Frequently Asked Questions About Submersible Pumps

Quick answers:

* A submersible pump is a pump that is designed to be immersed in fluid. The motor on a submersible pump is attached directly to the pump body, allowing the whole assembly to be submerged.

* A submersible pump has a system of mechanical seals that prevent fluid from getting into the motor, resulting in short circuits.

* A submersible pump typically has the shape of a cylinder. The sealed motor of a submersible pump makes up the lower half which is connected to an above ground power source, controlled by wires. The upper half is the actual pump which is comprised of a series of impellers, each separated by a diffuser, that force fluid up a hose or pipe.

* A submersible pump may fail for the following reasons: Tank size is too small, Short cycling, Running dry, Lightning strikes, Improper selection of high head pumps in low head applications.

* A submersible pump is used in many applications. A single stage submersible pump is used for sewage pumping, slurry pumping, drainage, and general industrial pumping. A multiple stage submersible pump is lowered down a borehole and used for water extraction or in water wells.

* A submersible pump has the reputation of being exceptionally reliable. The technology of submersibles is well developed, resulting in few problems and difficulties. It is not uncommon for a submersible pump to function well for 25 years before requiring service.

* A submersible pump is best serviced by a professional, in that the whole unit must be extracted from beneath the ground for inspection.

Thank you for providing vacuum pump search engine. Maybe the website's content is rich. But it appeared some "faulse mark" mared with red. So it is not convenient for me to browse.

Hello Maylinda, I do not know what you mean by "faulse mark" Can you explain? Perhaps you can make a jpg of a screen shot that shows the error and sent it to me at: jchaurette@pumpfundamentals.com

Very useful information shared

I will suggest a couple things you might check. First, remove the fuse box cover under the hood and look at the location for the fuel relay. Under the relay will be some numbers, one for each of the four prongs. The spot where #30 shows to be on the cover is where you have power. Diagonal from there will be #87. With the relay out, use a small wire and jump from the #30 to the #87. While doing this listen for the fuel pump to run. You should hear it at the engine also. If this makes the pump to run, then the pump probably is ok. Next put the relay back in. Try to start your truck. If it starts, let it run until it quits then turn off the key. Wait for about five minutes then have someone turn on the key while you are listening for the pump again. It should pump for approximately 2-3 seconds to pressurize the fuel to the engine when the key is turned on. If this happens you know the pump, relay and regulator are all doing fine.
