There is no certain amount of pumps in particular for your B&G sprayer. The amount of pressure will depend on where you are treating and how full the sprayer is. If your sprayer is full all the way to the top, that does not leave much room for air and you could probably only physically pump it two times. If your sprayers was half way full you would need to pump it several times…5-8 times to fill the large space with air to force the product out. Really you just need to pump the sprayer until you feel tension on the pump handle and it becomes difficult to pump any longer. The B&G sprayer is the best sprayer available and it can handle a high amount of pressure.
