Milton Roy announced enhancements to its Solaroy series of solar-powered metering pumps. Run on a 12-V battery charged by a solar panel, the pumps feature an enhanced drive specifically engineered to accommodate target-end load force. New radial bearings reduce frictional losses and increase the performance balance between torque and motor efficiency. The operational run time in batch mode has been increased from 24 hours to 99 hours.
