Installation type

The installation type of a pump concerns its placement. In addition to the question of whether the pump should stand on a foundation, for example, operators must also take into account that pumps can be operated from different positions. There are four general types of installation:

  • Horizontal: In this installation, which is most common in many industries, the medium flows sideways into the horizontally aligned pump and is conveyed by it at 90 degrees, i.e. vertically. If a pump with a horizontal shaft axis is used, it usually also has to be installed in horizontal alignment.
  • Vertical: In some sectors - such as water management - a lack of space in particular requires vertical installation. The shaft axis is in vertical alignment, gear and motor are located above the pump. This means that the entire unit takes up less floor space.
  • Immersed: If the pump housing comes into contact with the pumped liquid from the outside, wet installation is required. This type of installation can bring cost advantages, especially since usually no seal is required and the motor is located above the fluid level.
  • Submerged: In particular dirt and/or waste water pumps are immersed into the pumped medium to such an extent that they are completely surrounded by it. Therefore, such waste water pumps do not have to be self-priming. However, the pump must be equipped with a submersible motor that is suitable for this operation.

Immersed and submerged pumps are available in both horizontal and vertical versions.

Types of pump installations: horizontal or vertical - dry, immersed or submerged
