Overview

Double wall hoppers (D) can be mounted on the back or side of the frame (A) to gravity feed spray material to the Xtreme lower (B). Feed pumps (H) and agitators (J) can be mounted on top of the hoppers to pressure feed spray material directly to the pump.

A strainer inside the hopper (D) prevents objects larger than 1/4 in. from clogging or damaging pumps. When the XM sprayer is running, spray material exits the hopper through the fluid inlet assembly or transfer pump and circulates through the lowers (B), mix manifold, fluid heaters (M), and returns to the hopper (D) through the recirculation hose (P). Immersion heaters (L) installed through the sides of the hopper help to maintain the temperature of the spray material during recirculation.

XM sprayers are not approved for use in hazardous locations unless the base model, all accessories, all kits, and all wiring meet local, state, and national codes.

Oil or a 50% water and 50% ethylene glycol mixture can be added to the hopper’s outer cavity to a controlled temperature and help maintain the temperature of the spray material. The heated fluid in the outer jacketed area helps prevent heat loss of the spray material.

A 50% mixture of water and ethylene glycol mixture heats up faster than typical hydraulic oil. See F

IG. 2.
