50PNI2 Automatic Drainage Pumps

The 50PNI2 series are light and compact, automatic pumps with energy efficient motors and integral anti-airlock valves. They feature a dual control float-switch which enables manual and automatic operation. This switch is also adjustable to enable individual setting of on and off levels. The floats are bell shaped and small, which make these pumps suited to applications where a sump is narrow, that require precise level control or where a traditional pendant type float’s operation could be fouled. Liquid paraffin is used for the lubrication oil, which enables use in food processing and aquaculture.

An auto-coupling set is available as an optional extra to allow the fitting of guide rails on each model. They are not recommended for ponds or water features.
