Description

Semi-hydraulic two-diaphragm pump, for use in the gardening or semi-professional agricultural sectors. Trolley-mounted in combination with electric motors or internal combustion engines for gardening, and small sprayers for medium-pressure pesticide treatments in gardens, greenhouses, orchards or vineyards. Parts in contact with pumped liquids in anodized aluminium, and AISI 303/304. Diaphragms in BlueFlex™.  Seals in NBR. Die-cast casing with oil-immersed mechanism and clear plastic tank for visual level checking. Fitted with air-hydraulic damper for smoother operation and less hammer effect in the delivery circuit. Pistons with ring for a more efficient “oil cushion” system to protect the diaphragm. Metal fasteners with galvanised finish. Reduction gearboxes for internal combustion engines.
