The combined use of pumps manufacturer Grundfos’s range of submersible pumps, external frequency converters and multi- pump controller systems ensures ease of use of pump systems and that efficiency increases.

“Water suppliers can safely expect fast, local assistance if a situation arises that requires repair or replacement, as we are well represented throughout the world by local distribution outlets and service partners,” states Grundfos.

Further, Grundfos asserts that its integrated solutions can improve groundwater intake with an external frequency converter and a multi- pump controller to control multiple submersible pumps.

“This combination is a feasible option for any water supply system, especially small to medium-sized operations.”

The company points out that its stainless steel submersible pumps have a good record in terms of reducing life cycle costs.

“A steady course of continuous improvement has significantly improved the pump’s hydraulics. The pump’s motor has also been electrically enhanced to ensure the pump that it is fitted to operates highly efficiently,” says Grundfos.

Moreover, the company states that the benefits of frequency converters are well established as a significant strategy to further reduce life cycle costs.

“Energy consumption is significantly reduced, and regulating pump operation in times of low demand has a corresponding effect on wear, thus further enhancing reliability.”

Meanwhile, the company notes that its new external frequency converter has all the functionalities needed for running pump applications.

The company’s external frequency converter is preprogrammed for submersible pumps (and any other Grundfos pump of up to 250 kW), specifically for pumping operations.

Ensuring Reliability

Further, Grundfos explains that modern water suppliers aim to provide a reliable service to households and businesses.

“Although clean and safe water is always the first priority, cost efficiency is a parameter that is of pressing concern for water suppliers and their stakeholders. Life cycle cost analyses – not least in relation to pumping installations – are a clear illustration of how this concern has transformed into practical initiatives,” the company states.

The company notes that, in the past 10 to 15 years, control and monitoring systems have increased the potential for improving both.

“However, integrating the many components involved has at times been discouragingly complex and costly,” Grundfos laments.

However, Grundfos points out that it has sought to tackle such challenges by engineering control and monitoring units that are dedicated specifically to pumping systems.
“The key has been to integrate components to offer complete systems that are pre-engineered to work together. “Interface issues that require time-consuming and often troublesome programming are replaced by simple start-up wizards that offer a step-by-step guidance through the setup of the system,” the company says.

Grundfos believes this integrated engineering approach can put an end to the challenges of complex installation.
