All of our pumps are High pressure from 700 psi -1000 psi. We do not carry any low or mid pressure pumps( 70-250  psi.) at Smart Mist USA. All pumps have a low water shut off safety feature. For reference, see the article " High pressure vs. mid pressure misting systems "

Now starting from our smallest :

SM-050E: This  economy .13 gpm, 700 psi,  high pressure, 2 piston pump features key type remote and 3 pre-set intervals to choose from.  It is very small and quiet and a great value for a high pressure pump. Uses include a small area, misting fan, or umbrella mister. 

SM-050: This small yet full featured .13 gpm ,1000 psi, 3 piston pump features touch panel and remote control. It has 3 pre-set intervals to choose from and has a water cooled transmission. It's perfect for small areas or to power misting fans etc. 

SM-050S: This pump has the same features as the SM-050 with increased capacity of .17 gpm and an industry first " VFD ( variable frequency drive) " for this size pump. Within its maximum capacity, you can use nearly any size and quantity nozzle because the motor and pump will adjust depending on the demand. In addition, you can control the pressure from the remote. This is truly an incredible machine.

SM-100,150, 200, 300 : These are our flagship App models. Please read the article " The magic of interval spraying".  These incredible pumps have every feature available in addition to the ultra convenient app control feature with adjustable interval spraying.  The pumps are all identical except for their output capacity. New this year is our exclusive SM-200 which bridges the gap between our SM-150 and SM-300. Now we can match the perfect pump based on the size and quantity of nozzles in your system.
