Boston Shearpump® Inline High Volume Mixer for Particle Size Reduction


The Boston Shearpump (BSP) provides high throughputs at moderate to high shear rates, surpassing the capabilities of conventional shear pumps and colloid mills. The BSP is ideal for inline mixing of solids or powders into viscous liquids and offers consistent and repeatable shear capability. The BSP is for specific mixing requirements where "texturizing" of viscous products is required, and it meets the toughest hygienic standards including 3-A TPV compliance.

Designed to run 24/7, the Boston Shearpump will mix, disperse, emulsify, pulverize, macerate, crush, homogenize, and reduce solid particles at high volumes, and can withstand uneven flow patterns, jolts, and pressure fluctuations.

Wet milling with rotor-stator equipment can provide many advantages. In the fooddairybeverage and other industries, particle size reduction is important and the BSP can mill soft particles down to <10 micron, or hard particles down to 10-20 microns in just a single pass at high production rates. It can also be used to precondition product going through a high-pressure homogenizer, improving total product quality while increasing homogenizer capacity and reducing homogenizer maintenance costs.
