4. Flojet Pump Assemblies 2100 Series Demand Pump OPERATION 1 Allow pump to prime with discharge line or spray valve open to avoid an airlock 2 A built in pressure switch will automatically turn the pump off when the discharge valve is closed pressure reaches the set cutoff point and will turn on when the pressure dropsbelow the cut in point In the bypass model fluid recirculates 3 If the supply tank is empty the pump will continue to run Running the pump dry will not damage the pump Turn off manually NOTE The pressure generated by the pump is dependent upon the flow of the spray nozzle An undersized spray nozzle or a lance spray gun adjusted to produce too fine a spray will cause the pump pressure switch to cycle on and off and create a pulsating flow from the pump To obtain a smooth flow and constant operating pressure adjust the nozzle setting on the lance spray gun or select a larger size spray nozzle SERVICE GUIDELINE Disconnect power first 1 To disassemble remove six pump head screws 18 rotate bearing cover 9 so drain notch is aligned with cam bearing assembly set screw 7 2 Loosen set screw use 1 8 size Allen Wrench Slide pump head off shaft 3 Pistons 10 should always be replaced when new diaphragm is installed 4 Replace worn parts and reassemble Be sure raised side of diaphragm faces the motor and radiused corner of pistons face diaphragm 5 Hex stem of inner piston 10 must be aligned free to ente
5. The following formula will be useful in determining this amount and therefore achieve the correct dilution ratio Tank Volume x Dose per Hectare Chemical per tank in Litres Calibrated application rate of sprayer in L Ha For example if the chemical must be applied at a dose of 2 Litres per Hectare your tank volume is 100 Litres and your sprayer is calibrated for 220 Litres per Hectare then 0 9 Litres of chemical must be added to the tank to obtain the correct dilution The formula will therefore look like this 100 x 2 0 0 9 Litres of concentrate per tank 220 Similarly if the chemical must be applied at a dose of 2 Litres per Hectare your tank volume is 100 Litres and your sprayer is calibrated for 200 Litres per Hectare then 1 0 Litres of chemical must be added to the tank to obtain the correct dilution The formula will now look like this 100 x 2 0 200 1 0 Litres of concentrate per tank Page 6 Cleaning Flushing and cleaning your equipment is an important part of your sprayers maintenance plan and also helps reduce the possibility of contamination when changing chemicals The sprayer tank should be drained and flushed at the end of every day of spraying Changing Chemicals When changing from one chemical to another it is important to thoroughly clean the sprayer s tank and hoses to minimise the risk of contamination After rinsing the sprayer with clean water fill the tank to around 1 3 full with a 1

9. ication rates vary from one product to another therefore it is vitally important to read your chemical manufacturers literature In order to apply the spray correctly certain other variables must be considered These include nozzle size discharge pressure and vehicle speed In order to assist with safe and accurate use of your equipment the following information and reference chart is provided Before using the chart you will need to know The correct Application Rate in L Ha in accordance with your chemical manufacturers instructions Your desired vehicle speed in Kph The pressure range of your sprayer in bar Now proceed as follows Run your finger across the top row of figures in the chart until you find the one that matches your desired vehicle speed Now run down the column below your vehicle speed until you find the number that is closest to your recommended chemical application rate in L Ha Next run back across the chart and note the pressure in bar and nozzle size recommended to achieve the correct coverage You will notice for example that at a soeed of 6 Kph an application rate of 121 L Ha can be achieved with a 4110 12 nozzle at a pressure of 2 0 bar Note also that if we increase the vehicle speed to 8 Kph we must either increase the sprayer pressure or select a larger nozzle size to achieve the same coverage N O 56 43 Lilac 4110 08 61 46 66 49 f 77 57 Brown 86 63 4110 10
