Application:
The Multistage mining dewatering pump is best applied in applications like these:
• Reverse Osmosis
• Boiler Feed
• Shower
• Spray
• Cogeneration
• Pressure Boosting
• High Pressure Cleaning
• Snow making
• Condensate
• Mine dewatering
Nomenclature:
DG45-80x6
DG means multistage centrifugal boiler feed pump
45 means the design point of capacity of the pump is 45 m3/h
80 means the design point of single-stage head is 80m
6 means the pump stage is 6 which also means it has 6 impellers.
Performance table:
DG45-80 series of centrifugal multistage pump can be 6~12 stages options with same flow capacities range(36 m3/h~62 m3/h) but different heads requirements(from 409m to 1003m)
capacity (m3/h) | Head (m) | Speed (r/min) | Efficiency (%) | Power (kw) | Motor | NPSHr (m) | Impeller Dia. (mm) | weight (kg) | Shaft Power (kw) |
| 36 | 502 | 2950 | 50 | 160 | Y315L1-2 | 3.9 | 260 | 113 | 98.4 |
| 45 | 480 | 55 | 4.0 | 107 | |||||
| 62 | 409 | 56 | 5.5 | 123.3 |
