Motor Driven Metering Pumps

Direct Diaphragm (0 to 500 l/h)

Direct Piston (500 to 1.500 l/h)

Direct Diaphragm – D Series

The dosing pump has a reduction mechanism and an electric motor mounted vertically in accordance with the specifications UNEL-MEC (possibility of anti-explosive motor).

The flow is regulated by an endless screw from 0 to 100% of its capacity (running or stopped).

Suitable for cases in which:

  • The liquid to be dosed contains small suspended solids
  • If the solution is toxic
  • When high pressure is not required

With possibility of motor with built-in digital display, allowing:

  • Manual control (10 to 100%)
  • Analog control by 4-20 mA signal
  • Batch: The pump can be programmed to operate for a certain period of time
  • Level control: A level sensor can be connected
  • Diaphragm rupture detector: In case of failure in the diaphragm, the pump operation stops and an alarm goes off
  • Remote alarm: Alarm relay
