pumping performance is generally chosen with a margin of about 10-20%. Pumps are often driven by induction motors and run at constant speed based on the power frequency (50/60 Hz). Since the operating performance is adjusted by valves, etc., the excess performance is wasted by valves, etc., and the current condition is that the pump is operated under excessive conditions. By adjusting the rotational speed with the inverter, the pump can be adjusted to the required performance, which makes it easy for anyone to save energy.
Previously, only a few pumps with small output power would be equipped with an inverter at a separate cost. That's why we can expect a significant reduction in power consumption in Japan as a whole by switching our pump to a PM motor with built-in inverter.

Contributing to Reducing Electricity Consumption in Japan
EBARA's annual production of general-purpose pumps is more than about 1.3 million units worldwide. The energy-saving effect per unit may be small, but if we increase the energy-saving effect to the whole factory, the whole region, the whole of Japan, and the world, the energy-saving effect will be very large. In the future, we will further expand our lineup so that more customers can use it comfortably. As a change manufacturer in the industry, we will further accelerate our efforts toward carbon neutrality as a major contributor to reducing power consumption in Japan.
