Seaweed-clogged intakes will cause marine air conditioning pumps to run dry, burning out the motor of most pumps. These sturdy, stainless steel and bronze pumps have thermal overload protection and can run dry without failing. The pump motor is permanently sealed in nontoxic lubricant for years of reliable running. Can be submerged.
Pumps are not self-priming and must be located below the waterline. Operates on 110V AC. Each pump is UL-listed, ABYC-compliant and USCG-approved. One-year warranty.

Comments about Seawater Circulation Pumps:
My aircon CAL Pump has been leaking oil since 2 years into service and finally, it trips due to overheat after 4years with total loss of oil. Simple solution, open the large allen grub screw infront of pump, pour in Luboil (same SAE 15W40 as for my diesel engine), re-orientate the cable entry to top facing and the pump is back in service. Was leaking oil through cable gland when gland was faced down. Great pump, no need to buy replacement.

Comments about Seawater Circulation Pumps:
I have replaced two MS-580s in two seasons. Each was used to run my 16K BTU Marine Air AC. While they appear rock-solid and are easy to install, both began leaking their dielectric fluid into my bilge half-way through the summer. While the company declares they have a thermal switch to prevent damage if the intake is clogged, it seems they do not shut off until they are already leaking. Unless you plan to only use these pumps a few months out of the year in crystal clear water, I highly recommend looking at another pump.

I invested in the larger pump and the penquins are jumping off the dock to get into the cold boat!

Comments about Seawater Circulation Pumps:
I'm replacing my boat's original pump after ten years of using it heavily. It's very hot in AZ and we are on the boat every weekend, running the AC constantly. Since the last one gave ten years of hard service, I'm buying the same brand and model to replace it.

Comments about Seawater Circulation Pumps:
The Cal pump is very high quality. It's casing is stainless steel and brass. It was easy to install, and has pumped flawlessly since it was installed. It's also very quiet.

Comments about Seawater Circulation Pumps:
This is the second CAL pump I am replacing for my marine AC system. The CAL Pumps are increadibly easy to install. They look and feel like a quality product and run very quiet...so quiet that it is difficult to tell when it stops working. Both stopped working unexpectedly right at the two year mark, when the warranty runs out!
They are a bit pricey to be changing out every other season so I will be providing a review for different brand this next time around.

Comments about Seawater Circulation Pumps:
Pump works well, but leaks lube oil from the housing. The stuff is difficult to clean up and leaves a smelly residue in the bilge. Warranty is not helpful and it cannot be repaired.

Comments about Seawater Circulation Pumps:
I have had two units in my boat and BOTH have leaked lube oil from in between the copper/brass and stainless fittings. The first was replaced under warranty, but now the manufacturer will not replace the second, as the "orginal warranty" has expired. Save yourself the headache of trying to clean up an oily mess and go with another pump. This one is junk.
