IMPORTANT INFORMATION ABOUT SPOT SPRAYERS 


 
Silvan Spotpak’s feature a positive displacement diaphragm pump with a pressure sensing switch. The pressure switch 
interrupts power to the pump when the system pressure builds towards maximum and power is resumed to the motor 
when the pressure falls. 
 
When the spray lance trigger is depressed fluid is released and the pressure will drop allowing the pressure switch to 
resume power to the pumps motor.  
 
Depending on your spraying requirements you may need to change or adjust the nozzle to suit your desired droplet size or 
spray pressure. 
 
Spotpak’s fitted with the Smoothflo model pump are designed not to pulsate and should stop pumping when the valve or 
spray gun trigger is released. If the pump fails to stop pumping  see the trouble shooting section.
