Introduction
The PV 211 is a portable source of pressure and vacuum. Each pump includes a pressure/vacuum selector, a volume control for fine adjustment and an adjustable stroke to give overpressure protection.
Operation
WARNING Before applying pressure, make sure all connections are correct
and 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 pressure seal. If 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 211 only has a small displacement, only use the
PV 211 to pressurize small volumes.
Note: Wherever possible, use o-ring seals in the BSP connection ports
this is the recommended method of sealing.
Key to Figure A1
- Pressure release valve.
- Fine adjust vernier.
- Pressure/Vacuum selector.
- Quick-fit connectors.
- 1 m (3.3 ft) x 3 mm (1/8”) flexible nylon hose (x2).
- 1/4” female BSP or NPT adaptor.
- Scissor handles.
- Overpressure protection: Adjustable stroke control to adjust the maximum pressure output per stroke.
- Pressure port: 1/4” BSP or NPT female adaptor for connection to a reference instrument, e.g. digital/analog gauges.
- Seal.
2.1 Hose/Adaptors (Figure A1)
To attach a hose (5) and adapter (6) to a connector (4), turn the knurled nut
on the connector counterclockwise.
2.2 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.
2.3 Fine Adjust Vernier (Figure A1)
INFORMATION To prevent damage, DO NOT use force to turn the fine adjust
vernier (2) farther than the red line indicator on the thread. See item 11 in
Figure A2.
To make accurate adjustments to the pressure, turn the fine adjust vernier (2)
clockwise to increase the pressure or counterclockwise to decrease the
pressure.
2.4 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.
2.5 Overpressure Protection (Figure A1)
To adjust the maximum output pressure of the system, turn the nuts (8) to
increase or decrease the stroke length.
Operation
WARNING Uncontrolled release of high pressure is dangerous and may cause
damage to equipment. Because the internal pressure can get very high during
operation, make sure that all the connections are made correctly.
DO NOT ignore the maximum operating pressure specified on the pump label.
Before you connect a pressure component to the PV 211, 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.
3.1 Calibration/Comparison against an Analog Gauge
-
Connect a reference instrument to the pressure port at the top of the pump (9).
-
Connect the instrument under test to the connection at the end of the flexible hose (5).
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. -
Operate the scissor handles (7) until the pressure is almost correct. To get the maximum pressure output, squeeze the handles fully together on each stroke.
-
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.
INFORMATION To prevent damage, DO NOT use force to turn the fine adjust vernier (2) farther than the red line indicator on the thread. See item 11 in Figure A2.
Note: Initially, small pressure changes can occur (thermodynamic effects, the seals settle, the hoses expand). The pressure will stabilize after a short time. -
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.
3.2 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 6 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 the connections between the pump and the fine adjust vernier (2) or between the pump and the quick-fit connectors (4). 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 211 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.
