The KGK series Argal pumps of G3 group of dimensions , are centrifugal pumps designed for vertical installations, with column and volute casing submerged, dedicated mechanical support, motor mounted above the liquid to be pumped. These pumps generate semi axial flow, have single or dual casing with one or two impellers in series. All pumps have the axial suction complete with filter directed downward and delivery pipe flanged and routed upwards through the base plate. SAFE AND DURABLE . Designed to pump aggressive liquids are characterised by solutions apt to deliver long operative life and functionality:
No metallic part wet by the liquid pumped.
Compact electric motor support encasing the flexible joint and the bearing assy, eases use of the pump in restricted quarters common to several applications. lowers the barycentre of the equipment.
No need of sealing systems to contain spilling of liquid pumped.
Different vapour sealing systems meet different operating conditions.
Standard filter with 3 mm free passages screwed on the suction.
MODULAR CONSTRUCTION The range of KGK pumps is manufactured in two dimensional groups made up by different mechanical and hydraulic parts but such that major component are same for all pumps belonging to each dimensional group.
BEARING SUPPORT
Cast iron bearing support dimensioned to support the transmission shaft and all the dynamic loads generated by the pump. it is the privileged solution for heavy duty continuous operations.
Coupling by mean of flexible joint allows to execute maintenance on motor or pumps independently.
CHEMICAL RESISTANCE
All components of the pumps wetted by the liquid pumped deliver excellent chemical resistance and are manufactured in PP or PVDF.
PP polypropylene , thermoplastic U.V. stabilised
PVDF Vynilidene polyfluoride
Pumps can be constructed also with composite material as: With column and delivery pipe reinforced with an external sheeting of FRP (glass fibre reinforced with vinyl ester)
CHARACTERISTICS The KGK series Argal pumps with lengths from 500 to 4000 mm , are centrifugal pumps designed for vertical installations, with column and volute casing submerged, dedicated mechanical support, motor mounted above the liquid to be pumped, downward axial hydraulic suction, tangential outlet connected to the vertical delivery pipe passing through the supplied base plate. Shaft of pumps longer than 2000 mm is supported with additional intermediate bearing.
SHAFT GUIDE BUSHINGS Shaft guide bushings are available in the following combination of materials:
Glass reinforced PTFE over Alumina Ceramics for general purpose use included liquid containing crystals and floccules;
Silicium carbide over Silicium carbide for liquid laden with significant qty. of solids or to cope with aggressive fluorinated liquids or strong alkali.
Shaft guide bushings are lubricated directly with the liquid pumped or through external flushing with fresh water in case the liquid to be pumped is laden with solids.
VAPOUR SEALING The vapours developing in the pump are contained by mean of a dry vapour seal mounted in the proximity of the base plate and active in static and dynamic conditions. This standard seal counters pressure up to 60 mbar. Higher pressures require other optional dry constructions or mechanical seal flushed with liquid pumped.
PERFORMANCES AND VERSATILITY
Each pump model can be configured with different electric motors of increasing rated power , to met the power demand of liquids with increasing specific gravity. Standard electric motors comply to IEC and are rated 400Vac +/- -5%, multi frequency 50-60 Hz, tropicalised insulation, protection class IP 55 and class F insulation. On request are available other choices of voltages and protection. The speeds for the 2 poles motors are either 2900 rpm at 50 hz or 3500 rpm at 60 hz, for the 4 poles motors are 1450 rpm at 50 hz or 1750 rpm at 60 hz.. CONNECTIONS
PP execution threaded BSP and on demand, NPT or flanged ISO/ANSI;
PVDF execution flanged ISO o ANSI.
MAINTENANCE KGK pumps are designed to by easily maintained by end user or by distributors diffused worldwide with use of minimal common tools.
