Rig floor equipment: Two mud pumps offer permanence or lighter weight ///
Ellis Williams Engineering Co., Inc., based in Magnolia, Texas, has developed and manufactured a pair of 2,200 hp mud pumps for offshore and land rig applications. The E-2200 and EH-2200 pumps represent an evolution in pump design and are constructed to achieve maximum horsepower, while allowing for continuous duty in all drilling operations. The two different designs provide the customer with heavy and continuous-duty pumps.
The E-2200 is a full-size, standard-weight pump with a 15-in. stroke and a piston-rod, load rating of 158,374 lb. This pump has an average bearing life of 125,000 hr and is rated at 110 strokes per minute.
The counterpart design, the EH-2200, gives the customer a lighter weight, smaller footprint and a more portable pump than the full-sized pump. This pump has a 14-in. stroke and is rated at 125 strokes per minute. The bearing life averages 100,000 hr and the piston-rod load is rated at 149,324 lb.
