The Ebara pump is a double suction single stage vertical suspended pump that is driven by a submersible motor. Consisting of twenty four 5.2 m column pipes that are joined together, the pump is 130 m long. It is the longest pump and has the highest output of Ebara’s large submersible motor pumps.

The pump’s high suction performance is made possible by the impeller’s double-suction, single-stage structure. It also features a reduced load on the thrust bearing, by balancing the hydro thrust force.

Las Vegas’s water is supplied from the lake at the Hoover Dam (Lake Mead). The Hoover Dam’s low water level makes it necessary to use a lifting pump that is at least 100 m to move the water from the dam. Usually, a submersible motor pump of this size comes in a multi-stage structure with multiple impellers. For the Hoover Dam, Ebara has succeeded in achieving the required performance using an impeller with a single-stage structure, which is compatible with a wide range of operations. The single-stage structure is simple, parts-saving and easy to maintain, with reduced lifecycle costs.

Ebara has delivered many large water supply pumps to the Southern Nevada Water Authority, including six surface pumps in a vertical, mixed-flow, multi-stage structure in 2007 to supply Las Vegas with water for daily use from the lake.
