Resim

Multistage, vertical shaft pumps used in DM type boosters.
DM serie boosters can be produced with one, teo, three or four pumps depending on the depth for which they will be used.
Level floaters or the boosters set prevent the pump from functioning without water.

In booster pumps bearings are used to compensate for trust. In additioj, there is a sliding bearing underneath made of sintered bronze.
A mechanical seal prevents water leakage at the shaft.
