Dosing Pumps
Metering Pumps
Diaphragm Dosing Pumps

Applications for our red dosing pumps or chemical metering pumps are numerous. To meet the applications we offer chemical dosing pumps, which will mount on a flat vertical surface such as a wall and will draw the chemical from a chemical carboy.

The wall mounted dosing pumps are available in 2 different types.

We have the AWE HY Series Metering Pump and the more powerful AWE AT Series Metering Pump that offers dosing up to 60 Litres per hour and pressures of up to 20 Bar

Traditionally our customers associate us with Water, Waste Water (Effluent) Treatment and pH or Redox control. However, every waste water treatment plant or process that uses the water produces waste water. In that process are many applications for accurately metering the required chemical treatment additives to ensure efficient and cost effective production.

Red Dosing Pump

AWE have been supplying red dosing pumps since 1994 and have a large installed base of this type of metering pump in the UK and throughout the world

The current range of Red Dosing Pumps (RDP) are as follows:

HY-Series Dosing Pump

AWE HYBX Red Dosing Pump

The HY-Series is our latest series of diaphragm dosing pumps. They have a fixed stroke length and the output is controlled by adjusting the pump frequency or number of strokes per minute the pump solenoid makes.

The HY Series of metering pump can be found in a wide variety of industrial applications including:

  • Detergent Dosing
  • Cooling Tower Biocide Dosing
  • Inhibitor Dosing
  • Swimming Pool Treatment
  • Chemical Dosing

In addition to controlling the HY-BC Dosing Pump from a pulse counter - The metering pump can also take an input from a volt free contact which can be used as a low level cut out. The HY-BC Red Dosing Pump is also fitted with a switch mode power supply ensuring that it can run from 100 VAC to 240 VAC at 50Hz / 60 HZ.

AWE HY-AM Metering Pump

4-20mA input Dosing Pump - AWE HYAM

The analogue AWE HY-AM Red Dosing Pump has selectable control from either manual control through the top mounted potentiometer which features on all our AWE HY series red dosing pumps, or external pacing through a 4-20mA analogue control signal.

The HY-AM Red Dosing Pump also has fitted power on LED, Low Level Input and switch mode power supply from 100 VAC to 240 VAC at 50Hz or 60 HZ.

  • 0-20% of the output

This allows for greater accuracy of setting the output without the complication of stroke adjustment

When selecting Auto Control this can be from either

  • An external pacing input from a volt free contact closure with the ability to either multiply or divide the number of strokes the pump makes per input pulse.
  • Alternatively the dosing pump can be controlled by a 4-20mA control signal which can control the pump proportional to the magnitude of the current input

As with all the AWE AT Series of metering pumps -: the PVC / PVDF head is fitted with a valve to aid priming of the pump.
