After fully understanding and communicating with Rohde cam rotor pumps, they replaced the sulfur
Does the gap between the rotor and the pump body affect the performance of the rotor pump? [09-03 09:35]
Rotor pump is a positive displacement pump with simple structure, long service life and reliable component parts. It has been widely used in domestic sewage, urban sludge, high viscosity liquids and petrochemical oil products. However, in the actual manufacturing process, the gap between the surface of the rotor and the pump body is designed based on experience, and no specific data analysis has been performed. The gap between the rotor and the pump body has a certain effect on the volumetric efficiency of the three-lobed arc cam rotor pump. The impact of the gap on the volume efficiency of common metal rotor pumps is usually related to the viscosity of the medium. The larger the viscosity, the smaller the impact. The rubber rotor pump has a smaller gap when designing the rotor due to the complexity of the medium it transports. The viscosity of the medium has little effect on its volumetric efficiency. If you have any other questions about the rotor pump, please call 400-80

Is the cam rotor pump resistant to wear when handling farm manure? [03-07 09:02]
The fecal fluid is characterized by high solids content, high viscosity, and great wear on the conveying parts inside the pump. This is a question often asked by customers today when consulting us. The commonly used screw pump is easy to block and not wear-resistant when conveying manure from farms, and the parts are expensive, and the replacement process is complicated, which affects the overall efficiency. The cam rotor pump pump body is made of ductile iron, the rotor is made of nitrile rubber, and it is equipped with a cast steel material radial protective liner. With it, the contact area between the faecal liquid and the pump can be reduced, and the abrasion of the particulates in the faecal dirt on the pump casing of the cam rotor pump is reduced. In this way, when replacing the accessories, usually only the protective liner can be replaced. When the cam rotor pump is in use, it has a good passability for the fibrous solids contained in the fecal fluid. The cam rotor pump has the function of on-line maintenance.
