High-accuracy chemical dosing systems for water treatment, industrial processes, and off-grid applications across South Africa.
South Africa’s stepper motor dosing pump specialists providing advanced dosing pumps for precision chemical metering. Doseco dosing pumps deliver accurate, pulsation-free flow control across demanding industrial applications.
Chemical Dosing Pump Professionals know what it feels like when you need to turn down your dose and the on-site metering pump loses prime, or, worse yet, it will not function accurately below a 15% turndown.
You shouldn’t have to struggle like that, especially on a Friday afternoon when there are better things to do.
We know how that feels.
DOSECO stepper-motor dosing pumps deliver accurate chemical metering down to 1% of full design flow. Conventional Solenoid technology simply gives up.
Changing to an industry-leading Doseco Stepper-Motor pump means your treatment is accurate, reliable, and efficient.
The Best Change You Will Make This Year.
You won’t struggle with priming, overdosing, or chemical waste, and your afternoons will be yours.

ACCURACY
Our dosing pumps are engineered for industries requiring consistent accuracy and reliable chemical dosing. Doseco stepper motor technology ensures stable flow, reduced pulsation, and long service life in demanding environments.
The Problem Every Water Treatment Professional Knows
Having served the water treatment specialist industry for many years, we understand that when a dosing pump loses accuracy as it is turned down below 15% of its design flow, the only choice is to buy a smaller unit.
With DOSECO SM Pumps, that is not your reality anymore.
A Doseco Stepper Motor Dosing Pump will operate effectively from 1% to 100% of it’s design flowrate, guaranteed.
Off-peak low-demand conditions push solenoid pumps into their “dead zone” — a period of zero reliable dosing that creates compliance risk and unprotected water supply.
To compensate for low-flow inaccuracy, operators overdose — wasting expensive treatment chemicals and risking regulatory non-compliance from excess chlorine or incorrect pH values
Solenoid-driven diaphragm pumps can create pressure peaks up to 2.5 X the counter-pressure on each stroke — stressing pipe fittings, injection points and downstream equipment.
Conventional Solenoid activated diaphragm dosing technology loses metering accuracy rapidly below 15% of design flow — creating unpredictable chemical delivery exactly when precision matters most.



Stepper Motor Technology
A DOSECO stepper-motor diaphragm pump doesn’t guess at low flows.
It measures every single step.
Here’s why that matters to your process.
Accurate chemical dosing from 1% to 100% of flow rate.
15× better low-flow performance than conventional solenoid pumps.
Smooth, pulse-free dosing with no pressure spikes.
Less wear on pipes, valves, and injection points.h South African environments
Dose only what your system needs.
Reduce chemical waste and improve compliance.
