About submersible pumps

The submersible pump features a unique centrifugal double-balanced impeller, which is suitable for transporting clean fluids free of solid particles, offering very low vibration and noise levels as well as high efficiency. It also comes with an open-type double-balanced impeller, designed for transporting dirty liquids containing solid particles and short fibers, ensuring stable operation without clogging. Principle: Before starting the pump, the suction pipe and the pump itself must be filled with liquid. After the pump is started, the impeller rotates at high speed; the liquid inside rotates along with the blades. Under the effect of centrifugal force, the liquid is ejected outward from the impeller. As it moves through the diffusion chamber in the pump casing, its speed gradually decreases while its pressure increases, before it finally flows out through the pump outlet and the discharge pipe. At this point, a vacuum low-pressure area devoid of both air and liquid is formed at the center of the blade as the liquid is flung outward. Under the effect of the atmospheric pressure at the surface of the liquid pool, the liquid flows into the pump through the suction pipe; in this way, the liquid is continuously drawn up from the pool and then continuously discharged through the outlet pipe. Features: 1. The pump is a vertical submersible pump with an attractive design; it can be installed directly on the container holding the medium to be transported, requiring no additional space and thus reducing capital investment. 2. The mechanical seal has been removed, eliminating the problem of frequent maintenance required for other submersible pumps due to the easy wear of mechanical seals; this reduces the operating costs of the pumps and improves work efficiency. 3. The submersible pump features a unique centrifugal double-balanced impeller, designed for transporting clean fluids free of solid particles; it has extremely low vibration and noise levels as well as high efficiency ； It features an open double-balanced impeller, suitable for transporting dirty liquids containing solid particles and short fibers, offering stable operation without clogging.

A submersible pump is a type of centrifugal pump that is installed vertically, with its pump head below the liquid surface.

Working principle of submersible pumps: The working part of a submersible pump is submerged in the liquid, resulting in no leakage at the shaft seal. It also features a small footprint, reliable operation, easy maintenance, and strong corrosion resistance. It is widely applicable to industrial sectors such as chemicals, pharmaceuticals, papermaking, and petroleum. The vertical motor of the submersible pump is secured to the motor base with bolts, and it is directly connected to the pump via an elastic coupling. The pump body, intermediate connection pipe, pump frame, discharge pipe, and pipe flanges are all connected together with bolts to form a single unit, which is then fixed to the base plate; the entire pump is mounted on the container through this base plate. The axial and radial forces of the pump (including the water pressure generated during operation, as well as the weight of the impeller and rotor) are all handled by the one-way thrust ball bearings and single-row radial ball bearings installed within the bearing housing ； As well as the load borne by the sliding guide shaft to ensure the safe and normal operation of the pump. The bearings are lubricated with butter, while the guide bearings are lubricated by the liquid being transported. Therefore, the liquid level must be above the centerline of the impeller during operation. Depending on the length L of the part extending into the container, it is further divided into configurations with an intermediate guide bearing and those without an intermediate guide bearing. Structure of submersible pumps: The main components of a submersible pump include a volute, pump base, impeller, pump casing, support tube, motor base, electric motor, etc. The volute, pump base, pump casing, and impeller nut are made of pig iron, which offers good corrosion resistance and facilitates manufacturing.

In terms of sealing performance, it is indeed very reliable! ! Be careful to protect the electrodes!
