Enviroflex L25 Series Peristaltic Hose Pumps

Enviroflex L25 Series Peristaltic Hose PumpsWith our Enviroflex L Series pump you get all the benefits of other peristaltic pumps, with the two key additional benefits of a much slower speed for a given flowrate; and rotating rollers for soft hose compression. These two features greatly increase hose life & reduce power consumption.

The L Series pump displaces typically twice the flowrate of our competitors pump and we achieve this by making our pump larger*. In our design the rollers effective contact with the hose is maximised, producing an increased flow perrevolution. This means we can run our pump at about half our competitors speed to produce the same flowrate and hence double the hose life*.

Our pump uses soft action rotating rollers to compress the hose instead of hard fixed shoes. The advantage of our rollers is that they gently rotate as they compress the hose, losing very little power from surface friction. Fixed shoes
by stark comparison apply a large contact area, that drags on the hose surface, creating a high level of wear, friction and hence significant power loss.

The L25’s design features will provide you with typically TWICE the expected hose life and significant power savings when compared to other peristaltic pumps*.
