Industry Leader

Regardless of the energy type, all power stations - including coal fired, nuclear, gas turbine and even hydroelectric - require metering pumps of some fashion in their operation. With an around the clock operation and close to zero downtime, these energy plants demand a reliable and accurate dosing and metering pump to keep up with the modern world's requirement for 24/365 power needs. While these pumps are often forgotten in the vast infrastructure of a power station, they are central to the heart of the operation, and often the cause for plant shutdowns when they fail.

Throughout our history, Neptune™ has built a reputation as a leading supplier of hydraulic diaphragm metering pumps for use in conjunction with boilers and cooling towers in power plants. From unique capabilities like the Variable Oil By-pass™ stroke adjustment for better valve performance, to the EZE-CLEAN™ valves with cartridges that can be removed for cleaning without disturbing the pump's piping, and other pump technologies with the ability to operate at high pressures, Neptune has the metering pump capabilities to handle a variety of energy application needs.
