Manually Adjustable Dosing Pump
The AT3-BX is a manually adjustable dosing pump which is suitable for a wide range of dosing applications.
AT3-BX Manually Adjustable Dosing Pump Introduction
The AT3-BX is a chemical dosing pump designed to precisely dose chemical reagents into a process. The AT3-BX delivers a constant flow rate which is manually adjustable, using the front mounted potentiometer.
The AT3-BX chemical dosing pump is ideal for most applications, even where concentrated chemical reagents are used. The AT3-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 AT3-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, wastewater treatment, effluent treatment and process control, the AT3-BX is a simple and reliable dosing pump for general applications.
The AT3-BX is powered from a switch mode power supply, suitable for a mains supply of 100 - 240 V AC 50hz or 60Hz.
AT3-BX Dosing Pump Outputs
The AT3-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)|
|AT3-BX-16-07||0 - 7.0||16.0||300||0.39||4 x 6||25|
|AT3-BX-10-10||0 - 10.0||10.0||300||0.55||4 x 6||25|
|AT3-BX-08-14||0 - 14.0||8.0||300||0.78||4 x 6||25|
|AT3-BX-02-18||0 - 18.0||2.0||300||0.89||4 x 6||25|
AT3-BX Method of Operation
The AT3-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 AT3-BX will begin metering chemical into a process at a desired rate, using the front mounted potentiometer.
The AT3-BX also includes a selector switch which allows the metering pump to be entered into low dosing mode. The low dosing mode restricts the output to a maximum of 20% of the pumps rated output. The use can then finely set the pumps output from a range of 0 - 20% 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 AT3-BX has an adjustable bleed valve located on the pump head and using the supplied tubing, the pump can be primed by allowing the chemical to circulate through the pump head. This ensures that the pump is ready to accurately dose chemical into a process.
Designed to IP65 specification, the AT3-BX is suitable for indoor or outdoor operation and 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.
AT3-BX Wetted Parts / Liquid End
The AT3-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 AT3-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.
What's in the box with the AT3-BX?
The AT3-BX is supplied complete with everything required to begin metering chemical reagents into a process.
Supplied with the dosing pump itself are:-
- Injection Valve with 3/8" and 1/2" BSP male threaded connections
- Foot-valve & Strainer assembly
- 1 metre of discharge tubing
- 2 metres of suction / bleed tubing

An optional foot mounting bracket can be included for no additional charge, if requested.
AT3-BX Features & Benefits
The AT3-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 AT3-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 AT3-BX is fitted with wetted parts which are 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 specification, the AT3-BX is suitable for mounting outside.
The AT3-BX is available as the following model types:-
- AT3-BX-16-07 for an output flow rate of 7.0 Litres / Hour at 16 Bar pressure
- AT3-BX-10-10 for an output flow rate of 10.0 Litres / Hour at 10 Bar pressure
- AT3-BX-08-14 for an output flow rate of 14.0 Litres / Hour at 08 Bar pressure
- AT3-BX-02-18 for an output flow rate of 18.0 Litres / Hour at 02 Bar pressure
As the AT3-BX series are powered from a switch mode power supply they are able to accept a mains supply of 100 - 240 VAC at 50Hz / 60Hz ensuring that the AT3-BX is compatible with export markets.
As part of our Red Dosing Pump range, the AT3-BX is rated hot for continuous dosing duty, and the pump is designed to provide a long trouble free life of precision chemical dosing.
