Any Suggestion for aHigh Efficiency Submersible Pond Pump?
We Previously have a Prima 3400 XL. Now It turns on and off on the GFCI.
Its feature:
Filter pump with a flow at 3 head of 1000gph makiit suitable to run filters of up to 2500 gallons capacity – max flow 1800gph and max head 15
The pump was run dry when there was a blackout of electricity. Any suggestion for a pump that can handle some solids (fine leaves) and does not die when the water is out. Perhaps turns off automatically when there is no water.
The pump is for a cascading waterfalls about 500 gallons water in it. 30 feet in length. Around 3 feet vertical height from the top to the bottom of the stream.
High efficiency is a plus coz it runs 24/7
I got tired of these “pond pumps” that you pay so much for just because they’re for a pond. I went to Ace Hardware, they have a big line of submersible pumps that are reasonably priced. I got a 1/2 horse that pumps 2550 gph continuously. It’s been going for three weeks now, non-stop. For $99.00 on sale.

The submarine that can fly like airplanes have been promoted in the science fiction entertainment for many years. Already in the 1960s, in the Voyage to the Bottom of Sea film and television series, a subgroup of flight often used for exploration, is contained in the belly of a large submarine called the Seaview.
A futuristic ship that is both waterproof and can fly rescued from calamity James Bond films identified in this genre. Of course, a submarine that can become on an aircraft is still just fantasy, science fiction and does not exist anywhere in the world today.
The difficulty in creating such Invention is the reason why a submarine flying today exists only in the imagination of Hollywood entertainment. The construction of such vehicle require material needed to meet the unique and diverse needs of both submarines and aircraft.
The aircraft are designed to be light and dynamism. Submarines, on the other hand, need weight to remain submerged and thick to sustain the pressure of being underwater. The differences in the density of water and air at high speeds, and make the load requirements of aircraft and submarine design requirements that actually work against each other. That's why the Navy did not in an attempt many years ago to build a submarine that can fly.
In 1964, the Office of Naval Weapons awarded a contract for Convair to examine the feasibility of flying a ship "submersible," which had been called the "sub-level" by participating in the project. Convair The study found that the vessel was "doable" and a contract was awarded to the company, but two years later, the Navy canceled the project.
However, the Defense Advanced Research Projects Agency (DARPA) thinks the time is now right that contractors Bid on the possibility of fiction Hollywood yesterday a science fact today. Darpa has a budget of $ 3 million and the Agency has already received bids from defense contractors in response to the Request for Proposal (RFP) to build a submersible aircraft of the future.
The Defense Agency wants to build a submersible aircraft that would combine the key capabilities of three platforms: (1) the rate and extent of an aircraft, (2) the ability of a ship, and (3) the stealth of a submarine. By combining the beneficial features of each platform, DARPA hopes to develop a craft that will significantly improve the tactical advantage of the United States insertion missions the coast.
The proposed craft hold eight soldiers, plus all their gear and can support a floating surface vessel 72 hours. There will be an aerial range 1000 miles and 12 miles wide submerged. Certainly, a flying submarine used to great advantage in the deployment of operations special military forces in difficult and dangerous missions.
The world is on the verge of a revolution in building materials. Nano technology research is to produce innovative new building materials in the laboratory that is stronger than steel at a fraction of the weight.
So, time may be right to make the Hollywood science fiction fantasy a reality. In fact, it's another attempt by the U.S. military to try to build the submarine flight.
