Sea Water Submersible Pumps Types

Sea water pump specifications mainly refers to two types for their pump shell. One is diversion shell type whereas the other being normal pump shell. Head of diversion shell types ranges among 30-100m, belonging to low head pump type. On the contrary, pump shell owns the property of large capacity and high head, water is filled into pumps motor to cool down heated machine. The average output reaches 10t/h or 20t/h. Therefore, it becomes the primary and hot type in our company.

Sea Water Submersible Pumps Working Principle

Motor of sea water pumps is used to offer power, when pump is on, motor starts working rapidly and drive each parts of pumps move accordingly. Vacuum space is formed near inlet because of imbalanced pressure between water and pumps, therefore, sea water is forced to flow into pump body under great pressure. Near impeller part, fast rotated impeller brings liquid rotate in pre-designed route and then throw water away in large force. The height of water thrown is defined as head of pumps. Then all the water flows out through outlet naturally, that is the whole working process of water pumps.

Sea Water Submersible Pumps System

As a marine pump, whole pump body must be immersed totally into water, for easy operating, we equip switch of it on the ground. A weak submersible pump may get sick in smooth working conditions and curve. However, each of pump produced in our company must be tested repeatedly for better performance. And in order to get it worked more fluency, we compared many sorts of hydraulic design and chose the perfect one as main type. Noisy during working process is narrowed in largest extent by high quality rubber. As a professional submersible pumps company, we exert to bring you the most comfortable using experience.

Sea Water Submersible Pumps Parts

Four main parts form water pumps all together, which includes impeller, motor, inlet and outlet. Unlike on-ground water pumps, submersible pumps put pump body and motor together as one whole to save space. Unlike other clean water pumps, sea water submersible pumps impellers must be also corrosion resistant, therefore, we design them into typical type and can better transfer small particles and solid. Inlet is covered with filter to block impurity and makes sure more water can be pumped in. Outlet is installed above impeller part, after water is thrown away from impeller, it flows out directly from outlet.

Sea Water Submersible Pumps Materials

Internal materials have large effect on pumps performance and service life, before choosing suitable materials, APK did quantity of submersible pumps experiments and hydraulic test. Taking safety as primary matter, we equipped our pumps with over-heat and over-flow devices to protect motors. Silicon steel sheet and copper wire we use are far beyond national standard. Instead of manual pumping, we use stamping machine which requires accurate size and thickness. Therefore, our stator is made smooth and close.
