Which item is NOT part of the pump unit assembly of a handheld sprayer?

• A. Nozzle
• B. Tank Cap
• C. Gasket
• D. Handle

Answer: (A)

The pump unit is the pressurizing part of the sprayer: the handle and piston action that moves liquid, along with seals (gaskets) and the cap that keep the reservoir sealed and capable of building pressure. The nozzle sits at the discharge end of the system and shapes or directs the spray after the liquid has been pressurized. Since the pump’s role is to create pressure and control the flow from inside the tank to the outlet, the nozzle is not part of the pump mechanism itself. So the item not part of the pump unit is the nozzle.
