Onga Dominator Series 4" Submersible Automatic Pressure Pumps with Press Control

The Onga Dominator Series is a premium range of multistage submersible domestic pressure pumps designed for quiet, efficient, and reliable performance. Installed submerged in a tank or well, these units operate completely silently while delivering high flow and strong pressure. Built with the same precision-moulded internals as the renowned Sta-Rite Signature 2000 submersible borehole pumps, the Dominator series offers outstanding durability and efficiency. When paired with an electronic Presscontrol, they provide a fully automatic pressure system with loss-of-prime protection, ideal for a variety of household and irrigation applications.
