Dositec Dostec 50 Industrial Variable Speed High Volume Diaphragm Head Fertiliser Dosing Pump with Micrometric Safety Regulator Lock (415-1045LPH)

The Dositec Dostec 50 Diaphragm Dosing Pump is a robust, high-capacity, and highly accurate metering solution designed for demanding industrial and agricultural dosing applications. With a diaphragm dosing range of 415 to 1045 litres per hour, this positive displacement pump is perfect for wastewater treatment plants, industrial process systems, fertigation in large-scale agriculture, and chemical dosing in water treatment.

Built for long-term reliability and safe operation, the Dostec 50 features a fully isolated diaphragm head that separates the dosing fluid from internal components using FPM bellows, effectively preventing leaks and chemical damage. Its PTFE-reinforced diaphragm ensures resilience under harsh operating conditions, handling everything from corrosive acids to high-viscosity chemical solutions.

The variable frequency drive (VFD) offers control flexibility between 10% and 120% of maximum capacity, allowing the user to fine-tune dosing rates to match process needs with pinpoint accuracy. Additionally, a micrometric regulator with locking mechanism ensures consistent dosing without drift, even during continuous use.

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.
