LFE Series 54 Peristaltic Pump


LFE's Series 54 peristaltic pump was designed for use in diverse process analytical applications. It is based on the well proven, highly reliable SR25 pump by Gardner Denver Thomas.

The special design of the pump and the implemented Novoprene tubing guarantee a long service life through high mechanical and chemical resistance.


The microprocessor controlled stepper motor allows a very high degree of flexibility as well as operational stability. The Series 54 pump was designed for continuous as well as discontinuous operation. Various digital inputs allow remote control of speed and direction.
