Single Screw Pumps

Single Screw Pumps: Working Principle, Advantages, Application and Maintenance

Single screw pumps are positive displacement pumps used to move liquids, slurries and difficult fluids at a controlled rate. They are useful where the fluid may have high viscosity, solids, fibres or air.  Understanding the single screw pump working principle makes pump selection easier. It also helps maintenance teams understand which parts need regular attention. A progressive cavity pump is another common name for this […]

Rotary Gear Pump: Working Principle, Types, Applications & Benefits

A rotary gear pump is a positive displacement pump used to move liquids at a steady rate. It is often selected for oils, chemicals, fuels, and other fluids that need controlled transfer.  Understanding the rotary gear pump working principle helps industries choose the right pump for their process. The pump type, fluid viscosity, pressure, temperature and flow rate all affect selection.  A rotary […]

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.
