Product Features

The Hydrostar MKIII has been redesigned to provide a substantially quieter operation with even higher flow rates and higher head than the previous Hydrostar models. Waterco has improved the hydraulic efficiency of the pump with the introduction of an internal volute. The volute’s hydraulic design provides a natural balanced water flow and reduces hydraulic turbulence.

Purposed built for commercial sized swimming pools, Hydrostar MKIII pumps efficiently deliver high flow rates and incorporate an innovative quarter lid & lock ring assembly for easy maintenance. The pump body is manufactured utilising state of the art engineering plastic moulding with a single piece strainer pot for extra strength and an in built volute for maximum performance. A high grade 316 stainless steel mechanical seal is incorporated for extra protection against corrosion. e.g. chlorinated water, ozone, iodine, Baquacil, bromine and saltwater.
