Used for decades as a commercial fountain pump, the marine version of this pump is ideal for a wet bilge where moisture and explosive fumes may be a hazard – typically used as a continuous duty marine a/c pump.
Always mount this pump with the volute pointing down or to the side as shown to lubricate and cool the shaft. If the discharge barb is positioned as shown, air is more easily purged.
Like all centrifugal pumps, they are not self-priming and must be mounted below the waterline.
Cal-Marine "MS" series:
These quality direct drive, centrifugal marine pumps feature a rugged bronze/stainless casing, an easily replaced nylon impeller mounted on a 304 stainless shaft with a hard chrome plate and a double lip viton seal, all inside a heavy-duty nylon volute.
