Double-walled pumps are fitted with an external pump housing which allows the internal pump housing to be constructed from extremely wear-resistant material. This also means a smaller part of the wall thickness is needed for mechanical strength and a larger part is available for wear losses.
Â
The outer housing also offers optimal security. In case of fracture of the internal pump housing, the outer housing prevents flooding of the pump room. A special type of outer housing is the LightHouse, which is made from reinforced composites with an innovative automated opening mechanism.
Â
Benefit:
Â
* Efficiency up to *0% (as measured in practice) resulting in lower fuel consumption at unchanged Â
  production
* Reduced and more even wear, resulting in longer lifetime of wear parts
* Better performance as a result of the low net positive
* Suction head required (NPSHR)
* Highly versatile application due to steep flow head ratio curve
* Limited influence of wear on pump performance
