Pump Specifications
 
Outputs to 20L/Hr with 20% and 100% frequency adjustment

Reliable and robust design including LED frequency indication

Keypad output selection provides two dosing output ranges
 
Manual stroke length available for precise dosing control

Manual bleed with hose connection for chemical priming

Optional low level with level probe connected to footfilter

Supplied with footfilter injection fitting installation kit

Dosing head options Antigasing-PVC-PVDF-PTFE

Tank mounting dosing pumps for constant operation with frequency and stroke length adjustments covering a full spectrum of dosing outputs, the electronic components and mechanical parts provide a very robust designed pump with consistant performance and years of trouble free service.
Normally controlled using a instrument to power the pump they are designed to dose a precise volume of chemical into a pipeline or tank, occasionally when aggressive chemicals are being dosed alternative dosing heads and fitting are required for to ensure the integrity of the pumps performance.

Multifunction pump with proportional and seven day timer

Manual bleed with hose connection for chemical priming

Optional low level with level probe connected to footfilter

Supplied with footfilter injection fitting installation kit

Dosing head options antigasing--PVC-PVDF-PTFE

Digital dosing pumps covering a full spectrum of dosing outputs in a polypropylene housing with stoke length adjustment to give additional control, alternative heads and fittings are available for aggressive chemicals to ensure years of trouble free service. Pumps can be programmed in proportional or 420mA modes alternatively dosing using the internal timer program, chemical  low level and flow protection and service relay output signal.

Model MX C/A
Constant operation metering pump with analogue 0-100% manual adjustment including frequency reduction mode for low flow rate requirements whilst maintaining accuracy performance across both dosing output ranges, selection of pump output range is through the touchpad with LED indication confirming the pumps flow output between 100% frequency range and 20% frequency range.
MX C/AL model with low level protection and LED alarm (level switch on request).
 
Model P/D
Metering pump with digital display and programming keypad indication LED's for power, water meter, low level protection with Divide and Multiply modes with pulse smart memory software that monitors water meter signal frequency and automatically adjusts the pumps stroke speed to ensure harmonious and stable dosing throughout.
low level protection and LED alarm (level switch on request).
 
Model Multifunction
Microprocessor metering pump with digital display with programming keypad indication LED's for power, input signal and low level protection with Manual, Divide Multiply and PPM proportional modes, proportional 420mA input signal normally from a instrument controller or flow sensor signal, internal 7 day timer to program for the pump to run for a preset time either hourly, daily or weekly to automatically dose into the system.
 
PPM Dosing 
Proportional parts per million dosing using a impulse water meter to is commonly used in many water treatment applications particularly dosing chlorine or sodium hypochlorite to maintain ppm levels in the system, by programming the pulse signal, chemical concentration, cc/injection and the required PPM the pump will automatically dose calculating flow to the required ppm maintaining the desired chemical treatment.
 
Proportional 420mA
Pump is controlled by a  420mA signal to adjust the stroke rate proportional to the incoming mA signal therefore a 4mA signal dosing is stopped pump in standby as the value  increases the pumps strokes frequency until the input signal reaches 20mA with the pump dosing at maximum output. The pumps behaviour can be reversed with 4mA 100% dosing and 20mA dosing in standby with stroke rate programming of minimum and maximum pump output, increasing milliamp signal when pump is stopped and descreasing milliamp signal to have pump dosing at maximum output.
 
Manual Mode
Metering pump can be programmed to operate within its stroke frequency rate with the output controlled in three ways as a simple yet effective way of providing chemical dosing on a continuous cycle throughout the day, the pump pulse frequency can be set pulses per minute, pulses per hour pulses per day.
 
Timed Dosing Mode
By using the metering pumps internal timer dosing can be scheduled either daily or weekly providing independent and effective way of chemical treatment without dependance of any external equipment, the pump can be programmed to dose eight times daily or dose eight times per week.
 
Alarm features
Audible buzzer can be enabled for missed pump pulses
Water meter pulse frequency prgram exceeded
Flow sensor when enabled will monitor dosing output of the pump and activate the service relay output alarm in the event there is no signal being received from the flow sensor indicating chemical isn't' being dosed.
