Seaflo 33 Series Boat and RV Pump

Ease Of Use

This pump features industry standard fittings, wiring, and mounting base to directly replace similar competing pumps.

Beats The Competition

The three-chamber high volume design is driven by a heavy-duty motor which produces flow rates of 3.3 GPM and 45 PSI. It is capable of self-priming up to 6 vertical feet and can run dry, making it a clear cost to performance leader.

Diaphragm Pumps

Ranging from 1 to 5 GPM capacity, SEAFLO automatic demand water pumps have a built-in pressure switch which automatically starts and stops when the faucet is opened and closed. They're easy to install, service and winterize.

Bilge Pumps

The SEAFLO Submersible non-automatic bilge pump line handles bilge water evacuation and is controlled by a panel or float switch. They all include Anti-Airlock protection and moisture tight seals with marine-grade blocked wiring. The removable strainer base fits industry standard mounting conventions, so you’ll have no problem swapping to SEAFLO.

Washdown Pumps

SEAFLO’s washdown kits are the best choice for cleaning boats, fish boxes, anchor wells, dinghies, and other similar applications. Ranging from 3 to 5 GPM capacity and with an on-demand switch, the pump automatically turns on when you squeeze the spray gun handle.

Seaflo Dry Bilge System

The SEAFLO Dry Bilge System is the most economical and reliable way to keep your bilge clean and completely dry. The SEAFLO Dry Bilge System removes all still water from the lowest part of your bilge, or other water-containing compartments. The system is self-priming up to 25 feet, so it can be mounted remotely from the suction foot. The system is activated either by the easy-to-use programmable timer, or manually by a toggle switch.

User questions & answers

Question:	is it self-priming
Answer:	Probably an air leak where hose or strainer is attached
Question:	Does this come with the inline filter
Answer:	ALWAYS install your pump prior to the water heater friend. No, this is NOT a hot water pump.
Question:	Can this be set up to be powered by your standard wall outlet at home
Answer:	Normally you would have kept the paper work or purchased the warranty from Amazon. However I have never seen my pump cause Amazon has never sent it.
Question:	Is this pump variable speed
Answer:	I don’t see any reason it wouldn’t. Works very well with fresh water tank.
Question:	Pump worked great pulled out hose from drain to clean and now pump runs but no water. Priming issue
Answer:	This pump has a 4 year warranty that is honored by the seller you purchase from.
Question:	will this pump hot water for a shower? approx. 100 degrees
Answer:	Hello,Yes that is correct. This is an on demand pump, so when you release the pressure, by turning on a faucet for instance, it will activate. Once you turn off the faucet and the pressure builds to 40 PSI it will deactivate the pump. Please let us know if you have any further questions, have a great day!Thanks,Paramount Direct
Question:	How do I make a warranty claim? I’ve had the pump for less than a year and it is now leaking water out of it
Answer:	You will definitely have the pressure you are looking for but I do not know if the duration will be there for spraying. You may want to contact the manufacturer to determine if this pump is adequate for your needs or take advantage of a pump they recommend for your specific activities. Hope this helps but I use my pump simply to maintain pressures for my water system on our vessel for showers and galley needs. Our requirements were not for constant running such as spraying for long durations. Good Luck.
Question:	Will it pump saltwater
Answer:	The noise level is low and obviously it will determine where and what you are mounting it upon. My pump is located down in my engine room and its mounting is solid and within a noise barrier. When it runs it is not noticeable in my galley or in our state room. The pump is mounted just on the other side of the state room wall.
