More About this Item

These pump heads accept the four L/S® high-performance precision tubing sizes. High-performance precision tubing has a thicker wall than precision tubing enabling better pressure generation, greater suction lift, and greater ability to pump viscous fluids.

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.
