Motor Driven Dosing Pumps

Motor Driven Metering pumps belong to the family of alternating volumetric pumps. Motor dosing pumps are recommended when high performances are required.

MAIN FEATURES
  • Gearbox in cast aluminium protected with Epoxy paint
  • Flow rate adjustment via stroke length from 0-100% whilst in operation or at rest
  • Motor/gearbox are coupled by means of flexible coupling, thus increasing transmission life
  • Standard power supply: 230/400 Vac 50 Hz / 275/480 Vac 60 Hz; 3 phase,+/-10%
MOTORS CHARACTERISTICS
  • Standard MULTI FREQUENCE/VOLTAGE: 230-400Vac 50Hz • 275-480Vac 60Hz / 3phase / ±10%
  • Conform with IP55 protection. Isolation class F, others available upon request
  • Motors are TEFC vertically mounted, B14 type, ?1400 rpm

Other power supply upon request:

  • 230 Vac 1 phase 50 Hz or 230 Vac 60 Hz (*) • 110 Vac 1 phase 50 Hz or 60 Hz (*)

(*) NOTE: at 60 Hz frequency, motor speed and thus stroke rates and flow rates increase by approx. 20%

MECHANICAL ACTUATED DIAPHRAGM METERING PUMPS

PUMP ADJUSTMENT CONTROL

REGOLAZIONE PORTATA-CORSA

Constant / ON-OFF mode: knowing the amount of additive to inject, pump flow rate (injected single stroke volume) is adjusted via piston strokes length by means a knob which regulates the micrometer screw. The pump will constantly perform the dosing operation according to flow rate by the selected frequency. Connected to a Remote On/Off equipment, the pump will start and stop operations according to the external contact.

REGOLAZIONE PORTATA-CORSA

Inverter to control pump flow via remote control from external input signal 4?20 mA, upon request.

REGOLAZIONE PORTATA-CORSA

Servomotor 4÷20mA or 0?10Vdc for flow automatic control via stroke length control, upon request.

REGOLAZIONE PORTATA-CORSA

Controller to manage external contacts (e.g. water meter) synchronizing the activation time of output relay: recommended for proportional dosing (dividing mode) with motor dosing pumps.
