Short-path Molecular Distillation Special Pumps
The gear metering pump for short-path molecular distillation is a high-precision, positive-displacement external gear pump designed to complement short-path (molecular) distillation equipment.
Engineered specifically for operating conditions involving extreme high vacuum, high temperatures, and high-viscosity heat-sensitive materials, it serves as a feed pump and a discharge pump for heavy-component residues.
It features a high-vacuum sealing structure that suppresses gas backflow and prevents vacuum loss. Driven by a servo motor, the pump ensures a linear relationship between flow rate and rotational speed, providing continuous, stable, and precise micro-feeding; this guarantees a uniform liquid film on the wiped-film evaporation surface, thereby enhancing separation stability and product yield.
Key Features of morecular distillation pump
• High vacuum sealing structure, minimal gas leakage, maintain ultrahigh vacuum inside distiller
• High precision volumetric metering, low pulsation, stable micro flow feeding
• Optional heating jacket to keep fluid hot and avoid solidification
• 316L / Hastelloy available for corrosive organic media
• Low shear transfer, protect heat-sensitive materials from thermal decomposition
• PLC compatible, servo controlled for automatic continuous distillation line
Applications
Fish oil, Vitamin E, monoglyceride, plant essential oil, polyether, lactic acid oligomer, resin monomer, bioactive extract. Used for feed dosing and heavy fraction discharge in short path distillation.

FAQ
Q: Can this pump work under ultrahigh vacuum?
A: Yes. It adopts special vacuum mechanical seal to reduce gas backflow, suitable for short-path molecular distillation feeding and heavy residue discharge.
Q: Is jacket heating available?
A: Yes. Jacketed pump body for thermal oil circulation, prevents high viscosity media cooling and blocking.
Q: Can you supply pump head only?
A: Yes. Pump head alone or full set with servo motor, coupling and base are both available.
