WFB series of seal-less self-control self-priming pump adopts no-leakage V-type seal assembly, eliminating the traditional pump packing seal, packing seal, mechanical seal, completely subdued the running, bubbling, dripping, leakingâ??, is to replace the original variety of long-shaft submerged pumps, submersible pumps, submersible pumps, etc. Ideal equipment. Disadvantages of the structure of the pump: First, downtime liquid leakage along the direction of the shaft outward, for frequent starting equipment is not very suitable for the occasion; Second, the power consumed by the secondary impeller is too large, the pump efficiency is low.WFB improved structure for the sealing device, one is to improve the efficiency of the pump, the second is to reduce the power of the motor, the third is to inhibit the leakage of the pump shutdown phenomenon. Sealing device in the movement process without friction, no wear and tear, the service life is more than 10 times longer than similar products. Transplantation of the vacuum pump principle, self-absorption performance is stable and reliable, in particular, the use of â??electric air control valveâ?? truly realised â??a diversion, life-long self-absorptionâ??. High efficiency, low vibration, low noise, flexible movement, easy disassembly, easy to install, no need for foot fixing, eliminating the difficulties of transporting, installing and maintaining the long-shaft submerged pump. With superior self-control function, it can be used with high-tech fields and highly automated series.
Monoblock pumps -
Falcon centrifugal monoblock pumpsets are powered by a totally enclosed fan cooled AC induction two pole motor. Motor stator is made of low watt loss silicon steel laminations assembled under pressure and rigidly locked in the
frame. The windings are of high-grade enameled copper wire offer excellent resistance and are varnish impregnated. Construction of motor frame and usage of quality materials result in high performance and low temperature rise
thereby increasing the life cycle of the motor.

Pipeline centrifugal pumps are general-purpose equipment for conveying clear water and liquids with similar physical and chemical properties, widely used in industrial and urban water supply and drainage, high-rise building pressure boosting, fire-fighting systems, HVAC circulation and other fields [2]. According to the installation form can be divided into vertical and horizontal, according to the impeller structure is divided into closed, open and semi-open [1], the adaptable medium temperature range -20 â?? to 240 â?? [3], typical models include ISG, ISW, IRG, etc. [2] [4].
The equipment consists of impeller, pump body, sealing ring and other core components, the impeller rotates to generate centrifugal force to achieve liquid transport, the pump body plays a supporting role, and the sealing system to protect the operating vacuum. It adopts modular piping design, equipped with high-efficiency hydraulic model, supports electric drive and direct connection structure, featuring low noise, small footprint and easy maintenance. Installation requires precise calculation of suction height and ensuring pipeline sealing, and the performance curve reflects the relationship between flow rate, head and power [4]. Common faults such as air binding can be solved by filling water and exhausting air, and the bearings and sealing parts need to be overhauled regularly [2].
Small submersible sewage pump is a kind of sewage treatment equipment with pump and motor connected design, submerged under liquid work, widely used in municipal engineering, industrial wastewater treatment and building drainage field. The equipment adopts vertical structure, with compact structure, low noise characteristics, can be directly installed in the sewage pool operation.
Submersible sewage pumps are submersible sewage pumps that are particularly suitable for transferring liquids containing hard solids, fibrous materials, and particularly dirty, sticky and slippery liquids. There are two types: AS and AV submersible sewage pumps.
QW submersible sewage pump is a kind of pressure pump with large flow channel anti-clogging hydraulic parts design, which greatly improves the dirt passing ability.
