Pressure Per Square Inch (PSI)

With the 61800 you can select 30, 45, 60, or 80 psi. You can find the selector is inside tank, but remember that this is a manual pump and not a battery operated backpack sprayer so as your arm gets tired, you may not be applying a consistent force like a battery powered sprayer would.


The 4 gallon translucent tank makes it easy to see the amount of fluid held inside the tank.

The tank has a large opening to make it easier to add and drain liquid from the tank.  It also has a strainer that keeps debris from falling inside the tank.  They have also included an in-tank filter to prevent clogs from getting into the hose.

Padded shoulder straps makes carrying the tank a lot more comfortable.

Stream Size

The Chapin 61800 gives you a 25-Foot Horizontal And 23-Foot Vertical Spray Stream with each pump.


A 3-Nozzle Kit is included with each sprayer which allows you to spray from a fine mist, to a straight stream and to a broad fan.
