A trigger pump dispenser comprises a body, an outlet nozzle, a pump chamber, a piston for defining a variable volume in the pump chamber, a trigger coupled with the piston by interconnection means, and biasing means for biasing the trigger to a retracted position. The trigger is movable to cause the piston to pump liquid into and out of the pump chamber for dispensing through the outlet nozzle. The piston is interchangeably associatable with the trigger and the pump chamber so that different length pistons are usable to determine different maximum fill volumes of the pump chamber.

A trigger pump dispenser has a dispensing passage, an outlet nozzle movable between an 'on' position and an 'off' position, and a shroud. First and second indicator tabs project from the outlet nozzle and correspond with first and second indicator windows in the shroud. When the outlet nozzle is in the &#x201c;on&#x201d; position, the first indicator tab resides in the first indicator window and the second indicator tab is hidden by the shroud, and when the outlet nozzle is in the &#x201c;off&#x201d; position, the second indicator tab resides in the second indicator window and the first indicator tab is hidden by the shroud.
