Abstract
An improvement to surface marking devices for pumping and circulating melted thermoplastic material to various surfaces including roads, parking lots and the like is provided. The pump for melted thermoplastic is comprised of a cold section and a hot section. The hot section is connected to a fluid or electric motor, or alternatively, an internal combustion engine for providing rotation to the pump. The connection to provide rotation to the hot section is through the cold section, which is spaced away from the hot section and connected with shafting to provide rotation to the hot section. A heating jacket is secured to the hot section for transferring heat from an external source to the hot section. The spacing between the hot and cold sections provides the ability to rebuild the hot section of the pump without removal from the cold section and without removal from the vehicle to which it is attached.
