Claim 11:
12. An orbital pump, comprising:
first and second interleaved parts which are operable to follow an orbital path with respect to each other; and
a safety device comprising:
a first member configured to be fixed with respect to the first interleaved part; and
a second member configured to be fixed with respect to the second interleaved part, the second member defining an aperture into which the first member is configured to be received, the aperture being dimensioned to prevent movement of the first interleaved part with respect to the second interleaved part beyond the orbital path,
wherein the aperture is dimensioned to accommodate movement of the first member without contact when following the orbital path, and
wherein contact between the first member and the second member facilitates transmission of a signal to prevent operation of the orbital pump.
