<p> The Grizzly pumping station consists of a twin piston pump, 20:1 gear reducer, 50lbs. steel reservoir with follower plate and indicator stem, reversing valve, and 1/3 h.p. motor in a NEMA 56 TEFC frame.<span style="line-height:1.5;">The standard system begins when power is applied to the motor which, in turn, activates the pump. In a dual line system, one line is pressurized by the pump while the second line relieves lubricant back to the reservoir.&nbsp; During subsequent lubrication cycles, the pressurized line is relieved and the relief line is pressurized.&nbsp; This alternate action is controlled by the reversing valve. The reversing valve, via a switch, sends the cycle information to the control (if applicable) which can be used to set the cycle time.&nbsp; And it is the time set for the lubrication cycle, together with the measuring valve settings that will determine the amount of lubricant that goes to each bearing.</span> </p>
