DOSECO SM-SERIES PUMPS

SM-Series: Digital Precision
Stepper-Motor Dosing Pumps

Four models. Two power configurations. One commitment: accurate chemical

metering from 1% to 100% of design flow, every hour of every day.

High-Performance Chemical Metering for South African Conditions

The DOSECO SM-Series stepper-motor dosing pump is engineered for the realities of South African water treatment — variable voltage supply, aggressive chemicals, remote off-grid installations, and zero tolerance for inaccurate dosing.
Each model is a diaphragm-type positive-displacement pump with stepper-motor actuation — providing smooth, pulsation-free chemical delivery that maintains stated accuracy across the full operating range.

The current SM-Series range provides manual on/off operation with two actuation options: level-control switching (for tank-based or float-switch operation) and timer-based control for timed dosing cycles.

Coming Mid-July 2026: Smart SM-Series with proportional 4–20mA control, water-meter pulse dosing, and pH/Redox probe integration. Register your interest now.

★ SM-06/5 is the most commonly specified model for South African municipal and industrial water treatment applications. All models available in SM-AX (AC mains) and SM-DX (24V DC solar-ready) power configurations.

POWER CONFIGURATIONS

SM-AX (AC Power) & SM-DX (24V Solar-Ready DC)

SM-AX Series

AC Power — Wide Voltage Range

The SM-AX is the standard industrial specification DOSECO dosing pump, designed for connection to South African AC mains supply. The wide-range voltage input (90–260V AC) handles the supply voltage fluctuations common in South African municipal and industrial environments without impacting dosing accuracy.

What’s Included — The Full Professional Installation Kit

  ✅ SM-AX stepper-motor dosing pump unit

  ✅ Foot valve and suction strainer

  ✅ Injection fitting/check valve assembly

  ✅ Suction and discharge tubing (chemical-rated)

  ✅ Wall-mounting bracket

Optional: float switch, timer module, chemical tank

SM-DX Series

24V DC — Off-Grid & Solar Power

The SM-DX is purpose-engineered for South Africa’s growing off-grid water treatment sector — solar-powered borehole systems, remote rural water supply, agricultural irrigation dosing and any application where reliable AC mains supply is unavailable or impractical.

 

At 24V DC, the SM-DX connects directly to a standard solar charge controller output or battery bank — no inverter required. This simplifies installation, reduces system cost, and improves reliability in remote locations.

SM-DX Off-Grid Applications

   ☀️ Solar-powered borehole chlorination (Limpopo, Mpumalanga, Northern Cape)

   ☀️ Remote agricultural fertigation and pH dosing

   ☀️ Rural community water treatment kiosks

   ☀️ Game lodge and eco-estate water systems
