What is a high pressure process diaphragm pump?

Introduction

High pressure process diaphragm pumps are specialized pumps renowned for their ability to handle aggressive and high-viscosity fluids under extreme pressure conditions. These pumps utilize a reciprocating diaphragm to move fluid, thereby ensuring that the fluid does not come into contact with moving parts, which is essential in maintaining the integrity of the pump when dealing with corrosive or hazardous liquids.

Working Principle of High Pressure Process Diaphragm Pumps

These pumps operate based on a simple reciprocating motion. A diaphragm is flexed back and forth by a mechanical drive system. As the diaphragm moves back, it creates a vacuum, drawing fluid into the pump chamber through an inlet check valve. As the diaphragm moves forward, it compresses and expels the fluid through an outlet check valve. The cycle repeats to maintain a continuous flow.

Typically, these pumps can handle pressures exceeding 1000 psi (pounds per square inch) and can manage flow rates of up to 100 gallons per minute (GPM), depending on the model and manufacturer specifications.

Key Features and Advantages

• Leak-Free Operation: The sealed diaphragm design ensures that no fluid leaks occur, which is crucial for hazardous substances.
• Corrosion Resistance: Materials such as PTFE (polytetrafluoroethylene) and stainless steel are commonly used for diaphragms and housing to resist chemical attack.
• Variable Flow Control: Flow rates can be precisely adjusted by varying the stroke length or speed, allowing for flexible control.
• Low Maintenance: Fewer moving parts result in less wear and tear, reducing maintenance requirements.

Applications

High pressure process diaphragm pumps are used across a range of industrial applications due to their reliability and robustness. Some typical applications include:

• Chemical processing industries for handling corrosive and volatile chemicals.
• Oil and gas sectors for transferring high-viscosity liquids and slurries.
• Pharmaceutical industries where contamination-free processing is critical.
• Water treatment facilities, especially in dosing and mixing corrosive agents.
