CALCULATION DATA
Calculation example for pump CK 1229 installed 500 m above see level
The calculation show that the pump can suck from 0,72 m (2,34 ft) height. If Hz would be
positive, the pump should bee feed under pressure.
Pipe length (drawing) 1+1+2= 4,00 m
3,3+6,6+3,3= 13,20 ft
Equivalent length of 2X1,13= 2,26 m
