Dostec 50 Industrial Variable Speed High Volume Piston Head Fertiliser Dosing Pump with Micrometric Safety Regulator Lock (330-1000LPH)

The Dositec Dostec 50 Industrial Piston Dosing Pump is a heavy-duty, high-capacity dosing solution engineered for industrial, agricultural, and water treatment applications. With variable speed control and a micrometric flow regulator with a built-in safety lock, this pump provides exceptional precision and adaptability for processes requiring accurate, continuous liquid injection.

Designed to handle flow rates from 330 to 1000 litres per hour, the Dostec 50 combines positive displacement piston technology with corrosion-resistant construction, making it ideal for dosing aggressive chemicals, concentrated acids, and fertilisers across industrial plants, wastewater facilities, and large-scale fertigation systems.

The FPM-sealed separation between the pump body and the dosing head ensures leak-free operation and protects internal components from chemical exposure, reducing maintenance and extending operational life. A variable frequency drive (VFD) enables users to modulate pump output from 10% to 120%, aligning dosing rates with changing system demands.

FEATURES

• Configuration: With diaphragm and piston variants and heads available in PP, PVDF and INOX.
• Flow rates: from 160 to 1200 l/h for piston models and 100 to 1080 l/h for diaphragm models.
• Safety: The separation between the liquid end and the pump body by means of an FPM diaphragm ensures safe operation without risk of leakage, protecting the vital elements and extending their life.
• Strength: DOSTEC 50 metering pumps are constructed with materials that can handle most liquids, including highly concentrated acids.
• Adjustment: Equipped with a micrometer control with safety lock function, this pump facilitates fine and stable adjustment, preventing unexpected changes during use.
• Durability and performance: Featuring heavy-duty PTFE diaphragms, these pumps are designed to last, withstand harsh environments, and maintain efficient performance.
• Control: The ability to adjust flow through a variable frequency drive (from 10% to 120% of maximum flow) gives users the ability to tailor pump operation to the specific needs of each job, improving resource management and operational efficiency.
