Description

The Comet FWS2-4530 S is a heavy-duty, solid-shaft triplex pump designed for industrial and commercial cleaning. Operating at a low speed of 1750 RPM, it is built for long-term durability and is typically found in belt-drive or coupler-drive systems where high flow and high pressure are required simultaneously.

Technical Specifications

Key Features

• Slow-Speed Industrial Performance: The 1750 RPM rating (common for 4-pole electric motors or geared gas engines) reduces heat buildup and mechanical vibration. This makes the FWS2 series much quieter and more reliable for all-day use than 3400 RPM models.

• FWS2 “New Generation” Crankcase: Features a reinforced die-cast aluminum alloy body with an enlarged oil sump. This improves thermal dissipation, keeping the internal bearings cool during extended run times.

• 18mm Solid Ceramic Plungers: Precision-ground ceramic pistons are highly resistant to the abrasive minerals found in water. They provide a smooth surface for the seals, significantly reducing friction and wear.

• Forged Brass Manifold: The high-strength head is designed to resist the internal fatigue and “water hammer” effects of 3000 PSI operation.

• Stainless Steel Check Valves: High-efficiency valves ensure consistent flow and prevent pressure loss, even when using chemicals or hot water.

Ideal Applications

• Commercial Mobile Wash Skids: The 4.5 GPM flow rate is the “sweet spot” for professional cleaners, providing enough water volume to move heavy mud while maintaining high stripping pressure.

• Electric Motor Units: Pairs perfectly with a 10 HP electric motor for stationary indoor wash bays (manufacturing plants, food processing, etc.).

• Belt-Drive Pressure Washers: Ideal for gasoline-powered trailers where the engine and pump are mounted side-by-side to save space and reduce heat transfer from the engine.
