Product Overview
The Dositec AC2-10D is an advanced control diaphragm chemical dosing pump designed for accurate and automated liquid chemical injection in fertigation, water treatment, agriculture and industrial dosing systems.
With an injection range of 6.5–9.5 L/h and pressure capability up to 1500 kPa / 15 bar, the DTEC-AC2-10D is ideal for low-flow applications where chemical compatibility, accuracy and reliable dosing control are important. The diaphragm dosing head provides separation between the chemical and drive mechanism, making it a suitable option for many chemical dosing applications where a diaphragm style pump is preferred over piston dosing.
The Dostec AC Advanced Control range supports multiple control options, including manual flow control, proportional pulse control, analogue 0/4–20 mA control, batch dosing and ModBus supervisory control. This allows the pump to be integrated into automated fertigation systems, water treatment plants, flow meter-controlled dosing systems and industrial chemical injection setups.
Advanced dosing functions such as low pulsation discharge, slow suction and low flow operation help improve dosing performance across different chemical types and operating conditions. The Dostec AC range can also support additional safety inputs such as level sensor, pressure sensor, flow failure detector, temperature sensor and diaphragm leakage detection.
The DTEC-AC2-10D is a strong choice where accurate, automated low-flow diaphragm dosing is required at higher operating pressures.

Frequently Asked Questions
What is the DOSTEC® AC Diaphragm used for?
The DOSTEC® AC Diaphragm is an advanced automatic dosing pump designed for accurate chemical dosing in water treatment, chemical processing, food, agriculture and industrial applications.
What flow and pressure range is available?
The DOSTEC® AC range covers flow rates from 3 to 1200 L/h, with pressure up to 20 bar, depending on the selected model and dosing head. Diaphragm models are available in a wide range, including smaller high-pressure versions through to high-flow models over 1000 L/h.
What operating modes does the DOSTEC® AC have?
The DOSTEC® AC includes multiple operating modes: manual, analogue 0/4–20mA, proportional to flow rate, proportional by pulses, batch dosing by volume, batch dosing by time and ModBus RTU control.
What is the difference between the diaphragm and piston version?
The diaphragm version uses a PTFE diaphragm with a fibre-reinforced elastomer base, making it suitable for many chemical dosing applications where separation between the drive mechanism and chemical is preferred. The DOSTEC® AC range is available in both diaphragm and piston configurations depending on the chemical, pressure and flow requirement.
What pump head materials are available?
The DOSTEC® AC can be supplied with pump head materials including PP, PVDF and stainless steel 316L. Correct material selection is important and should be matched to the chemical being dosed.
Can the DOSTEC® AC Diaphragm work with a water meter?
Yes. The DOSTEC® AC can dose proportionally from a pulse signal supplied by a water meter or flowmeter. It supports X:Y pulse mode for low-frequency pulses and %/ppm flowmeter mode for high-frequency flowmeters.
Can the DOSTEC® AC be controlled by a 4–20mA signal?
Yes. The pump can dose proportionally to a 0/4–20mA analogue signal, making it suitable for use with controllers, sensors, PLC systems and other automated dosing setups.
Does the DOSTEC® AC support ModBus?
Yes. The DOSTEC® AC supports RS-485 ModBus RTU control. The manual lists RS485 half-duplex communication using A, B and GND, with 9600 baud rate, 8 data bits, no parity and 1 stop bit.
What alarms and monitoring features are included?
The DOSTEC® AC includes monitoring and alarm options such as level alarms, flow fault alarm, diaphragm leakage alarm and overpressure alarm. It also supports real-time monitoring, counters, 4–20mA output, pulse output and alarm relay outputs.
How should the DOSTEC® AC Diaphragm be installed?
The pump should be mounted vertically on a rigid surface, protected from water, away from heat sources and with adequate ventilation. A 150 micron suction filter is recommended, and a pressure relief valve should be installed close to the pump to protect the pump and pipework from overpressure.
