A Faithful Recreation of a Foundational
Component, Reborn with Modern Precision.
As the foundation of the entire cross head pump assembly on early M. Rumely single-cylinder engines, these parts were highly susceptible to frost damage and mechanical stress. That's why we've gone to extraordinary lengths to create a reproduction that isn't just a replacement—it's an upgrade in strength and material.
The process began by taking a flawless original pump suction and capturing its every detail using high-precision 3D scanning. This digital blueprint was then used to 3D print a perfect master pattern for creating a new sand-casting mold. The result is a faithful recreation that captures the exact form, fit, and port alignments of the factory original.
Instead of standard cast iron, we chose to cast this essential part in high-strength Ductile Iron. This modern material offers significantly greater strength and ductility (resistance to cracking) than the original gray iron. This provides a crucial advantage against frost damage and enhances its durability to withstand the operational vibrations of the engine.
Sold as an Unmachined Casting
To provide maximum flexibility for restorers, this part is sold as a high-quality, raw ductile iron casting. It is designed for final machining by you or your machinist. The critical areas that require finishing are:
• The mounting bolt holes
• The water inlet threads
• The suction check valve seat
This approach allows you to precisely match the holes, threads, and seat profile to your specific pump components, whether they are original or other reproduction parts.
Custom Machining Available
Don't have the machining capabilities? We can help. For an additional cost, we can perform the final machining to fit your specific application. Please contact us with the specifications of your check valve and inlet fittings to receive a quote for this service.
Features & Benefits:
• Precision Reproduction: 3D scanned from a perfect original and cast from a 3D-printed pattern to ensure an exact, factory-spec external form.
• Upgraded Ductile Iron: Cast in high-strength ductile iron, offering superior durability and resistance to cracking from frost and vibration.
• Ready for Final Machining: Sold as a raw casting, allowing for custom finishing of the mounting bolt holes, water inlet threads, and check valve seat to match your specific parts.
• Critical Pump Foundation: Serves as the mounting base for the cross head pump assembly and contains the primary suction hook-up for the feedwater line.
• Authentic Form: Faithfully recreated to match the specific design used on early M. Rumely single-cylinder engines from 1890 to 1907.
Fitment Note:
This Cross Head Pump Suction is designed for use on early M. Rumely single-cylinder engine cross-head pumps manufactured from approximately 1890 to 1907. As is best practice, we strongly advise you to compare the part to your pump body and engine mounting points to guarantee a match.
