KSB Pumps Ltd. India won a substantial order for the supply of six boiler feed pumps to be installed in the new, ultra-modern fossil-fuelled power station located in Tanda in the Indian state of Uttar Pradesh.India’s national power utility is currently building two new power plant units there, each with a capacity of 600 MW. The pumps are designed for a pressure of 500 bar. An electric motor and a turbine with power ratings of 11 MW and 17 MW respectively will serve to drive the pumps.

By September 2014, KSB, Germany, will supply eight boiler feed pumps for the new power station in Babelan, Indonesia. The 270 MW oil-fired power station is being built by a Finnish corporate group approximately 20 kilometres east of Jakarta. The order is for the supply of eight boiler feed pumps of which six will be driven by fixed speed 6,000 V electric motors with a 2,260 kW drive rating. To adjust the speed to the varying pump output required, the pump sets have been designed with a turbo coupling between pump and motor. The flow rate of each unit will be around 270 m³/h. The designed head is approximately 1,960 metres and the temperature of the fluid handled 160 °C. The impellers of the 11-stage pumps are made of stainless steel. The total weight of each unit consisting of a pump, coupling and motor is in the region of 25 tonnes.
By September 2014, KSB Aktiengesellschaft, Frankenthal, Germany, will deliver the pumps to be installed in the new combined cycle power station (460 MW) in Wloclawek, 140 kilometres to the northwest of the Polish capital of Warsaw. The order is for the supply of two boiler feed pumps, each driven by a 3,350 kW electric motor.
KSB, Germany, is scheduled to supply a new, state-of-the-art coal-fired power plant located south-east of Pune in the West Indian state of Maharashtra with 16 pumps by November 2014. India’s national energy authority is building the supercritical power plant comprising two 660-megawatt units in Solapur.
By September 2012, KSB will supply boiler feed pumps for the newly built units A and B of the Dutch coal-fired power station at Eemshaven. On the Ems estuary, some 30 kilometres to the north-west of Emden, a German energy supply utility is building an ultra-modern power plant consisting of several 800 MW units which will generate electricity for the Dutch market. The order with a value of several million euros is for two units, each consisting of a turbine-driven main boiler feed pump, a geared booster pump, a minimum flow system and sound insulating hoods.
The SSV, a special automatic recirculation valve, automatically protects centrifugal pumps – especially boiler feed water pumps – against wear and damage, as can occur if the pump runs dry or during low-load operation. Typical damages are for example a temperature increase, which can lead to partial evaporation of the medium, or recirculation in the impeller. It can also lead to flow separation and cavitation in the pump. Similarly, increased vibration and mechanical stresses occur in the pump and cause damage. The SSV bypass control valve opens as soon as the process flow demand falls to the same level as the minimum flow required by the pump. In this way, the specified minimum continuous flow required by the pump is maintained, even if there is zero process flow demand.
