Booster pump

[Stephen62]

I installed about 150 ft of 1/2 plastic pipe around the perimeter of the back yard for watering of the lawn and garden area. When the timer turns on there is not enough water for the 3 pop up sprinkler heads and the garden watering to work adequately.

I believe that I require a pump that I would control with a pressure switch and the timer. The system doesn't require too much help but it doesn't have the pressure to cover the area adequately. How do I choose a suitable pump for my requirements?

Thanks.
