FAQs
What maintenance is required for Caframo stirrers?
Caframo overhead stirrers are maintenance free. All are manufactured with brushless DC motors, delivering superior efficiency and a long-lasting performance. There are no brushes that need replacing. The only wear parts are the belts of the transmission of the BDC1850, BDC3030 and BDC6015.
Do Caframo stirrers maintain speed (rpm) if the viscosity changes?
Yes. Caframo stirrers are digitally controlled. The speed is kept constant with continuous feedback to the motor. The set speed is maintained as the solution viscosity changes.
Are Caframo stirrers explosion proof?
All Caframo stirrers are built with a brushless DC (BDC) motor which is sparkless. Although this is the case, Caframo stirrers are not deemed intrinsically safe (or explosion proof) as they have not been tested and approved for operation in Class I, Div II requirements.
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.
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 cleanElectropolished parts are used in the following industries:
• Aerospace and automotive
• Water purification
• Food and beverage
• Medical
• Petrochemical
• Pharmaceutical and cosmeticWhat 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).
What shaft diameter will a Caframo chuck accept?
The same sized chuck is used for all Caframo overhead stirrers with the exception of the BDC250 Petite. The chuck will accept a shaft from 5 mm to 10 mm (3/16” to 3/8″). Shafts are typically 9.5 mm (3/8″) or 8 mm (5/16”) in diameter. The BDC250 Petite chuck will accept a 6 mm (0.24”) shaft.

On BDC2010 stirrers LED dots will flash along the bottom of the display.
To disable the Auto Start first ensure the stirrer is powered off. Press and hold the Decrease Button then press the Power Button. The solid or flashing dots on the LED display will turn off to indicate the Auto Start has been disabled.
How do I know if the Auto Start feature is enabled or disabled on my Caframo stirrer?
The stirrer ships from the factory with Auto Start disabled. On BDC250 and BDC2002 stirrers a solid dot will illuminate in the bottom right corner of the LED display to indicate the Auto Start feature is enabled. On BDC2010 stirrers LED dots will flash along the bottom of the display when Auto Start is enabled. When Auto Start is disabled the solid or flashing dots on the LED display are off. Refer to manual for instructions on how to enable or disable the Auto Start feature.
