Modular System
KNF pumps are underpinned by a modular concept. Each pump type consists of three main components: pump head, compressor housing and motor. The materials used in the pump head can be substituted to provide greater chemical resistance. Multiple motor options or inter-head connections are available depending on the customer’s requirements. Starting with a series product, any pump can be modified to provide an individual customized solution, which is then referred to as a project pump.
