Carry out lubrication
It is recommended that the cams of the pump should be cleaned once
a year, using a paper towel or cotton bud to remove any dirt that may
affect the cam life.
Once clean, apply a small amount of the recommended lubricant (see
below) to each cam. Run the pump at a fast rate whilst lubricating to
ensure good coverage of the cam and the follower
DO NOT lubricate the encoder cam wheel.
Recommended lubricant
Graseby Medical recommend that the following lubricant should be
used:
• ‘STP Oil Treatment’, available from most car accessory outlets, and
manufactured by First Brands Europe Limited. Also available from
Graseby Medical, part number 6835 0510
This non-organic product has a good general coating performance,
and has proved to be safe with various plastics.
Check pole clamp screws
With the case open for the lubrication procedure, it is recommended
that the four screws holding the pole clamp in place should be
checked. These screws should be tightened to a torque of
180-190 cNm. This is particularly relevant in areas where the
modular connection system is employed regularly.
Check pump condition
Inspect the pump to check that it is in good condition as follows:
1. The safety information and operating instructions on the side of
the pump must be legible.
2. The mechanical conditions of the pump must allow safe operation.
3. The pump must be clean.
Carry out electrical safety checks
Check that the pump operates within the electrical safety ranges
described here:
1. The safety fuses must be of the specified type and rating.
2. Ground impedance between the protective contact in the AC mains
plug and the potential equalisation terminal must be equal or less
than 0.2 Ohm.
3. Ground impedance between the protective contact in the pump
inlet and the potential equalisation terminal must be equal or less
than 0.1 Ohm.
4. The leakage current meets the specification.
