Type key
| Example: | MVIE 7003/1-3/16/E/3-2 | | MVIE | Vertical high-pressure multistage centrifugal pump | | 70 | Flow rate in m3/h | | 03 | Number of impellers | | 1 | Number of trimmed impellers;
[only MVIE 70.. and 95..] | | 3 | Material
1 = 1.4301 (AISI 304);
[only MVIE 8.. and smaller]
2 = 1.4404 (AISI 316L)
3= pump housing EN-GJL-250 (cataphoretic coating), hydraulics 1.4301 (AISI 304);
[only MVIE 70.. and 95..] | | 16 | Flange type
16 = flange PN16 (round)
25 = flange PN25 (round)
P = Victaulic coupling [only MVIE 8.. and smaller] | | E | Gasket type
E = EPDM | | 3 | 1 = 1~ (alternating current)
3 = 3~ (three-phase current) | | 2 | Number of poles | | M13 | Only up to MVIE 403, with 1~ (alternating current )
Preset operating mode on delivery
M13 = mode 1 or 3 (manual or remote control)
M2 = mode 2 (pressure regulation mode) |
