MX L Lenses

• Motor + gearbox single/three-phase, IP65, 0.12 kW - 4 poles (other powers available on request), reduction ratio 1:7-200 rpm (standard), 1:20-70 rpm (optional)
• PVC/AISI316L shaft, lengths 600, 800, 900, 1100 mm (other lengths available on request)
• PVC/AISI316L propeller, 2, 3, 6 blades (flat or perforated), 90, 150, 220 mm diameter (other diameters available on request)

GENERAL CHARACTERISTICS

• Suitable in the water treatment sector for flocculation and preparation of polyelectrolytes
• Propeller geometry
  • Interchangeable PVC propeller blades
  • Additional blades on the propeller for special applications (sold separately in assembly kits)
  • Possibility of adding a second propeller on the shaft for better agitation with suspended solids (sold separately in assembly kit)
• Motor connection
  • Slow agitator speed changes from 70 rpm (optional) to 200 rpm (standard)
  • Electric motors are fully interchangeable throughout the range (0.12÷0.37 kW)

AGITATOR POSITIONING

G>100 - Fast / G>100 - Lenses
N.B. - In the case of central mounting, 3 anti-rotation 120° blades must be provided for fast agitators and 4 blades for slow agitators

• A - Liquid height
• B - Tank diameter
• C - Distance of the propeller from the bottom
• D - Distance between the 2 propellers
• E - Propeller diameter

• For 0.5<A/B<1.1 - 1 Propeller
  • C=0.5÷2xE
• For 1.1<A/B<1.6 - 2 Propellers
  • D=5÷E (Fast) / D=2÷E (Lenses)
• Choice of propeller diameter depending on the tank
  • E=B÷0.2 (Fast ) / E=B÷0.3 (Lenses )

VERIFICATION OF ENGINE POWER

The agitators are equipped with a suitably dimensioned motor. To calculate the required power, multiply:

• Real P = P Used x liquid density x viscosity coefficient (Real P = power in water)

You must check that the motor power is:

• = Real P + 5% (Fast) / = Real P + 25% (Lenses)

It should be borne in mind that:

• Increasing the speed by 50% requires increasing the power by ∼ 3 times
• Increasing the propeller diameter by 50% increases the power by 7 ∼ times

Example:
950 rpm required with Ø120 propeller and 0.25 kW motor

• A 1 kW motor must be chosen to run at 1400 rpm
• A 1.5 kW motor must be chosen to use a 180 propeller
