Bottom-Entry 4-Blade Pitched Magnetic Stirrer

As a seasoned manufacturer specializing in bottom-entry mixing solutions, I understand the unique challenges you face when selecting agitated equipment for sensitive or pressurized systems. Our Bottom-Entry 4-Blade Pitched Magnetic Stirrer (ACJ series) is not just another process stirrer—it is a precision-engineered workhorse upgraded from the CJ series, optimized for maintenance convenience and compliance to meet the rigorous demands of high-cleanliness and high-compliance industrial production environments.

Why a bottom-entry design? Unlike traditional top-mounted stirrers, the bottom-entry configuration eliminates the need for overhead clearance and allows for seamless integration into fully enclosed vessels. Designed with a bottom-entry disassembly structure, the 4-blade pitched impeller and internal tank components can be assembled or disassembled entirely from the bottom of the tank without requiring any top-side operations. This effectively solves the challenge of equipment disassembly in fully enclosed tanks without manholes, significantly reducing disassembly difficulty and operational risks.

The core sealing structure features a detachable containment shell and tank design. The welding method of the tank connection flange fully complies with pressure vessel standards, which ensures exceptional sealing performance and facilitates direct maintenance if a containment shell failure occurs. While achieving absolute zero leakage, the proprietary sealing form ensures a dead-leg-free cleaning process, perfectly accommodating CIP (Clean-in-Place) and SIP (Sterilize-in-Place) systems. Furthermore, this angled-blade assembly adapts efficiently to the agitation and mixing of various media, operating with proven stability even when material volumes are low.

Procurement considerations: When you source from us, you eliminate the hidden costs of shaft seals, leak repairs, and contamination risks, while drastically improving maintenance efficiency. This equipment is highly applicable to reaction tanks, fermentation tanks, formulation tanks, and storage tanks for large-volume parenterals (LVPs), vaccines, blood products, insulin, oral liquids, and other high-purity scenarios. It is especially ideal for working conditions where there is no operating space at the top of the tank and no manholes.

Don't compromise on process integrity or regulatory compliance. Choose the magnetic agitation system that protects your product, your personnel, and your reputation.
