Sanitary rotary pumps are a type of sanitary pump, and their main difference lies in their specific streamline structure and design features, making them more suitable for use in industries with high hygiene requirements.
The characteristics of sanitary rotary pumps include:
Health and safety: The streamlined structure of the rotor and the inner cavity of the pump body are flat and smooth, without dead corners, effectively preventing materials from seeping into the gap between the shaft and the shaft hole. The components in contact with the material are made of stainless steel materials that meet hygiene standards, and the sealing rubber is made of hygiene grade rubber. There are mechanical seals and oil seals between the pump body and the gearbox, which prevent oil stains from penetrating or splashing into the pump chamber, ensuring the hygienic and safe transportation of the medium.
Long service life: During use, there is no hard collision or metal friction between the rotors and between the rotors and the pump chamber of the sanitary grade rotary pump, which improves the service life. Due to high manufacturing precision, minimal vibration, and smooth operation, the service life of the seals also increases accordingly.
Wide application range: It has low shear force on transport media, can transport media with a wide viscosity range, and can transport fluids with viscosity up to 2 million CP. Due to the reasonable gap design between the two rotors, it is possible to safely transport suspensions, solid particles, and easily crystallizable fluids in the conveying medium through the gap. After configuring the frequency converter, the flow rate can be adjusted and it can be used as a general metering pump. The mobile pump can suck various barrel materials, with a suction vacuum degree of -0.08MPa.
Efficient, energy-saving and environmentally friendly: Practice has proven that the power consumption of sanitary rotary pumps is equivalent to 50% to 70% of similar pumps, saving social energy. The clearance between the rotor and the pump chamber is small, so even when conveying low viscosity fluids, the generated reflux is also small, making the pump's flow more stable, efficient, and suction better.
In contrast, sanitary pumps may be a broader category that includes different types of pumps, and sanitary rotary pumps are one of the pumps with specific design and application characteristics. Sanitary rotary pumps are particularly suitable for use in fluid handling processes that require high hygiene, such as food and beverage, pharmaceutical, and other industries, due to their streamlined structure and the use of sanitary grade materials
