DOSECO DOSING PUMP SOUTH AFRICA- RELIABILITY · LOW PULSATION · APPLICATION RANGE
The water treatment professional deserves a dosing pump that doesn't demand attention. One that doses correctly — smoothly, without pressure spikes — whether it's treating drinking water, industrial process water, or a remote off-grid borehole system.
Every solenoid dosing pump stroke is, mechanically speaking, a small collision. The solenoid energises, the electromagnet
snaps the plunger forward, the diaphragm makes its full stroke at maximum speed — and the resulting pressure spike
can reach 2.5 times the system counter-pressure before the check valve opens, and the chemical is delivered.
The reverse action now occurs, where the solenoid-driven diaphragm snaps back, this is where problems often occur.
The rapid suction stroke with a fluid like Sodium Hypochlorite can create a partially full fluid chamber, which builds over time.
The resultant loss of prime literally stops the solenoid pump from metering any fluid at all, and the system stops.
For 24/7 applications — and most water treatment systems operate continuously — solenoid dosing pumps are often
treated as a consumable item rather than a durable asset. Industry practitioners note that solenoid pumps are
frequently replaced rather than repaired, and that reliability in round-the-clock service is a known limitation.
The water treatment professional running a remote borehole installation, a 24-hour industrial process, or a municipal
supply system doesn’t have the luxury of a nearby spare pump. Reliability isn’t a preference — it’s a requirement.
A dosing pump failure at 2 am in a remote installation isn’t a maintenance inconvenience — it’s a water quality crisis. Hours of untreated supply. Emergency call-out costs. Compliance exposure.
We understand that for the water treatment professional managing multiple sites, or a remote system with limited access, pump reliability is the metric that matters most. The most accurate pump in the world is worthless if it fails in the field.
That’s why DOSECO’s stepper-motor drive design prioritises mechanical longevity alongside dosing precision.
The smooth, controlled stroke eliminates the violent mechanical shock of solenoid actuation — extending the service life of every wetted component and every downstream fitting.
The DOSECO SM-Series stepper motor drives the diaphragm directly via the integrated not a solenoid snap. Every stroke is a smooth, speed-managed movement through the full diaphragm travel. Pressure builds progressively to meet counter-pressure. The suction phase can be slowed independently to prevent cavitation and ensure full chemical uptake.
The result is a pump that is quiet, smooth, and free of the vibration and hydraulic shock that characterises solenoid technology. For the installation — and for the components around it — this translates directly into longer service life and fewer unplanned failures.

With a DOSECO SM-Series stepper-motor pump at the heart of your dosing system, you'll notice the difference from the first week of operation. The installation is quieter. The injection fittings stay tight. The dosing log shows consistent chemical delivery — not the ragged on-off pattern of a solenoid pump trying to manage a flow rate it wasn't designed to handle.
Over months and years, the change compounds. Fewer emergency call-outs. Lower replacement parts cost. A dosing system that earns your trust because it has earned its reliability through engineering — not just through luck.
With DOSECO, you WON'T accept a dosing pump that vibrates, hammers your pipework, and fails in 24/7 service. You WON'T design your installation around the weaknesses of solenoid shock-actuation. You WON'T face an emergency call-out to a remote borehole site because your dosing pump couldn't handle continuous operation. The water treatment professional you are deserves equipment that matches your professionalism.
