What to consider when buying lobe pump with sanitary grade?

Lobe pump with sanitary grade is a type of positive displacement pump that can handle fluids of virtually any viscosity, especially those with high solids content or sensitive particles. Lobe pumps are widely used in hygienic and sanitary applications, such as food, beverage, pharmaceutical, cosmetic and chemical industries. But how do you choose a lobe pump with sanitary grade that meets your needs? Here are some factors to consider.

What is lobe pump with sanitary grade?

High hygiene level rotor pump is a lobe pump that meets the highest standards of hygiene and cleanliness. A lobe pump consists of two rotors that rotate synchronously in a pump casing, creating chambers that trap and move the fluid from the inlet to the outlet. The rotors can have different shapes, such as tri-lobe or bi-wing, depending on the application and the fluid characteristics.

What are the advantages of lobe pump with sanitary grade?

1. It can handle fluids of virtually any viscosity, from water to paste, without affecting the flow rate or the pressure.

2. It can handle fluids with high solids content or sensitive particles, such as slurries, sausages, chocolate or yogurt, without damaging them or causing blockages.

3. It can operate in both directions, allowing reverse flow or emptying of the pipes.

4. It can provide a pulsation-free and continuous flow, which ensures a smooth and uniform product quality.

5. It can operate at low rotation speeds and high output torques, which reduces wear and maintenance costs.

How to choose a lobe pump with sanitary grade that meets your needs?

1. The flow rate and the pressure that you need to achieve. These depend on the size of the pump body, the speed of the rotors and the design of the chambers. You can use performance curves to find the optimal combination for your application.

2. The viscosity and the solids content of your fluid. These affect the choice of the rotor shape and size, as well as the inlet and outlet connections. You should choose a rotor that can create enough suction to feed your fluid and avoid cavitation. You should also choose an inlet that is large enough to accommodate your fluid without causing excessive pressure drop or turbulence.

3. The temperature and the pH of your fluid. These affect the choice of the material and the coating of the rotors and the pump casing, as well as the type of seal. You should choose a material and a coating that can resist corrosion and abrasion from your fluid. You should also choose a seal that can withstand high temperatures and pressures without compromising hygiene.

In conclusion, sanitary grade rotary lobe pump is a versatile and reliable pump that can handle fluids of virtually any viscosity in hygienic and sanitary applications. However, you should consider some factors related to your application and your fluid characteristics when choosing a lobe pump with sanitary grade that meets your needs.
