WARNINGS

Read the instruction manual carefully prior to setting up and using the

vacuum calibration pump.

Only personnel with good experience and knowledge of pressure me-

dia are allowed to work with the vacuum calibration pump. Incorrect

use may result in damage to the pump, the instrument connected to

the pump and/or personal injury.

Ensure that all connections are made correctly and that the hose and

the connectors are intact. Do not use faulty hoses or connectors.

Do not connect the pump to a pressure source.

Use only the measuring hose provided by Beamex.

Use only the connectors provided with the pump. Impurities from

wrong materials may plug the pump.

Note.

Decreasing the pressure lowers the temperature of the air in the

measurement system. The faster you pump the more significant the

decrease in temperature. When you stop pumping, the air in the

measurement system slowly warms up again. This results in unwanted

pressure change.

We recommend that the pumping is done with moderate speed to allow the

temperature changes time to stabilize. When required pressure is reached,

wait a while to see if there are any alterations in pressure due to

temperature changes. Wait time depends on the temperature increase and

the measurement system. Then adjust the pressure to required level.

4.1.3 Release Valve Seal

Remove the release valve shaft from the PGV body by rotating the release

valve counterclockwise.

Fit new piston seal (o-ring). Reassemble.

Release valve seal Main piston seal

Fine control seal

NOTE! Using PGVwith seals not supplied by Beamex is at your own

risk. The warranty is no longer valid when using other seals

than the ones supplied by Beamex.

Opening the check valve assembly voids the warranty.

4 TROUBLESHOOTING/MAINTENANCE

If the pump assembly fails to indicate vacuum after considerable pumping

action of the handle, the following items should be examined:

•Check to assure that the connections between the pump, the hose end

and the attached instrument(s) are tight and repeat items 3 and 4 in

chapter 3. Operation. Check to assure that all the unused connectors in

the measuring system are properly plugged.

If a vacuum still cannot be obtained, it’s possible that one or more of the

seals in the vacuum calibration pump is leaking and needs to be replaced.

4.1 Seal Replacement

Depending on the frequency of use, the Main Piston Seal (and others) will

eventually need replacing. Although the replacement seals are an optional

accessory, the same instructions for fitting the seals are included in this

manual as in the replacement package.

Do not scratch the cylinder surfaces when opening PGV.

4.1.1 Main Piston Seal

Unscrew the conical end of PGV. If necessary, use the opening tool

provided.

Pull out the main piston and remove the old piston seal. Fit the new piston

seal. Reassemble.

4.1.2 Fine Control Seal

Unscrew the flat end of PGV by hand. No tools are required.

Pull out the fine control piston and remove the old piston seal. Be careful

not to loose the piston, because it is not fixed to the piston rod. Fit new

piston seal (o-ring).

Lightly grease the piston seal using silicone grease. Reassemble.

2 DESCRIPTION

The PGV vacuum calibration pump is designed to manually generate up to

-0.95 bar (-13.7 psi) of vacuum pressure for quick and accurate calibration

of vacuum pressure instruments.

2.1 Standard Accessories

The standard accessories are as follows:

∗Service seal kit for PGV.

∗Opening tool.

∗R 1/8” 60°female to 1/4” NPT male for connecting the pressure

measurement hose to the instrument to be calibrated.

∗A pressure hose. Length 75 cm/ 2' 5½" with R 1/8” 60°male connector

at both ends.

∗Warranty card.

∗This instruction manual.

2.2 Optional Accessories

The optional accessories are as follows: Order Code

∗Service seal kit for PGV. 8003440

∗A pressure tubing set. 8009435

3 OPERATION

READ THE WARNINGS PRESENTED IN THIS MANUAL BEFORE

OPERATING THE VACUUM CALIBRATION PUMP.

1. Connect the instrument to be tested to the pressure measurement hose

and attach it to the pump. Be sure that all connectors in the measuring

system are connected to an instrument or properly plugged to avoid

leakage.

2. In normal use: Adjust the fine control to mid-travel.

When aiming for the highest possible vacuum: First minimize the

volume by turning the fine control fully clockwise. When the Main piston

no longer increases the vacuum, turn the fine control fully

counterclockwise.

3. Ensure the pressure release valve is closed (turn fully clockwise).

4. Create a vacuum by operating the main piston handle. Adjust pressure

to required value using the fine control.

5. To release the vacuum open the release valve slightly.

The release valve need not be opened fully in order to release the

vacuum. The release valve shaft will loosen from the PGV body if the

valve is rotated too much.

NOTE: Careful use of the release valve and fine control enables a

controlled release of pressure, essential for calibration purposes.
