MSO & MS-GAS Sprayers

The Dramm Heavy Duty MSO and MS-GAS sprayers might be small, but they pack a punch.


With a low-flow gun and high pressure, each atomizes the spray into fine droplets for even coverage.

The electric MSO operates at a maximum of 500 psi while the MS-GAS operates at a top pressure of 350 psi. Both are available as a pumpset with hose and gun alone or as part of a 20 gallon cart and tank package. Different hose lengths and gun options are available. Finally, both are available with our Bigfoot wheel package that adds pneumatic wheels and casters for more rough terrain.


The MSO and MS-GAS can use the standard MS-TG adjustable trigger gun or the L-5 Extension lance with 5 nozzle ring.

Both pumps offer pressure adjustment for flexibility when spraying.

The MSO has full pressure adjustment while the MS-GAS has three pressures: 110, 220 and 350 psi.
