HDP 1500 Skid-Mounted Sealcoating Machine Delivers Impressive Capacity, Exceptional Efficiency

In News by Neal Manufacturing

The 1,500-gallon capacity of the 1500S skid-mounted sealcoating machine reduces the time associated with refilling the tank on large projects and the number of trips a contractor needs to make to the sealer manufacturer or distributor. In addition, the unit’s heavy-duty aggregate pump system, or HDP, features a variable speed control and produces as much as 100 gpm, the fastest transfer rate among piston pumps on the market. With this system, operators can cover areas up to 40 percent faster than diaphragm pumps.

The 1500S features an in-line surge tank that reduces material surging to ensure continuous flow of material for uniform coverage. The hydraulic agitation system with chain reduction features a unique three-blade design; the blades are offset to ensure two blades are in the material at all times, which produces a more thoroughly mixed product. In addition, the shaft of the agitator is made with solid steel for exceptional strength, durability and long wear life.

The control panel on the 1500S allows users to change the direction and speed of the pump and agitator, and provides accurate control of the water cleanup system. The contractor can access the tank through the 21-square-inch manway which includes an interior safety lid and sandbag splitter.

The hydraulically driven, electrically controlled HDP system features Generation III pump heads that serve as the brain for the system and feature a specialized, time-tested design for reliable pumping power.

The pump includes 2.5-gallon material filters that capture more debris so the machine can spray longer between filter cleanings. Further, the HDP pumps have 75 percent fewer parts than traditional air pumps. Their leather cups tightly seal to the platesto prevent material from leaking. While diaphragm pumps require daily flushing to prevent their rubber seals from degrading, the leather cups in the hydraulic piston pumps only need to be flushed once per year, which can save up to 30 minutes per day. The seals last up to 200,000 gallons, depending on the sand load.

Neal Manufacturing’s pump offers more power, increased suction and the ability to spray larger volumes of materials with heavy sand loads, either through multiple hand wands or a spray bar. The unit comes with 75 feet of reinforced hose, a 6-foot hand wand and a six-nozzle spray bar. The high-volume pump also can supply material to an optional distributor bar, which is capable of an 11-foot-wide pass, or to a second hand wand for greater efficiency. An optional hose reel can store 75 feet of hose.

An 19-horsepower Kohler Command PRO® V-Twin gasoline engine powers the HDP system and delivers high torque for strong material mixing in the tank. The pump also provides on-demand action; since it pumps only when pressure drops during spraying, it consumes less horsepower, reduces fuel consumption and increases engine life.

To ensure its customers know how to properly operate and maintain the machines, Neal Manufacturing offers free training seminars at its Anniston, Alabama, location.

All machines are tested under load before being shipped to its customers.
