AT1 Red Dosing Pump Series
Our AT1 red dosing pump series are high pressure dosing pumps, designed to meter a small amount of chemical precisely into a process. The high pressure dosing pump range are rated for continual operation and are specifically designed for use with standard and concentrated chemical reagents.
The AT1 series of red dosing pump are suitable for either surface mounting using the supplied wall mounting bracket or for foot mounting applications using the optional foot mounting stand.
AT1 High Pressure Dosing Pump - Control Options
Within the AT1 range we offer a number of different control options as listed below:-
The AT1-BL high pressure dosing pump range are continuous flow rate dosing pumps, where the output flow rate can be manually adjusted. The manual control can be operated across 0 - 100% of the rated output and in the Low flow mode allows for precision control of the pump across 0 - 20% of the output, ideal for low volume or high pressure applications where the chemical reagent has to be precisely metered into a process.
The AT1-BL high pressure dosing pump range are continuous flow rate dosing pumps, where the output flow rate can be manually adjusted. The manual control can be operated across 0 - 100% of the rated output and in the Low flow mode. This allows for precision control of the pump across 0 - 20% of the output, designed primarily for low volume or high pressure applications.
The AT1-BL includes an input from a volt free contact which can be connected to an optional float switch to stop the pump when a low chemical level is present.
The AT1-AM high pressure dosing pump range are proportional control dosing pumps to a Pulsed Input or a 4-20mA input. In these models the flow rate or speed of the dosing pump is automatically adjusted as the number of pulses coming into the pump changes or as the 4-20mA input from a control instrument changes. Ideal for chlorine dosing or for process control applications where the amount of chemical reagent has to be precisely meter, such as pH correction.
The AT1-AM also includes a volt free input for use with an optional float switch, a flow verification input and an alarm relay output.
The AT1-MT high pressure dosing pump range are microprocessor controlled dosing pumps which can work as manually adjustable dosing pumps, proportional to a Pulsed Input; proportional to a 4-20mA input or volt free start signal. The AT1-MT microprocessor controlled pumps offer sophisticated control methodology including proportional control which can be configured in the pump software for PPM dosing. This allows a set PPM rate to be achieved (perfect for chlorine dosing), batch dosing, which transfers a set volume of chemical reagent, and timer dosing, which allows the pump to run for a set period of time.
The AT1-MT includes an input for use with an optional float switch, flow verification input, remote start / stop input (which can be used with a flow sensor), and an alarm relay output.

AT1 Dosing Pump Series
AT1-BX
The AT1-BX dosing pump series are manually adjustable constant flow rate dosing pumps with a maximum output from 0 - 2.0 Litres per hour and maximum pressure up to 20.0 Bar.
Using the front mounted potentiometer, the AT1-BX can be adjusted from 0 - 100% of the rated output. Using the special low dosing mode the range can be restricted to 0 -20% of the rated output to ensure precision dosing even at low flow rates.
The AT1-BX is powered from a switch mode power supply to operate from 100 - 240 VAC 50 / 60Hz.
AT1-BL
The AT1-BL dosing pump series are manually adjustable constant flow rate dosing pumps with a maximum output from 0 - 2.0 Litres per hour and maximum pressure up to 20.0 Bar.
Using the front mounted potentiometer the AT1-BL can be adjusted from 0 - 100% of the rated output. Using the special low dosing mode the range can be restricted to 0 -20% of the rated output to ensure precision dosing even at low flow rates.
The AT1-BL also has a volt free contact input which can connected to a low level float switch to stop the pump when there is a low chemical level present.
The AT1-BL is powered from a switch mode power supply to operate from 100 - 240 VAC 50 / 60Hz.
AT1-AM
The AT1-AM dosing pump series have a maximum output from 0 - 2.0 Litres per hour and maximum pressure up to 20.0 Bar and can operate at either a constant flow rate which is manually adjustable, dose proportional to a pulsed input signal or dose proportional to a 4-20mA input signal.
When dosing proportional to a 4-20mA signal the maximum output can be configured in the pump. When dosing proportional to a pulsed input (from a water meter / pH controller) the AT1-AM allows the user to multiply or divide the number of pulses if required, ensuring the right amount of chemical reagent is dosed into the process.
The AT1-AM includes a number of additional inputs and outputs including a volt free signal input for low-level, flow verification signal input, and an alarm relay output.
The AT1-AM is powered from a switch mode power supply to operate from 100 - 240 VAC 50 / 60Hz.
AT1-MT
The AT1-MT dosing pump series is a microprocessor operated dosing pump with maximum output from 0 - 2.0 Litres per hour and maximum pressure up to 20.0 Bar and can operate in the following modes:-

- Dose proportional to a 4-20mA input signal.
- Maintain a set PPM rate of chemical proportional to a pulsed input
- Batch a desired amount of chemical into a process.
- Operate for a specified time for timed dosing
All options user selectable using the simple on screen programming menu and all the dosing options are fully configurable including multiplication and division of a pulsed signal, and full 4-20mA control including inversion & scaling.
The AT1-MT includes a number of additional inputs and outputs including a volt free signal input for low-level, flow verification signal input, a volt free remote control input to start / stop the pump and an alarm relay output.
