Abstract: A safety device for an orbital pump has first and second interleaved parts which are operable to follow an orbital path with respect to each other, the safety device comprising: a first member fixable with respect to the first interleaved part; and a second member fixable with respect to the second interleaved part, the second member defining an aperture into which the first member is receivable, the aperture being dimensioned to prevent movement of the first interleaved part with respect to the second interleaved part beyond the orbital path. In this way, the members of the safety device help to prevent the moving components of the pump contacting, thereby preventing damage.

Abstract: A sensor assembly for use in an apparatus comprising at least one moving part and at least one stationary part is provided. The assembly comprises a probe and means for mounting the sensor to a stationary part of the apparatus. The probe comprises a portion of an incomplete circuit which, when completed, produces a signal. In use, when the probe is engaged by a moving part of the apparatus, a signal is produced. A vacuum pump or a compressor pump comprising the sensor and a method for preventing failure of an apparatus are also provided.
