PRODUCT DESCRIPTION
The rotor pump is a positive displacement pump, a medium-pressure single-acting quantitative vane pump. It uses the periodic conversion of multiple fixed-volume delivery units in the pump cavity to deliver fluid. A cavity is formed between the pump body and the rotor by eccentricity. When the motor drives the shaft to rotate through the belt pulley, the blades in the rotor slot are attached to the pump body wall of the cam rotor pump due to centrifugal force. When the blades start to turn from the tip of the cavity to the middle, the space between two adjacent blades and the pump body gradually becomes larger, completing the suction process. After passing the midpoint, the space of the cam rotor pump gradually changes from large to small, completing the discharging process, and the material is pressed out from the outlet at the other tip of the cavity. It is especially suitable for the transportation of sanitary media and corrosive and high viscosity media.
Transmission Section Selection:
•Motor + Fixed Ratio Reducer: this method of transmission is simple, the rotor speed is constant, which also determines the flow rate is not adjustable.
• Motor + Mechanical Friction Type Stepless Transmission: this type of transmission is manually adjusted to achieve variable speed. It is characterized by safe and reliable, large torque, flow adjustable stepless. Disadvantages are non-automatic adjustment and more troublesome. The speed must be adjusted in the working process, and it must not be adjusted under stop state. Please refer to the manufacturer’s instructions for use and maintenance specifications.
•Converter Motor + Converter: the speed can be automatically adjusted in this way, which means that the flow can be adjusted steplessly. The advantage is that the degree of automation is high and the low speed torque is large; the disadvantage is that the price of the inverter is relatively high. Please refer to the manufacturer’s instruction manual for maintenance specifications.

WORKING PRINCIPLE
The rotor pump is also called colloid pump, tri-lobe pump, shoe sole pump, etc. It relies on two synchronous and counter-rotating rotors (normally 2-4 teeth) to generate suction (vacuum) at the inlet during the rotation to suck the material.
The rotors divide the rotor chamber into several small spaces and runs in the order of a—b-*c—d. When running to position a, only chamber I is filled with medium;
When it reaches position b, part of the medium is closed in chamber B;
When it reaches position c, the medium is also closed in chamber A;
When it reaches position d, chambers A and B are connected to chamber II, and the medium is transported to the discharge port.
In this way, the medium is continuously transported out.
The lobe pump is a multi-purpose transfer pump which adopts two-lobe, tri-lobe, butterfly or multi-lobe rotor. As a sanitary volumetric delivery pump, it has the characteristics of low speed, high output torque, high temperature resistance, corrosion resistance, etc. Its unique working principle and characteristics are embodied in conveying high viscosity, high temperature, and highly corrosive materials. Its conveying process is smooth and continuous, and it can ensure that the physical properties of the materials are not broken during the conveying process, and the viscosity of the conveyable materials can be up to 1,000,000 CP.
APPLICATION CHARACTERISTICS
APPLICATION CHARACTERISTICS
High Viscosity Material Transfer Pump
As a positive displacement pump, it has low speed, high output torque and high temperature resistance, making it especially suitable for conveying high viscosity and high temperature materials. Its unique working principle combined with a powerful drive system ensures that the rotor pump can output a powerful drive torque at low speeds. It is ensured that the material is conveyed continuously and without stagnation, and that the properties of the material are not destroyed during the conveying process. The pump can deliver media with viscosities up to 1000000CP.
Thin Media Transfer Pump
Rotor pumps have a comparative advantage when transporting particularly thin media, especially when it is required to output a thin medium without pulsation. The drive system equipped with the rotor pump can operate at a higher rotational speed when the viscosity of the medium to be transported decreases, and the leakage amount increases, ensuring a constant output flow rate.
Sanitary Transfer Pump
All parts in contact with the material are made of stainless steel that meets hygienic standards. It is suitable for all sanitary and corrosion resistant applications and is widely used in food, beverage, pharmaceutical, chemical and other industries.
With Insulation Jacket
Depending on the needs of the different work spaces, an insulation jacket can be added to the rotor pump. This structure can ensure that the material which is easy to solidify at a low temperature state is kept at a constant temperature during the transportation process, and no condensation occurs.
Water Flushing Mechanical Seal
A mechanical seal structure with water flushing function can be provided to prevent material from condensing on the end face of the mechanical seal during the process of conveying high-viscosity materials, thereby affecting the normal operation of the equipment and ensuring the use of mechanical seals in harsh environments. life.
