The machines feature electric super sand pump (ESSP) systems that produce as much as 100 gpm (378.5 Lpm) for up to 50 percent faster coverage than diaphragm pumps.
Neal Manufacturing, a division of Blastcrete Equipment Company and a manufacturer of sealcoating equipment, gives commercial contractors increased efficiency with its heavy-duty ESSP 550T and 750T trailer-mounted machines. The machines feature electric super sand pump (ESSP) systems that produce as much as 100 gpm (378.5 Lpm) for up to 50 percent faster coverage than diaphragm pumps. They also are equipped with a convenient water tank hand-wand holder, which eliminates the risk of damage from leaking sealer to cars, the machine or other surfaces.
Neal Manufacturing’s ESSP 550T machines have a capacity of up to 550 gal. (2,082 L) of material, and the larger 750T machines have a capacity of up to 750 gal. (2,839 L). The high capacities reduce the time associated with refilling the tank on large projects and additional trips to the sealer manufacturer or distributor. In addition to the hydraulically driven, electrically controlled ESSP system, the units come with 75 ft. (23 m) of reinforced hose, a 6-ft. (1.8 m) hand wand and a six-nozzle spray bar. Users can add an additional hand wand or 87-in. (221 cm) spray bar for faster coverage. The spray bar can apply material in 16-ft. (4.8 m) passes for even greater efficiency on larger projects. Operators also can choose the optional 50-gpm (189 Lpm) electrically operated hydraulic piston pump (ESP), which delivers enough volume to operate two hand wands.
The ESSP transfers up to 100 gal. of material into the tank per minute. It also can process high sand loads, which is a requirement on some state, federal and Federal Aviation Administration (FAA) projects. V-twin, 18-hp (13.4 kW) Kohler Command PRO gasoline engines power the ESSP system and deliver 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, according to the manufacturer.
Neal Manufacturing designs its ESP and ESSP pumps for low maintenance and longevity, with 75 percent fewer parts than traditional air pumps. They feature leather cups that tightly seal the plates to prevent material from leaking. Unlike diaphragm pumps that require daily flushing to prevent their rubber seals from degrading, the leather cups in the hydraulic piston pumps will not degrade. Users only need to flush them once per year, which can save up to 30 minutes per day. The seals last up to 200,000 gal. (757,082 L), depending on the sand load.
The pumps include 2.5-gal. (9.5 L) material filters that capture more debris so the machines can spray longer between filter cleanings. They also feature Neal’s Generation III pump heads. The Generation III controller serves as the brain for the reciprocating cylinder — the unit that drives the material pump — and features a specialized, time-tested and reliable design for uninterrupted pumping power. In addition to more volume, Neal’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.
Both sealcoating machines feature an in-line surge tank that reduces material surging to ensure continuous flow of material for uniform coverage. The machines’ hydraulic agitation system 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. The shaft of the agitator also is made with solid steel for increased strength, durability and longer wear life.
The control panels on the sealcoating machines allow users to change the direction and speed of the pump and agitator. They also allow operators to accurately control the water cleanup system.
Large indicator lights alert users to the status of the machine from long distances. Users can access the tank through the 21-in. (53 cm) square manway that includes an interior safety lid and sandbag splitter.
Neal Manufacturing uses high-gauge structural tube steel to build its trailers. The tubular construction increases strength, which in turn minimizes the risk of cracks and structural failures that are more common in frames with C-channel construction. In addition, they can be towed from job to job with a standard 2-5/16-in. (5.8 cm) ball hitch or an optional pintle hitch. They also have breakaway safety switches that automatically apply the brakes and prevent the trailers from rolling out of control should the trailer get separated from the tow vehicle. The trailers also are equipped with the appropriate department of transportation lights for safe travel.
To ensure its customers know how to properly operate and maintain the machines, Neal Manufacturing also offers free training seminars at its Anniston, Ala. location.
