KRK - Coaxial agitator

KRK coaxial agitator features two different impeller systems for parallel mixing. The KRK has two interdependent agitator shafts with a different number of revolutions that move in opposite directions. The faster agitator shaft is supported in the slower hallow shaft of the geared mixing unit. The KRK series is primary suitable for the dispersing of highly viscous media. The heat transfer is promoted. Explosion-proof series certified to ATEX Directive 2014/34/EU zone 0 and zone 1.

GRV - Geared agitator with variable speed gear unit The GRV series can be used in versatile manner. It is equipped with a mechanically variable speed variation drive with drive ratings of up to 11.0 kW. Furthermore it can be supplied with geared drives that have a standard output speed of between 1 and 1,750 rpm. The speed is adjustable with a hand wheel. The agitator shaft of the GRV series geared agitator is directly mounted on the shaft of the mechanical speed variator or with additional speed reduction (all before mentioned solutions possible). The agitator shafts are balanced for concentric run after assembly of the mixer. According to the specific mixing task, the GRV series can be supplied with matching mixing elements and various seals.

GRK - Geared agitator with helical bevel geared drive The GRK series geared agitator equipped with a helical bevel geared drive with reinforced bearing can be used for a wide range of applications due to its low installation height. This ow installation height can be achieved thanks to the horizontal position of the drive. The agitator shaft of the GRK series is directly mounted in the hollow shaft of the gear and, upon request, this agitator shaft can be divided by flanged coupling. After assembly of the mixer, the agitator shafts are balanced for concentric run. The GRK series features shaft lengths of up to 6,000 mm and drive ratings of up to 75.0 kW. It has a standard output speed of 1 to 250 rpm. According to the specific mixing task, the GRK series can be supplied with matching mixing elements and various seals. Upon request, we supply the GRK series with frequency controlled drives that have drive ratings of up to 7.5 kW. Type test certificate for explosive zone 0.

GRW - Geared agitator with worm geared drive The GRW series is suited for a wide range of applications thanks to shaft lengths of up to 3,000 mm and drive ratings of up to 5.5 kW. It has a standard output speed of between 10 and 200 rpm. Low installation height thanks to horizontal position of the drive. The agitator shaft of the GRW series geared agitator is directly mounted in the hollow shaft of the worm geared drive. Additional flanged or clamp couplings can be implemented upon request. The agitator shafts are balanced for concentric run after assembly of the mixer. According to the specific mixing task, the GRW can be supplied with matching mixing elements and various seals. Upon request, we supply the GRW series with frequency controlled drives.
