According to design modifications pumps KsVA 900-180, KsVA 1000-190, KsVA 2200-100, KsVA 2200-170-1 are of centrifugal, vertical, double casing and multi staged type. They provide stable head at parallel operation of pumps and deficiency of air leak through operative and inoperative pump. Pumps are rated for operation with minimal available positive suction bead in vacuum at inlet at condensate temperature close to saturation temperature. To improve anticavitation characteristics before the first stage impeller it is installed booster impeller.

Pumps  KsVA 1500-240 are centrifugal, horizontal, single stage with double-entry impeller. Designed for feed of condensate to deaerator.

Pump casing is cast with semi-spiral feed and double-volute discharge,horizontally splitted. Pump suction and discharge nozzles located in casing bottom part are directed into different sides perpendicular to pump rotation axis.
