The KGK 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.

Overview

The KGK 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: G1 -2 (radial volute) and 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

KGK 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 dry construction or mechanical seal flushed with the pumped liquid is necessary.

Applications

The FRONTIERA range is the technical solution for offering a great balancing between its elements. All components in contact with the pumped liquids are realised in PP or E-CTFE and the pump is covered with a solid armour made of AISI 316 for making the pump more robust and chemically more resistant. Thanks to the materials used, Frontiera ensures the highest chemical resistance to the most aggressive liquids.
