher than the general self-priming pump, and the self-priming time is shorter than the ordinary self-priming pump.
ZW Self-priming Sewage Pump Structure introduction
This series non-blocking sewage pump, in order to meet the different requirements of the user, the material is carbon steel, stainless steel, and can be equipped with explosion-proof motor, the structure consists of two parts: electric motor and water pump.
1. The motor adopts Y series asynchronous motor and Class B insulation.
2. The pump part is located at the other end of the motor. The pump impeller is open type, strong in discharge capacity, not easy to block, pumping dirty liquid containing fibrous substances and suspended solid particles, advanced sealing technology and long service life.
