GENERAL INFORMATION
Our pista grit separator model 05-054 is specially designed for the removal of sand present in the sewage waters to avoid the deposit of organic material. The sand deposited in the central hopper, is extracted by means of an air-lift.
CONSTRUCTION FEATURES
The grit separator consists of two steel blades with curved and angled profile, fixed to the central cylinder which rotates around the concentric air-lift pipe. The central control unit of the blades is composed of a coaxial / epicycloidal fast gearmotor. The whole system is completely oil-lubricated. The driving part is assembled on a robust steel plate for mounting on walkway. The airlift consists of a flanged pipe that ends in the tank bottom with a hydroextractor. The hydroextractor is a double-annular chamber, with special distribution holes. The lifting of the sands takes place through compressed air, which, by lightening the mixture inside the air-lift, creates the conditions for a suitable extraction of sand from the bottom of the tank. The machine is equipped with piping for washing pressure for cleaning operations with water.
