Stainless steel water pumps will have a layer of bai coating on the outside, which is not easy to break. Advantages of stainless steel pumps: 1. The stainless steel pump has a compact structure and a small footprint. 2. Since the stainless steel pump works under the liquid, it can be directly installed in the sewage tank. There is no need to build a special pump room to install pumps and machines, which can save a lot of land and infrastructure costs. 3. Easy maintenance of stainless steel pump device. Small stainless steel gear pumps can be installed freely, and large stainless steel gear pumps are usually equipped with automatic coupling installations that can stop automatic devices. The installation and maintenance are quite convenient.

 

The stainless steel pump has a long continuous operation time. As the stainless steel gear pump and the motor are coaxial, the shaft is short, and the rotating parts are light in weight, the load (radial) on the bearing is relatively small, and the service life is much longer than ordinary pumps. 5. The stainless steel pump does not have the problems of cavitation damage and water diversion. Especially the latter point brings great convenience to the operators. But everything is divided into two. The most critical issue for stainless steel pumps is usability. Because stainless steel pumps are used under liquid; the conveying medium is some mixed liquid containing solid materials; pump and motor Very close; the pump is a vertical arrangement, and the weight of the rotating parts is in the same direction as the impeller receiving water pressure. These problems make stainless steel gear pumps have higher requirements than ordinary sewage pumps in terms of sealing, motor load capacity, bearing arrangement and selection.
