Replacing the ST Series, Mayco LS Series pumps have volume outputs from 40 to 60 cubic yards per hour and handle aggregate from 3/8 to 1½ inches in diameter. Horizontal pumping distance reaches 1,200 feet, and vertical pumping distance reaches 300 feet. Improvements include high velocity heat exchangers to cool the hydraulics, a 40-gallon fuel tank and an improved lubrication system.
