TOWER – Pump with transmission belts and pulleys
Special pumps designed and studied for the conveyance of highly abrasive liquids deriving from stone processing (laboratories and sawmills), from the treatment / washing of aggregates, from the recovery of cement water and in the glass and ceramic processing sectors.
Vertical axis with sealed chamber bearings sized in such a way as to allow the lower part of the shaft to work cantilevered without supports immersed in the liquid The bodies are divided into two halves and coated in a special anti-abrasive molded compound (consisting of adjustable from the outside).
The impeller is open type anti-clogging consisting of a steel metal core coated with an anti-abrasive compound. It is possible to apply, on specific request, an extension between the nipple and the lower body in order to increase the maximum immersion height of the pump in order to avoid contact between the liquid to be pumped and the lower bearing (or to maintain the electric motor outside the tank / well).
Coupling to the motor by means of trapezoidal belts, with the possibility of varying the rpm and performance of the pump by adapting the electric motor and the type of pulleys and belts.

NAUTILUS – Submersible Pump
This pump can be completely immersed into the liquid to be transferred.
It can therefore be used in situations with limited spaces, very deep pits and wells, etc.
Alfa submersible pumps are also made of materials such as spheroidal cast iron or super alloys highly resistant to abrasion, according to the different industrial applications.
The pumps bodies can be internally coated with anti-abrasive rubber. Delivery rates range from 100lt/min to about 4,000 lt/min, with heads reaching over 30 mca.

NEPTUNE – Horizontal Monoblock Pump
Pump designed to meet the needs of feeding small filter presses.
The application of an anti-abrasive rubber tube between the pump outlet and the fixed pipework to the filter press is recommended as an anti-vibration device and for easier installation.
Since this type of pump is not self-priming, it must operate under head.
Designed for extremely heavy duty, they are highly reliable and cost-effective thanks to their exceptional robustness.

WALF – Hydrocyclones Pump
Guaranteeing high flow rates and high heads, they are ideal pumps for use in the industrial and tertiary sectors.
They are used in the feeding of hydrocyclones in the treatment and inert washing sector and in all areas where abrasive and/or acidic liquids need to be transferred.
The bodies and impellers can be cast with superalloys of high mechanical abrasion resistance (hardnesses of approx. 800 HB), or coated with special anti-abrasive rubber compounds.

Delta – Double Stage Horizontal Pumps
Studied and designed to feed filter presses; they can be supplied with single or double speed motors, with pump-motor coupling via belts and pulleys or with direct coupling via coaxial coupling.
Depending on the versions, a range of flow rates is available, ranging from 100 lt/min to 10,000 lt/min with indoor pressures up to 16 bar.
The bodies and impellers can be made of super alloys or spheroidal cast iron coated with special anti-abrasive rubber compounds.
The suction inlet is positioned so that the sludge does not come into direct contact with the mechanical seals, the latter made of tungsten carbide, drained with water and protected by a pressurized barrier chamber.
The functionality of the bearings is guaranteed by lubrication in an oil bath.
