The impeller of the pump rotates with the motor shaft, cansing the water to fly out from its rim by centrifugal force. The rotation of the impeller creates a vacuum which "pulis" in more water. Part of the water is diverted back to the jet where it again passes through the nozzle and venturi - creating additional vacuum to draw in more water and delivering it at high pressure to the impeller. exceeds pipe on horizontal 4" DOUBLE Be certain no foreign stalling the unit.

The special adapter nipple furnished with the jet is not used on steel pipe installations, and should be discarded. Add sufficient piping, using pipe thread compound on the joints until proper depth is reached. A shallow well jet is available for use when the SEARS jet pump is installed on wells 20 feet or less to drawdown water level. NOTICE: Pipe compound can damage plastic components in pump.

Single pipe jets must be installed with steel suction piping in the well. Make sure all pipes are clean and ends are reamed before lowering any piping into the well. Look through pipe to make certain there are no obstructions. Venturi that protrudes from the jet body must be inserted in top (1-1/4" _ tapping. For ease of assembly, lubricate the small O-Ring on the end of the venturi and push the shallow well jet assembly into place. d. Align lugs on jet body with e. Place clamp During the process of lowering pipe into the well, always ifistall coupling on top end of pipe and above clamp. This will prevent accidental dropping of pipe into well. For standard tank installations, an air volume control is necessary and is connected to the 1/8" tapping in the jet body. Connect as shown in installation drawing, Figure 4, Page 5. SINGLE PIPE JETS - 2" OR 3" WELLS Before installing jet in well, it is necessary to soften jet leathers by soaking in water for a minimum of one hour. Attach the jet to the first length of suction pipe 1-1/4" (NPT). Use turned couplings (furnished) on 2" wells. Standard couplings may be used for suction piping on 3" wells. Use pipe compound on male threads only. Tighten each length of pipe as it is lowered into the well. Lower it to proper depth which is 10-15 feet below the drawdown water level. This is the level to which the water will drop install wbSfle the well is being pumped continuously.

IN THE WELL When using a foot valve, a priming in Figure 7 is recommended. Fill piping in well with water as each length is added, or after piping is complete in well. This serves to double check for leaks in piping and foot valve, and simplifies final priming of CASING until it fits over the flange A shallow well jet pump can be installed on a dug well, drilled well or with a driven point. SEARS shallow well jet pumps have a built-in check valve. In a dug or cased well, a foot valve and strainer is recommended and should be installed 5 to 10 feet below the lowest level to which the water vdll drop while the pump is operating (pumping water level). See Figure 4, Page 5. Your well driller can furnish this information. The strainer should not be too close to the bottom, or sediment may clog it. Before installing foot valve, check to see if it works freely. PIPE (OR PIPES) IN WELL INSTALLING steel clamp Illinois. Figure 7 tee and a plug as shown INSTALLATION NEVER run pump dry.

To do so can boil water inside pump, causing hazardous pressure in unit and possible scalding to persons handling pump. Be sure the total lift from the pumping water level to the pump does not exceed 20 feet if the pump is over the well, or less if the pump is offset from the well. Both figures are for sea level - the maximum lift at which the pump can operate satisfactorily, decreases with the elevation at the approximate rate of 1 foot per 1,000 feet of elevation; thus, if the lift is 17 feet and your elevation is 3,000 feet above sea level, you would then be pumping 17 plus 3 or 20 feet, which is still satisfactory for shallow well pumping.

Remove stainless steel clamp and remove the jet assembly by pulling it STRAIGHT out and away from the pump body. 5. Turn venturi A GASEOUS A good way of delivering gas-free water is to suspend a pipe, closed at the bottom and open at the top, surrounding the suction pipe (Figure 14). Since the gases rise in the well casing, the water sucked down through the pipe and into the suction pipe is free of gas. It is imperative that this type of well be vented to the outside of any enclosure. JET matter TO HANDLE In some localities well water contains gases which must be allowed to escape before the water is used. This can be done as shown in Figure 14. If pump has an air volume control, unscrew compression nut from fitting in lower portion of jet body. Tube will not pull out of fitting. 3. Remove 4. instruction and reassemble.
