Operation
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.
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. During subsequent lubrication cycles, the pressurized line is relieved and
the relief line is pressurized. 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. 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.

Electrical connection to the motor may be necessary depending on the model.
In hydraulically reversed stations, connect discharge lines 1 & 2 using 3/8”
compression fittings. Then, using an appropriately sized screw driver, turn
the air bleed screw 1/4 turn counter-clockwise. After all the trapped air has
escaped, tighten the air bleed screw--turing the screw 1/4 clockwise. Now
wire the limit switch to the proper control. Then, using an appropriately
sized wrench, loosen the nut just below the pressure adjustment. Turn the
pressure adjustment to either raise or lower the pressure. Turning the pressure adjustment clockwise increases the pressure and turning it counterclowise decreases the pressure. After pressure has been adjusted, tighten
the lock nut. See Fig.A. DO NOT ADJUST WHILE SYSTEM IS UNDER
PRESSURE!

In electrically reversed stations, connect discharge lines 1 & 2 using 3/8”

#2
Systems with electrical reversing valves do not rely on system
pressure to alternate between discharge lines directly. Pressure
switches should be purchased separately and wired to the main
control / timer.
PLC or remote operation is required.

Pump Detail / Parts Breakdown
(Part Number: P25-1601-100)
The P25-1601-100 is a twin piston pump.
The motor, coupled to the crank shaft
rotates the eccenter, which in turn, alternatively
moves the pistons in and out of their respective
cylinders. This action draws the lubricant from
the reservoir and pushes it through the the
discharge ports. Back flow of lubricrant is
prevented by way of a check valve assembly
located in front of the cylinder.

!
Do NOT supply electrical power to

on the valve.
!
Do NOT exceed voltage specifications
shown here.
Electrical power should be maintained
on non-detented valves. Detent only
maintains start-up position of the valve.
