Self-priming hand pump for suction from open containers or from streams and ponds. Perfect for use in construction and for industrial painting. It can also be used for the suction and movement of non-potable water to purification units by osmosis. It consists of a pumping unit, operated by a steel lever, which sucks the liquid from a container or stream, and sends it under pressure inside a large accumulation chamber which ensures a strong working autonomy. The brass pumping system is housed in a practical painted steel stand which raises it from the ground and facilitate an ergonomic pumping position. A suction pipe with filter, a lance with LA6001 lever handle completely in brass, 50 cm extension, fixed pattern jet are included.
