Introduction

Hydraulic diaphragm metering pumps are crucial in precisely delivering fluids in various industrial processes. Their unique design enables them to handle high-pressure applications and corrosive fluids effectively. This article delves into the applications, working principle, and technical specifications of hydraulic diaphragm metering pumps, with a special spotlight on solutions provided by Depamu Company.

Applications of Hydraulic Diaphragm Metering Pumps

Hydraulic diaphragm metering pumps are predominantly used in environments requiring precise fluid delivery. Key industries utilizing these pumps include:

• Chemical Processing: Accurately injects chemicals at specified rates and pressures.
• Water Treatment: Essential for dosing acids and alkaline solutions, ensuring safe water quality management.
• Oil & Gas: Utilizes pumps for chemical injection in drilling, ensuring antifreeze and corrosion inhibition.
• Food and Beverage: Facilitates the mixing and coating processes through precise additive delivery.

Working Principle

The technology behind hydraulic diaphragm metering pumps involves a reciprocating diaphragm powered by hydraulic fluid. The diaphragm movement varies the volume in a chamber, facilitating fluid flow. The pump operates in four stages:

1. Intake Stroke: Reduces pressure, allowing fluid intake through an opened inlet valve.
2. Discharge Stroke: The diaphragm pressurizes the hydraulic fluid, closing the inlet valve while opening the outlet valve to release the fluid.
3. Refill Stage: Hydraulic fluid refill returns the diaphragm to its original position.
4. Repeat Cycle: Maintains continuous and accurate fluid delivery.

Technical Specifications

When selecting a hydraulic diaphragm metering pump, critical technical parameters include:

• Flow Rate: Typically ranges from 0.1 ml/min to 1000 l/h, allowing flexibility for various applications.
• Maximum Pressure: Can withstand pressures up to 700 bar, catering to high-pressure requirements.
• Accuracy: Offers precision with a deviation of as low as ±1% for assured process consistency.
• Material Compatibility: Constructed using PTFE, SS316, and Hastelloy, ensuring resilience against corrosive substances.
