UNILIFT AP12.50.11.1 submersible pump

The submersible drainage pumps from the Unilift AP and Unilift AP Basic ranges are designed for use in both temporary or portable installations as well as free and permanent ones. These single-stage pumps are primarily made of stainless steel. There are single-phase and three-phase versions of all models, as well as versions for electrical supply frequencies of 50 or 60 Hz. The number included in the type designation (for example, 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 connecting to the electrical network. There are models in the single-stage Unilift AP pump range with a semi-open impeller (AP12) or Vortex impeller (AP35 and AP50). All pumps in the Unilift AP range feature a stainless steel jacket used for cooling purposes during operation. The grille located at the bottom prevents particles larger than the design size from entering the pump. The grille 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 have a float switch. The three-phase versions have an additional starter 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.
