The price of the same type of stainless steel rotor pump will be different. This is because even if a type of stainless steel rotor pump is used, in order to meet the requirements under different working conditions, there will be differences in parts materials, pump body materials and corrosion resistance as well as machinery. For example, the pump shaft of a stainless steel rotor pump can be made of 45 steel, 40Cr and 42Cr.

The Rotary lobe pump is a kind of volumetric pump which changes the volume of the pump through a pair of synchronous rotating rotors, forming a higher vacuum and discharge pressure, so as to achieve the purpose of conveying fluid. Attention should be paid to the matters needing attention when using rotor pumps.

When the pump reaches the normal speed, observe the pressure index of the rotary lobe pump. When the rotary lobe pump installation position has suction requirements, should be in the pump inlet pipe and pump cavity filled with material. When the process requires heating or cooling of the medium, the heating or cooling device should be opened before opening the rotary lobe pump, the heating energy half should be opened 10 minutes in advance, and then the rotary lobe pump.

The rotor pump has a simple structure and can be repaired on-line without dismantling pipes or tools. It can be maintained online by replacing high-strength protective covers and simple mechanical seals. It is mainly reflected in the overall design of the pump cover, the versatility of accessories and simple structural design.

High viscosity rotor pump is a new type of volumetric pump developed according to the needs of petroleum, chemical industry, paint, grease, medicine, dye, food and other industries. Because the product can choose different materials and its structure, it is widely used in the transportation of media with different properties and different viscosity.

Screw pumps are divided into three types: single screw pump, twin screw pump and triple screw pump.The single screw pump is mainly composed of a screw rotor and a rubber stator. The motor drives the rotor to rotate, and the rotor and the stator form a dynamic closed volume cavity. As the helix moves forward, it will achieve the purpose of conveying the medium.
