An applicator by which small, discrete, uniform quantities of molten thermoplastic adhesive can be dispensed in rapid succession comprises a body having a heated inlet chamber, which hot melt enters under low pressure, and a pump chamber. A plunger in the pump chamber is reciprocated by a pneumatic motor. A charging stroke of the plunger draws hot melt out of the inlet chamber, across a check valve and into the pump chamber. The discharging stroke expels the hot melt across an outlet check valve and through an outlet orifice coaxial with the pump chamber.
