Sixth Infrastructure Maintenance Grand Prize in the Ministry of Agriculture, Forestry and Fisheries awarded "Excellence Award" for "Horizontal Axis Pump Technology for Dry Start (Low Torque Start)"


Award ceremony Award ceremony

The newly developed dry start compatible horizontal shaft pump technology (hereinafter referred to as "this technology") developed by EBARA Corporation (hereinafter referred to as "EBARA") has won the 6th Infrastructure Maintenance Award. *1 It won the Excellence Award in the Ministry of Agriculture, Forestry and Fisheries category at the This is the second time that the company has won an award at the Infrastructure Maintenance Awards, following the first time that the "Easy Inspection Pump" won the "Minister of Land, Infrastructure, Transport and Tourism Award" at the awards.

1. Background

The facilities that form the foundation of our lives and industrial activities were developed intensively during the period of high economic growth. Many facilities and equipment, including drainage pumping stations, were built more than 40 years ago, making it difficult for them to function properly, and there is a need to strategically maintain and update this infrastructure.

2. Overview

This technology suppresses the temporary increase in motor starting current that occurs when starting electric motor-driven suction-type horizontal shaft pumps (Diameter 350 to 2,000 mm) used for agricultural pumping and drainage in a non-full state (dry start). This reduces the flicker phenomenon ※2 This not only reduces the amount of water that can be pumped, but also enables a stable transition from full to drain operation while the pump impeller is running dry. With this technology, simply attaching an inexpensive dry start device to the pump body eliminates the need for expensive electrical equipment to suppress starting current, making it possible to significantly reduce the maintenance costs of existing pump equipment.
