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 vs external gear pump

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 […]

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 […]

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 […]

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.
