A novel method for counting pump cycles of an air pump by detecting the air pressure differential of the air pump cycle with a differential pressure switch and attaching an electronic counter to the pressure switch to count the number of openings and /or closings detected by the pressure switch.

Inline stroke counter for air pumps

A high pressure gas cleaning purge cleaning silicon oxide dust deposits from inside a dry vacuum pump while installed on a crystal grower. The high pressure gas cleaning purge is performed before or after each crystal is grown. The high pressure gas flow is injected into the inlet of the dry vacuum pump and repeatedly turned on and off to create differing turbulent flow patterns within the pump. The differing turbulent flow patterns effectively remove substantial quantities of the silicon oxide dust deposited in the pump during crystal growing.
