Introduction

Diaphragm dosing pumps are widely used in various industries for precise fluid handling. This article provides a detailed overview of how diaphragm dosing pumps function, their key components, applications, and a focus on solutions provided by the Depamu company.

Principle of Operation

A diaphragm dosing pump utilizes a flexible diaphragm driven by a motor or solenoid to create a variable volume within a pumping chamber. The diaphragm's movement, in conjunction with check valves, ensures controlled and consistent fluid dosing. The process can achieve flow rates ranging from 0.1 to 1000 liters per hour, depending on the design and application requirements.

Components of a Diaphragm Dosing Pump

  • Drive Mechanism: Typically consists of an electric motor or hydraulic system to drive the diaphragm.
  • Diaphragm: Made from materials like PTFE or elastomer to withstand corrosive substances.
  • Pumping Chamber: Houses the diaphragm and controls fluid movement.
  • Check Valves: Prevent backflow ensuring unidirectional flow.
  • Control System: Allows adjustment of flow rate and pressure delivery.

Advantages and Applications

Diaphragm dosing pumps offer advantages such as high accuracy (±1% of setpoint) and resilience against corrosive chemicals. They are prevalent in industries like water treatment, pharmaceuticals, agriculture, and food processing due to their ability to handle diverse fluids from viscous solutions to volatile chemicals.

Depamu Company Solutions

Depamu is a leading provider of diaphragm dosing pump solutions, offering products characterized by exceptional durability and precision. Their models, such as the DMX series, support flow rates up to 500 liters per hour and pressure ratings up to 400 bar, designed for seamless integration in complex systems.

Numerical Analysis

Numerical analysis of a diaphragm dosing pump involves evaluating parameters such as:

  • Flow Rate: Adjustable from 0.1 to 1000 L/h.
  • Pressure Range: Capabilities reaching up to 400 bar.
  • Accuracy: Precision of ±1% of the set flow rate.
  • Material Compatibility: Diaphragms available in PTFE and elastomer, resistant to a wide pH range of 1-14.
