Introduction

A reciprocating dosing pump is a positive displacement pump that moves fluids at precise flow rates for dosing or dispensing applications. This type of pump is crucial in industries such as pharmaceuticals, water treatment, and chemical processing.

Working Principle of Reciprocating Dosing Pumps

Reciprocating dosing pumps operate using a piston or diaphragm mechanism that moves back and forth within a cylinder. This movement creates a vacuum, drawing fluid into a chamber, and then a forward stroke pressurizes the fluid, pushing it out in a controlled flow. The reciprocating motion is typically driven by a motor or an air actuator.

Types of Reciprocating Dosing Pumps

• Piston Dosing Pumps: Utilize a piston within a cylinder. Ideal for high-pressure applications, up to 1000 bar.
• Diaphragm Dosing Pumps: Use a diaphragm instead of a piston, suitable for handling corrosive or abrasive fluids. Standard pressure range is 1 to 400 bar.

Critical Parameters for Selection

When selecting a reciprocating dosing pump, several key parameters need consideration:

• Flow Rate: Typically ranges from 0.1 ml/h to 5000 l/h, depending on the application.
• Pressure Requirements: Must match the system's needs, usually between 0 and 1000 bar.
• Material Compatibility: The pump materials should be compatible with the fluids being processed, considering factors like corrosion and temperature.
