UNILIFT AP50B.50.11.3V Submersible Pump

The Unilift AP and Unilift AP Basic range of submersible drainage pumps are designed for both temporary or portable installations as well as free-standing and permanent installations. These single-stage pumps are primarily made from stainless steel. All models are available in both single-phase and three-phase versions, as well as versions for 50 or 60 Hz power supply frequencies. The number included in the type designation (e.g., AP12) indicates the maximum particle size the pump can handle. All pumps in the Unilift AP and AP Basic ranges come with a plug for connection to the electrical network. The single-stage Unilift AP range includes models with a semi-open impeller (AP12) or a Vortex impeller (AP35 and AP50). All pumps in the Unilift AP range feature a stainless steel sleeve used for cooling purposes during operation. The grid located at the bottom prevents particles larger than the design size from entering the pump interior. The grid is secured with clamps to the pump housing. They can be supplied with or without a float switch and can operate in automatic or manual mode. The letter -A- included in the type designation of some pumps indicates that they come with a float switch. The three-phase versions have an additional start-up box connected to the float switch. The Unilift AP Basic range consists of single-stage pumps (AP35B and AP50B) with a vortex impeller. All pumps in the Unilift AP Basic range are made of stainless steel, with a composite support plate.
