Silent running motors coupled with self drain wet ends make for energy efficient compact pumps.
All models are fitted with a solid motor base with drilled mounting holes spaced at 100mm this makes them a good pump for mounting to anti vibration feet or pre-drilled mounting plates.
This version is fitted with a pneumatic (air) switch so on/off operation is possible either by air buttons or electronic controls.
