Description
The Pentair Jung Drenox 350/12 Manual 230v (code 555-025, Jung N1031040) is the largest single-phase Drenox stainless steel submersible drainage pump. It has a 0.8 kW motor (1.2 kW absorbed) drawing 5.1 A on 230v single-phase mains and a 1¼” outlet, and passes solids up to 6 mm. Jung Pumpen’s table gives 275 litres per minute at 2 metres of head, 250 l/min at 3 m, 200 l/min at 5 m and 108 l/min at 8 m, with 38 l/min still at 10 m.
This is the Drenox for high lifts and fast emptying: it still moves about 200 l/min at 5 metres. In manual form it pumps down to about 35 mm. The Drenox 350/12 Automatic 230v is the float-switched version, the Drenox 350/12 T Manual 400v is the three-phase version, and the Drenox 250/10 Manual 230v is the next size down.
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.
