DESCRIPTION

This system is a portable source of pressure and vacuum. Each pump includes a pressure/vacuum selector, a volume control for fine adjustment and an adjustable pressure relief valve to prevent damage to sensitive instruments.

Note: Because it has a small displacement, only use the system to pressurize small volumes.

HOSE/ADAPTERS

To attach a hose (5) and adapter (6) to a connector (4), turn the knurled nut on the connector counterclockwise.

PRESSURE RELEASE VALVE (1)

Use this to reduce or release the pressure in the system. The amount of turn sets the rate to release the pressure. Only minimum force is necessary to seal the system.

FINE ADJUST VERNIER (2)

To make accurate adjustments to the pressure, turn the fine adjust vernier clockwise to increase the pressure or counterclockwise to decrease the pressure.

IMPORTANT: To prevent damage, when the top of the pump body comes into view, DO NOT use force to turn the fine adjust vernier (2) farther out.

PRESSURE/VACUUM SELECTOR (3)

Before you change the mode, make sure that the pressure release valve (1) is open. To change the mode, use an applicable tool to push the selector (3) to the side specified on the label.

ADJUSTABLE PRESSURE RELIEF VALVE (8)

Use this to prevent damage to sensitive instruments. To adjust the maximum output pressure, turn the screw in the bottom of the pump handle (Refer to figure).

Operating instructions for the Druck PV210 - Low pressure hand pump

GUIDELINES FOR OPERATION

WARNING

• DO NOT ignore the maximum operating pressure specified on the pump label.

• Before you connect a pressure component to the PV210, make sure that it is isolated from the pressure supply and release the internal pressure slowly. DO NOT connect the pump to an external pressure source.

1. Calibration/Comparison against an analog gauge.

1.1. Connect a reference instrument with a hose (5)/adapter (6) to a connector (4).

1.2. Use the same procedure to connect the instrument under test to the other connector (4).

Note: The maximum torque for the adapters is 11 ft-lb.

1.3. Set the fine adjust vernier (2) to the midpoint of its travel:

Turn it fully clockwise, then four to six turns counterclockwise.

1.4. Close the pressure release valve (1):

Turn it fully clockwise, and tighten to seal.

1.5. To set a maximum output pressure, use a screwdriver to adjust the pressure relief valve (8):

Turn it clockwise to increase the pressure or counterclockwise to decrease the pressure.

1.6. Operate the pump handle (7) until the pressure is almost correct.

1.7. To adjust the pressure to the correct value, turn the fine adjust vernier (2) clockwise to increase the pressure

or counterclockwise to decrease the pressure.

Caution! To prevent damage, when the top of the pump body comes into view,

DO NOT use force to turn the fine adjust vernier (2) farther out.

Note: Initially, small pressure changes can occur (thermodynamic effects, the seals settle, the hoses expand).

The pressure will stabilize after a short time.

1.8. You can also decrease the pressure by careful operation of the pressure release valve (1).

1.9. To get a vacuum, set the pressure/vacuum selector (3) to the vacuum position (as indicated on the pump

label) then use the same procedure as above.

Note: Before you change the mode, release the pressure.

2. Operation with a high-resolution pressure calibrator: Because the resolution is better, it is possible you will see more of the small pressure changes identified in step 1.7

above.

Note: On very high resolutions such as 0.1 in. H change.

FAULT INVESTIGATION/MAINTENANCE

O, only a small movement of the hose is sufficient to see a pressure

• If the system appears to lose pressure, repeat the above procedure. Make sure: there is no damage to the seals,

the adapters are tightened sufficiently, the pressure release valve (1) is tightened sufficiently to seal.

• Do not try to tighten other connections on the pump. These are factory set and changes can cause damage to the

sealed joints.

• During leak tests, small air movements (in or out) are possible around the pressure/vacuum selector (3). This is

normal.

• If the system has not been used for a period of time, it can be difficult to operate on the first stroke. It will become

free after this.

• For seal replacement refer to the service kit IAS-A111-1 instructions.
