| INTERNAL PUMP DESIGN FOR POND VACUM A QUICK EXPLANATION One of the main reasons for the high price of commercial pond vacums is the need to achieve an airtight seal on the vacum container in order to enable sucking the water from the pond edge up to the cannister and through. Manufacturers solve this with expensive seals and heavy duty plastic castings. To solve the airtight problem I simply put the cannister in the pond if it leaks a little it only sucks in a bit of water. If for some reason you dont achieve adequate suction you can tape the seam around the lid with plastic duct tape, check bulkhead nuts are tight, wrap teflon tape around pipe connections before slipping on hose and tightening clamps. (the hose can also be glued to fittings) ASSEMBLY INSTRUCTIONS FOR SUMP PUMP OPERATED POND VACUM LID Look inside the rim of the lid and you will see a ridge running along the outside flap, this ridge holds the lid on to the bucket. Note where the ridge ends and make small cuts in the lid according to diagram ( pv 1 ). These allow the lid to be removed much more easily. Be carefull to cut only the outer rim of the lid and only to the lip. Drill hole in center of lid to receive bulkhead fitting (pv 2 ) for vacum hose connection. Double check to be sure of hole size by drilling a practice hole in a piece of scrap and checking fit of bulkhead fitting before drilling actual lid. Drill hole for watertight electrical fitting. Double check to be sure of hole size by drilling a practice hole in a piece of scrap and checking fit of watertight electrical fitting before drilling actual lid. PUMP The cord on the pump must be fed through the watertight electrical fitting in order to do this the power cord plug must be removed then fed through all parts of electrical fitting in correct order. Before reattaching a new plug BUCKET Drill hole in side of bucket to receive bulkhead fitting (pv 3) for vacum hose attachment. Drill about 2 1/2" down from the top of bucket to allow for flange on bulkhead fitting Double check to be sure of hole size by drilling a practice hole in a piece of scrap and checking fit of bulkhead fitting before drilling bucket. Make sure you have the appropriate fitting or adapters for the hose you will be using as a vacum. SCREENING OUT DEBRIS The main idea of filtering or screening the debris is to remove the larger particles that may cause a blockage of, or damage to the pump. As the rest of the material removed is very high in nutrients it is a good idea to pump it to a place that it may be of use as plant nutrient. The lawn, flowerbeds, planters it also greatly enriches the compost pile In the model on the drawing i have used basicaly the same design as you may see in a pond filter system this is by no means the only method of filtering the chunks out and you are welcome to change or improve it. Due to the high density of material being removed from the bottom of a pond it is not uncommon for the cannister to fill up rapidly and the vacums speed and efficiency to drop off. ASSEMBLY Assemble all parts as depicted on drawing . Dont worry about sealing the connections as they will be underwater and a slight leakage is okay. (if there is a problem with leakage the fittings can be siliconed ,teflon taped or glued later) VACUM HEAD AND HOSE Build the vacum head as described in the syphon vacum plans but substitute a 1" line in place of the 1 1/4" line. With a syphon it takes a larger line to get the required volume. In the pump model a 1"line is fine and a little easier to manouver around. I find a plastic (950 ml. or 1 quart) gatorade bottle fits the 1" hose quite well although you are welcome to adapt anything you want. I recomend you use a clear plastic for the vacumhead so you can see when the water going up the vacum clears. OPERATING INSTRUCTIONS DANGER BEFORE OPERATING POWERED POND VACUM BE SURE YOU ARE PLUGGING IN TO A G.F.I.C. PROTECTED ELECTRICAL CIRCUIT EXTREME ELECTRICAL SHOCK HAZARD USE ONLY A SUBMERSIBLE PUMP After completing assembly of all parts and attaching the vacum hose. Take the whole unit to the pond side. I strongly suggest having a helping hand for the first few times until you get the hang of operating this unit. Decide what to do with the removed water and make those arrangments ( I.E. attach a garden hose to pump and run it to the rose bed or whatever) Tie a line to the handle of the bucket and tie this to a stake or peg to keep the bucket in place and hanging below the surface. I have a broken golf shaft about 3' long it has a nice rubber handle and a narrow end that is easy to stick in the ground. set the vacum unit in the pond. It will probably float a little Insert garden hose from house in vacumhead and begin filling with water, as the bucket fills it should sink and eventualy water will start coming out of the pump. When this happens put the vacum head underwater with the hose still running in it then turn on the pump and keep the hose running until all the air has left the line and the vacum is running smoothly. Have helper turn off the hose and remove it from vac head . Proceed to vacum pond keeping the vacum head under water at all times or you will have to start it again. If you are vacuming and it sudenly stops sucking usualy it has lost its prime due to an air bubble from lifting the vac head. Check for blockages then insert the garden hose in vac head and start the procedure again. The vac bucket can get full or plugged occasionaly so keep that in mind. Also if you find it is plugging to often you may have to change the type size or amount of screens or filtering medium in the bucket. |
