Description

INTRODUCTION

A reliable flow of water is essential in many situations. For example, constant water circulation is crucial for residential and commercial buildings, including situations where the building has a water purification system and/or a water storage tank. In some cases, insufficient water flow or excessive water flow may damage water treatment systems, such as damaging membranes used in reverse osmosis devices. In addition, many agricultural applications require a reliable source of water. For example, it is essential to circulate and/or recycle water in greenhouses. In these situations, and others, pumps serve a critical role in maintaining the desired flow of water. Consequently, it is important to have a pumping system that is reliable in different situations, that is easily monitored, and that responds to changing circumstances and requirements for fluid flow.

The pumping system further includes O-rings and seals. Diameter of piping may be selected based on requirements.

FIGS. 1 and 2 show two views of the front of an example of a pumping system 10 according to the disclosure. FIGS. 3 and 4 show two views of the back of the system. FIG. 5 shows an exploded view of an example of a pumping system. In this example, the pumping system is about 26 inches wide by 21 inches deep by 54 inches tall.

In this example, system 10 includes first and second pump assemblies 12,14, and first and second control panels 16,18, In the example shown in FIGS. 1-5, the two pump assemblies are connected in parallel. In this example, each of the control panels includes touch screen 17. Water source inlet 22 is shown as well as outlet 24. These and other components are fastened to stand 32. In the views shown in FIGS. 1-5, pump assemblies 12,14 are mounted approximately vertical with the pump motors 13 positioned above the pump outlets 15. In other examples, as shown for example, in FIGS. 1447, the pumps may be mounted horizontally. In the example of FIGS. 1-5, source inlet 22 and outlet 24 are positioned close to the bottom of the system, and approximately horizontal, parallel to the ground. This positioning of source inlet 22 and outlet 24 allows two or pumping systems to be fluidly connected more easily by connecting the inlets and outlets of adjacently positioned systems.

In other examples, there may be more than one inlet and more than one outlet. For example, each pump assembly may receive source water through separate inlets. In other examples, water outputted by the pump assemblies may flow through separate outlets.

In this example, there are two control panels 16, 18 one for each pump assembly, where the control panels are placed one above the other, forming a pumping system with a compact profile. The control panels are positioned above the pump assemblies in this example. The exploded view of FIG. 5 shows that control panel 16 is assembled from two halves 16a, 16h. In other examples, a pumping system have a single control panel with two touch screens, one touch screen for each pump assembly. FIG. 10a and 10b also shows front and rear views of a controller with FIG. 10b showing the two halves 16a, 16b of a control panel with controller 19 also shown.

In this example, feed tubes 70,72 extend vertically from source inlet 22 and bend at the top, where one feed tube fluidly connects with each of pump assemblies 12, 14. Fans 28 are also shown, in this example, positioned adjacent to pump motors. For example, operation of pump motors may generate heat which are dispersed by fans 28.

According to the example shown in FIGS. 1-5, source water enters inlet 22 and flows through feed tubes 70, 72 to pump assemblies 12, 14. Water is pumped by the assemblies to pump outlets 15 which are fluidly connected to outlet 24, where the water may then be flowed for use in a desired application or for storage. In preferred examples, the system of FIG. 1 has an output of up to 40 gallons per minute (GPM) at a pressure of 50 pounds per square inch. In preferred examples, pumping systems of the disclosure have an output of from about one to 40 GPM, from about 5 to 40 GPM or from about 10 to 40 GPM, depending on requirements. The maximum water pressure tolerated by this system is about 200 psi.

FIGS. 6-9 show enlarged views of pump assemblies according to the disclosure to illustrate certain features of the assemblies. Pump assemblies 12,14 include motors 40, 42, mixing components, 44,46 and impeller components 48, 50. In this example, the impeller is cylindrical, extending from a first end connected to the mixing component to a terminal end having pump outlet 15,where the pump outlet is fluidly connected to outlet 24. Mixing components 44,46 includes ports 52,54 where water from feed tubes 70,72 flows into the pump assemblies. In preferred examples, the motor is a DC motor, such as a 3 horsepower 48 Volt DC motor. In this example, bleed valves 57 are inserted into a port on the mixing component. Pressure gauge 55 is also inserted into a port on the pump assembly, to monitor the water pressure in the assembly. If the water pressure is excessive, then the controller will shut down the system.

Motor drive shaft 71 is shown engaging with impeller drive shaft 67 in the mixing bowl interior 47 at point 77. Motor drive shaft 71 rotates impeller drive shaft 67 due to the engagement of the two shafts.

According to preferred examples, source water is fed into mixing bowl interior 47 through feed tube 72 and the rotating impeller drive shaft forces water through each impeller stage to increase flow rate. In this example; the impeller component consists of nine stages 61 that are connected to the impeller drive shaft 67. FIGS. 13a and 13b shows one example of components of an impeller stage including impeller 80 and cassette vane 90, where the two structures fit together. Both structures include orifices 82, 92 through which impeller shaft 67 passes. The impeller 80 and cassette vane 90 are configured to increase the pressure of water flowing through the pump assemblies.

Check valve 63 is present at the terminal end of the impeller component to prevent backflow of water into the impeller component.

The pump assembly may be formed from suitable materials for a particular use. For example, the pump assembly may be formed from stainless steel, but the mixing component may be formed from high density plastic.
