More About this Item

These pump heads accept the six L/S® precision tubing sizes. For stacking multiple heads (up to the specified limits of your drive) order two- three- or four-channel hardware separately under "Accessories". When two Easy-Load® II pump heads are stacked rollers are offset by 45°--combine the outlets from two stacked heads for a 95% reduction in flow pulsation.

This pump head requires an L/S drive equipped with open-head sensor functionality or the use of the 77097-00 open-head sensor retrofit controller.
