External Gear Pumps

External Gear Pump: Advantages and Industrial Applications

An external gear pump is a positive displacement pump designed to move fluids by using two meshing gears. It is valued for its simple construction, steady fluid transfer, and ability to work across many industrial duties.  The right pump depends on the fluid, pressure, viscosity, temperature, and required flow rate. Understanding these factors helps engineers choose a […]

Internal Gear Pump vs External Gear Pump: Which Should You Choose?

Choosing the right positive displacement pump depends on the fluid, pressure, viscosity, temperature, and duty cycle. Two common options are internal and external gear pumps. Both use rotating gears to move fluid, but their construction and operating methods are different.  Understanding these differences helps engineers select a pump that matches the process. An internal gear pump can be […]

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.
