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 that the rotor pump operates stably, efficiently, and safely across a wide range of applications, providing users with fluid transportation solutions that meet the actual operating requirements.

Working Principle

The HELIS rotor pump consists of multiple volumetric chambers formed by two rotors and the pump housing. When the two rotors rotate synchronously in opposite directions, the volumetric chambers work cyclically – from small to large, to a fixed volume, and then back to small – to achieve the transfer of fluids. The motor and reducer drive the pump shaft rotation, converting electrical energy into kinetic energy of the fluid medium being conveyed through the pump. The flow rate of the pump depends on the volume of the working chamber and its frequency of change per unit time, and is independent of the discharge pressure (theoretically, and without considering the viscosity and fluidity of the material). The rotor pump, driven by a transmission shaft and synchronous gears, allows the two rotors and pump chambers to form a fixed volumetric chamber. The inlet chamber increases in volume, creating suction (vacuum) to吸入 material, while the outlet chamber decreases in volume, forming a conveying pressure to output material. The volumetric chamber characteristics of the pump allow for effective conveying of soft, easily fractured solid materials with large particle sizes, such as the fruit particle material in food materials.
