Constant Flow Rate Dosing Pump
The AT2-BX is a constant flow rate chemical dosing pump dosing with a manually adjustable output which can be set from 0 - 100% of the full range.
AT2-BX Constant Flow Rate Dosing Pump Introduction
The AT2-BX is a chemical dosing pump designed to precisely dose chemical reagents into a process. The AT2-BX delivers a constant flow rate which is manually adjustable using the front mounted potentiometer.
Ideal for most general dosing applications even where concentrated chemical reagents are used, the AT2-BX also includes a special low dosing, dosing mode. This restricts the maximum output of the pump to 20% of the rated output and gives the user full control from 0 - 100% of the restricted output.
The AT2-BX can be attached to a flat vertical surface for surface mounting installation or used with the optional foot-mounting bracket for foot mounting applications. Designed primarily for water treatment, waste-water treatment, effluent treatment and process control, the AT2-BX is a simple and reliable dosing pump for general applications.
The AT2-BX is powered from a switch mode power supply, suitable for a mains supply of 100 - 240 VAC 50hz or 60Hz.
AT2-BX Dosing Pump Outputs
The AT2-BX dosing pump series are available with the following outputs:-
|Model Number*||Output (Litres / Hour)||Pressure (Bar)||Speed (Strokes / Min)||Output (mls / stroke)||Hose Size (mm)||Power (Watts)|
|AT2-BX-12-03||0 - 3.0||12.0||160||0.31||4 x 6||15|
|AT2-BX-10-04||0 - 4.0||10.0||160||0.42||4 x 6||15|
|AT2-BX-08-05||0 - 5.0||8.0||160||0.52||4 x 6||15|
|AT2-BX-02-08||0 - 8.0||2.0||160||0.83||4 x 6||15|
AT2-BX Method of Operation
The AT2-BX is incredibly simple to operate. The pump has an On/Off toggle switch to locally control the pump and with power applied to the dosing pump and the switch turned to on, the AT2-BX will begin metering chemical into a process at a desired rate using the front mounted potentiometer.
For low chemical dosing modes (below 20% of the rated output), the pump has a special low dosing mode accessed using the selector switch. When the low dosing mode is enabled, the pumps output can be adjusted across 0 - 20% of the output using the front mounted potentiometer.
The pump can either be directly connected to a mains supply voltage or switched on using the relay output from a piece of control equipment, such as a pH Controller, cooling water controller or other piece of process control equipment.
With a fixed stroke length, the flow rate of the pump can be reduced using the front mounted potentiometer which adjusts the stroke frequency and therefore ensures precision control of the flow rate.
Priming the dosing pump couldn't be simpler - the AT2-BX has an adjustable bleed valve located on the pump head and using the supplied tubing is connected back to the chemical container or chemical origin making the priming process as simple as possible.
The AT2-BX is designed to IP65 specification making it suitable for indoor or outdoor operation. It can be foot mounted or surface mounted to a flat vertical surface. Power is via a switch mode power supply, meaning that an AC supply voltage of 100 - 240 Volts at 50Hz / 60Hz can be used to power the pump.
AT2-BX Wetted Parts / Liquid End
The AT2-BX is designed as a chemical metering pump for industrial usage and as such has wetted parts developed specifically for chemical handling.
As standard the AT2-BX is available with a liquid end manufactured in either PVC or PVDF, with Ceramic or PTFE balls and a PTFE diaphragm. The seals and O-rings are available in either Viton (© DuPont / Chemours) or EPDM with PTFE O-rings available as an option.
Our chemical compatibility database can be used to check the wetted parts. Please don't hesitate to get in touch if you are unsure.

AT2-BX Features & Benefits
The AT2-BX is a robust, reliable and accurate chemical dosing pump designed for most general process control applications in the water treatment, effluent treatment or process control sectors. The AT2-BX is Ideal for either stand alone operation or integration with process control equipment where output control relays provide a control loop for process automation.
Designed specifically for chemical metering, the AT2-BX is fitted with wetted parts suitable for many chemical reagents, with a liquid end manufactured in PVC or PVDF, a PTFE diaphragm, Ceramic or PTFE balls and either Viton, EPDM or PTFE seals and O-rings. Designed to IP65 specifications, the AT2-BX is suitable for mounting outside.
The AT2-BX is available as the following model types:-
- AT2-BX-12-03 for an output flow rate of 3.0 Litres / Hour at 12 Bar pressure
- AT2-BX-10-04 for an output flow rate of 4.0 Litres / Hour at 10 Bar pressure
- AT2-BX-08-05 for an output flow rate of 5.0 Litres / Hour at 08 Bar pressure
- AT2-BX-02-08 for an output flow rate of 8.0 Litres / Hour at 02 Bar pressure
The AT2-BX series are powered from a switch mode power supply and can accept a mains supply of 100 - 240 VAC at 50Hz / 60Hz, making the AT2-BX is suitable for integration with process plant which is destined for export.
As part of our Red Dosing Pump range, the AT2-BX is rated hot for continuous dosing duty, and the pump is designed to provide a long trouble free life of precision chemical dosing.
