Largest Vertical Submerged

Screw Pumps Successfully

Tested At Delaval Turbine

Performance tests were recently completed at Delaval Turbine Inc., on the largest ver- tically submerged screw pump systems ever built. Designed by engineers at the IMO

Pump Division of Delaval and built at De- laval's Trenton, N.J., plant, the three units are each over 40 feet (12.2 meters) in length and are to be shipped to a Gulf Coast loca- tion for installation on an ocean barge for unloading and stripping service.

Fifty-foot Delaval GTS vertical pump system on the manufacturing floor at IMO Pump Division.

Each of the pumping systems comprises a right-angle drive, ratio 1.2:1, mounting bracket and discharge flange, discharge pipe, stainless steel three-piece drive shaft and

GTS™ geared twin-screw pump with inde- pendent seal balance and lube systems. The pump is driven by a 1,000-hp diesel engine through a 4:1 control fluid coupling to supply a capacity of 5,500 U.S. gallons per minute (approximately 7,860 barrels per hour) (1,250 cubic meters/hour). The pump is rated for speeds up to 1,000 rpm, and a maximum dis- charge pressure of 165 pounds per square inch (1,100 kPa) for liquids ranging from seawater up to crude at 8,000 SSU (190 est).

The unloading systems feature the use of external timing gears and bearings which are isolated from all pumpage. A unique pres- sure balancing and lubricating system serves to lubricate and cools the external gears and bearings, as well as to control differential pressure across the mechanical seals. The working fluid therefore cannot contaminate the lube oil.

Delaval Turbine Inc., a Transamerica

Company, has 15 operating divisions at 18 manufacturing locations worldwide. The com- pany makes a line of industrial products, in- cluding compressors, condensers, connectors, controls, diesel engines, fasteners, filters, forgings, gearing, pumps, sensors, turbines and valves.
