ABSTRACT OF THE DISCLOSURE An ambulant liquid spray apparatus includes a portable liquid storage tank having shoulder carrying straps, a single-action pump for spraying the contents of the tank and a flexible hose communicating one end of the pump with the stored liquid. The pump body defines a cylindrical chamber in which is slidably disposed a rigid tube having a free end with a non-telescoping handle extending outwardly of the chamber for reciprocably displacing the tube within the chamber and a pair of check valves located within the tube and pump body direct a unidirectional flow of liquid through the chamber and tube as the tube is reciprocably displaced. A packing gland nut sealably closes the other end of the chamber intermediate the body and tube, the nut having sidewalls defining an aperture aligned coaxially with the chamber for slidably guiding the tube, seal means inter- mediate the sidewalls and tube, and an annular chamber formed in the sidewalls and defining a lubricant reservoir intermediate the sidewalls, seal means and tube so that a liquid lubricant confined to the reservoir lubricates effectively the portion of the tube slidably guided by the nut.
