PRIMARY APPLICATION · HIGH PRESSURE PUMPS
Mixtron Alpha Series — South Africa’s Most Advanced Reverse Osmosis Feed Pump
In a reverse osmosis system, the high-pressure feed pump is the component that determines everything — membrane efficiency, water quality, energy consumption and total system lifespan. The Mixtron Alpha Series is engineered from the ground up for RO feed duty, and it outperforms conventional triplex pump technology in every measurable category.
Why Pulse-Free Delivery is Critical for RO Membrane Integrity
Conventional triplex (three-piston reciprocating) high-pressure pumps generate pressure pulses with every piston stroke. These pressure spikes cause cyclic fatigue stress on RO membrane fibers, accelerating delamination and reducing rejection performance over time.
The Mixtron Alpha Series uses a patented rotary piston architecture that produces a genuinely homogeneous, pulse-free pressure output. Stable differential pressure across the membrane means no cyclic stress — measurably extended membrane service life, lower operational expenditure and more consistent permeate quality.
Technopolymer Construction — Full Chemical Compatibility
Mixtron Alpha Series pumps are constructed from high-performance engineering technopolymers on all fluid-contact surfaces. Full compatibility with brackish water, seawater feeds, antiscalant solutions and pH-adjustment chemicals — no corrosion risk regardless of salinity or chemical concentration.
Consistent Differential Pressure = Better Rejection Rates
RO membrane rejection efficiency is directly linked to the stability of the differential pressure across the membrane. The Mixtron Alpha’s pulse-free steady-state output maintains optimal pressure differential continuously — consistent, predictable rejection rates throughout the entire operating cycle.

Secondary Application · High Pressure Pumps
Mixtron Alpha Series for High-Pressure Misting Systems in South Africa
Effective misting is a pressure problem. The Mixtron Alpha Series operates in the 50–100 bar range — precisely where calibrated fog nozzles produce sub-10 micron droplets that evaporate instantly upon contact with air, achieving evaporative temperature reductions of up to 10°C without wetting people or surfaces.
The Physics: Why 50–100 Bar and Pulse-Free Matters
At pressures below 50 bar, fog nozzles produce droplets above 20–30 microns — large enough to fall and wet surfaces. At 70–100 bar, the Alpha Series drives droplets below 10 microns, achieving near-instant evaporation and maximum cooling efficiency. Critically, pressure fluctuations from pulsating pumps create droplet size variation across the nozzle circuit. The Mixtron Alpha’s pulse-free output ensures every nozzle operates at identical, steady pressure — uniform fog distribution across the entire system.
South African Misting Applications
- ✓Outdoor restaurant, bar and entertainment venue cooling
- ✓Sports stadium, event arena and outdoor event cooling
- ✓Industrial warehouse and factory floor humidity control
- ✓Construction site and quarry dust suppression
- ✓Composting facility and waste transfer station odour control
- ✓Mushroom cultivation and cold-room humidity management
- ✓Greenhouse microclimate humidification
- ✓Data centre supplementary cooling systems
Misting Pressure Range
| 60 bar systems | Standard commercial misting |
| 80 bar systems | High-efficiency cooling |
| 100 bar systems | Ultra-fine fog, max evaporation |
| Flow range | 1 – 60 l/min |
Up to 10°C Cooling Reduction
Sub-10 micron droplets evaporate instantly on contact with air, absorbing latent heat and reducing perceived ambient temperature by up to 10°C — without wetting surfaces or occupants.
Uniform Fog at Every Nozzle
Pulse-free output ensures every nozzle in the circuit operates at identical steady pressure. No dry zones, no dripping nozzles — consistent, uniform fog distribution system-wide.
Quiet Enough for Public Spaces
Near-zero vibration and low acoustic output make the Alpha Series suitable for hospitality, entertainment and commercial venues where pump noise in a public environment is a design constraint.
Design Advantage. Price Advantage. Both. Why Mixtron Wins for South African RO.
The South African RO market has long been served by established European and American pump brands — reliable, respected, but premium-priced and dependent on lengthy import cycles for spares. Mixtron changes the equation: genuine engineering superiority, Italian manufacturing quality, and a total cost of ownership that makes every RO project more commercially viable.
Rotary Piston vs Triplex: A Fundamental Advantage
Where conventional triplex pumps produce three pressure pulses per revolution, the Mixtron rotary piston design produces continuous, smooth flow — a genuine engineering leap that protects membranes and eliminates the need for pulsation dampeners in the system design.
Direct Motor Flanging — Fewer Components, More Reliability
The Alpha Series flanges directly onto the motor shaft — eliminating the mechanical coupling, housing and all associated alignment issues and wear points. Fewer failure modes, easier installation and lower long-term maintenance cost.
Technopolymer — Corrosion Cannot Happen
Fluid-contact surfaces constructed from high-performance engineering polymers provide absolute corrosion immunity to saline feeds, antiscalant chemicals, pH acids and biocides. The pump cannot corrode from the inside.
Total Cost of Ownership — The Compelling Case
Lower acquisition cost, extended membrane life, reduced maintenance intervals and locally available spares deliver a TCO advantage that compounds over the system's operational life.
Near-Zero Vibration — System Protection Built In
Low vibration output protects every connected component — pipes, fittings, pressure vessels and instrumentation. Directly reduces vibration-induced failure, a persistent challenge in South African RO installations.
