NP Series agitators are designed for homogenization, dissolution and solid suspension in atmospheric vessels from 1 m³ to 2000 m³ handling low to medium viscosity fluids. Available in two models: NP-M (Medium Duty) and NP-H (Heavy Duty). With motor power up to 132 kW, shaft lengths up to 15 meters and 7 different impeller types, they reliably serve a wide range of industries from water treatment to mining, food to chemicals.
The NP Series consists of top entry industrial agitators manufactured by Mechanimix. They are used for homogenization, dissolution and solid suspension in atmospheric vessels with capacities from 1 to 2000 m³. Offering motor power up to 132 kW, impeller diameters from 300 to 8000 mm and shaft lengths up to 15 meters, the series is produced in two models: NP-M (medium duty) and NP-H (heavy duty). It is widely preferred in chemical, food, pharmaceutical, water treatment, mining and biofuel industries.
Motor, gearbox and shaft configuration can be easily modified to suit process requirements; maintenance performed with a single removal operation
High surface finish preventing dead zones, food-grade gear oil and CIP-compatible custom TH flange to prevent in-tank leakage
Impeller blade angle can be field-adjusted via bolted hub connection; flow direction and intensity optimized without replacing the impeller or drive
Every unit is sized using computational fluid dynamics simulation tailored to your actual tank geometry; minimum dead zones, maximum mixing efficiency
ATEX-compliant explosion-proof design for hazardous environments; full compliance with international standards through IEC/NEMA motor options
Energy-efficient impeller selection, long-life bearing design and easily accessible service points reduce total cost of ownership
Prevents settling in flocculation, denitrification and anaerobic digestion; NP series flash mixers ensure continuous process reliability
CIP-compatible hygienic design for sugar syrup, flavor blending and fruit puree suspension; precise mixing for Newtonian and non-Newtonian fluids
Corrosion-resistant material options prevent settling in slurry mixing and chemical reaction processes, offering extended service life
Heavy-duty shaft and gear unit handling abrasive slurries for reliable operation in conditioning, settling and reagent preparation
Maintains homogeneity of viscous suspensions; prevents filler and pigment settling to improve product quality
Energy-efficient mixing in biodiesel and biogas production; versatile impeller options for different feedstock types
