Wilo USA, a provider of pumps and pump solutions for water management, building services and groundwater, has extended its range of models for the Wilo-Stratos GIGA line of centrifugal pumps to include three and four inch models, bringing the total offering of the line to 28 models.

The Wilo-Stratos GIGA is an in-line circulator with ECM technology that is designed for use in hot water heating systems, air conditioning, closed cooling circuits, industrial circulation and solar and geothermal systems.

Don Kahn, Senior Product Manager said: “The combination of its high-efficiency EC motor, optimized hydraulic design and the ability to self-adjust to system demand makes it the most efficient in-line pump in its class. Coupled with the ‘Green Button’ technology and building communications options, commissioning of the pump cannot get any easier.”

With heads up to 167 ft and flows to 550 gpm, the GIGA also features high corrosion protection due to its coating, enabling it to withstand high pressure and weathering. The new ranges of the Wilo-Stratos GIGA are now available by contacting a local Wilo USA representative.
