Pump-action

— one of the varieties of sprayers powered by the user's muscular strength — along with lever ones (see the relevant paragraph). The difference lies in the fact that in this case the accumulative principle is used: with the help of a pump, a supply of compressed air is pre-inflated into the tank, which is gradually consumed during operation; the stock needs to be replenished from time to time by pumping up the pump. A characteristic external sign of a pump-action sprayer is the paging handle located in the upper part; Because of this, shoulder-carrying models (see "Design") have to be worn on one shoulder so that the handle remains within reach. This is somewhat less convenient than carrying lever models on two shoulders; on the other hand, one hand remains free when working with this type of shoulder sprayer. And the common advantage of all pump units is that during operation it is not necessary to constantly pump air. On the other hand, this design is not well suited for more or less large volumes, so the tank capacity in this type of atomizers does not exceed 12 liters.
