UNILIFT AP12.50.11.1 Submersible Pump

The Unilift AP and Unilift AP Basic ranges of submersible drainage pumps are designed for use in both temporary or portable and permanent installations. These single-stage pumps are primarily made of 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 that can pass through the pump. All pumps in the Unilift AP and AP Basic ranges come with a plug for connection to the mains. The Unilift AP single-stage pump 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. The grid is secured to the pump housing with clamps. They can be supplied with or without a float switch and to operate in either 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 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 support plate made of composite material.
