Polished Side-Entry Agitator

Updated: 2026-09-15

Overview

The Polished Side-Entry Agitator is a specialized mixing device installed through the sidewall of tanks or vessels. Its polished surface meets sanitary standards, making it ideal for industries with strict hygiene requirements like pharmaceuticals and food processing. The side-entry design allows for flexible installation in confined spaces or large tanks where top-mounted agitators are impractical. It ensures uniform mixing while minimizing dead zones in the liquid medium.

Structure and Working Principle

This agitator consists of a motor, shaft, and impeller, with a polished stainless steel construction for easy cleaning. The impeller generates axial or radial flow patterns depending on the blade design, ensuring efficient mixing. The side-entry angle (typically 15°-45°) is engineered to create optimal turbulence while reducing mechanical stress on the shaft. Sealing systems like mechanical seals or lip seals prevent leakage in pressurized applications.

Key Features

Polished surfaces (Ra ≤ 0.8μm) prevent bacterial growth and facilitate CIP (Clean-in-Place) processes. The stainless steel material offers corrosion resistance for acidic or alkaline environments. Customizable impeller designs (e.g., propeller, turbine, or paddle) cater to specific viscosity ranges. Some models include variable speed controls for process optimization.

Application Areas

Widely used in chemical reactors for polymerization or crystallization processes. In pharmaceuticals, it ensures uniform blending of active ingredients. The food industry employs it for mixing emulsions, sauces, or dairy products. Cosmetic manufacturers use it for lotions and creams requiring gentle yet thorough mixing.

Maintenance and Precautions

Regular inspection of seals and bearings prevents downtime. Lubrication schedules vary by model but are critical for long-term performance. Avoid abrasive media that may damage the polished surface. Ensure proper alignment during installation to prevent shaft deflection or vibration issues.

B2B Procurement Guide

Specify tank dimensions, fluid properties, and sanitary requirements when sourcing. Leading manufacturers offer ATEX-certified models for explosive environments. Compare motor efficiency ratings (e.g., IE3 or higher) for energy savings. Request material certificates (e.g., ASTM A240) for traceability in regulated industries.
