Description
The Pentair Jung Drenox 80/7 Manual 230v (code 555-003, Jung N1031090) is the smallest Drenox stainless steel submersible drainage pump. It has a 0.2 kW motor (0.3 kW absorbed) drawing 1.3 A on 230v single-phase mains and a 1¼” outlet, and once primed it pumps down to just 3 mm of water. Jung Pumpen’s table gives 57 litres per minute at 2 metres of head, 43 l/min at 3 m and 17 l/min at 5 m, with the curve ending at 6 m.
That 3 mm drawdown makes it the Drenox to choose for a flooded floor, a shallow pit or the last of a tank. As a manual pump it runs whenever the power is on, so stay with it or switch it from a separate float switch. The Drenox 80/7 Automatic 230v is the float-switched version, and the Drenox 160/8 Manual 230v is the next size up, around 100 l/min at 3 m.
Like every Drenox, it is made entirely from AISI 304 stainless steel: pump housing, impeller and motor casing. The stainless steel shaft has ceramic inserts where the seal wears, the double seal is NBR rubber with a sand guard V-ring running in an oil chamber, and the ball bearings are self-lubricating. A heat exchange chamber cools the motor, so the pump can run for long periods without being fully submerged. The motor is IP68 with Class F insulation and runs at 2850 rpm. The pump is rated for immersion to 7 metres and water up to 40°C, and comes with 10 metres of H07RN-F cable and an elbow hose fitting for 32 mm hose on the 1¼” outlet.
The single-phase motor has a thermal overload built into the winding that resets automatically.

Flow is converted from Jung Pumpen’s published performance tables for the 230v and 400v pumps. Jung does not publish separate figures for the 110v 80/7. Automatic versions stop at the float switch-off level shown. See the Pentair Jung Drenox drainage pump range page for help choosing and answers to common questions.
