Close Coupled Pumps equipped with a motor with built-in frequency converter are multi-purpose pumps suitable for a variety of different applications demanding reliable and cost-efficient supply. Close Coupled Pumps are used in five main fields of applications: Water supply, industrial pressure boosting, industrial liquid transfer, HVAC (heating, ventilation and air-conditioning), and irrigation. They also offer a smaller footprint that saves on site installation costs and saves space so they are an ideal choice for use in complex machinery or in confined spaces.
