Collecting tank for grey wastewater The 30-litre tank is designed to be equipped with a Unilift KP pump to get a compact lifting station for installation below sewer level. The tank has a vent with charcoal filter and an overflow protection. The lifting station is suitable for pumping grey wastewater with a maximum particle size of 10 mm from washing machines, showers, washbasins, sinks, etc. The lifting station must not pump wastewater containing discharge from toilets. The tank has three side inlets, DN 40, and one top inlet, DN 40 or 50. The outlet is DN 40. The pipe kit delivered with the tank includes a non-return flap valve and lever arm guide, which is to be clipped onto the pump for reliable start and stop. The pump must be ordered separately. You can choose the pump from the UNILIFT KP range. The pump must have a float switch for automatic start and stop, version A1.
