- The construction of pumps for food industry is such that easy cleaning is possible. The pump may be disassembled and assembled quickly. They are used in applications, where media pumped are changed often, what makes that the pump must often be cleaned, sterilised or disinfected. Pump steel parts in contact with media are made of chromium nickel steel and polished. The stator is made of rubber allowed for contact with food.
Certificate by National Institute of Hygiene declares that rubber used to produce stator for pumps type PSRS can be in contact with food products.
