Submersible pumps are said to offer a variety of advantages for demanding applications such as sump pumping, wastewater management and numerous industrial processes.

IPR rental development manager Ruaan Venter says that while engineers have various solutions at their fingertips, submersible pumps often stand out especially when compared to vertical spindle pumps.

“First and foremost, submersible pumps are known for their superior energy efficiency,” Venter says. “This elevated efficiency not only makes them outperform their vertical spindle counterparts, but it also leads to significant cost savings in the long run.”

Submersible pumps offer a particular advantage in space-constrained dewatering setups, as direct placement in the fluid being handled means there is no need for extended piping or additional external infrastructure. The underwater operation shields of the pumps shield them from many external factors, adding to the unit’s reliability.

Venter says that submersibles also offer lower maintenance, with fewer moving parts than vertical spindle pumps, making the units less prone to wear. Reduced wear translates into more dependable performance, ensuring a smoother operational experience.

The fully submerged operation of the pumps eliminates problems such as cavitation or airlocks, which can be found in vertical spindle pumps. The submerged state ensures a consistent and smooth pumping process, offering enhanced reliability. The pumps’ positioning underwater also helps to diminish risks linked with rotating parts and potential leaks.

“But it's not just about efficiency and reliability. Submersible pumps also promise a quieter operational experience. Their underwater functioning naturally dampens sound and curtails vibrations, offering a noise-free solution,” he continues.

Submersible pumps are designed to process different types of fluids, included those with abrasive solids. This makes them suitable for a range of applications, including the pumping of sewage, wastewater pumping applications, dewatering in mining operations or sumps in buildings or other structures.

Many submersible pumps can be customised to avert fluid leaks, ensuring they operate with minimal environmental impact, helping companies adhere to ecological regulations and sustainability goals. In addition, the pumps can be adapted to ensure a fluid handling system that aligns with specific operational demands, depending on the depth requirements.

IPR is the master distributor for the full range of Atlas Copco submersible dewatering pumps and the Toyo range of heavy-duty slurry pumps. The company highlights its extensive reference base and says it offers pumps for outright purchase or on a rental basis.
