The main parameters for the selection of a Hawk pump are the flow rate, the pressure, the rotation speed and the absorbed power. 
The flow rate, expressed in litres per minute, is directly proportional to the rotation speed. 
The rotation speed is expressed in revolutions per minute. 
The pressure is expressed in bar and it is the max. pressure admissible from the pump. 
The absorbed power is expressed in kW and it identifies the absorption required to achieve the max. flow rate and pressure 
performances specified. 
If the pump is coupled with an electric motor, the power of the selected motor must be greater than that specified in the catalogue. 
If the pump is coupled with a combustion motor, the power of the selected motor shall be at least 30% greater than that specified in 
the catalogue. 
The absorbed power of the pump, expressed in kW, is calculated with the following formula: 

Power = Flow rate (l/min) x Pressure (bar) / 520. 

 

Hawk pumps must not be used with other materials/fluids and other motor coupling devices from those 
specified hereto. 
If you have doubts, contact the Manufacturer. 

Before  selecting  and/or  using  a  LEUCO  product,  the  buyer  should  carefully  analyse  all  the  aspects 
concerning its application and should examine in depth the information provided in the technical and 
commercial brochures issued by LEUCO S.p.A. 
The products and this document may be subjected to modifications by LEUCO at any time and without 
prior notice.
