When to choose the EVR slow mixer
The EVR is the simplest vertical slow mixer in our range. Its shaft, made of AISI 304-316 stainless steel or C45 steel coated with PP, PVC or PVDF, is keyed directly to the gearbox, with no intermediate lantern and no support bearing. It can be driven by an electric or a pneumatic motor. Choose it when shaft loads are moderate and you want a compact unit with few parts to inspect during maintenance.
Like every slow mixer, the EVR is designed for medium and high viscosity liquids and for processes that need steady circulation without excessive turbulence. When loads increase, the EVRK and EVRL add an aluminium lantern with a bearing; for heavy loads and several impellers on one shaft, the KVRL is the next step.
- Flocculation in chemical-physical water treatment plants
- Neutralisation of acidic or alkaline effluents
- Polyelectrolyte solution preparation
- Mixing of medium and high viscosity fluids in polypropylene or PVC tanks
- Gentle homogenisation of corrosive chemical solutions
Frequently asked questions
Which impellers can be fitted to the EVR?
The EVR uses a four-blade impeller with inclined or straight blades, made of AISI 304-316 stainless steel or PP, PVC, PVDF or PE-HD. Inclined blades create a mixed flow with a prevailing axial component, which suits flocculation; straight blades add radial action. The data sheet gives 10 to 380 rpm for the inclined blade impellers.
Can the EVR be mounted on a polypropylene tank holding corrosive liquids?
Yes. The coated shaft and the impeller are available in PP, PVC or PVDF, selected according to the chemical and the operating temperature. A single or double flushed mechanical seal can be fitted on request.
When should I move up to the EVRK or EVRL?
When the loads transmitted by the shaft to the gearbox increase, for example with a longer shaft or a larger impeller. The EVRK and EVRL add an aluminium lantern with a bearing, for medium and high loads respectively. Our engineering team selects the configuration from your tank and fluid data.
