GROCO 17 GPM Bronze Centrifugal Baitwell Pump

The GROCO CP-20 centrifugal pump is built for baitwell circulation and other onboard jobs that need strong water movement without unusually high discharge pressure. Its 17 GPM output gives a livewell or bait tank enough turnover for many common installations while retaining the simple operation of a continuous-duty centrifugal design. The inlet and discharge are threaded for a compact plumbing connection, and a garden-hose adapter is included for applications that benefit from that convenient outlet option. GROCO also uses an ignition-protected motor, an important feature when electrical equipment is installed in appropriate gasoline-powered vessel spaces.

The CP-20 combines a bronze pump body with a 316 stainless-steel shaft and a continuous-duty mechanical shaft seal. Those components are selected for repeated marine service, where corrosion resistance and dependable shaft support matter. GROCO's related CP-30 uses the same basic pump concept but adds externally replaceable motor brushes for installations where that service feature is desired. The pump is intended for relatively high flow at modest pressure, so it is better suited to circulation and transfer work than to a pressure-demand water system.

Mount the CP-20 where the pump can receive a dependable flooded or properly supplied intake and where the motor stays accessible for inspection. Size the wiring and circuit protection for the pump's electrical requirements, and route plumbing so the inlet is not starved by unnecessary restrictions. After installation, confirm steady flow and check the shaft-seal area and threaded connections for leakage during an extended test run.
