Modular Spray Truck System


Modular Tank Systems

Gregson-Clark modular spray systems feature a compact frame for the pump/engine and hose reel that is separate from the tank or tanks. For vans, flatbeds, and enclosed body trucks, modular systems provide an ideal solution. The pump/engine and hose reel are typically positioned curbside for easy access and the tank or tanks cans be positioned for ideal weight distribution and ease of filling. All modular frames have provisions for easily bolting down through the truck bed.

Modular Pumping Units:

The modular pumping unit (MPU) features a compact universal frame that can accommodate a hose reel or pump/engine on the top or bottom.

For systems with two tanks, 3-way ball valves are used on the suction and bypass lines to provide tank selection and inter-tank transfer. Systems with three or more tanks require a valve manifold.

For vans, enclosed body trucks, our modular pumping units can be positioned curbside to allow east access to all controls. Units can be equipped with a fast-fill line and dispensing nozzle for filling a ride-on sprayer.





Modular Tank Assemblies:

PCO style modular tank assemblies are available in 35, 50, 100, 150, 200, and 300 gallon sizes. Tank assemblies include frame, tank, straps, and suction and agitation lines installed. Leg tanks are also available in 510, 735, and 1,035 gallon. Added to an existing sprayer, a modular tank is an inexpensive way to increase capacity and allow for two separate spray solutions.
