Compact mechanical diaphragm dosing pumps with spring return mechanism. A high torque electric motor drives forward stroke via a worm gear and eccentric mechanism. The robust gearbox reduction systems ensure high performances giving reliability and repeatable performance. Fluid displacement by single piece PTFE diaphragm connected directly to the gearbox return rod.
Features: Flow capacities of 10 to 123 l/h (2,64-32,50 GPH) at 50 Hz - 12 a148 l/h (3,17-39,00 GPH) at 60 Hz • Pressure up to 14 bar (203 PSI) • Strokes: 60-60 -120-120-120 at 50 Hz - 72-72-144-144-144 at 60 Hz • Stroke lengths: 2,6-3,1-4 mm - 1”-1,2”-1,6” • Motor Power range: 0,18 kW.
