ASI Check Valves
are a High Performance
Upgrade for Your Waters Pump
Replacement Check Valves
Self-priming With the
ASI valve,
priming is easy. Open the pump outlet and turn on the pump. Your pump
will prime itself, even if the head and intake lines are completely
dry. You won't need to use a syringe or draw-off valve to prime your
pump.
Rugged Construction The valve will
not crush, crack, or leak due to high pressure. We designed the
ASI cartridge
so that loads are transmitted through the valve casing rather than the
seat, as in conventional designs.
Convenient and Economical Cartridge Design
When it's time for routine maintenance, you only need to replace the
cartridge, not the entire assembly. The
ASI cartridge
costs no more than most conventional valve rebuild kits, and you won't
spend time chasing ruby balls all over the lab bench.
Pre-tested Every
ASI valve
is tested prior to shipping to ensure it passes a stringent set of performance
specifications.

ASI check valves.
Replacement Piston Seals and Pistons
ASI pump seals and pistons have been developed to
reduce pump downtime. Our UHMW-PE piston seal material is compounded
with other proprietary polymers to provide lower friction and better
solvent resistance than pure UHMW-PE. It generally provides much longer
service life than Teflon and generates less wear material, and we recommend
it for most applications. Our Teflon piston seal has a proprietary additive
to increase resistance to cold flow, and improve wear characteristics.
Teflon is inert to any HPLC mobile phase.
