Multi-stage centrifugal pump

摘要

The stepped housing (2) is connected to the intermediate extraction line (3) through the breach (8) of the housing canister (1) by way of a flexible element (4). This is bolted onto the stepped housing (2) with the aid of a flange (6). Its other end is fixed to an intermediate connection (12), which is detachably connected to the housing canister (1). The new design allows the flexible element (4) compensating for relative movements to withstand relatively high outlet pressures and facilitates easy assembly and dismantling for a minimum diameter of the breech (8) in the housing canister (1). <IMAGE>
