Piston-Diaphragm Pump

Assembly

The spray pump: pistons in an oil bath push on rubber diaphragms that move the liquid. It delivers about 140 L/min at up to 50 bar, enough to feed the nozzles and the tank agitator at once, and tolerates abrasive and corrosive mixes. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
