Differences between cam rotor pumps and other positive displacement pumps

Thread Content

Differences between cam rotor pumps and other positive displacement pumps: 1. There is no friction at all, resulting in a long service life for the pump. 2.304/316 material, high cleaning grade, suitable for transporting food and pharmaceuticals. 3. The mechanical seal is protected by a base, reducing the risk of leakage; it usually can last for over 4 years. 4. It has a wide range of applications in planning, and can transport materials with high viscosity and concentration, large particles, as well as gas-liquid-solid mixtures. Disadvantages: 1. Its self-priming capacity is inferior to that of gear pumps and screw pumps. 2. High prices. The cam rotor pump is a versatile two-way positive displacement pump, also known as a Roots pump, stainless steel rotor pump, cam pump, universal transfer pump, thermosol pump, particle colloid pump, sludge pump, protein sludge pump, high-concentration slurry pump, etc. The manufacturing technology and precision of these products are on par with those of similar foreign products. This product uses two rotors that move in synchronization; these rotors are driven by a pair of external synchronous gearboxes. Driven by the shafts, the rotors rotate in opposite directions in sync, thereby creating a high vacuum level and discharge pressure. It is particularly suitable for transporting medical-grade fluids as well as highly corrosive and viscous fluids. This product is widely used in industries such as petrochemicals, fine chemicals, daily chemical products, pharmaceuticals, food processing, environmental protection, papermaking, coatings, and metallurgy. It has received positive feedback from users in its role as a replacement for imported pumps. Features of cam rotor pumps: A certain gap is maintained between the rotors, with no friction coefficient, resulting in a long service life. Easy to assemble and disassemble, convenient for protection and cleaning, with few vulnerable parts. Highly efficient and energy-saving, smooth operation, low failure rate, reliable sealing, and low noise. It ensures the reliability of continuous operation as well as leak-free operation at all times. By using special materials, it is possible to transport media containing solid particles such as sludge and wastewater. It can transport media with a viscosity of ≤500000 cp, as well as slurries with a solid content of 70%. It can transport mixtures of gas, liquid, and solid phase flows. With an inverter installed, the flow rate can be adjusted as desired, and it can be used as a regular metering pump. Insulation equipment can be added to the pump casing according to the user’s requirements. Applicable temperature: -20°C to 180°C. Depending on the user’s connection requirements, the interfaces available are flange type, threaded type, and quick-install type. Shanghai Shengou Pump Valve Co., Ltd. 021-54148004
