Laboratory drains carry an unpredictable trickle of whatever gets rinsed down: dilute acids and bases, solvent traces, spent reagents, plus gloves, wipes and pipette tips. None of it is high-volume, but it’s chemically hostile enough to pit a cast-iron pump and leave you with a corroded unit in a sensitive building.
The 50GNWQ15-10-1.5S suits that duty: precision-cast SS304 for chemical resistance, 15 m³/h at 10 m head on 1.5 kW through a 50 mm outlet. The stainless wetted path takes the mild reagent mix, and the 48 HRC alloy cutter clears the gloves and lab consumables that would otherwise block a small line.
One thing to confirm with us up front: the exact chemistry. SS304 covers a wide range, but concentrated acids or specific solvents may point to a higher grade — tell us what goes down the drain and we’ll make sure the pump matches. sales@haquanpump.com
