Abstract (en)
The pump is normally used for pumping fluid products containing solid parts, and comprises a piston (1), slidable internally of a chamber (1a), which piston (1) introduces the product into the chamber (1a) by aspirating the product through an inlet mouth (2) and expels the product from the chamber (1a) through an outlet mouth (4); the chamber (1a) develops along a longitudinal axis; the inlet mouth (2) and the outlet mouth (4) have axes which are perpendicular to the chamber (1a) axis ; the piston (1) is arranged coaxially to the chamber (1a) axis at an end of the chamber (1a) and slides between two extreme positions in such a way that it never covers the inlet mouth (2) and the outlet mouth (4) holes.
