Chemical pump D

with electric motordiaphragmstationary

The metering pumps D series are driven by an electric motor, the dosage takes place thanks to a NBR/PTFE (material in contact with the liquid) diaphragm. The D series pumps make their robustness and reliability their main characteristic. • Valves: Single ball with SS316L pump head - Double balls with PVC pump head • Frequency: 60, 103 and 120 strokes/min at 50Hz - 72 and 122 strokes/min at 60Hz • Diaphragm in NBR/PTFE - PTFE material in contact with the chemical • Die-cast aluminum housing protected by epoxy/antiacid paint • Pump Head: PVC, SS316L or PVDF • Balls: ceramic or SS316L • Ball seats FPM, EPDM or NBR • Valves seats in PVC or PVDF • IP55 protection degree • Insulation class: F On request D pumps series can be equipped with: Motorizations: • Without motor • UL/CSA motor certification • Single-phase motor • Self-ventilated motor • ATEX motor • Tropicalized motor Hydraulic: • NPT hydraulic connections • Larger dimensions valves Regulation and control by an external signal: • Electric actuator (automatic adjustment of piston “run” by a 4-20mA signal) • Inverter (automatic adjustment od motor speed by a 4-20mA signal)
