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…

Eldex pumps can move fluids with viscosity measurements up to 500 centipoise (something between SAE 30 oil and glycerin), though at viscosities above 100 centipoise (something like SAE 10), the…

Eldex pumps are designed to operate under ambient temperature conditions. Do not use the pump in an environment that exceeds 35°C. It is possible to pump fluids at elevated temperatures.…

We recommend selecting a pump that typically runs in the upper half of its flow rate range for the best pump efficiency. For the valves to operate effectively, a pressure…

Laboratory and industrial processes often require metering precise amounts of fluids in a controlled and reproducible manner. Optos Series pump models were developed in response to this need. These pumps…

Eldex Optos Series pumps attain precise metering through a positive displacement, reciprocating piston. A stepper motor drives the piston via an eccentric. Advanced software algorithms control motor speed based on…
