The "3-Piece" Configuration

 

This set is famously known as a "3-piece" unit, designed for rapid deployment and ease of use:¹

 

1. The Pump (Cylinder): A double-action piston pump mechanism often encased in durable brass or steel. It builds pressure on both the up and down stroke for a continuous, powerful stream.

2. The Hose (Intake & Discharge): Typically features a long, high-quality rubber hose (approx. 5m) that allows you to move freely around your workspace while the intake stays submerged.

3. The Stand (Stirrup/Foot Base): A fold-out or fixed metal footplate that stabilizes the pump on the ground. You simply step on it to anchor the unit while pumping, allowing for comfortable, ergonomic operation.

Key Features & Benefits

 

• Genuine Swiss Surplus: Authentic military issue (often dated mid-20th century), meaning it was built to last a lifetime.

• Solid Construction: The core pump components and nozzles are machined , resisting corrosion and ensuring smooth mechanical action.

• High-Pressure Output: Capable of generating significant pressure, making it strong enough to jet-wash mud off boots or mist delicate plants depending on the nozzle setting.

• Portability: Lightweight yet sturdy; it packs down easily for storage in a shed, truck, or emergency kit.

• Self-Priming: The weighted intake filter (strainer) sinks to the bottom of any bucket, preventing clogging from debris and ensuring immediate water flow.
