Grundfos 99442959 Range 70 => 155 kW S2.105.250.650.8.70H.D.538.G.N.D.511
Product code: 99442959
EAN Number: 5713829208308
The pump is designed for intermittent and continous operation. The cooling jacket ensures that the pump can operate submerged or dry installed without motor cooling. The two-channel impeller handles solids up to 105 mm in size. A SmartTrim impeller clearance adjustment system makes it possible to maintain maximum performance throughout the lifetime of the pump. To facilitate easy transportation as well as installation on-site, the pump is fitted with a robust lifting bracket. For installation on auto coupling, the Grundfos SmartSeal gasket system provides a leak-proof connection. Pipework connections are via a DIN flange.
