Model meaning: "RP" usually refers to the series model of the rotary pump. "25" may indicate that the inlet and outlet pipe diameters of the pump are 25mm, and "8" generally represents that the rated flow rate of the pump is around 8m³/h. Different manufacturers may have slight differences, but generally follow such a naming rule.
Performance parameters:
Flow rate: 0.85 - 8m³/h.
Recommended rotational speed: 40 - 450rpm.
Ultimate pressure: 1.6MPa.
Viscosity range: 1 - 1000000CP.
Power: 2.2 - 11kW.
Inlet and outlet pipe diameters: 63.5mm.
Structural features:
Pump body: Generally made of materials that meet hygienic standards such as 304/316 stainless steel, it has good corrosion resistance and hygienic performance. With a smooth surface, it is easy to clean and has no dead corners for hygiene, which can prevent the growth of bacteria.
Rotor: Commonly in the shape of a three-lobe rotor, etc. Its surface is smooth, and the clearance between it and the pump body is extremely small, ensuring efficient conveyance and good sealing. The material is mostly stainless steel, which can ensure the safety and hygiene of contact with materials.
Shaft seal: Mechanical seals are mostly adopted, such as externally mounted dynamic and static ring mechanical seals. They have the advantages of good sealing performance and long service life. Moreover, they can be directly flushed with water, are resistant to high pressure, are not easy to wear, and have no leakage, which can effectively prevent material leakage and ensure hygiene and safety.
Transmission system: It usually consists of components such as motors and couplings. The motor provides power, and the coupling transmits the power of the motor to the rotor to ensure the synchronous rotation of the rotor. According to different driving forms, such as motor + continuously variable transmission, motor + fixed ratio reducer, variable frequency motor + frequency converter, etc., different speed regulation effects and performance characteristics can be achieved.
Application fields:
Food industry: It can be used to transport various food materials such as milk, yogurt, cream, fruit juice, jam, honey, syrup, chocolate, meat sauces, etc., ensuring the hygiene and quality of food.
Pharmaceutical industry: It is widely used to transport various drugs, pharmaceuticals, vaccines, blood products, ointments, emulsions, etc., meeting the high hygienic standards and precise metering requirements in the pharmaceutical production process.
Cosmetics industry: It can transport raw materials and finished products of cosmetics such as face creams, emulsions, shampoos, body washes, perfumes, etc., ensuring the quality and stability of products.
Chemical industry: It is applicable to transport various chemical materials with high viscosity, corrosiveness, flammability and explosiveness, such as coatings, inks, glues, resins, lubricating oils, etc.
Advantages:
High hygienic safety: Its material and structural design make it meet the strict hygienic requirements of industries such as food and medicine, which can effectively avoid material pollution.
Good conveying performance: It can transport materials with high viscosity, containing solid particles or being shear-sensitive. Moreover, the conveying process is stable, the flow rate is stable, and it causes little damage to the materials, and can maintain the original characteristics and structure of the materials.
Strong self-priming ability: It has a certain self-priming performance and can automatically suck in materials without the need for external auxiliary devices. It can adapt to various complex installation environments and technological processes.
Small shearing effect: Its working principle determines that it has a relatively small shearing effect on materials, and it is especially suitable for transporting fragile and shear-sensitive materials.
Adjustable flow rate: Through variable frequency speed regulation or other speed regulation methods, the conveying flow rate can be flexibly adjusted according to the actual production needs, with remarkable energy-saving effects and a reduction in production costs.
Excellent sealing: Advanced sealing technologies are adopted to ensure that there is no leakage during the operation of the pump, prevent material waste and environmental pollution, and at the same time reduce the maintenance workload and costs.
