Dositec Dostec 50 AC High-Volume Advanced Control Piston Dosing Pump with Remote Monitoring

The Dostec 50 AC Piston Dosing Pump is built for high-volume, high-precision dosing applications in water treatment, agriculture, chemical processing, and other demanding industrial sectors. With a flow capacity ranging from 600 to 1200 litres per hour, this advanced metering pump is designed for automated regulation, remote access, and precise chemical delivery even under challenging conditions.

At its core, the Dostec 50 AC features a robust piston mechanism, engineered for reliable performance in high-pressure environments. This model includes full analog control, proportional dosing, and seamless integration with SCADA systems via ModBus. Operators can manage dosing programs manually, automatically, or remotely—ensuring flexibility and control across a wide range of dosing requirements.

Tailored for professional users, the Dostec 50 AC offers a suite of intelligent dosing functions, including low pulsation, slow suction for viscous chemicals, and calibration/test modes. A full array of safety sensors safeguards operations, offering real-time alerts for flow, pressure, level, temperature, and diaphragm integrity.
