East Improvement District & IRZ Consulting Dedicate Largest New Irrigation Pumping Station on the Columbia River in 40 Years.

Hard to believe that it was three years ago that National Pump Company supplied 10 pumps for this Pump Station on the Columbia River near Hermiston, Oregon.

The Station uses 9 Model 24XHC with 2000 HP Motors to pump 11,200 gpm each at 560 ft. TDH, as the primary Pumps and a K20MC-5 1000 Hp as a secondary pump. At the time of dedication, May 7, 2021 Mr. Fred Ziari, president of IRZ Consulting said, “We have designed over 2,000 systems in the last 35 years, but this is the largest and most efficient system we have ever designed, and we are proud of it. During the year-long construction phase, IRZ used more than 100 people, contractors and suppliers.”

National Pump Company supplied the Pumps to Pasco Machine, and acted as the General Contractor supplying and installing the pumps.
