INTRODUCTION

This manual provides operation and service instructions and a

parts list for the “Manzel” Model HP-50 and HP-60 High Pressure

Lubricators, Discharge and Terminal Check Valves.

The high pressure lubricator comprises one to four 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 INSTRUCTIONS

1. 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 re quired at start

up.

2. 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:

• 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.

• 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.

• 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.

• Readjust the pumping rate to the desired delivery.

3. 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 displace ment 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.

4. 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 (0.017 cc) per pump stroke.

SERVICE INSTRUCTIONS

1. Lubricator operation can be checked by observing the drip

tube. If the correct pumping rate is maintained, no servicing

is required other than periodic replenish ment of the reservoir.

If the sight glass well pumps dry or no flow is observed,

check the following points until the cause is determined and

corrected.

• Check the vent plug for proper sealing. Any nicks or

cracks in the rubber plug will cause an air leak into the

sight glass.

• Check shaft rotation. If the lubricator shaft is not

rotating, determine the cause and repair as necessary.

• Check oil level and viscosity. Be sure the reservoir is

filled with oil, and if necessary heat the reservoir to

maintain viscosity at the correct level for the desired

flow.

• Check pump priming. If necessary, prime the pump in

accordance with the “Operating Instructions”.

• Check the feed adjustment and readjust if the pumping

rate is too low.

• Check the actuating linkage for proper operation. If

defective, isolate the broken part and repair or replace

as required.

2. If none of the above steps isolate the malfunction, the

cause is in the pump assembly. The following items

should be checked before removing the pump assembly

from the cover.

• Check the sight for inward leakage due to a crack in the

sight glass, improper sight glass seating, or a defective

O-ring. Repair as required.

• Check for an obstruction in the drip tube and remove if

found.

3. If the above steps do not isolate the malfunction, disconnect

the discharge tubing and remove the pump assembly which

is attached to the cover with four screws. It is not necessary

to stop the equipment on which the lubricator is installed

or to empty the reservoir. Faulty pumps should be returned

to the fac tory for repair as they contain a selectively fitted

cylinder and plunger. A spare pump should be on hand for

use during emergencies when a pump is being repaired.

4. If the sight glass fills with lubricant proceed as follows:

• Remove the vent plug and allow the lubricant to pump

down to the proper level. Replace the vent plug. The

pump should operate normally.

• If the sight glass continues to fill with lubricant check all

terminal check valves for proper operation. If the valves

are operating properly, remove and clean the pump

assembly, then re install the pump in the system and

check operation.

• If the sight glass still fills with lubricant it may be caused

by temperature variation.

1) When the unit is not operating, remove the vent

plug and allow the lubricant to pump down to the

proper level. Replace the vent plug. The pump

will now function properly. The sight glass may fill

with fluid without affecting the operation of the

lubricator as long as the drip tube remains above

the lubricant level to show the rate of pumping.

2) When the unit is operating, the sight level will vary

depending on temperature variations. If the level

falls to less than 1/4inch above sight glass flange,

add lubricant to the proper level (3/8 inch below the

discharge of the drip tube) through the vent hole.

If the level is too high, remove the vent plug and

allow the unit to pump down before replacing the

vent plug.

5. Other servicing that may be required is listed below:

• Periodic cleaning of the lubricator is desirable to

eliminate contamination that may have occurred in the

oil. To accomplish this, remove all pumping units and

clean the pumps and reservoir by brushing loose all

foreign matter, dipping in solvent and blowing dry with

compressed air.

• If external leakage is observed, determine the cause

(loose bolts, defective gaskets, or seals) and repair as

required.
