Food-grade hygienic progressive cavity pumps are used in the food, pharmaceutical, cosmetic and chemical industries for hygienic applications and optimal cleaning. Important features include continuous, pressure-stabilized, gentle, low-pulsation pumping and metering proportional to speed. The overflow material is stainless steel and the block pumps with flange drive are particularly compact and economical to operate.

Flow range: 0.8 m³/h – 60 m³/h

Maximum pressure: 1.2 Mpa

Overcurrent material: 304, 316

The compact design of the AOBL food and hygiene progressive cavity pumps provides optimal process characteristics for a wide range of food and hygiene applications. Due to the minimal pulsation and shear characteristics, they are also well suited for conveying sensitive foodstuffs.
