Product Description

The Wilo-Atmos GIGA-B is a dry rotor pump with a modular design, suitable for heating, air conditioning, and refriger applications in large buildings.

 Product Description                                                                    

The Wilo Atmos GIGA-B is a compact, horizontally mounted end-suction centrifugal pump, especially suitable for water supply in various types buildings. The main dimensions comply with the requirements of EN733.
Flow range  : <1000m³/h
Lift range : ≤150m
Max.operating pressure at different fluid temperature : 16bar
Temperature range : -20ºC~+140ºC
Aplication field : The B-series horizontal end suction pump can be widely used in water supply systems, circulation systems for heating or air conditioning, irrigation systems, conveying hot and cold water that does not contain abrasive substances in heating, cold water, and cooling water systems (in accordance with VDI2035 standard)

Summary                                                                       

Wilo-Atmos GIGA-B With optimized hydraulic efficiency, the pump is characterized by low life cycle costs. All cast parts are with an anti-corrosion electrophoretic coating, ensuring long service life. The standard pump feet and "pull-back" design, as well as the cartridge mechanical shaft seals for large pump sizes (37kW/4-pole and above), greatly reduce the installation and maintenance burden on the customer's side.

Your advantages                                                             
  

  

• State-of-the-art pump hydraulics and usage of IE3/IE4 motors ensure energy savings
• Diverse impeller materials, several motor options and various mechanical seals allow for universal use in a multitude of applications
• Easy installation due to standard pump support feet and optional supporting block
• Easy maintenance and user-friendly design with optional back pull-out design and cartridge mechanical seal for large pump types
• Cataphoretic coating of all cast iron components ensures high resistance to corrosion and long service life
• Meets user requirements due to performance and main dimensions in accordance with EN 733 (DIN for end-suction pumps)

Technical data                                                                 

• Permissible temperature range of -20 °C to +140 °C
• Mechanical seal for pumping water up to Tmax = +140 °C. Up to T ≤ +40 °C, a glycol admixture of 20 % to 40 % by volume is permissible. An alternative mechanical seal must be provided for water-glycol mixtures with a glycol content of > 40% to max. 50% by volume and a fluid temperature of > +40 °C to max. +120 °C or other fluids that differ from water. When using water-glycol mixtures, the use of an S1 variant with a corresponding mechanical seal is generally recommended.
