AR30 pump 20mm 3 bolt flange
Semi-hydraulic two-diaphragm pump, for use in the semi-professional agricultural sectors. Can be 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 Resin-coated aluminium, and AISI 303/304. Diaphragms in NBR have now been upgraded to Bueflex for superior performance and long life. 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. Oil drainage stopper. Pistons with ring for a more efficient “oil cushion” system to protect the diaphragm.
New-design diaphragm cut-out system to prevent contact tearing even in heavy-duty operating conditions.
