15.1 WARNINGS FOR CORRECT OPERATION OF EVMU
AND EVMSU PUMPS (FIG. 1 - FIG. 2)
FIG. 1
a) Adequate immersion;
b) Positive slope;
c) Wide-radius bend
d) Pipework with independent supports;
e) Suction pipe diameter ≥ pump port diameter;
f) Reducing coupling for eccentric pipes.
FIG. 2
a) Insufficient immersion;
b) Negative slope, air pockets created:
c) Tight bend, pressure loss;
d) Pipe diameter < pump port diameter, pressure loss
