What is a hydraulic diaphragm dosing pump used for?

Introduction

Hydraulic diaphragm dosing pumps are precision metering devices designed to deliver accurate volumes of fluid and chemicals into various industrial processes. Because of their design, these pumps can handle a wide range of chemicals, including corrosive, viscous, and high-temperature fluids. They are utilized in processes demanding accuracy and reliability due to the ability to maintain precise flow rates and handle challenging fluid properties.

Working Principle of Hydraulic Diaphragm Dosing Pumps

The working principle of a hydraulic diaphragm dosing pump is based on the reciprocating motion of a diaphragm inside a housing. The diaphragm is driven by hydraulic fluid pressure generated by a pump shaft. This creates a vacuum on the suction side, allowing fluid to enter the chamber, while the pressure side discharges the fluid when the diaphragm moves inward. The absence of moving seals makes it suitable for handling hazardous or toxic chemicals.

Applications of Hydraulic Diaphragm Dosing Pumps

Hydraulic diaphragm dosing pumps are employed in various industries, including:

• Water and Wastewater Treatment: Used for precise chemical dosing in treatment processes.
• Pharmaceuticals: Ensures accurate dispensing of ingredients and solvents.
• Chemical Processing: Suitable for corrosive and reactive chemicals.
• Petrochemicals: Used in operations involving oil and gas processing.
• Food and Beverage: Facilitates precise ingredient dosing ensuring product quality.
