Features may include:

• Industry-exclusive diaphragm or centrifugal pump options

• The John Deere SelectSpray™ Series are the only sprayers in the golf industry to offer the choice of centrifugal or diaphragm pump to meet specific applications or operator preference.

• Diaphragm pump

• If spraying turf paint, using a walking spray boom or just personal preference, the diaphragm pump is the option to choose. Diaphragm pumps provide lower flow rates, but can achieve much higher pressures compared to centrifugal pumps.

• The 113.9-L/min (30.1 gpm) diaphragm pump provides plenty of flow for turf applications, but also can generate 290 psi (20 bar) of pressure. The pump is powered by a hydraulic motor and features a three-diaphragm configuration for excellent efficiency and smooth operation. The ability of this type of pump to handle thicker fluids, and its ability to run dry with no seals to fail, makes it a popular choice for tough spray solutions, such as turf paint.

• Diaphragm pumps are positive displacement pumps, meaning that every revolution is going to pump fluid out of the pump outlet. As a result, a pressure relief valve is added to the main sprayer control valve assembly to protect the system if the system is dead-headed.

• The relief valve pressure is adjustable up to 290 psi (20 bar), but should initially be set at 200 psi (13.8 bar). The spring-loaded relief valve opens a bypass line back to the tank when the system pressure reaches the relief pressure.

• The pistons operate in an oil bath for long life and optimum lubrication. The diaphragms should be replaced annually or every 400 hours, whichever comes first. A standard suction strainer helps increase the life of the diaphragms by filtering debris out of the spray tank before it reaches the pump.

• If looking for simplicity without sacrificing performance, the centrifugal pump line may be the right choice. Centrifugal pumps are reverse from diaphragm pumps in that they are higher-flow, lower-pressure pumps.

• Flow rates can approach 397 L/min (105 gpm), while maximum pressure can reach approximately 95 psi (6.6 bar).

• Centrifugal pumps for the SelectSpray Series are offered in two models: cast iron or stainless steel. Cast-iron pumps are the choice for general all-purpose spraying, whereas the stainless-steel upgrade is the choice for more corrosive chemicals, such as chelated iron.

• The centrifugal pumps are powered by a hydraulic motor and come standard with a bleed line that purges air from the pump automatically, making priming the pump a breeze. Since a centrifugal pump will not pump fluid if the system is dead-headed, plumbing is simplified and no relief valve is required.

• Lifeguard™ silicon-carbide seals allow both the cast-iron and stainless-steel centrifugal pumps to be intermittently run dry without failing the seal. Another added benefit of these durable pumps is that they require minimal maintenance—there are no diaphragms to replace and no oil to change.

• No matter the application or personal preference, the John Deere SelectSpray Series offers a premium pump to meet the needs and demands of the operator's application.

• Choice of Gen2 TeeJet® automatic or manual application rate-control systems
