High Flow Rate Dosing Pump
The AT4-BX is a high flow rate dosing pump with an output up to 60.0 litres per hour. Outputs are manually adjustable to suit a wide range of dosing applications.
AT4-BX High Flow Rate Dosing Pump Introduction
The AT4-BX is a high flow rate chemical dosing pump designed to precisely dose chemical reagents into a process. The AT4-BX delivers a constant flow rate which is manually adjustable using the front mounted potentiometer.
The AT4-BX chemical dosing pump is designed to deliver a larger volume of chemical reagent for larger volumes in the water treatment, wastewater treatment, effluent treatment and process control applications. The AT4-BX is suitable for applications where concentrated chemical reagents are used with wetted parts to suit. The AT4-BX also includes a special low dosing mode although another of our manually adjustable dosing pumps may be a better fit for low dosing applications.
The AT4-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 AT4-BX is a simple and reliable dosing pump for general applications.
The AT4-BX is powered from a switch mode power supply, suitable for a mains supply of 100 - 240 VAC 50hz or 60Hz.
AT4-BX Dosing Pump Outputs
The AT4-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)|
|AT4-BX-05-20||0 - 20.0||5.0||300||1.11||8 x 12||25|
|AT4-BX-03-30||0 - 30.0||3.0||300||1.66||8 x 12||25|
|AT4-BX-02-40||0 - 40.0||2.0||300||2.22||8 x 12||25|
|AT4-BX-01-60||0 - 60.0||0.5||300||3.33||8 x 12||25|
AT4-BX Method of Operation
The AT4-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 AT4-BX will begin metering chemical into a process at a desired rate, using the front mounted potentiometer.
The AT4-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. If you're looking for a lower output dosing pump, it may be advisable to look at our other manually adjustable dosing pumps.
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 AT4-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, to ensure that the pump is ready to accurately dose chemical into a process.
Designed to IP65 specification, the AT4-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.
AT4-BX Wetted Parts / Liquid End
The AT4-BX is designed as a high flow rate chemical metering pump for industrial usage and as such has wetted parts developed specifically for chemical handling.
As standard the AT4-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 AT4-BX?
The AT4-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

An optional foot mounting bracket can be included for no additional charge, if requested.
AT4-BX Features & Benefits
The AT4-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 AT4-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 AT4-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 AT4-BX is suitable for mounting outside.
The AT4-BX is available as the following model types:-
- AT4-BX-05-20 for an output flow rate of 20.0 Litres / Hour at 5.0 Bar pressure
- AT4-BX-03-30 for an output flow rate of 30.0 Litres / Hour at 3.0 Bar pressure
- AT4-BX-02-40 for an output flow rate of 40.0 Litres / Hour at 2.0 Bar pressure
- AT4-BX-01-60 for an output flow rate of 60.0 Litres / Hour at 0.5 Bar pressure
As the AT4-BX series are powered from a switch mode power supply, able to accept a mains supply of 100 - 240 VAC at 50Hz / 60Hz, ensuring that the AT4-BX is compatible with export markets.
As part of our Red Dosing Pump range, the AT4-BX is rated hot for continuous dosing duty, and the pump is designed to provide a long trouble free life of precision chemical dosing.
