Pump water from your shallow or medium depth well to a holding tank using this Red Lion Convertible Jet Pump and Injector Kit. This unit is designed for use with both shallow wells up to 25' deep, or in deeper wells up to 90' deep with the included injector kit. The cast iron body ensures durability, and the glass filled thermoplastic impeller creates an efficient water flow. An attached pressure switch keeps the pump running between 30 and 50 PSI, and has an automatic shut off function to protect the unit from sudden pressure changes. The included injector kit attaches to the front of the pump for shallow wells, or can be installed within your deeper well for more lift. Its heavy duty, single phase motor can use either 115 or 230 volts, offering a reliable unit, and its 1 horsepower, 3450 RPMs will meet all your home water supply needs. Use a single 1 1/4" pipe on the inlet for a shallow well, or remove the injector kit from the inlet and use a dual 1 1/4" pipe for deeper wells. For significant runs, increase the pipe size to 1 1/2" to maximize water flow. The top outlet accepts 1" MNPT pipe. Place this pump on a level surface near your well, secured to the ground with its integrated bottom bracket, or place it atop a water storage tank. Move water from your deep or shallow well to your holding tank with this Convertible Jet Pump and Injector Kit. Two year limited warranty.

Dynamic Head

The effect of the Earths gravity on the "lift" or head pressure is fairly simple; for every vertical foot of distance the pump moves the water you are adding one foot of head pressure so the ratio is a 1:1 ratio. The effects of the friction, caused by water as it travels through your hose or pipes, on the total head pressure is a little more difficult to calculate especially as there are slight variations in pipe friction in different hose materials and the smoothness of the inner bore. Basically. for every ten feet of pipe through which the water has to travel travel horizontally will contribute 1 foot of head height; the ratio of the pipe friction loss is a 10:1 ratio.

Plumbing fixtures and bends and corners in your hose also increase the total head you must calculate to ensure the proper final volume from your pump. Every corner with a 90 degree elbow in your plumbing will add 1 foot of head pressure  with a 1:1 ratio. 45 degree elbows, tees and even insert couplers can all have an impact on the final flow.

If you install a pump 40 feet away from the top of your waterfall which is 6 feet above the pump and the tubing is a single run of 40 feet horizontally then you add 4 feet of head for the tubing length (the 10:1 ratio) to the 6 foot differnetial between the pump location and the final height of the waterfall so your final total dynamic head calculation would be 10 feet. This means your final volume of water flow in this water feature or application would be the volume of flow on the performance curve that equaled the gallons per hour at 16 feet. This volume will certainly be much less than the initial volume the pump can move at an open flow or a zero head.

If in the above example your 40 feet of horizontal tubing run also required 3 elbows of 90 degrees then an additional 3 feet of theoretical head would be added and your final flow result would be at 19 feet on the performance curve of the pump. In this example you would want to choose a pump that has the desired GPH rating at 9 feet of head pressure.  Tubing size is also an important factor in accounting for head pressure loss, in general you should never reduce the diameter of the tubing below what the output size of the pump is, this will drastically increase head pressure, and reduce pump performance.  For maximum pump performance, using the largest tubing that is practical is the best choice. A best practice is to use a hose with an inner diameter that is the same as your pumps outlet fitting.
