Abstract: An external by-pass circuit for a positive displacement pump includes a flow diverter valve coupled to the pressure port of the pump. The flow diverter has an end coupled with a high flow output and another end coupled with a low flow output. The low flow end includes a by-pass arm coupled to and input flow fitting. The flow diverter valve further includes a ball valve to direct fluid to either the high flow or low flow output. The input flow fitting is coupled to the suction port of the pump at the one end and couples with a fluid source at the other end. The input flow fitting includes a flow control arm which includes a needle valve to selectively control flow within the flow control arm. The flow control arm also includes a by-pass fitting fluidly coupled with the by-pass arm of the flow diverter valve.

Abstract: A backpack sprayer system includes a mounting bracket having a battery receiving fixture to receive a battery. A first tank is mounted to the mounting bracket and holds a diluent. A second tank is mounted to the mounting bracket and holds a liquid concentrate. A mixing manifold is mounted to the mounting bracket and has a first inlet fitting to receive a fixed amount of diluent and a second inlet to receive an adjustable amount of liquid concentrate. The fixed amount of diluent and adjustable amount of concentrate are combined to form a mixed solution and the mixing manifold includes a mixed solution outlet. A positive displacement pump is mounted to the mounting bracket and a suction port coupled to the mixed solution outlet and a pressure port fluidly coupled with a spray device. A control unit is mounted on the mounting bracket and receives power from the battery.

Abstract: A sprayer system includes a diluent tank, a mounting bracket mounted to the diluent tank and a concentrate tank mounted to the mounting bracket and diluent tank. A mixing manifold is mounted to the mounting bracket and has a first inlet fitting to receive a fixed amount of diluent and a second inlet to receive a liquid concentrate. The diluent and concentrate are then combined to form a mixed solution. The mixing manifold includes an outlet. A positive displacement pump is mounted to the mounting bracket and has a suction port fluidly coupled to the mixed solution outlet. A pressure port may fluidly couple with a spray device. The second tank may be separable from the first tank and mounting bracket without requiring removal of the mixing manifold or positive displacement pump.

Abstract: A backpack sprayer system includes a mounting bracket having a battery receiving fixture. A first tank is mounted to the mounting bracket and holds a diluent. A second tank is mounted to the mounting bracket and holds a liquid concentrate. The second tank is selectively, individually removable from the mounting bracket. A mixing manifold is mounted to the mounting bracket and has a first inlet fitting to receive a fixed amount of diluent and a second inlet to receive an adjustable amount of liquid concentrate. The diluent and concentrate are combined to form a mixed solution with the mixing manifold including a mixed solution outlet. A positive displacement pump is mounted to the mounting bracket and has a suction port coupled to the mixed solution outlet and a pressure port coupled with a spray device. A control unit is mounted on the mounting bracket and receives power from the battery.

Abstract: A dual chamber backpack sprayer system includes first, second and third tanks, and a pump unit. The first tank includes a first tank housing defining an open internal volume configured to hold a diluent therein. The second tank is dimensioned to be received within the internal volume of the first tank and is configured to hold a pressurized fluid therein. The third tank includes a third tank housing configured to hold a liquid concentrate therein. The pump unit is fluidly coupled to the first tank, the second tank and the third tank. The pump unit is configured to receive the diluent from the first tank and the liquid concentrate from the third tank to produce a mixed fluid. The mixed fluid is delivered to the second tank as the pressurized fluid.
