Invertek Drives Optidrive Eco Pump Variable Speed Drive

Drive built for pumping and water applications

The Invertek Drives Optidrive Eco Pump is a variable frequency drive for centrifugal pumps in water supply, pressure boosting, irrigation, wastewater and process systems. It shares the hardware of the Eco family, so it covers 0.75 to 250 kW (1 to 400 HP) on 200 to 600 V supplies, but its software is tuned for pumps. A built-in PLC function, multi-pump control without an external controller, pump prime with burst-pipe detection, blockage detection and cleaning, and operating curve detection are all described in the Eco Pump brochure.

Technical specifications

Pump control functions

Multi-pump control lets one drive manage a small group of pumps, staging them on and off to match demand, without a separate controller. Pump prime and burst-pipe detection monitor the start of the pumping cycle, so the drive can recognise when a pipe has failed to fill. Blockage detection identifies a rise in load that suggests a blocked impeller, and the brochure describes a cleaning function for the same condition. Operating curve detection compares the actual power against an expected pump curve to detect problems like dry running or restricted flow.

Energy savings and installation

Matching pump speed to demand rather than throttling with a valve cuts energy use and mechanical stress on pipes and seals. The drive includes an internal EMC filter and a low-harmonic design to EN 61000-3-12, which helps on supplies shared with other equipment. IP20, IP55, IP66 outdoor and IP66 with disconnect enclosures cover indoor plant rooms as well as pump stations and outdoor installations. The environmental limits follow the Eco user guide, including derating at higher temperature and altitude. When selecting a size, base it on the pump motor full-load current, and consider the cable length to submersible or remote motors, because long cables may need an output filter. The pump hydraulic duty, static head and flow range should be established before the drive control strategy is chosen.
