Pump as Turbine: Harnessing Energy Through Reverse Flow

Pump as Turbine (PAT) is an innovative technology that transforms a standard pump into a turbine, allowing it to generate power when operating in reverse. This concept is built on the principle of reverse flow, where a pump, instead of moving fluid through the system, harnesses the energy of the fluid as it flows in the opposite direction. By doing so, PAT systems capture energy that would otherwise be wasted and convert it into useful mechanical or electrical power.

The transformation of a pump into a turbine relies on strategic adjustments to the hydraulic design of the pump. The key is optimising internal components, enabling the pump to efficiently convert the kinetic energy of the flowing fluid into rotational power. This energy can then be used to generate electricity or drive other mechanical equipment, making it a cost-effective and sustainable solution for many applications.

For a PAT system to operate effectively, certain minimum requirements must be met. These include an inlet pressure of at least 2 Bar and a flow rate of 30 m³/h or higher. These conditions make PAT technology particularly suitable for systems with abundant high-pressure, high-flow fluid sources, such as in water supply networks, industrial processes, or energy recovery applications.

The ability to repurpose standard pumps for energy generation not only reduces energy costs but also contributes to improving overall system efficiency. By leveraging the potential of fluid energy that would otherwise be lost, PAT systems help minimise energy consumption and environmental impact. This makes them a valuable technology for industries seeking more sustainable and economically viable solutions for fluid handling and energy recovery.

In conclusion, Pump as Turbine systems represent a breakthrough in energy efficiency, offering a simple yet effective way to generate power from fluid flow. Ideal for a variety of industrial and commercial applications, PAT technology stands out as an innovative, cost-saving solution that contributes to both sustainability and reduced operational costs.
