The Wilo Atmos GIGA-N series dry rotor pump is designed for use as a circulating pump in the field of building technology.
Product Description
The Wilo Atmos GIGA-N is a horizontally mounted end suction centrifugal pump with a volute casing for horizontal installation. Performance and comply with EN 733.
Flow range : <1000m³/h
Lift range : ≤150m
Max.operating pressure at different fluid temperature : 13bar/16bar
Temperature range : -20ºC~+140ºC
Aplication field : The N series horizontal end suction centrifugal pump can be widely used in heating, air conditioning systems, circulation systems, water supply systems, fire sprinkler systems, etc.Suitable for circulation, transportation, and pressurized water supply. The medium used for transportation must comply with VDI2035 standards for hot water, water ethylene glycol mixture, cooling water/cold water, and industrial water
Summary
Wilo Atmos GIGA-N is a universal standard pump with a long service life and is an entry-level product for dry rotor pumps.
The wide range of motors and materials to choose from plus its wide temperature range from -20 to +140 °C make it a real all-rounder for a whole host of different applications.Designed specifically for continuous operation, the pump also boasts a long service life thanks to its corrosion-resistant coatings and maintenance-free roller bearings. If maintenance is required, the spacer coupling ensures the mechanical seal can be replaced as quickly as possible. The speed of the Wilo-Atmos GIGA-N is controlled by a Wilo-EFC converter. It can be fitted with temperature and vibration monitoring for the pump bearing so that impending breakdowns can be recognised in good time.
Your advantages
- The high overall efficiency through improved hydraulics and the use of IE3/IE4 motors enables energy savings
- Suitable for drinking water supply (compliant with ACS and UBA)
- Cataphoretic coating of all cast components for high resistance to corrosion and long service life (not available for drinking water versions)
- Universally usable thanks to standardised dimensions, a range of motor options and impellers made of different materials
- Easy maintenance thanks to user-friendly spacer coupling in back pull-out design
- High operational reliability thanks to improved impeller construction for pressure reduction
