Introduction

The PV 210 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.

Operation

WARNING: Before applying pressure, make sure all connections are correct and the equipment is internally clean and free from damage. Make sure that all equipment is to the correct pressure rating. Do not exceed the maximum operating pressure stated in the specification. Observe the relevant health and safety precautions.

CAUTION: If PTFE tape is used to seal NPT threads, ensure that only a sufficient amount is used to achieve a pressure seal. If the excess tape is used, particles can become loose during the connector mating process and enter the pump, potentially leading to loss of pump performance or pressure leaks.

INFORMATION: Because the PV 210 only has a small displacement, only use the PV 210 to pressurize small volumes.

Note: Wherever possible, use o-ring seals in the BSP connection ports this is the recommended method of sealing.

Quick-fit connectors.
1 m (3.3 ft) x 3 mm (1/8”) flexible nylon hose (x2).
1/4” female BSP or NPT adaptor.
Pump handle.
Adjustable pressure relief valve.

Hose/Adaptors (Figure A1)
To attach a hose (5) and adapter (6) to a connector (4), turn the knurled nut on the connector counterclockwise.

Pressure Release Valve (Figure A1)
Use this (1) 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 (Figure A1)
INFORMATION 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.

To make accurate adjustments to the pressure, turn the fine adjust vernier (2) clockwise to increase the pressure or counterclockwise to decrease the pressure.

Pressure/Vacuum Selector (Figure A1)
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
(Figure A2) Use this (8) to prevent damage to sensitive instruments. To adjust the maximum output pressure, turn the screw in the bottom of the pump handle.

Operation with a High-Resolution

WARNING: DO NOT ignore the maximum operating pressure specified on the pump label. Before you connect a pressure component to the PV 210, 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.

Calibration/Comparison against an Analog Gauge

Connect a reference instrument with a hose (5)/adaptor (6) to a connector (4).
Use the same procedure to connect the instrument under test to the other connector (4).
Note: The maximum torque for the adaptors is 15 Nm (11 ft lb).
Set the fine adjust vernier (2) to the midpoint of its travel: Turn it fully clockwise, then four to six turns counterclockwise.
Close the pressure release valve (1): Turn it fully clockwise, and tighten to seal.
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.
Operate the pump handle (7) until the pressure is almost correct.
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.
You can also decrease the pressure by careful operation of the pressure release valve (1).
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.

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 7 above.
Note: On very high resolutions such as 1 mbar or 0.1 inH2O, small movement of the hose may result in noticeable pressure changes.

Fault Finding

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 PV 210 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 instructions.

If, for any reason, a fault occurs within the pump, it is recommended that the equipment be returned to an appointed agent.
