Tank Magnetic Mixer
Bottom mounted agitation with a static welded seal instead of a mechanical one, for vessels where leakage is not acceptable.
Overview
What This Pump Does
The magnetic agitator is a mixing device for stainless steel reaction and liquid compounding tanks. Static sealing through a welded isolation sleeve replaces the dynamic mechanical seal, which removes the leaking problem that mechanical seals bring to sterile and hazardous vessels.
The mixing unit is installed at the bottom of the vessel, so it can mix even a small quantity of liquid. Construction is simple, easy to dismantle and easy to clean with no dead space, and the design is aimed at pharmaceutical, biological engineering and food vessels following GMP practice.

Key Benefits
Why A Magnetic Agitator Instead Of A Shaft Seal
Sealed By Welding
A welded isolation sleeve is a static seal, so there is no rotating seal to leak or wear.
No Dead Space
Simple construction with no dead space, easy to dismantle and easy to clean for validation.
Mixes At Low Level
Bottom mounted installation means mixing continues with only a small amount of liquid in the vessel.
Built For Hazardous Contents
Intended for places needing high standard sealing, such as inflammable, explosible or leak prone contents.
Application Scenarios
Where It Is Installed
Compounding Vessels
Mixing in stainless reaction and liquid compounding tanks in pharmaceutical production.
Flammable Product
Vessels holding inflammable or explosible liquid where a leak path is unacceptable.
Biological And Food Processing
Food and biological engineering vessels designed around GMP requirements.
Who It Is For
- Pharmaceutical and biotech manufacturers
- Fine chemical producers
- Food plants with sterile vessels
- Vessel fabricators specifying agitation
Problems It Solves
The mechanical seal leaks
Replacing a dynamic seal with a welded sleeve removes the leak path completely.
Cleaning validation fails around the seal
No dead space and easy dismantling make the vessel cleanable where a stuffing box would not be.
Low batch volumes will not mix
Bottom entry keeps the impeller in the liquid when the level is low.

Compared With Other Options
| Top entry agitator with mechanical seal | A top entry unit is cheaper but adds a rotating seal at the top of a sterile vessel. |
|---|---|
| High shear emulsifier | An emulsifier applies shear to refine a product. This agitator provides gentle mixing without a seal. |
Use Guide
Fitting A Bottom Magnetic Mixer
Confirm The Vessel
Volume, diameter, lowest working level and the nozzle in the dished bottom.
Check Pressure Duty
Working pressure must sit inside the 0.09 to 0.8 MPa selection range, including any sterilisation cycle.
Choose The Drive
Vertical or horizontal arrangement, with a speed reducer where slow mixing is required.
Plan Cleaning
Dismantle and clean at planned intervals, using the simple construction the design provides.
Answers
Tank Magnetic Mixer FAQ
How does it seal?
Static dead sealing through a welded isolation sleeve replaces the dynamic mechanical seal.
What working pressure is available?
0.09 to 0.8 MPa for selection, with a speed reducer and vertical or horizontal types available.
Can it mix a nearly empty tank?
Yes. The mixing unit is installed at the bottom so it can mix small quantities.
Is it suitable for GMP vessels?
It is designed for pharmaceutical, biological engineering and food industries in line with GMP practice.
What surface finish is used?
Mirror or matt polish to Ra below 0.8 um on 304 or 316 wetted parts.
