New Pumps For Indian Power Station

Order won based on past success; plant built by national energy authority

Posted on March 15, 2013

KSB Aktiengesellschaft in Frankenthal, Germany, has secured a contract that includes a 2014 delivery of four large turbine-driven duty pumps, four smaller start-up and stand-by pumps driven by electric motors, and eight booster pumps to a new coal-fired power plant located in Solapur, southeast of  Pune in the West Indian state of Maharashtra.

India's national energy authority is building the supercritical power plant comprising two 660 MW units in Solapur.

The duty pumps' maximum flow rate is 1265 m3/hr. The highest head as per project specifications is around 3675 m, and the operating temperature is 190oC.

The maximum input power of one of the turbine-driven boiler feed pumps ranges at 13.2 MW, depending on the operating point. Each boiler feed pump is supplied with the required inlet pressure via its own booster pump. The total weight of a complete unit of this type is between 40 and 50 tonnes.

One reason that the Frankenthal-based pump manufacturer won this technically demanding and strongly contested order was that it had successfully equipped the Indian power plants Sipat and Barh – operated by the same energy utility – with pumps and valves.
