The original design of the rotary lobe pump goes back to the early 40’s and has since then been further developed and improved. Johnson Pump has long experience in rotary lobe pumps. Market knowledge and appreciation of customer needs have been used to improve the existing rotary lobe pump concept with new features and customer benefits.

Rotary lobe pumps are easy to clean and have gentle product handling characteristics. They contain few cavities, which reduces the risk of bacterial growth and makes them particularly suitable for the transport of sensitive fluids – from glue to whole strawberries.
