Operation 10 3A1334E Operation Thermal Induced Pressure Relief (Oil pumps onl y) Thermal Relief Theory of Operation The pump oper ation is similar to most doub le acting reciprocating pumps . The pump only comes to a com- plete stop on the up st roke .
Operation 3A1334E 11 Install only one pump pe r delivery system. Do not use the pumps in a paralle l pump installation. Loss of pump prime can occur if all the f ollowing e vent s occur in sequence: 1. A ther mal relief e vent occurs . 2. The air supply v alve is closed.
Operation 12 3A1334E Step 6 is for Oil Pumps Only: 6. The thermal relief f eature of this oil pump can increase t he amount of t ime needed to fully prime the pump when compared t o pumps without a ther- mal relief feature. T o m inimize this effect, prime th e pump before connect ing it to an alrea dy primed dis- tribution system.
Operation 3A1334E 13 5. Examine f ollow plate to mak e sure r ubber gr ommet (c) is in place in center of the plate (F IG . 7). 6. Set follow plate on top of fres h grease (F IG . 8). Remov e air by pushing on the f ollow plate until the grease lev el is flush with the opening in the middle of the f ollow plate ( d).
