Zoeller shallow well and convertible deep well jet pumps feature sturdy construction, corrosion resistance, easy serviceability, and excellent performance. Well pumps are used to deliver water from a well to a home that is not connected to a municipal water supply. They are also commonly used for small-scale irrigation and livestock watering. Well pumps are available in shallow, deep well convertible, and submersible designs. Jet well pumps are surface pumps configured above the well system, while a jet assembly system (twin pipe or Packer depending on the application) is inserted into the well shaft. The main components of a jet pump are a nozzle, venturi, and the jet itself. The pumps components work together to create a vacuum above the water, which allows atmospheric pressure underneath to push the water upwards. Jet pumps can be either horizontally or vertically configured and are much the same size and shape as other pumps.

Believe it or not, Jet Pumps are not associated with the awful New York football team. They are referred to as such because they work similarly to a jet engine in the way they create large amounts of pressure. Jet Pumps are mounted above ground and are non-submersible. They are typically used to draw water from a well through a suction pipe in order to provide potable water or domestic water pressure. Other common applications (though certainly not limited to) include light commercial or residential irrigation and supplying water for sprinkler systems. Jet Pumps are typically more popular in warmer climates or areas with high water tables. Jet pumps come in two variations: deep well and shallow well. The type of jet pump most suitable for your application will be dependent on the depth of your well. Shallow well jet pumps are used to transport water from wells as deep as 25 feet. Deep well jet pumps are generally used for depths up to about 200 feet. Deep well jet pumps can move larger volumes of water more quickly and over longer distances than shallow well pumps. Please note that altitude can affect the specific depth to which a pump can draw water from. Deep Well Pumps can also be referred to as convertible jet pumps. This means that the pump can be used in either shallow or deep wells. In a shallow well setup, an ejector kit (or jet kit) is built in or attached to the pump. For deep wells, the kit is placed down in the well. This ejector kit helps force water up from the bottom of the well. If you already have a jet pump and you are looking to determine whether it is a deep well or shallow well pump, look at how many pipes are between the pump and the water source. One pipe indicates a shallow well pump while two pipes indicate a deep well pump. It is important to keep in mind that jet pumps should never run dry. Running a pump dry may significantly and permanently damage the pump. These pumps need to be primed first before they are ready to draw water. In order to prime your jet pump, first make sure the electricity to your pump is off. Next remove the priming plug on the wet end of the pump (or the side opposite the motor). Then fill the priming vent with water until it reaches the top of the vent. The idea behind this is to remove all the air from the pump housing. After the pump is primed, your pump is ready to go and you can turn the electricity back on to the pump. If the pump does not pull water within five minutes you may need to re-prime the pump.

Irrigation pumps are manufactured in a wide range of designs including centrifugal, submersible, jet and propeller models. They are used in domestic lawn sprinkling and water boosting applications as well as in large-scale agriculture and fire prevention. Irrigation pumps can draw on a municipal water supply or natural source such as a lake or pond and are available in electric or gas-fueled models. View our Irrigation Pump Video Video courtesy of learnengineering.org Choosing the Right Irrigation Pump Properly sizing an irrigation pump involves measuring your water source pressure (psi) against the flow (gph) and pressure (feet of head) requirements of your watering system and selecting the pump that will most efficiently connect the former to the latter. There are a number of on-line tutorials available to those interested in designing a basic irrigation system that is compatible with local water resources. Professional irrigation services are an option for applications with complex requirements. When it comes to selecting the pump at the center of the equation, pump curves are a good place to start. Pump curves are issued by pump manufacturers to illustrate a pump’s performance over a range of pressures and flows in feet of head and psi. The shape of a pump curve varies according a pump’s design. Pump efficiency is maximal at a particular combination of discharge and head and then drops below the maximum as the discharge rate increases. The objective is to select the pump with highest efficiency at the flow rate and pressure conditions required by your system. As a general rule, pumps with electric motors are driven at either 1750 or 3500 rpm (½ to 2 hp). Models driven at 1750 rpm are capable of lower head but higher discharge than those driven at 3500 rpm. IRRIGATION PUMP TYPES Centrifugal Pumps are commonly used for domestic irrigation because they can draw on water sources ranging from a municipal water supply to a creek and can deliver constant flow rates under a wide range of conditions. They move water through suction force generated by a rapidly spinning impeller and must be filled with water to remove air, or primed, in order to operate. The above video provides a detailed explanation of how a centifugal irrigation pump operates. Submersible Pumps operate underwater, often pushing water up from inside a well, and are commonly used in pressure boosting applications. What they lack in versatility they make up for in efficiency. Submersible pumps do not need to be primed and run quietly. Jet Pumps are terrestrial pumps with submersible components that make them ideal for applications with fluctuating water levels. A jet pump operates by directing water down an intake to cause water lift. Jet pumps do not need to be primed. Propeller Pumps use a propeller to move large amounts of water at low heads. Propeller pumps are among the smallest irrigation pumps. FEATURES Self Priming pumps don't require manual priming, which often involves pouring buckets of water down into the pump and pipe which can be a slow and messy process. A Flow Switch can be used with a booster pump to activate the pump and bring pressure up to an acceptable level when low water flow is detected in the pipes. A Timer makes it possible to save money by automatically watering a lawn during off-peak hours. They can also be set to operate when you're at work or away on vacation. A Pressure Switch helps to maintain a pump’s peak efficiency by turning it on when pressure in pipes is too low and turning it off when pressure is too high. Corrosion Resistance helps to ensure that pumps continue to function properly long after they are installed. This is an important feature in submersible pumps.
