Improved piston pump for phytosanitary treatments rivers in agriculture

摘要

1.Bomba perfected piston for phytosanitary treatments in agriculture, characterized in that includes a collar material substantially resilient body formed in a guide piston movable mechanically and rigid material, so that the friction between them is greatly reduced. 2.Bomba perfected for phytosanitary treatments in agriculture piston, all according to the first claim, characterized in that also includes a sealing adaptation menso constituted by two collectors respectively, intake valves and two pressure and also inlet and pressure impeller -, respectively, and mounted on the piston itself, so obtained, in the operation of the pump suction double activity is achieved. 3.Bomba piston for improved agricultural pesticide treatments.
