990 Series

ESSP-990 Asphalt Sealcoating Machine and Applicator

Skid or Truck Body


The ESSP-990 skid system has many available configurations to suit your needs. The standard model has the engine/pump in the front (as shown). Or you can opt for a custom model with the engine in the rear making the unit shorter for a smaller bed. The ladder and catwalk were designed for safety and accessibility.

These units are also available with a Truck Body Package customized to the exact specifications of your truck chassis. If you can dream it, we can build it.

As an option, agitator paddles can be equipped with 38-inch Neoprene squeegees for maximum material mixing and removal. The control panel can be located at a lower position for ground access when tank is mounted on a truck.

The "Power Plant" for the ESSP-990 is the 16 HP Briggs & Stratton® V-Twin OHV. A Honda® engine can be substituted. All come with electric key start.

The standard model has the engine in the rear under the dash panel. An engine-in-front (EIF) model is available with the engine compartment in front of the tank just like a trailer model.
