Centrifugal Submersible Pumps Shaft

Rotor shaft sleeve of centrifugal submersible pumps is easily got loosen or fallen off, in order to overcome the problem, we made improvement in producing process. All shaft materials changed into the fields of chromium, original adhesive method is also replaced. Therefore, phenomenon of loosen shaft sleeve is overcame. Other internal materials such as copper wire and steel plate are also far beyond national standard. With accurate CNC machine and multi-functional high speed stamping machine, each parts and accessories are made accurately, quality of products are improved to large extent. All the producing process will be completed under strict monitor and test, special person is designated to be responsible for each step.

Classifications Of Centrifugal Submersible Pumps

Centrifugal pumps adopt centrifugal impeller, because of its excellent performance, most well water pumps adopt centrifugal types. Among them include deep well water pumps, fountain water pumps and small submersible pumps. According to pumps castings, they can be divided into cast iron pumps and stainless steel types. Cast iron types fit nearly all applications because of their wear resistance and hardness. While transferring hot water or drinking water, we suggest stainless steel centrifugal pumps. All the centrifugal submersible water pumps are for hot sale. As diameter and features of transferred medium are different, we will have professional staff to introduce pumps for you in detail.
