Mondi Utility Sump Pump 1585X for Hydroponic Reservoir Drainage
The Mondi 1585X is the brand's 1/2 HP, 1585 GPH submersible utility pump. A workhorse for moving water out of a flood tray, down a recirculation line, or out of an unexpected indoor flood. The motor runs at 3450 RPM on standard 115V, 60Hz wiring. The cooling system is oil-less and water-cooled. That matters in hydroponic rooms — there is no gear oil that can foul a nutrient reservoir if a seal ever lets go.
Mondi 1585X Gold Series Submersible Utility Pump in a Grow Room Build
The pump ships with an adjustable multi-size discharge fitting. It steps through 1/2", 3/4", 1", and 1-1/4", plus a 1/2" garden-hose adapter. The fitting lands cleanly on industrial tubing or a standard garden hose without an extra trip to the hardware store. The 20 ft grounded cord reaches well past the edge of a typical reservoir or sump pit. Growers typically place the 1585X at the lowest point of the reservoir and run the discharge to a drain or a transfer tank. Two notes worth flagging before install. This model does not include a float switch. The 12.85 lb body sits at 9.3" x 8" x 11", so confirm the sump pit can fit it.
