AT1-BX

High Pressure Dosing Pump

High pressure dosing pump AT1-BX

The AT1-BX is a high pressure dosing pump with a manually adjustable output from 0 - 100% of the full range.


AT1-BX High Pressure Dosing Pump Introduction

The AT1-BX is a high pressure solenoid dosing pump designed to precisely meter a small amount of chemical into a process. The AT1-BX delivers a constant flow rate which is manually adjustable using the front mounted potentiometer.

Ideal for applications where a very small amount of chemical reagent is to be dosed into an application, the AT1-BX includes a special low 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 AT1-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 AT1-BX is a simple and reliable dosing pump for high pressure dosing applications.

The AT1-BX is powered from a switch mode power supply, suitable for a mains supply of 100 - 240 VAC 50hz or 60Hz.


AT1-BX Dosing Pump Outputs

The AT1-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)
AT1-BX-20-015 0 - 1.5 20.0 120 0.21 4 x 6 / 7 15
AT1-BX-18-02 0 - 2.0 18.0 120 0.28 4 x 6 / 7 15

AT1-BX Method of Operation

The AT1-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 AT1-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 which can be selected using the selector switch.  This restricts the output to a maximum of 20% of the rated output and the user can increase or decrease the flow rate anywhere on the 0 - 20% range using the front mounted potentiometer (across a range of 0 - 100%).

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 AT1-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 AT1-BX is designed to IP65 specification, making it suitable for indoor or outdoor operation and 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.


AT1-BX Wetted Parts / Liquid End

The AT1-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 AT1-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.

  • Head Material

    The wetted parts of the pump head are manufactured in PVC or PVDF.

  • Double ball valves

    Double union ball valves are manufactured in PVC or PVDF with Ceramic or PTFE balls 

  • Diaphragm

    The diaphragm is manufactured in PTFE.

  • Injection Valve

    The injection valves are manufactured in PVC or PVDF

  • Foot Valve & Strainer Valve

    The foot valve and strainer assembly is manufactured in PVC or PVDF

  • Seals & O-Rings

An optional foot mounting bracket can be included for no additional charge, if requested.


AT1-BX Features & Benefits

The AT1-BX is a robust, reliable and accurate chemical dosing pump, designed for high pressure operation or where a small amount of chemical reagent is required in a process. 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 AT1-BX is fitted with wetted parts which are suitable for many chemical reagents.  The model has 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 AT1-BX is suitable for mounting outside.

The AT1-BX is available as the following model types:-

  • AT1-BX-20-015 for an output flow rate of 1.5 Litres / Hour at 20 Bar pressure
  • AT1-BX-18-02 for an output flow rate of 2.0 Litres / Hour at 18 Bar pressure

The AT1-BX series are powered from a switch mode power supply and operates with a mains supply of 100 - 240 VAC at 50Hz / 60Hz, making the AT1-BX suitable for export markets.

As part of our red dosing pump range, the AT1-BX is rated hot for continuous dosing duty and the pump is designed to provide a long trouble free life giving accurate chemical dosing.
