Installation & Operating Instructions

CAUTION

Read instructions thoroughly before installing the tester. If you have any questions regarding product installation or
maintenance, call the factory for more information.

INSTALLATION

CAUTION

The information in this manual is for general application only. Any guidelines furnished by the manufacturer of the
machine’s hydraulic components should be followed. Specifi c systems may require specifi c test procedures.

Install the portable tester at any location in the hydraulic circuit with the fl ow from “IN” to “OUT” as marked near the ports
of the fl ow meter. It is advisable to keep any elbows, tees, valves, etc. at least 12 inches (31 cm) away from the inlet and
outlet ports to preserve the accuracy of the fl ow measurement. Use quick disconnect couplings for easy connections
and to keep tester sealed and clean when not in use.

Diagrams illustrating Typical Test Placements for the testers are located in the Test Procedures section beginning on
page 10.

OPERATION

WARNING

All testers are shipped with the loading valve in the closed position. The loading valve must be opened fully before
initiating fl ow and testing of the hydraulic circuit. Turn the loading valve handle counterclockwise to the fully open
position. Failure to open the loading valve fully can result in injury to personnel and/or damage to the equipment.

The HFP-110 and HFP-120 Series Testers utilize a 3 position, single toggle switch to turn on the power and to select to
display either fl ow or temperature readings. These models are factory calibrated for either U.S. or metric readings.

Page 8

Figure 2 - Toggle Switch

Portable Hydraulic Testers
Installation & Operating Instructions

The HFP-100 Series Testers can be changed in the fi eld between U.S. and metric readings via a slide switch located in
the center of the front panel. Use a small pointed object to slide this switch to the desired position.

Installation & Operating Instructions

On all models, the battery voltage is affected by cold temperatures. Allow time for the circulating oil to warm the tester
before critical measurements are taken. On the HFP-110 and HFP-120 Series, a LO BAT signal on the display indicates
a low battery condition. On the HFP-100 Series, a fl ashing colon (:) on the display indicates a low battery condition.
Replace the batteries with 4 “AA” alkaline batteries. See Battery Replacement on page 15.

Test Procedures

WARNING

All testers are shipped with the loading valve in the closed position. The loading valve must be opened fully before
initiating fl ow and testing of the hydraulic circuit. Turn the loading valve handle counterclockwise to the fully open
position. Failure to open the loading valve fully can result in injury to personnel and/or damage to the equipment.

CAUTION

The information in this manual is for general application only. Any information furnished by the manufacturer of the
machine’s hydraulic components should be followed. Specifi c systems may require specifi c test procedures.

General Information

The HFP-110 and HFP-120 Series Testers are designed to measure fl ow, pressure and temperature. The HFP-100
Series Testers are also designed to measure power.

The power measurements are derived from the product of fl ow and pressure. When using a HFP-110 or an
HFP-120 Series Tester, power can be calculated using the formulas on page 19.

Standard Test Conditions

Install the tester as described in one of the following test procedures:1.

Pump Testa.
“Tee” Testb.
Control Valve, Cylinder and Hydraulic Motor Testc.
Relief Valves in Separate Housingsd.
Relief Valvese.

Open the loading valve fully by turning the handle counterclockwise.2.

Start the pump and adjust it to rated speed.3.

To raise the system temperature, close the tester loading valve to develop a pressure somewhat below the relief 4.
valve pressure. Maintain until the desired temperature is reached.

Open the tester’s loading valve fully and proceed with the required test procedure.5.

The tester will display fl ow, pressure, temperature and power readings.6.

Page 10

Close the loading valve to increase pressure from zero pressure to rated or maximum pump pressure to 3.
determine pump condition.

The pump fl ow at rated pressure can now be checked against the pump manufacturer’s specifi cations. A 4.
decrease in fl ow from zero pressure to maximum pressure indicates the pump condition. A pump that delivers
a constant low fl ow at zero pressure and at maximum pressure suggests suction problems.

“Tee” Test

A tee must be installed between the pump and control valve and connected to the “IN” port of the PFM tester. The
“OUT” port of the tester is connected to the tank. Pumps and relief valves can be isolated from the system and
checked with the “Tee” Test.

Installation & Operating Instructions

WARNING

Increase pressure slowly. The relief valve may now be isolated from the hydraulic circuit, and system pressures
higher than the relief valve setting can result in injury to personnel and/or damage to the equipment.

Pump Test1.

Plug the line to the control valve.a.

Open the tester loading valve fully to read maximum pump fl ow at zero pressure.b.

Close the loading valve to increase pressure from zero pressure to rated or maximum pump pressure to c.
determine pump condition.

The pump fl ow at rated pressure can now be checked against the pump manufacturer’s specifi cations. d.
A decrease in fl ow from zero pressure to maximum pressure indicates the pump condition. A pump that
delivers a constant low fl ow at zero pressure and at maximum pressure suggests suction problems.

Relief Valve Test (For relief valve in separate housing, see page 13)2.

Put a control valve into a power output mode with the output fl ow blocked, such as a cylinder at the end of a.
its stroke.

Close the tester loading valve while viewing the pressure. Pressure will increase until the relief valve b.
opens. Record the pressure at this point. Repeat to check the relief valve adjustment.

Control Valve, Cylinder and Hydraulic Motor Test

Put one control valve in an operating position. (Only one control valve should be in an operating position at 1.
any one time.)

