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.
