Q. How long does the internal electric pump last?
A. Under normal use the BetaGauge 330 internal pump can be expected to last a minimum of 5,000 cycles to full pressure before requiring a rebuild. Since the pump won’t normally always be cycled to full pressure (typically 150 PSI / 10 Bar / 100 kPa), it should realistically last longer.
In addition, our testing to get the 5,000 cycle number consisted of running the pump repeatedly to full pressure with a break of 10 minutes every 10 cycles. This also is not a normal type of use where the calibrator may only be used a few times a day, if that. Again, that relates to even longer lifetimes.
If you assume that the calibrator is used to perform 4 calibrations a day, with each calibration requiring 3 pump cycles just to get everything right, then a pump rebuild might be required after 1 year and 8 months. I based this on 250 working days a year, which I think is typical.
But, if the worst really happens, a pump rebuild is a field procedure. Martel offers a kit with all the necessary parts to replace the wear items in the pump and get it fully functional again. A technician will only need a few simple tools and the ability to unsolder and resolder the power leads to the pump. A rebuild should take less than 1 hour to complete and get your BetaGauge 330 back in business.
Cost of the rebuild kit? About $20.00.
