HIGH-PRESSURE DIAPHRAGM PUMP — COMET PUMP

APS31

APS 31 is Comet’s high-pressure diaphragm pump in the compact range, designed for those requiring high-pressure performance on small to medium-scale treatments. Dal Degan uses it in its atomizers and compact spraying units as the reference component for the balanced combination of flow rate, pressure, and compact dimensions. The pump features a two-diaphragm configuration in NBR (available on request in Desmopan® and Viton for specific chemical requirements), with all liquid-contact parts in anodized aluminum ensuring corrosion resistance and long-term durability. The pump is equipped with stainless steel suction and delivery valves, all positioned on the delivery side to allow quick inspection and simplify routine maintenance. Available on request are a pressure accumulator (to dampen flow pulsations) and PTO protection (for operator safety on the driveline). The pump is manufactured entirely in Italy by Comet, a world leader in agricultural spraying pumps.
