    摘要： A reciprocating pump, comprising a reciprocating motor having a housing body which includes an open first end and a base at the first end, the base substantially closes the first end of the motor housing. The motor also includes a reciprocating member movable by the motor. The member has an end and is adapted to be movable through a housing body chamber. The reciprocating pump includes a pump outlet having a first end, a second end, a pumped fluid outlet port between the ends, and a passageway joining said ends and adapted to receive the end of the reciprocating member. The passageway has a minimum width and the outlet body is connected to the pump base. The reciprocating pump also includes a pump member adapted to be flow connected to the second end of the outlet body. The pump member has a movable check for displacing the pumped fluid to the outlet, said movable check being operatively connected to said end of said reciprocating member and said check also having a width that is less than the minimum width of the passage so that the check is serviceable with the reciprocating pump in line.

    摘要翻译： 一种往复式泵，包括具有壳体主体的往复运动马达，所述壳体主体包括敞开的第一端和在所述第一端处的基部，所述基座基本上封闭所述马达壳体的所述第一端。 电动机还包括可由电动机移动的往复运动件。 该构件具有端部并且适于可移动通过壳体主体室。 往复泵包括泵出口，其具有第一端，第二端，在端部之间的泵送流体出口端口以及连接所述端部并适于接纳往复运动件的端部的通道。 通道具有最小宽度，出口主体连接到泵底座。 往复泵还包括适于流动连接到出口主体的第二端的泵构件。 泵构件具有用于将泵送的流体移动到出口的移动检查件，所述可移动检查件可操作地连接到所述往复运动构件的所述端部，并且所述支票的宽度小于通道的最小宽度，使得支票 可与往复泵一起使用。
