TIGERFLOW Ocelot 25 Variable Speed Booster Pump, 70 PSI Max Boost - 24 GPM Max / 1 HP - 120V 1Ph / Ocelot 25

The Ocelot 25 is a self-priming, variable speed booster pump with a permanent magnet motor and an integrated drive. It holds an adjustable pressure set point from an easy-to-use interface, and its low-flow detection slows or stops the pump when demand drops. The AISI 304 stainless steel pump body, built-in expansion tank for leak loads and built-in check valves on suction and discharge make it a compact unit for residential and light commercial boosting.

• Permanent magnet motor with integrated VFD
• Adjustable pressure set point through an easy-to-use interface
• Standard self-priming of 9 ft, up to 25 ft depending on installation conditions
• Built-in expansion tank and check valves on suction and discharge
• TEFC motor; IPX-6 cover, outdoor rated ; 120 VAC 3-prong cable connection

The Ocelot 25 runs as one self-contained pump. Size it to the full peak demand now; for a building that needs a standby pump or up to 144 GPM, the Ocelot Duplex runs two Ocelot 60 pumps lead-lag.

Pressure the pump adds, in PSI, at the two points TIGERFLOW prints. The first column is the most it can add.

Ocelot 25 · pressure added in PSI

Drawing from a tank or cistern — nothing arrives with pressure, so what the pump adds is what you get: 39 PSI at 13 GPM.

Fed by a city main — the pump adds on top of what already arrives, and the drive slows it to hold your set point. With 40 PSI arriving and a 60 PSI set point it only has to add 20 PSI, well under the 39 PSI it adds at its 13 GPM rating, so it delivers more than its rated flow. Incoming pressure turns into extra flow at the same set point.

From the performance table in the TIGERFLOW Ocelot Simplex and Duplex booster brochure (April 2025): max head 164 ft, rated 13 GPM at 92 ft, max flow 24 GPM; TIGERFLOW prints no head figure at the maximum flow, so the table stops at the rated point. Zero flow is the shut-off point — a ceiling, not a working point. Figures are at full speed; the drive holds lower pressures by running slower. Feet of head = PSI × 2.31. The brochure’s chart is drawn schematically and is not used for the table.

Best operating range: TIGERFLOW prints no efficiency curve; the rated point is 13 GPM. Ask for more flow than it can deliver at your setting and it runs at full speed continuously, which is where motors and seals wear out. Sizing a booster to the building rather than to the headline numbers is what makes it last.
