RW15-SX Left-Hand Shaft Commercial Pump

The Annovi Reverberi RW15-SX is a commercial-duty triplex plunger pump engineered for equipment that requires a left-hand shaft configuration.

Why Choose a Left-Hand Shaft Pump?

Most pressure washer pumps use a right-hand shaft, but many specialized rigs require the opposite orientation. The RW15-SX is engineered to meet this need by offering a true left-hand 24mm shaft with no adapters or custom modifications required.

This makes the RW15-SX ideal for:

• Dual-pump mirrored systems
• Trailer rigs with reverse-mounted engines or tight spacing
• OEM machines designed specifically for left-hand drive
• Compact equipment requiring mirrored pump orientation

Durability and Performance

The RW15-SX is built with premium components to ensure reliable performance in demanding environments:

• Brass Manifold: Precision-machined for strength and pressure stability
• Stainless Steel Valves: Corrosion-resistant and reliable under continuous use
• Ceramic Plungers: Provide superior wear resistance and smooth operation
• Heavy-Duty Seals: Designed to reduce leaks and extend service intervals
• Oversized Bearings: Minimize vibration and increase operational life

Together, these features ensure smooth flow, minimal downtime, and long-term service life.

• Direct left-hand replacement for the TSS1511
• Compact design easy to integrate into tight layouts
• Maintenance-friendly with sight glass and vented dipstick
• Commercial-grade construction for demanding use
• Backed by a 5-year warranty and nationwide service network

Applications
