- Single/three-phase motor, IP65, 0.12kW - 4 Poles (other powers available on request)
- PVC/AISI316L shaft, lengths 600, 800, 900, 1100 mm (other lengths available on request)
- PVC/AISI316L propeller, 2 blades, 90 mm diameter (other diameters available on request)
GENERAL CHARACTERISTICS
- Suitable for liquids with very low viscosity, on tanks or basins of medium capacity, for mixing chemical reagents or preparing solutions
- Propeller geometry
- Better mixing
- Lower power requirement
- Suction of the mixed additive from the bottom of the tank with less vibration
- Motor connection
- The shaft is more balanced (reduced vibration
- PVC models are coated with epoxy resin for better chemical resistance and fewer rotating components (reduced wear)
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
