RW15 | 4 GPM 1450 PSI Pump 1450 RPM 24mm Shaft Replaces TSS1511

RW15 | 4 GPM 3500 PSI Triplex Pump, 1450 RPM, 24 mm Solid Shaft, Replaces TSS1511

The RW15 is an Annovi Reverberi triplex plunger pump rated 4.0 GPM at 3,500 PSI at 1450 RPM, built as a drop-in replacement for the General Pump TSS1511. It matches the TSS1511’s flow, pressure, speed and 24 mm solid shaft, so it goes back on the same belt drive without re-engineering the machine.

For a shop rebuilding a TSS1511 machine, that means a commercial AR pump with ceramic plungers and a heavy RW frame, at 1450 RPM where seals and bearings run cool on long shifts.

What’s in the Box

• RW15 pump with 24 mm keyed solid shaft
• Crankcase oil, pre-filled at the factory
• Vented dipstick. The pump ships with a shipping plug in the oil port. Swap in the dipstick before the first start.
• Operation manual and parts schematic
• 5-year Annovi Reverberi warranty

Will It Fit My Machine?

• Replacing a TSS1511: same flow, pressure, speed and shaft size. Compare mounting holes and port locations against your old pump before installing.
• Drive: belt drive. Size the pulleys so the pump turns no faster than 1450 RPM.
• Electric motor: 10 HP.
• Gas engine: 389cc to 420cc (13 HP class and up).
• Shaft side: for a left-hand shaft, order the RW15-SX.

Not sure? Text a pump specialist at (505) 226-6061 with a photo of your old pump tag and we’ll confirm the swap.

What Else You’ll Need

The pump is sold bare. The unloader, thermal relief valve, inlet filter and rail kit are sold separately:

• Unloader valves: choose one rated for at least 3,500 PSI and 4 GPM. The VR54-200 package is a matched fit.
• Thermal relief valves, inlet filters and rail kits: the AR2748 rail kit mounts the pump to a base for belt drive.
