LHDM900 Series
Laboratory High-Speed Shearing Dispersing Emulsifier · Analog & Digital Models
The LHDM900 series (A / D) high shear homogenizer is driven by a compact series-excited miniature high-speed motor. It is suitable for mixing low to medium-high viscosity liquids, particle size reduction, emulsification, and dispersion in laboratory or pilot plant environments. The system integrates a high-density die-cast aluminum body, refined stainless steel working head, and precise speed regulation – available in analog stepless (LHDM900A) or digital touch-screen (LHDM900D) control.

⚙️ High shear working principle & key features
Rotor-stator homogenizing principle
Mechanical shear: High-speed rotor draws liquid/particles into the precision stator, generating intense hydraulic shear, turbulence, and cavitation.
Emulsification & dispersion: Effective reduction of droplet/particle size down to submicron range for stable emulsions and suspensions.
Continuous process: Recirculation or batch operation ensures uniform mixing and homogenization in the vessel.
Interchangeable stators: Three different stator screens (5/20/50 mm²) tailor shear intensity for low to high viscosity applications.
Superior drive & safety design
Series-excited micro motor: High output power in compact structure, safe and reliable for continuous lab use.
Die-cast aluminum housing: Excellent heat dissipation, mechanical rigidity, and reduced operational vibration.
Shaft joint coupling: Direct connection ensures concentricity and stability even at max 11,000 rpm.
Digital vs analog control: LHDM900D features touch digital interface with precise RPM readout; LHDM900A offers classic stepless regulator.
Materials & laboratory suitability
Wetted parts: High-grade stainless steel (SS304/SS316L equivalent) – excellent corrosion resistance against acids, alkalis, and solvents.
Viscosity range: Suitable for low, medium, and high viscosity liquids (e.g., creams, pastes, pigments, polymer solutions).
Pilot/Lab scale: Ideal for R&D, QC labs, small-batch production, and scale-up studies.
Feature comparison: analog vs digital experience
| LHDM900A | Stepless speed knob, robust analog electronics, no digital display, ideal for traditional labs and budget-friendly workflows. |
| LHDM900D | Digital touch controller, real-time rpm display, enhanced repeatability, user-friendly data monitoring and parameter memory. |
