Manual Mechanical Variable Speed - Cam-Type Rotor Pump

Product Overview

Manual mechanical speed regulating cam rotor pump equipped with a manual mechanical speed regulating reducer. The pump's main feature is that the speed of the reducer can be adjusted by turning the handwheel of the speed reducer, thereby regulating the pump's rotational speed. It is commonly used in operating conditions that require adjustable pump speed, enabling simple and efficient speed adjustment, thus regulating the pump's output flow rate and pressure.

Product Introduction

The cam rotor pump is a positive displacement pump featuring a pair of cams rotating in sync in opposite directions within its pump chamber. Our company has always been 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, general-purpose, and more. Depending on the operating conditions and the medium being conveyed, the products are configured accordingly. This ensures that the rotor pumps operate stably, efficiently, and safely across a wide range of applications, providing users with fluid transport solutions that meet the actual requirements of their operating conditions.

Working Principle

The cam rotor pump features multiple chambers formed by two rotors and the pump body. As the two rotors rotate synchronously in opposite directions, these chambers cyclically expand and contract to transport fluids. The mechanical energy input to the pump's main shaft is converted into kinetic energy of the fluid being transported. The pump's flow rate depends on the volume of the working chamber and its frequency of change per unit time, and is theoretically unrelated to the discharge pressure. Driven by the transmission shaft, the two rotors (with 1-8 blades) rotate synchronously in opposite directions. During rotation, they create suction (vacuum) at the inlet as the volume increases. Subsequently, the two rotors and the pump body form a fixed volume chamber, and as the volume decreases at the pump's outlet, the material is discharged, resulting in high vacuum and transport pressure.
