Why Ordinary Pumps Fail
in High-Salinity RO Applications
Standard triplex pumps create pulsation at 100 bar — membrane stress leads to premature failure.
Brass & mild steel corrode rapidly in brakwater and seawater above 8,000 PPM TDS.
High vibration and noise shorten motor bearings and mechanical seal life.
Overseas sourcing means weeks of downtime waiting for replacement parts.
Competing pump brands offer no local technical support or stock in South Africa
The Mixtron Alpha Advantage
- Patented 5-piston rotary system delivers smooth, consistent, pulse-free flow — no membrane stress.
- Technopolymer head and AISI 316 stainless steel components resist the most aggressive saline environments.
- Direct motor flanging eliminates coupling vibration — ultra-quiet, extended service life.
- DOSECO holds local SA stock — fast delivery, no import delays, no production downtime.
- DOSECO provides hands-on technical support across South Africa as your official Mixtron agent
Engineering Built for Extreme Conditions
Every component selected to perform where salt, pressure and heat destroy ordinary pumps.
5-Piston Rotary System
More homogeneous delivery than traditional triplex designs. Low pulsation. Better for RO membranes.
AISI 316 Stainless Steel
Critical wetted components in marine-grade stainless. Built to handle high-salinity feed water without corrosion.
Technopolymer Head & Body
Engineering polymer reduces weight by 40% and eliminates galvanic corrosion — ideal for seawater applications.
Direct Motor Flanging
Pump mounts directly to motor shaft — no coupling, no bell, no vibration transfer. Noise reduced to minimum.
Rated to 65 °C
Brass inserts allow operation in warm-water conditions including solar-assisted and pre-heated RO feed systems.
Easy Installation & Service
Designed for fast on-site maintenance. Reduced downtime. Compatible with standard motor frames across SA.
Seawater RO Feed
Salinity: 32,000 – 45,000+ PPM TDS
Desalination plants, coastal industrial water supply, offshore and marine applications.
- AISI 316 stainless steel wetted parts resist chloride attack
- P.S (Polished Stainless) variants recommended for maximum corrosion resistance
- 100 bar pressure capability handles full seawater osmotic pressure
- Smooth rotary flow protects high-cost RO membranes from fatigue
Brakwater RO Feed
Salinity: 1,000 – 35,000 PPM TDS
Inland borehole treatment, municipal water supply, agricultural and industrial RO systems across SA.
- Handles variable salinity common in inland brakwater sources
- Technopolymer construction resists mineral scale and chemical dosing contact
- N.B (Natural Body) variants suitable for less aggressive brackish applications
- Full range from 1 l/min to 50 l/min covers small to large brakwater plants
