HHB Series Powder-Liquid Mixer Pump

Overview

The HHB Series Powder-Liquid Mixer Pump is a high-performance industrial solution specifically engineered for continuous, inline wetting, dispersion, and dissolution of dry powders into liquids. Combining an ergonomic vertical hopper with a high-shear centrifugal dispersion mechanism, it rapidly draws dry or granular ingredients into the liquid stream. This process eliminates common mixing bottlenecks such as lumping, floating powders, and slow processing times.

Key Features & Advantages

• High-Efficiency Inline Mixing (No Lumping, No Dust): Equipped with a large-capacity top hopper, the system generates a powerful fluid suction and shear effect. Powders are instantly wetted and dispersed upon entering the pump chamber, preventing agglomeration, „fish-eyes,“ or unmixed centers.

• Sanitary Design for High Standards: All contact parts are manufactured from premium sanitary-grade stainless steel (SUS304 or SUS316L) with mirror-polished surfaces. Designed without dead corners, the unit is fully compliant with CIP (Clean-in-Place) and SIP (Sterilization-in-Place) procedures for food, dairy, and pharmaceutical standards.

• Quick-Release Modular Construction: Utilizes quick-fit tri-clamp technology throughout the assembly. The pump body and piping can be disassembled, inspected, and cleaned without specialized tools, minimizing operational downtime.

• Robust & Compact Footprint: Built on a heavy-duty stainless steel base with vibration-damping feet and a protective motor shroud, this compact unit offers high stability and a long service life in continuous production environments.

Applications

• Food & Beverage: Reconstituted milk powder, sugar syrup preparation, starch dispersion, stabilizer/gum (xanthan, carrageenan) dissolution, and additive blending.

• Pharmaceuticals & Biotech: Buffer preparation, nutrient media dissolution, and active ingredient slurry blending.

• Personal Care & Cosmetics: Shampoo and liquid soap formulation, lotion base preparation, and pigment/fragrance inline addition.

• Fine Chemicals: Polymer/polyelectrolyte dissolution, pesticide formulation, and dye/pigment dispersion.

Typical Application 1

Can be achieved on fast-dissolving of a variety of powder products, dealing mainly with the solution, which has a solid content of not more than 15%. Usually used in the rapid dissolution process of milk powder, pectin, additives, sugar, and other materials.

Typical Application 2

Increasing the centrifugal pump between the mixer and the make-up tank is in order to feed the mixer as expected. This configuration can handle relatively high solid content of solution, high-speed liquid through the centrifugal accelerates the solution processing of dry powder. Mainly used in the processing of the final solution with solids content of 25% or less

Typical Application 3

This system is equipped with two sets of rotor pumps; the rotor pump has a relatively large advantage in the process of delivering materials containing the viscosity, and has a relatively high pressure. This system is designed to handle high solids content of mixed solutions, especially perfect for dealing with solutions with solids content of 50% or more.

Operating Principles

• The mixer primarily consists of a casing and a centrifugal pump impeller, both of which are mounted vertically. The suction side has a double-wall tube that keeps the inlet of solids separate from that of liquids, thus avoiding the formation of flocculent before the material enters the casing.
• The liquid enters the mixing chamber at a high velocity, thereby creating a vacuum at the center of the impeller, which causes the suction of the solids. The fall of the solids can be regulated by means of a valve situated at the bottom of the hopper. It is important to keep low pressure at the suction and at the discharge sides of the blender. Avoid cavitation. Thus, a feeding pump must be provided only for the applications that really require it (considerable pressure drops at the suction side, high viscosity products, etc.). Please keep in mind that the suction capacity will decrease.
• When discharge pressure is high, a centrifugal pump needs to be fitted to the discharge side of the blender.
• For viscosity above 500 CP, the feeding pump and the discharge pump must be positive-displacement pumps
