The revolutionary, EHEDG Certified, Johnson On-Line Pump, manufactured in 316L stainless steel, the On-Line Pump sets the standard for uptime reliability and CIP performance.
It used to be ...
The only way to access the seals or gearbox was to disconnect the process line and dismantle the complete pump head assembly. This was a labour intensive, time-consuming task for the process engineer and therefore costly in lost production.
The On-Line is a vast leap forward for the rotary lobe pump concept and is the key to greater efficiency and reliability through optimum accessibility. Unique front-loading product seal positioning gives faster maintenance, easier cleaning, and less downtime.
By removing only the front cover, both rotors and product seals can be fully accessed from the front of the pump without disconnecting the process line.
Removing the gearbox cover exposes the "back pull out" shaft cartridges for in-line inspection or complete removal without disconnecting the process line. This operation is further simplified by incorporating a spacer coupling when direct-coupled prime movers are employed.
Every feature on the On-Line range has been specifically designed to make dismantling (whether for inspection, cleaning, or maintenance) quicker, easier, and cheaper.
What's more, the forward-seal position places the seals in direct contact with CIP fluids. Superior seal cleanliness lengthens seal life and minimizes seal flaking (product contamination). And because the seals are located directly behind the rotors, areas of product entrapment are eliminated for superior hygienic performance. In fact, the On-Line has the EHEDG (European Hygienic Equipment Design Group) certificate for cleanliness from the TNO laboratory in the Netherlands.
