Model HP-15 High Pressure Lubricators

DESCRIPTION

The high pressure lubricator comprises one to six
integral sight and pump assemblies in a cast iron
reservoir. The unit is designed for direct connection to an
electric motor/speed reducer power source. A “Manzel”
terminal check valve is recommended in the lubrication
system. When required to maintain proper oil viscosity,
the reservoir can be fitted with an optional steam or
electric heater.

OPERATING

Oil Level —

When necessary, completely fill the lubricator reservoir
with clean filtered lubricant. Three sight glasses, pro­vided in the reservoir at various levels, permit observation
of fluid level. Oil level should not be allowed to drop
below the bottom sight glass. During the initial filling, the
vent plugs at the top of the pump sight glasses should
be removed. This allows lubricant to rise in the drip tube
up to the level of the oil in the reservoir and reduces the
priming required at start up.

Pump Priming —

If the sight well on the pump does not contain oil, the
pump should be primed. Pumps may be primed while
the lubricator shaft is rotating as follows:

a. Adjust the pumping rate to the maximum setting by

turning the adjustment nut on the indicator stem as
far as possible in a clockwise direction.

b. Remove the vent plug on top of the sight glass and fill

the housing sight well with oil to 3/8 inch below the
discharge of the drip tube.

c. Replace the vent plug. Check the sight glass to insure

that it is properly seated against the O-ring to prevent
air leakage into the sight well.

d. Readjust the pumping rate to the desired delivery.

Pumping Rate —
The pumping rate is indicated at the drip tube inside the

sight glass. During the pump suction stroke, fluid is
drawn into the pump from the sight well. This creates a
partial vacuum in the sight well, permitting atmospheric
pressure in the lubricator reservoir to force an amount of
oil equal to the pump displacement through the drip tube
into the sight well. The rate is adjustable for each pump
assembly by means of the pump regulator which varies
the stroke of the positive displacement, reciprocating
pump assembly.

Caution —
The drip tube flow rate is accurate after the pump has

operated long enough to stabilize the pressure inside the
sight well. There is a time lag at start-up, low pumping
rates, and during pump rate changes. Allow sufficient
time to insure an accurate rate indication.

Regulating Pump Rate —
The pumping rate can be varied infinitely within the range

of minimum to maximum by means of the graduated
pump regulators which project through the reservoir
cover. The regulators are easily adjusted by hand during
the pump suction stroke. Maximum pumping rate is
achieved when the adjustment nut on the sight indicator
stem is turned in a clockwise direction as far as it can
go. In this position the sight indicator stem projects the
maximum distance indicating maximum pumping stroke.
When the adjusting nut is turned in a counter-clockwise
direction, delivery reduces, because of a reduction in
pump stroke, until minimum delivery is obtained.

Note —
To retain the hydraulic seal between the plunger and the

cylinder walls, minimum delivery must not go below 1/2
drop, .001in

(0.017 cc) per pump stroke.
