FP 430 Ex S-41/38 FOOD
The FP 430 Ex S-41/38 FOOD pump with a mechanical seal is suitable for pumping
liquids which tend to crystallise and harden. The liquid does not penetrate into the
inner tube. The shaft therefore only contacts the liquid in the rotor area.
The mechanical seal seals the inner tube towards the fluid. In this way, the seal
prevents the fluid from getting into the inner tube. The shaft is in contact with the
fluid only in the area of the impeller.
