Liverani 1-1/2" Stainless Steel Pump with Motor

Notify me when this product is available:

This is a stainless steel, low-speed rotary pump with flexible impeller is particularly suitable for the transfer of delicate, fragile and viscous fluids, also with solid parts in suspension. These pumps are widely used in the oenological field and in food processing.
The flexible impeller vanes deform slightly to pump the liquid inside the pump and move it to the discharge port at a stedy flow rate. This principle combines gentle pumping with a high self-priming action.
Self-priming - automatic priming of the product up to 6 m even from dry start-up.
Reversible operation - the pump can operate in both rotation directions, which permits return of excess liquid without any manual intervention, and also allows easy emptyng of pipes on completion of liquid transfer.
Excellent priming action - even at a low revolutions, which allows the transfer of soft and fragile fluids with viscosities up to 50.000 cp, or with solid particles in suspension, without causing air-locking, avoiding emulsifying or damaging particles.
Smooth steady pumping action of the product without pressure spikes even flow rate ideal for filling, dosing or filtration.
The pump can work in all mounting positions.

Impeller features:
Natural Rubber (NR) - Excellent for water based liquid at room temperature, highest mechanical resistance.
Neoprene (CR) - Good balance between chemical and mechanical resistance.
Nitrile (NBR) - Excellent resistance to oils and fats.
EPDM - Best for hot fluid and CIP cleaning. Excellent for acid and alkaline fluids.
Silicon (VMQ) - Best for high temperature but low mechanical resistance.
