How Does an External Gear Pump Work? Types, Uses & Buying Guide

An external gear pump is one of the most reliable and widely used positive displacement pumps in industrial fluid handling. It moves fluid using two externally meshing gears housed inside a close-tolerance casing. As the gears rotate, they trap fluid between the gear teeth and the housing, pushing it from the inlet to the outlet. […]

Message from Chairman Mr. Madhukumar H. Shah.

Since our inception in 1968, Delta has been committed to manufacturing high-quality Positive Displacement Pumps with a focus on reliability, engineering precision, and long service life. Our early collaborations with leading European manufacturers and our pioneering introduction of screw pumps in India laid the foundation for our technical strength.

Over the decades, we have continuously evolved by understanding the challenges faced by industries — from handling low-viscosity fluids to meeting higher pressure and reliability demands. With advanced metallurgy, precision screw profiles, and a dedicated team of experts, we strive to deliver not just pumps, but complete pumping solutions.

Pumps operating reliably for over 65 years stand as a testament to Delta’s commitment to engineering excellence and long-term performance.
