Micropump AC
The Micropump AC magnetic gear micropumps are positive displacement pumps designed for applications where reliability, precision, and compactness are essential.
Equipped with an AC motor and featuring a “suction shoe” design, these pumps ensure accurate, continuous microdosing, long operational life, and complete leak-free performance.
Techma GPM is the official Micropump distributor for Italy and Europe.
We provide technical support, custom configurations, and OEM integration consulting to meet specific application requirements.
Serie GA
The GA magnetic drive gear pumps series provide a precise flow without pulsations, ideal for continuous and discrete dosages and micro dosages. Thanks to the “suction shoe” designed by Micropump, the GA series pumps automatically compensate the wear, this feature reduces leakage and ensuring a longer pump life. The GA pumps are available in a wide range of materials and configurations such as SS316 for the body, PPS or PEEK for the gears and PTFE, EPDM or Viton for the static sealing O-ring.

Get in touchFrequently Asked Questions
What’s the difference between Micropump AC and DC?
AC pumps are ideal for continuous operation in fixed installations, while DC models suit portable or energy-efficient systems.
Are AC pumps suitable for the food industry?
Yes, many versions comply with hygiene requirements and can dose flavorings, colorants, and additives.
Can the dosing rate be adjusted?
Yes, by controlling frequency or adjusting inlet pressure and downstream valves.
What type of positive displacement pumps are Micropump AC models?
Micropump AC units are magnetic gear positive displacement pumps, designed for precise microdosing of liquids through magnetic coupling with no direct contact between motor and fluid.
