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 Pumps

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 […]

Three Screw Pump Working explained

How a Three Screw Pump Works ?

A three screw pump is a positive displacement rotary pump built around a simple but highly reliable principle: one power rotor and two idler rotors, running together inside a precision-bored housing. Also called a triple screw pump, it has been a workhorse in power generation, marine, and petroleum industries for over five decades. Delta PD […]

Internal Gear Pump

How Internal Gear Pumps Improve High-Viscosity Fluid Handling

Handling thick fluids is never simple in industrial systems. Materials like oils, resins, bitumen, polymers, and adhesives do not flow easily. They resist movement and demand steady pressure to transfer smoothly. In such cases, pump selection becomes critical for stable operations.  Many industries depend on reliable pumping systems that can manage flow without breakdowns or pressure loss. […]

Rotary Trochoidal Gear Pumps

What Are the Benefits of Using Rotary Trochoidal Gear Pumps

A rotary trochoidal gear pump works on a simple but effective mechanical principle. It moves liquid by trapping it between rotating gears and pushing it out. The movement is steady and controlled, which helps many industrial systems that need a consistent flow. A rotary gear pump is a type of positive displacement pump. It works without relying […]

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.
