Hi Jon,
I've personally always preferred and used centrifugal pumps. They are reliable, durable, and with minimal staff training (don't run the pump dry basically) are 'turn-key'. If you want perhaps more versatility (higher pressures for spraying trees or something) a diaphragm pump might be the way to go. I don't have much experience with diaphragm pumps, but I would imagine just like irrigation diaphragms a pinhole leak could be a real pain.
