Wide range of applications and cost savings

The Franklin Electric team recently supported an agricultural business to organise its irrigation system cost-effectively and precisely to its needs. Several well pumping systems were installed in wells 20-30 metres deep.

The project had several requirements for the desired well system:

• The system had to be suitable for various applications, as the fields are irrigated partly with sprinkler cannons and partly with drip hoses. The methods and areas vary constantly and are heavily dependent on the weather and season. The system therefore had to be designed for a wide range of applications in terms of operating points.
• A further focus was on cost savings for the economic optimisation of the operation. Enormous cost savings can be achieved by using the High Efficiency System.
• The customer also wanted a flexible system with multi-range motors that are suitable for all well systems. This allows him to flexibly swap the motor and pump between the wells as required.

Several well pump systems were installed, consisting of permanent magnet motors in the power range of 13-22 kW, VS submersible pumps (VS65/10) made of 304SS, corresponding cabling and a temperature sensor.

The system was supplemented by the perfectly matched DrivE-Tech COMPACT frequency converter with du/dt filter for motor protection. This is quick and easy to install via a mobile app and even enables remote control, real-time monitoring of system performance and remote troubleshooting by Franklin Electric's support team.

 

High-efficiency borehole systems engineered for excellence and sustainability

In all industries and markets, energy consumption is becoming a decisive criterion when selecting new systems and modernising existing ones. It is also becoming one of the most important aspects when pumping water from boreholes or tanks, in addition to the optimum dimensioning, reliability and quality of the system. As the energy consumption of a pump system accounts for up to 90 % of the total life cycle costs, the overall operating costs can be significantly reduced.

With its innovative High Efficiency System (HES), Franklin Electric is setting new standards in the industry. The system enables energy savings of up to 21 %. As a technology pioneer, Franklin Electric has been supplying the submersible pump market with highly efficient permanent magnet synchronous motors since 2017. The high-efficiency borehole pump systems (HES) achieve outstanding levels of efficiency, particularly as a complete package including all components. Several thousand installed units have so far proven this outstanding practicality and show up to double-digit energy savings as well as significantly improved efficiencies.

The key factor in energy savings and high efficiency is the motor's permanent magnet technology. Instead of a short-circuit induction motor, the high-efficiency motor incorporates a permanent magnet rotor design with buried magnets, which provides significantly improved efficiency and and overall lower energy consumption compared to a standard induction motor. The permanent magnet motor design eliminates electrical rotor losses, resulting in lower motor currents, improved partial load behavior and reduced temperature heat rise.

Franklin Electric proves that technological progress and ecological responsibility can go hand in hand. With the High Efficiency System, the company offers a forward-looking solution for water pumping that is both economical and environmentally friendly.
