The K2 series are centrifugal pumps designed for vertical installations, with column and volute casing submerged. The motor is mounted above the liquid pumped; the axial suction pipe is placed downward whereas the tangential and outlet pipes are passing through the base plate.
The pump shaft can be long up to 4000 mm. Above 2000 mm, the shaft is held by an additional intermediate bearing.
Three versions are available according to the column size and the performance: KGK G1 -2 (radial volute) and KGK G3 (axial fumes)
Capacity: up to 275 m3/h
Length: between 500 and 4000 mm
Motor power: kW 0,55 ÷ 45
Wetted parts: PP or PVDF.
Column: PP or PVDF or PP + FRP or PVDF + FRP
ISO 9906:2012 standards
KGK pumps are complying with ISO 9906:2012 standard, Level 2.
K2's KGK pumps were thought for pumping aggressive liquids and thus were designed to offer a longer life cycle and greater functionalities: there is no need for sealing systems to avoid liquid spillings, various choice of the vapour sealing systems for fitting applications.
The gases developed inside the pump are contained thanks to a dry vapour steam seal mounted nearby the base plate and always active, whether the pump operates or not. This standard seal counters pressure up to 60 mbar. For higher pressures, a waterproof construction or mechanical seal flushed with the pumped liquid is necessary.
