PUMP PERFORMANCE CURVE
- H = f(Q) – lift head acc. to rate flow,
- P = f(Q) – power input acc. to rate flow,
- η = f(Q) – efficiency acc. to rate of flow,
- HS = f(Q) – allowable suction head acc. to rate of flow,
- NPSH3 = f(Q) – net positive suction head and rate of flow.
MAIN DIMENSIONS OF PUMP
CONNECTION SIZES OF PUMP
The flanges are normally made in accordance with the standard PN-EN 1092-1 or PN-EN 1092-2.
MAIN DIMENSIONS OF PUMP UNIT
It is possible to produce pumps with parameters different than those presented in the tables and on the graphs per agreement with the manufacturer.
