Product information

Dostec 50 are designed for use in industries such as agriculture, wastewater handling and treatment, process water treatment, and various industrial processes.

  • 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.
