AP35B & AP50B Stainless Steel Series

Because of varying applications, Grundfos have developed 2 versions of the popular AP series. For general drainage applications, the new AP35B and AP50B feature composite base plate and can be installed as a free-standing unit or connected to a unique auto coupling system. The auto coupling system allows the pump to be suspended in the liquid and easily removed for service without draining the tank or entering the pump pit. They can be operated for extended periods provided the pump and motor unit are fully submerged but due to the design of the pump, there will always be some liquid remaining in the sump.


With over 30 years experience in the rough and trying conditions of Australia, Grundfos have earned a solid reputation for building pumps and pumping systems that overcome our often harsh environment. Backed by international export quality assurance certification, Grundfos’ range of specialised domestic pumps is a product you can trust.
