Motor Driven Dosing Pumps
 Diaphragm Metering Pumps
Motor Driven Metering pumps belong to the family of alternating volumetric pumps these pumps are recommended when high performances and accuracy are required.
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%
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%
  MAIN FEATURES
  MOTORS CHARACTERISTICS
Mechanical actuated diaphragm metering pumps are designed for dosing liquids free or with very small suspended solid particles.
Mechanical diaphragm type pumps are suitable when:
> Zero leakage is essential > Pumped liquid contains suspended solids particles
 The pump comprises of four basic sections: motor drive, gearbox, pump head and valves.
Pump Head:
 pumping action is performed by a push rod pushing the diaphragm, which has a reciprocating movement within the pump head.
 All parts are in direct contact with the liquid being metered.
 The sealing effect is achieved by rings of material suited to the liquid being handled.

 Pump Adjustment & Control

 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 of percentage adjustment knob which regulates the micrometer screw. The pump will constantly perform the dosing rate according to flow selected. By connecting an inverter On/Off the pump output is adjusted according to the external signal recieved.
Inverter to control pump flow via remote control from external input signal 4?20 mA, upon request.
