CEntrifugal pumps

Centrifugal Pumps are the most common and well-established pumps on the market. They come in many different models and can transfer fluids with high efficiency over a wide range of flows and pressures. Johnson Pump offers several series of centrifugal pumps, many of which comply with ISO, EN and API standards.

Johnson Pump’s Combi system is a modular program of centrifugal pumps with a high degree of interchangeability of parts between the different pump constructions. The modular design makes it possible to construct many design variants and it also provides a large degree of interchangeability of components between various pump types and even between the different pump families. This, together with the wide range of materials available, makes it easy to supply the correct design for each specific application; allowing customers to be served in an optimal way.

SPX Flow Technology supplies you with a full range of Johnson Pump brand documentation depending on need and local regulations; ATEX, Material traceability & certification 2.1, 2.2 and 3.1, QHP tests, Vibration tests and Noise level tests.
