STEEL SHAFT AISI 304-316
KVL fast mixer: the heaviest-duty build in the fast range
The KVL is the fast mixer with the strongest mechanical support: a single or double cast iron bellhousing with DCS angular contact bearings. Angular contact bearings carry radial and axial loads together, so this layout suits larger impellers, long shafts and continuous duty. The three-phase or single-phase electric motor, with 4, 6 or 8 poles, connects to the shaft through a coupling or directly.
The impellers match the EVL: three-blade marine propeller, straight-blade turbine, emulsifier and Cowles impeller, in AISI 304-316 or in PP, PVC or PVDF, on a shaft in AISI 304-316 or C45 coated with PP, PVC, PVDF or PE-HD. What sets the KVL apart from the EVK and EVL is the support: aluminium bellhousing on those models, cast iron with angular contact bearings on the KVL. At the other end of the range, the EV remains the choice for small containers and light duty.
- Large preparation and storage tanks holding corrosive liquids
- Continuous duty in chemical plants
- Cowles dispersion in paint and coating production
- Large tanks in chemical-physical water treatment plants
- Process baths for the textile and detergent industries
Frequently asked questions
When should I move from the EVL to the KVL?
When power, impeller diameter or shaft length push the loads beyond what an aluminium bellhousing should carry, or when the mixer runs continuously for long periods. The cast iron bellhousing with angular contact bearings gives more mechanical margin for the same impeller.
Does the KVL have a gearbox?
In the catalogue configuration the motor drives the shaft through a coupling or directly, with no gearbox. Speed depends on the number of motor poles and can be adjusted with an inverter. If the process needs low speed and high torque, look at the EVR and KVRL slow mixers.
Direct drive or coupling?
Direct drive keeps the assembly compact, while a coupling separates motor and shaft and makes motor replacement easier. The choice depends on available space, power and planned maintenance.
