From pressurized reactors to aggressive chemical processes — the HP Series delivers reliable mixing in the Vacuum–150 bar range. With HP-M and HP-H models, it operates in tanks up to 2000 m³ capacity across petrochemical, mining, pharmaceutical and biofuel industries.
The HP Series is a top entry pressurized reactor mixer manufactured by Mechanimix. It provides reliable mixing in tanks up to 2000 m³ capacity across a wide pressure range from vacuum to 150 bar. With motor power up to 200 kW, it is offered in two models — HP-M (Medium Duty) and HP-H (Heavy Duty) — and is preferred in aggressive process environments within the petrochemical, mining, pharmaceutical and biofuel industries.
Reliable operation in the Vacuum–150 bar range; suitable for pressurized reactor and CSTR applications
Precise seal positioning minimizes deflection and vibration, extending mechanical seal life
Fine-tune flow direction and intensity without changing impeller or drive; provides commissioning flexibility
Explosive atmosphere design certified to ATEX/IECEx, suitable for Zone 1 and Zone 2 classifications
Stainless steel, Hastelloy, Duplex/Super Duplex, titanium, rubber and ceramic coatings
Up to 15 m shaft in 3 sections; single, double, dry-running mechanical seal or magnetic coupling options
Reliable mixing under high pressure in hydrodesulfurization (HDS), polymerization, crystallization and gas-liquid-solid reactions
Slurry mixing with corrosion-resistant alloys in HPAL (High Pressure Acid Leaching) and pressure oxidation (POX) processes
Controlled nucleation and homogeneous crystal growth in pressurized crystallization, fermentation and bioprocesses; hygienic design
Contamination-preventing mechanically sealed design in fermentation, carbonation and UHT/sterile processes under pressure
Hydrothermal pretreatment, syngas and CO₂ absorption; high-viscosity biomass mixing in pressurized reactors
Viscous slurry mixing in urea, ammonium phosphate and LDPE processes; polymerization with precise temperature and viscosity control
