The cam rotor pump is a rotary displacement pump manufactured by DURREX after decades of research and development. The professional manufacturing technology and machining accuracy of the product have reached the international advanced level. The manufacturing standards for cam rotor pumps are divided into five series: food grade, chemical grade, ordinary type, oilfield type, and special type. The core components and sealing devices of the products are made of different materials and sealing forms according to the different characteristics of the medium to meet the needs of various materials and production processes. DURREX has 12 types of rotor designs, each of which can be interchanged and used on the same pump.

4.Introduction to rotor

① One blade rotor: suitable for conveying media containing large particles, with low crushing rate for large particles, but with high pulsation, low pressure, small volume, and rarely used. ② Two blade rotor: suitable for conveying media containing small and medium-sized particles, with a relatively low crushing rate for small and medium-sized particles, slight pulsation, and a smaller volume than a three blade rotor. ③ Three bladed rotor: a universal type of rotor with a larger volume than other types of rotors and better performance indicators than one or two bladed rotors, but it has a certain degree of crushing rate on granular materials during material transportation. ④ Four to twelve blade rotors: When the rotor blades exceed three blades, their volume decreases due to the increase of rotor blades. The more rotor blades there are, the less volume there is. Multi blade rotors have relatively improved stability when transporting materials, but they are prone to crushing granular materials during transportation.

5.Sealing Introduction

A: Mechanical seal B: Water cooled mechanical seal C: Oil lubricated mechanical seal material: Hard alloy, silicon carbide, graphite... D: Packing seal material: self-lubricating polytetrafluoroethylene fiber...

6. Product features  Maintain a certain gap between rotors and rotors, rotor and pump body, no friction coefficient, long service life. Easy to assemble and disassemble, easy to maintain and clean, with few vulnerable parts. Efficient and energy-saving, low failure rate, reliable sealing, and low noise. After using special materials, it can transport media containing solid particles such as sludge and sewage. ④ Transportable medium viscosity ≤ 2 million cp, and slurry with a solid content of 60%. ④ After configuring the frequency converter, the flow rate can be adjusted freely and it can be used as a general metering pump. According to user connection requirements, flange type, screw type, and card type can be selected. @Can transport mixed materials of air, liquid, and solid phases. The 0 insulation cooling pump adopts a built-in structure with good insulation performance. The 0 mobile pump can suction various barrel materials, with a suction vacuum degree of 0.08Mpa. According to user requirements, a sanitary safety valve can be configured on the pump head.
