The Tri-Lube pump is a rugged, single or multiple-piston pump, driven by an electric motor. It is designed for use with Trabon Series Progressive Divider Valves, or may be connected directly to up to three individual lube points. Application is for all types of machinery using grease up through NLGI #2. The pump allows for mounting of one to three individual pumping elements, each having a fixed or adjustable output volume. (The standard version is provided with one pump element installed.) For applications where larger output volumes are required, the individual outputs from two or three pumping elements may be combined to a single output point. Each pumping element includes a pressure relief valve to protect the system against possible overpressure. Options include AC or DC electric motor, and two sizes of grease reservoirs (as listed in Specifications).
