A non-round pressure sprayer unit for dispensing liquids from a closed container including a pressure pump, tube/hose connection, and applicator wand. The pressure pump mechanism further includes a pump housing sealingly insertable in the pressure sprayer bottle, a plunger for reciprocating within the housing with an upstroke and a downstroke, and a pump piston at the lower end of the plunger. The pump piston includes a bottom closure for closing the lower end of the pump housing when the piston is lowered on the downstroke and capable of opening the lower end of the pump housing when the piston is raised in the upstroke. A pump seal seals the piston and the inner wall of the pump housing when the piston is on its downstroke but becomes unsealed on the upstroke of the piston.
