Construction
KS pumps construction
KS pumps are single stage, rotodynamic, centrifugal, horizontal pumps. In a complete aggregate, a pump is connected to the motor through flexible coupling and located on a common foundation plate. The position of the pump connector pipe can be changed in 45o steps until horizontal, according to requirements. Pump impeller of a closed type with single side inlet is equipped on its back disk with radial vanes so as to decrease both axial force transferred to bearings and pumped liquid pressure on shaft seals. Pump shaft bears on rolling bearings. Coupling-side bearing is fixed in the axial direction.
KSM pumps construction
KSM pumps are rotodynamic, centrifugal, horizontal, single stage monoblock pumps. When in a complete aggregate, pump and motor create a single block. Pump casing is fitted to the motor flange together with joining member. On the motor shaft a pump shaft is mounted together with mechanical sealing to ensure leak-free operation, as well as closed pump impeller with single-side inlet. Pumps with up to 3 kW motors are equipped with a base used for their installation on the aggregate foundation. For motors of more than 4 kW, the pump aggregate is installed on the foundation through motor foot.
