Mini Steam Engine Boiler Hand Feed Pump with 7mm Piston for Model Boilers
Hero Section: Master the Art of Live Steam
There is a distinct difference between a static display and a living, breathing steam engine. The key to that difference is continuity. The Mini Steam Engine Boiler Hand Feed Pump is the essential tool that elevates your setup from a toy to a professional mechanical system. It allows you to extend your run times indefinitely by feeding water into the boiler while it is still under pressure. No more waiting for the boiler to cool down to refill; just pump, maintain pressure, and keep the steam rising.
Why Choose This Hand Feed Pump?
- Uninterrupted Operation: The primary function of this pump is to overcome boiler pressure. It allows you to replenish the water level while the engine is running ("under service"), significantly extending your playtime and enjoyment.
- Industrial Grade Materials: Crafted from high-quality brass with a stainless steel piston, this pump is built to resist corrosion and wear. It isn't just a tool; it’s a durable accessory that matches the aesthetic of your vintage steam collection.
- Dual-Purpose Utility: Beyond refilling, this pump is a critical safety tool. It is perfect for performing hydrostatic testing (hydro-testing) on your homemade or vintage boilers to ensure they can safely hold pressure before firing them up.
- Compact Precision: With a footprint of just 54x14mm, it fits easily onto small baseboards without overcrowding your engine layout, yet the 95mm height provides enough leverage for smooth manual operation.
Technical Highlights: Inside the Mechanics
- High-Pressure Capability: The pump features a precision-machined 7mm stainless steel piston paired with an 8mm stroke. This ratio is engineered to provide enough force to push water into a pressurized vessel without requiring excessive manual effort.
- Reliable Check Valves: At the heart of the pump are stainless steel ball valves. These non-return valves are essential for preventing back-pressure from the boiler, ensuring water only flows one way—into the tank.
- Standard Fitment: Equipped with a 3mm brass joint, it is compatible with standard copper piping used in most model steam applications, making integration into your existing system straightforward.

Usage Scenario: The Sunday Steam-Up
You are running your favorite beam engine. The flywheel is spinning rhythmically, but you notice the water gauge glass on the boiler is dropping low. Instead of the buzzkill of shutting off the burner and waiting 20 minutes for it to depressurize, you simply reach for the Hand Feed Pump. A few smooth strokes of the lever, and you watch the water level rise back to the safe zone. The engine never misses a beat. This is the satisfaction of true steam engineering.
Important Tips from the Workshop
- Plumbing Advice: When connecting the 3mm joint to your boiler, ensure you use a proper union nut and nipple. A small amount of thread sealant or Teflon tape is recommended to prevent air leaks, which can hinder the pump's priming ability.
- Maintenance: If the pump fails to move water, it is usually due to a stuck ball valve (often caused by dried mineral deposits). A simple cleaning of the valve seat will restore performance.
- Safety Check: When using this for hydro-testing a new boiler, always fill the boiler completely with water first to remove all air pockets before pressurizing.
