Piston pump P

for chemicalswith electric motorstationary

The metering pumps P series are driven by an electric motor, the dosage takes place thanks to a piston. The P series pumps make their robustness and reliability their main characteristic • Valves: PVC pump head – double ball valves, except for piston Φ95 with single ball - SS316L – Single ball, except for piston Φ16 and Φ30 with double balls • Frequency: 60, 103 and 120 strokes/min at 50Hz - 72 and 122 strokes/min at 60Hz • 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: PVC or PVDF • Piston in SS316 or Ceramic • Piston seals NBR, FPM or EPDM • Protection degree: On request ST-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)
