Swissmex Knapsack Sprayer

Swissmex SW503 Lightweight Plastic Knapsack Sprayer

For high-pressure applications without strain: the “SW503” will not be beaten.

• By combining a piston with a protective diaphragm, this patented high-pressure
version of the best-selling SW501 piston knapsack is ideal for fungicides, glyphosate
and similar compounds which depend on extra-fine droplets for best penetration
and coverage.
• With pressures up to 12 bar it is the most versatile knapsack of them all.
• High-grade materials end all corrosion and reduce swelling, shrinking, warping or
dissolving of gaskets to the max.
• An extra-large filler port reduces risk of spillage.
• Piston seepage re-enters the tank to provide a degree of liquid agitation.
• The solid screw-on lid has a carrying handle, a lance holder, and a vent valve to
keep the operator from getting splashed in the neck.
• The pump handle folds up and away for safe transport and storage.
• The standard poly nozzle adjusts to variable spray patterns from a fine jet to a broad
misting cloud. Or use any commercial nozzle tips you like.
• Very low maintenance.
• Viton elastomers throughout
• A vast range of accessories and upgrades for any spraying job in agricultural spraying
• 15 litre Capacity
• Non-absorbent woven polyester 38mm wide carry straps
• 3/8-inch translucent hose
• 52cm Brass lance
• 4.9 kg dry weight

Awesome service and advice today. I'm just a residential buyer, I learnt a lot about spraying. If you need spray gear give these guys a go instead of the big green box.

Put in an online quote request for a number of products, Chris got back to me and put in the order. His service and the speed in which the delivery got out to me were second to none. can not recommend highly enough. Will head to welshpool rather than a certain store closer to me because of the excellent customer service :)
