The CEB side channel units are a low noise design of combination pumps. They are ideal for pumping liquids that are stored at their boiling point, have a degree of entrained gas, or very low NPSH conditions. The vertical tank pump has been designed in order to enable retro-fitting into most common tanks. Moreover, the dimensions are such that the unit can be used to replace submersible designs of pumps. Although the pump can be supplied in other lengths, the standard size is between 1.3 and 3.0 m.
