THE PUMP

FIRE PROTECTION CONTRACTOR ISO 9001 COMPANY

To avoid cavitation, make sure that there is aminimum pressure on the suction side of thepump. The maximum suction lift "H" inmeters head can be calculated as follows

H = Pb X 10.2 - NPSH - Hf - Hv - Hs

Pb = Barometric pressure in bar.(Barometric pressure can be set to 1 bar.) In closed systems, Pb indicatesthe system pressure in bar.

NPSH = Net Positive Suction Head in meters head.(To be read from the NPSH curve at the highest flow the pump will be delivering.)

Hf = Friction loss in suction pipe in metershead.(At the highest flow the pump will be delivering).

Hv = Vapor pressure in meters head.(To be read from the vapor pressurescale. “Hv” depends on the liquid temperature "Tm")

Hs = Safety margin = minimum 0.5 metershead.(To be read from the vapor pressurescale.“Hv” depends on the liquid temperature “Tm”)

If the "H" calculated is positive, the pump canoperate at a suction lift of maximum "H"meters head.

If the "H" calculated is negative, an inletpressure of minimum "H" meters head isrequired.

c. Motor

The motor is totally enclosed, fan-cooled, 2-pole with principal dimensions in accordancewith the EN standards

Electrical tolerances according to EN 60034

Motor protection

Single phase motors have a built in thermaloverload switchThree phase motors must be connected to amotor starter in accordance with localregulationsThree phase motors from 3 kW and upwardshave a built-in thermostat (PTC) according toDIN 44 082.

Ambient temperature

Maximum +40˚CIf the ambient temperature exceeds +40˚C orif the motor is located 1000 meters abovesea level, the motor output (P2) must bereduced due to the low density andconsequently low cooling effect of the air. Insuch cases, it may be necessary to use amotor with a higher output.
