Flowserve to Provide New Deep-Well Submersible Pump and Motor to German Geothermal Power Plant

Posted: Monday 12th March 2012

Flowserve Corporation was awarded a contract to provide a new deep-well submersible pump and motor to the Germany-based geothermal power plant, Geothermische Kraftwerksgesellschaft Traunreut.

Developed in conjunction with the German government, this innovative, high-energy submersible motor took approximately four years to commercialize and is designed to help Germany meet its renewable energy goals. The order was booked in September.

With a motor size of 850 kW (1,140 hp) and a flow rate of 130 l/s (2,060 GPM), this highly-engineered, vertical pump and oil-filled motor is designed to be installed at a depth of 600 m (2,000 ft) and used to pump water with temperatures up to 140C (285F). Once the geothermal fluids reach the surface, the steam produced in a secondary circuit will be used to turn the turbines that generate electricity, creating a renewable and environmentally-friendly source of power. The planned geothermal power plant will generate electricity and heat to the district with a capacity of up to 5.5 MW of electrical power and a maximum of 12 MW of thermal energy.

"Flowserve is proud to have been chosen as a partner by the German government to create this innovative, deep-well submersible pump," said Tom Ferguson, president, Flow Solutions Group. "This order helps solidify our position as a leading pump manufacturer with the ability to provide our customers an array of pump solutions for a geothermal power plant."

The binary cycle geothermal plant is expected to come online and deliver heat during the fourth quarter of 2013 and electricity by the end of 2013.
