RP-3R Sample Draw Pump

The RP-3R Sample Draw Pump is a compact, battery operated, motorised sample draw pump that attaches to either the Riken GX-3R or the Riken GX-3R Pro to change the functionality from a diffusion operation to a sample draw operation for use as a confined space entry monitor.

The model RP-3R Sample Draw Pump and the GX-3R or GX-3R Pro gas monitor offers a complete solution for confined space entry.

The RP-3RSample Draw Pump is housed in a rugged plastic case with a quick disconnect fitting for hose attachment. It is provided with a 4″ tapered red rubber nozzle. A hose and probe are available as optional accessories. The probe is equipped with an internal dust filter and clear body for easy viewing. The RP-3R uses one AA battery and will operate for up to 10 hours in normal mode (higher flow mode) with an optional ECO mode (lower-flow mode) that can last up to 16 hours. The pump quickly and firmly snaps onto the GX-3R or GX-3R Pro gas monitor and is easily removed when sampling is complete. No tools are required.

A push button POWER switch is used to activate the RP-3R, and the POWER LED illuminates when the RP-3R is on. If a low flow condition occurs, the FLOW LED flashes and an audible alarm will sound.

The POWER LED flashes if low battery occurs.
