A Beginner-Friendly Guide to Centrifugal, Diaphragm, and Gear Pumps
Whether you’re new to pump systems or brushing up on the basics, it’s important to know how pumps operate. Understanding different types of industrial pumps—and how to best use them—can save time, money, and significant hassle. At DXP Quadna, we’ve helped customers across a variety of industries find the right pump for their application. Here’s a simple breakdown of three of the most common pump types: centrifugal, diaphragm, and gear.
Centrifugal Pumps: The Standard Choice for Flowing Liquids
Centrifugal pumps are the most widely used type of industrial pump because they’re efficient, easy to maintain, and ideal for moving large volumes of low-viscosity fluids like water, chemicals, or light oils. These pumps use a rotating impeller to create velocity that turns into flow. Because they thrive in high-flow, low-pressure environments, you’ll find them in everything from municipal water systems to mining operations.
When properly matched to the job, centrifugal pumps offer excellent energy efficiency and long-term reliability. At DXP Quadna, we often engineer centrifugal systems that are part of a larger packaged solution—custom-built to meet your performance and installation needs.
Diaphragm Pumps: Tough and Tolerant
Need to move a fluid that’s abrasive, corrosive, or contains solids? That’s where diaphragm pumps shine. These positive displacement (PD) pumps use a flexible diaphragm that pulses back and forth to draw in and push out fluid. No rotating seals means minimal leakage and low risk of contamination, making them ideal for handling chemicals, slurries, or wastewater.
Diaphragm pumps are also self-priming and can run dry without damage, which adds to their versatility. Whether you’re dealing with food-grade materials or hazardous waste, these pumps are often the safest choice.
Gear Pumps: Precise and Powerful
When consistency matters, gear pumps deliver. These pumps move fluid using gear meshing inside a tight chamber. Because of their precise flow control and ability to handle high-pressure applications, they’re often used in lubrication systems, fuel transfer, and hydraulic applications.
Gear pumps are positive displacement so they maintain a constant flow regardless of pressure changes. This makes them especially useful for metering applications or moving viscous liquids like oils and resins.
