STEEL SHAFT AISI 304-316

EVK-G fast mixer: when the shaft needs its own support

The EVK-G follows the fast mixer principle, a compact impeller at high speed for thin liquids, but adds an aluminium bellhousing with a bearing between motor and shaft. Motor and shaft are joined by a self-aligning 7075 aluminium coupling. The bellhousing bearing takes the radial loads produced by the impeller, which would otherwise sit on the motor bearings alone. Shaft length is set according to the height of the container or tank, and the mounting plate can be adapted to the installation.

Compared with the EV, which carries the impeller directly on the motor shaft, the EVK-G is the option for taller containers and stiffer mountings. The EVL uses the same aluminium bellhousing but can take a double bearing, while the KVL moves to a cast iron bellhousing with angular contact bearings. The EVK-G accepts three-phase or single-phase 4, 6 and 8-pole electric motors or a pneumatic motor, a shaft in AISI 304-316 or C45 coated with PP, PVC, PVDF or PE-HD, and a three-blade marine propeller in AISI 304-316, PP, PVC or PVDF.

Frequently asked questions

Why choose the EVK-G over the EV?

When the shaft has to reach deeper, the impeller works further from the motor and shaft deflection grows. The bellhousing bearing and 7075 coupling on the EVK-G keep these loads away from the motor and hold the shaft in line. For low containers and light duty the EV remains the simpler choice.

Can the EVK-G take a Cowles impeller?

Yes. Besides the three-blade propeller (500-1500 rpm), the range of impellers includes the Cowles disc (300-3000 rpm), the straight-blade Rushton turbine (300-1400 rpm) and the emulsifier impeller (500-2000 rpm). The propeller is the standard fit; the others are selected to suit the process.

When does the pneumatic version make sense?

Where compressed air is available and an electric motor above the tank is best avoided, for example in wet areas or where aggressive vapours are present. For hazardous areas, ATEX certification is assessed on request.
