EVRK slow mixer: applications and selection
The EVRK keeps the layout of the EVR, with the shaft keyed directly to the gearbox, and adds a mechanical support made of an aluminium lantern for medium loads with a bearing. The lantern takes up the radial loads generated by the impeller, so the gearbox runs under steadier conditions when the impeller is larger or the fluid offers more resistance. Electric or pneumatic motors are available.
Compared with the EVR, the EVRK also widens the impeller choice: besides the four-blade impeller with inclined or straight blades, a high-flow version is available. This makes it a practical middle ground between inclined blade mixers for flocculation and set-ups aimed at circulating large volumes. The mounting plate is sized to suit the installation.
- Flocculation and coagulation in chemical-physical water treatment
- Neutralisation in reaction tanks
- Polyelectrolyte preparation and storage
- Keeping solids in suspension at low speed
- Mixing corrosive fluids of medium to high viscosity
Frequently asked questions
What is the difference between the EVRK and the EVRL?
Both have an aluminium lantern and a bearing. The EVRK is designed for medium loads and the EVRL for high loads. Shaft construction, materials and impeller options are the same.
When is a high-flow impeller better than inclined blades?
A high-flow impeller moves large volumes with low shear and suits circulation and solids suspension. Inclined blades give a more versatile mixed flow, well suited to flocculation and polyelectrolyte. Both are listed for 10 to 380 rpm.
Which materials are available for the EVRK?
Shaft in AISI 304-316 stainless steel or C45 steel coated with PP, PVC or PVDF; impeller in AISI 304-316 stainless steel or PP, PVC, PVDF or PE-HD. A single or double flushed mechanical seal is available on request.
