Get more pressure, volume, distance, and speed using a pump with 5x fewer parts!

Dual diaphragm pumps do have a place (we offer them with our 300 Series), but when you're a professional taking on big lots, two and three at a time, you don't have time to spare. Have you ever tried to pump a sealer/sand mixture with an air-powered pump? It doesn't work. Our 50 gallons ⁄ minute ESP and 100 gallons ⁄ minute ESSP piston pumps are simple in design but vastly superior in performance. Complemented by a 21⁄2-gallon surge tank, these pumps spray a smooth stream. That consistency is key to an even-looking coat.

Pushing out a gallon for every stroke is more than anyone needs, but do you want to constantly run your pump at maximum? That's asking for downtime. Speaking of downtime these pumps contain 11 pieces. Six of those are made of steel, so you only need to replace the leather cups every one to three years.

Features

• Hydraulically driven piston pump is designed for high sand load (up to 16 lbs. per gallon).
• "On Demand Pump" strokes only when pressure drops from spraying. Each stroke moves a gallon of sealer.
• Requires NO regular flushing or maintenance—no need to clean out until the end of the season!
• Seals last through approximately 200,000 gallons, and then are easily rebuilt with 5 seal cups.
• 75% fewer parts than an air pump means easier troubleshooting and simple, fast repairs with solid-state technology.
• Fastest transfer rate; either 50 GPM or 100 GPM.
