Refill rate refers to the speed of the piston retraction during the pump refill stroke.  Full Out refers to a maximum speed refill designed to minimize pulsation.  With DI water…

Eldex pumps do not work well with slurries due to the pump's check valve design, where particulates can interfere with the ball and seat sealing, leading to an inaccurate flow…

The accuracy requirement is different than reproducibility (precision). The accuracy of our pumps (measured flow rate vs. pump set point flow rate) is affected by check valve function, piston seal…

Eldex pumps are designed for constant flow rates, not constant pressure.  Pressure is a byproduct of the flow, i.e., higher flow with the same outlet restriction results in higher pressure.…

The Optos Plus models include an integrated pulse damper for smooth flow, pressure monitoring, and the ability to set high and low-pressure limits.

Eldex Optos and HP Series pumps are reciprocating piston-style pumps, meaning the pump fluid chamber is static. Therefore, at a constant stroke, the same amount of fluid is delivered to…
