Shurflo Soft Pressure Pump LS 4121

The intelligent latest version of our proven pressure pumps has a newly developed quiet-running
motor and an integrated bypass control at the heart of the piece.
It lets the water flow very gently and quietly. The pump remains quiet both when opening and when closing the water tap.
Over 30 years of experience has gone into these membrane pumps. They are unparalled in their ability to pump water evenly, suck themselves dry and to run dry. Their manufacturing and development meet the highest international standards such as ISO 9000, EMC and UL. The motors have high efficiency and very low power consumption.
Multiple testing of each pump produced ensures 100% functionality.
