What Ships and What It Needs to Run
Included: the pump with its NEMA JM 3,500 RPM motor, brass impeller and a suction flange with flapper valve to hold the prime. The pump body is tapped for an air volume control.
Suction and discharge piping, and an air volume control where a pressure tank is used: sized to your installation and ordered separately.
Overview
Baker built the 84000 to be one of the fastest priming pumps on the market. It is a 3 or 5 HP self-priming centrifugal pump for lawn sprinkling and irrigation, delivering 87 to 146 GPM at 40 PSI from 5 ft of suction lift. The suction flange carries a flapper valve that holds the prime between runs.
For irrigation and other non-potable water. A.Y. McDonald rates the 84000 for non-potable use only; for drinking water, see the NSF-certified A.Y. McDonald jet pumps.

Reading it: a sprinkler zone needing 40 PSI with the water 10 ft below the pump gets 82 GPM from the 3 HP and 141 GPM from the 5 HP. Every extra 5 ft of lift costs flow, most of all at the top of the table.
Zero flow is the shut-off point — a ceiling, not a working point. The curve runs to 132 GPM on the 84300 and 173 GPM on the 84500. Curve figures are digitized from the published curve in the Pumps by Baker catalog, rev 3/26, p. 282, and rounded down; the GPM table is A.Y. McDonald’s printed Performance Data, same page.
Before You Buy — The Limits That Decide the Fit
