ISO 16330:2003规定了往复式容积泵和泵组的技术要求（安全和试验除外）。它适用于利用曲轴和凸轮轴产生的往复运动的泵，以及直接作用的流体驱动泵。它不适用于往复式容积泵，也不适用于泵送水，因为整个泵都用泵送的液体进行润滑。

ISO 16330:2003 specifies the technical requirements, other than safety and testing, for reciprocating positive displacement pumps and pump units. It applies to pumps which utilize reciprocating motion derived from crankshafts and camshafts and also direct-acting fluid driven pumps. It does not apply to reciprocating positive displacement pumps, nor pumping water, where the whole pump is lubricated with the liquid being pumped.
