We offer a wide variety of positive-displacement piston pumps and pump kits used in laboratory and industrial instrumentation, including HPLC, UHPLC, Prep LC, and Flash Chromatography systems. Pumps are available in single and dual piston platforms, with flow rates ranging from 1 μL/min to 750 mL/ min, and pressures up to 25,000 psi.
Standard fluid path materials are PEEK, stainless steel and titanium, and there are several control options, including remote RS‑232 & USB interface, LAN port or traditional user keypads, along with binary gradient formation. Available accessories are pulse dampeners, pressure transducers and leak detection. All pumps and pump kits are configurable to meet your specific application need.
Our single-pump systems consist of a controller and pump module. The piston-driven pump module uses a single speed gear train. Nitronic 50 is the standard material for cylinders, pistons, and caps, with Hastelloy and other alloys available for even greater chemical resistance. Standard seals are graphite-impregnated Teflon®, providing long life under harsh operating conditions, with optional seals available for special applications. Continuous-flow systems couple two pump modules to a single controller, and use an active or passive valve manifold to provide non-stop, continuous feed of almost any fluid.
Valves & Fittings
In addition to high pressure pumps, we offer companion valves and fittings to complete the required fluid path. These components include traditional prime-purge valves, industrial needle valves (rated to 15,000 psi); tubing nut/ferrule (in PEEK, stainless steel and titanium), and other high pressure fittings and filters. Manual & motorized rotary valves will be available soon.
