Product Overview

The main feature of the up-down cam-type rotor pump is its vertical up-down flow direction for suction and discharge. This pump meets the requirement for simplifying pipeline arrangement in certain operating conditions, thereby reducing pipeline layout costs. It also has certain advantages in pipeline and pump chamber cleaning. The vertical flow direction is more conducive to thoroughly draining the stored material within the pump, better meeting the on-site hygiene and cleanliness requirements.

Product Description

A cam rotor pump is a positive displacement pump featuring a pair of cams rotating in sync in opposite directions within its chamber. Our company is committed to integrating product development with practical applications, continuously improving and upgrading our products. Based on years of research and experience, we have determined a series of cam rotor pumps for various operating conditions: chemical, food, and general-purpose types, among others. Depending on the operating conditions and the medium being conveyed, the pumps are configured accordingly. This ensures that the cam rotor pumps operate stably, efficiently, and safely across a wide range of applications, providing fluid transport solutions that meet the actual requirements of diverse operating conditions.

Working Principle

The cam rotor pump has multiple volume chambers formed by two rotors and the pump housing. When the two rotors rotate in opposite directions synchronously, these volume chambers cyclically decrease in size and then increase 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 flow rate depends on the volume of the working chamber and the frequency of its change per unit time, and is theoretically independent of the discharge pressure. Under the drive of the transmission shaft, two rotors that rotate synchronously in opposite directions (with 1-8 blades) generate suction (vacuum) at the inlet as the volume increases during rotation. After that, the two rotors and the pump housing form a fixed volume chamber, where the volume decreases at the pump outlet, thus discharging the material. This creates a high vacuum and conveying pressure.