Slowly close the tester loading valve to achieve the pressure obtained in Step 3 under Pump Test or Step 1.c. 2.
under "Tee" Test and record the fl ow. Repeat for all operating positions of all control valves.

If all components are in good operating condition, pressure and fl ow measurements should be the same as a.
in Step 3 of the Pump Test.

If a decrease in fl ow in any control valve position is noted, leakage is indicated. See Step 3 below for the b.
test routine to determine which control valve is at fault.

If the decrease in fl ow is the same with the control valve(s) in all positions, it indicates that the relief valve c.
is at fault. (Note: This can also indicate some other leak is present in the control valve such as a defective
casting, damaged seals, or worn valve position detents - but always check the relief valve FIRST.)

To locate the fault in the control valve, cylinder or motor, disconnect cylinder and plug connection.3.

Place the control valve handle in the position where greatest decrease of fl ow was noted.a.

Close the tester loading valve to achieve the test pressure and record the fl ow.b.

If the same decrease in fl ow is noted as in test performed in Step 2.b. above, then the control valve is at c.
fault. HOWEVER, if the fl ow readings are now higher and comparable to the other control valves, then a
faulty cylinder or motor is indicated.

Relief Valve in Separate Housing

Install the tester in a "Tee" Test confi guration to the line connecting the pump and relief valve. Plug any extra 1.
outlets.

Close the tester loading valve and watch the pressure and fl ow.2.

Page 12

Portable Hydraulic Testers
Installation & Operating Instructions

Reconnect the control valve to the tee. Put a control valve into a power output mode with the output fl ow a.
blocked, such as a cylinder at the end of its stroke.

Close the tester loading valve while watching the pressure. Pressure will increase until the relief valve b.
opens. Record the pressure at this point. Repeat to check the relief valve adjustment.

Relief Valves

Often relief valves will start to open before they reach their full pressure fl ow settings. This can be noted by comparing
the pressure and fl ow rate readings made in Step 3 under "Tee" Test. Any great decrease in fl ow rate from tests made
in Step 3 under "Tee" Test indicates a faulty relief valve.

MAINTENANCE / TROUBLESHOOTING

The HFP Series Testers are designed to give years of trouble-free service. However, if trouble is suspected, a few

simple checks can be made.

Load Valve

If the valve fails to load the system, remove the valve body and check for foreign material, worn parts or seals.

Flow

The absence of any fl ow reading may indicate a blockage of the turbine. Remove the retaining ring from the inlet port

and carefully remove the turbine assembly. Remove any material that may be preventing easy rotation of the rotor.

Reassemble and attempt a fl ow reading again. If the tester still fails to indicate fl ow, it is recommended to return the

tester to the factory. For return procedures, contact Omega.

Burst Discs and Burst Disc Bodies

The burst discs are designed to rupture at a specifi ed pressure. The testers have a single burst disc that vents externally
when ruptured. If rupture occurs, the burst discs must be replaced.

WARNING

If you do not have the proper tools to accomplish this task, it is highly recommended that you return the tester(s) to the
factory for replacement of the burst disc housing and the burst discs. Injury to personnel and/or damage to equipment
may result if the burst discs are installed improperly.

The following tools and parts will be needed:

• Phillips head screw

• 3/4" open end box wrench

• 0-50 (or greater) pound-inch torque wrench

• Awl

• Burst disc body, P.N. F2138

• Burst disc, P.N. F1614-6000

Page 13

Portable Hydraulic Testers

Installation & Operating Instructions

Burst Disc Replacement Procedure

1. Position the tester block so that the pressure relief plate is accessible as shown in Figure 6.

FIGURE 6 - Burst Disc

2. Remove the four Phillips head screws holding the pressure relief plate from the tester block. Once the plate is
removed, the burst disc body will be exposed.

3. Using the torque wrench, remove the burst disc body from the tester block.

4. With the awl, remove the burst disc from the burst disc body port.

5. Insert the new burst disc into the burst disc body port. Ensure that it is seated fl ush within the base of the well. Be
careful not to scratch the surface of the burst disc.

6. Insert the burst disc body into the burst disc body port and hand tighten into the test block. If required, use a new
burst disc body, P.N. F2138.

7. Set the torque wrench to 25 foot-pounds (37.3 N-m). If using a direct reading torque wrench, go to step 8.

8. Torque the burst disc body into the tester block. Torque to 25 foot-pounds (37.3 N-m).

CAUTION

Do not over torque the burst disc housing. Applying too much torque will damage the burst disc and cause the disc

to rupture prematurely.

Page 14

Portable Hydraulic Testers
Installation & Operating Instructions

Battery Replacement

All testers utilize four AA size alkaline batteries. These batteries will normally provide approximately 50 hours of service
before a low battery condition is indicated. On the HFP110 and HFP 120 Series Testers, a LO BAT signal on the display
indicates a low battery condition. On the HFP-100 Series Tester, a fl ashing colon (:) on the display indicates a low
battery condition. When a low battery condition has been displayed, immediately remove discharged batteries from the
tester to prevent battery holder corrosion.

To change the batteries, remove the 4 screws on the cover assembly. Pull the cover slowly upward to clear the internal
components. The batteries are located on the bottom of the case. See Figure 7. When installing the new batteries,
ensure that they are centered in the holder and making contact at both ends. Replace the cover and secure the 4
screws.
