Unilift AP Basic pumps are single-stage pumps (AP35B, AP50B) with vortex impeller. All Unilift AP Basic pumps are made of stainless steel, with a composite baseplate. The Unilift AP Basic range is designed for submerged operation, either free-standing on the base plate or installed using an auto coupling. The pump inlet is designed to prevent to large particles from entering the pump. The base plate is clipped on by means of four clips hidden under the composite ring at top of the pump housing. The ring prevents dirt from sticking to the clips. All Unilift AP Basic pumps can be supplied with or without float switch, for automatic or manual operation. Pumps with an ”A” in the type designation are fitted with a float switch. The outlet is positioned at the side of the pump and is R 2.
