Calpump Bronze and Stainless Steel Pumps

Calpump's stainless steel and bronze pond pumps are very reliable. Typically used in Koi or goldfish ponds to power filters and waterfalls, they can also be used with mid-size to large fountain nozzles. The S580, S900 and S1200 gph models have a 3/4" MPT intake and a 1/2" MPT outlet that easily accommodates 3/4" flexible tubing. All of these models must have either a screen or foam pre-filter attached to the intake. We highly recommend using the MAN foam filters. These pumps can easily be connected to biological filters, ultraviolet sterilizers, ultraviolet clarifiers and in pond filters.
