Atmos GIGA NF
Norm pump
- High reliability and durability thanks to cataphoretic coating of all cast components, bronze impeller and stainless steel slip rings for high corrosion resistance
- User-friendly “back pull-out” design for easy maintenance
- Different drives depending on individual requirements
- Valve at pump outlet ensures minimum water flow to protect against overheating
- Easy and safe transport, installation and maintenance thanks to solid construction on base frame
Design
Single-stage, horizontal centrifugal pump for firefighting water supply according to EN 733 and VdS 2100-07 for installation on a base frame.
Depending on the version, consisting of one pump mounted on base frame with spacer coupling or universal joint and electric or diesel motor.
Application
Automatic water supply for fire-extinguishing systems with sprinklers in domestic, commercial and administration buildings, hotels, hospitals, shopping centres, office blocks and industrial buildings.Liquid
undefinedEquipment/function
- One horizontal baseplate pump according to VdS 2100-07 with IE4-equivalent standard motor or diesel motor.
- Base frame made of epoxy-coated steel.
