Horizontal pumps are a design where the pump head is located adjacent to the motor on a horizontal plane. Connected with or without a coupling, they can be baseplate mounted if long coupled, or with simply a footplate if close coupled.
Vertical sump pumps:
Vertical sump pumps are intended for use in the industrial pumping applications to pump clean or lightly contaminated liquids, fibrous slurries and liquids containing large solids from the deep sumps. The pumping head is suspended into the pumped liquids and the drive motor is dry installed on the top.
Vertical cantilever pumps:
Vertical cantilever pumps are centrifugal pumps designed in a way where the impeller is "cantilevered" from the motor and baseplate (a cantilevered structure is one that is anchored at only one end – think of a diving board at the edge of a swimming pool)
Vertical turbine pumps:
Vertical turbine pumps are centrifugal pumps, also known as the vertical pump, deep well, or line shaft pump. They are built to be fully submerged in water and are designed to move water from underground wells or reservoirs
