Estuary Pump

CERN-OHL-S-2.0

Splash-rated peristaltic pump for shallow estuary deployments.

oceanography hardware URI Graduate School of Oceanography updated 2026-07-09

What it is

A field-portable variant of the WHOI Pump v1, repackaged for shallow
estuary deployments where the pressure housing is overkill. Same pump
head, lighter electronics, surface-tethered.

What changed from the WHOI Pump

  • Pressure housing replaced with a splash-rated enclosure.
  • Battery moved topside; tether carries power and serial.
  • Controller swapped to a smaller MCU. Firmware is a near-rewrite.

The mechanical pump head, the flow profile, and the seal stack are the
same as the WHOI v1.

Submitter's self-rating

5/10 (self-reported by the submitter)

One season of estuary deployments in Narragansett Bay. Splash enclosure leaked on a single deployment; the surface tether is the weak link. Mechanical pump head is unchanged from the WHOI v1 and is solid.
