You will need a pressure tank and a regulator for any impact head type (chit chit chi-it-it as you say) sprinklers on an irrigation system to work properly. Set cut in pressure on pump to be above that which a pressure regulator will deliver to the final line - that way pressure will be constant to the sprinkler heads (make sire its above their minimum required pressure) and pressure upstream from the regulator will vary between cut-in and cut-out as moderated by the pressure tank. Depending on the amount of water delivery you intend to have you may want a 20 gallon or larger pressure tank.

Our system has 7 sprinkler heads operating at 55 PSI with a pump and pressure tank set at 60 and 70 psi - water delivery pressure is constant regardless of number of heads open (up to our limit of 7) and the radius of irrigation is the same for each head regardless of how many are on.
