Reproducible metering Precise metering at high pressure is attained by a positive displacement, reciprocating piston assembly. The piston is driven by a constant speed motor via a specially contoured cam. The cam profile is designed so the piston rapidly intakes and delivers a smooth, constant volume of fluid to the end of the piston stroke. Thus, motor efficiency is maximized and pulsation minimized.

Micrometer control Reproducible metering is attained by precise control of the piston's stroke length and rapid response check valves. The piston's stroke length is fixed by a precision micrometer which is simple to use and assures reproducible metering. The inlet and outlet check valves regulate flow direction. The piston assembly is uniquely designed to permit an even application of the force driving the piston- a detail which helps to ensure exact, reliable liquid transfer and extended seal life.

Corrosion resistance The materials in the liquid end of Eldex pumps are carefully chosen for corrosion resistance. The piston is sapphire, and the inlet and outlet valves incorporate sapphire seats and ruby balls. The standard piston seal material is an ultra-high molecular weight polyethylene with excellent chemical compatibility characteristics.

Reliable Design The compact pump housing, unique piston assembly and many other features demonstrate dedication to building precision metering pumps made to last.
