How do I choose a mixing impeller?
To choose an impeller the volume of the mixture, the size of the mixing vessel and the viscosity of the mixture should be known. The diameter of the mixing blade should measure one third of the diameter of the vessel, and be placed a distance of one third the diameter of the vessel up from the bottom of the vessel.
For thicker mixtures, use a square or “U” shaped anchor paddle. These paddles have more surface area to contact the thick product being mixed. Because thicker mixtures are usually mixed more slowly a paddle diameter closer to the full diameter of the vessel can be used so that the product close to the edge of the vessel is mixed. (A150, A250 are examples of square blade paddles; U022, U044, U055, U510 or A183 are examples of anchor paddles).
The paddle I need is not listed on your website. Can you make what I need?
We are happy to make custom paddles. Email or fax a drawing showing the specifications you need and a quotation outlining a part number, price and delivery will be emailed or faxed back for approval.
How do I reduce the vortexing I am experiencing with my propeller?
A baffle can be used in the vessel to reduce vortexing or the stirrer can be rotated slightly in the clamp so that the mixing shaft is not perpendicular. With the impeller on an angle, the vortex is broken and the introduction of air is minimized.
What is electropolishing?
All stainless steel impellers and blades from Caframo are electropolished. Electropolishing is an electrochemical treatment performed on stainless steel to obtain a smooth, corrosion-resistant finish. This process also passivates the stainless steel by removing elemental iron and increasing the chromium concentration on the surface and nickel just beneath. The result is a chemically inactive part. Note that the process does not coat the part.
Along with the improved appearance, electropolishing provides the following benefits:
• Reduces stress-related cracking and metal fatigue
• Increases the life span of the part
• Optimizes sterilization as parts are easy and quick to clean
Electropolished parts are used in the following industries:
• Aerospace and automotive
• Water purification
• Food and beverage
• Pharmaceutical and cosmetic
What are all the parts I need to start mixing?
To start mixing the following parts are needed: stirrer motor, clamp, stand and mixing impeller. Go to the “Products” section to find the stirrers and accessories available. The Caframo BDC250 Petite stirrer comes as a package. It includes the stirrer motor, integral clamp, stand, and two mixing impellers (axial and straight blade).
Where can I find an impeller for the 1540?
Do the casters lock on the A118 stand?
The A118 stand has four swivelling casters, two of which have brakes to solidly lock the stand in place.
