Product Description

A positive displacement pump, the rotor pump features a pair of cams rotating in opposite directions within its pump chamber. Our company is committed to integrating technology development with practical applications, continuously upgrading and refining our products. Based on years of research and experience, we have determined a series of rotor pumps for various operating conditions: chemical, food, and general-purpose types, among others. Depending on the operating conditions and the medium being transported, the product utilizes the appropriate configuration. This ensures the rotor pump operates stably, efficiently, and safely across a wide range of applications, providing users with fluid transportation solutions that meet actual operating requirements.

Operating Principle

The Helix rotor pump consists of multiple chambers formed by two rotors and the pump body. When the two rotors rotate synchronously in opposite directions, the chambers work cyclically—expanding, reaching a fixed volume, and then contracting—to transport fluids. The motor and reducer drive the pump shaft, converting electrical energy into kinetic energy of the transported fluid medium. The pump flow rate depends on the volume of the working chamber and its frequency of change per unit time, and is unrelated to the discharge pressure (theoretically, and not considering the viscosity and fluidity of the material); the rotor pump, driven by a drive shaft and synchronized gears, allows two rotors to rotate synchronously in opposite directions, forming a fixed volume chamber during rotation. The chambers, respectively, produce suction (vacuum) by expanding from small to large at the inlet to intake material, and contract from large to small at the outlet to form a transport pressure, thus outputting the material. The pump's volume chamber characteristics enable efficient transport of soft, friable solid materials with large particle sizes, such as fruit-pulp-containing food materials.
