Our Rotherham Pump replica is a non-functional look-alike of the wind-driven pumps used to pressurize the fuel systems of many WW1 aircraft. While it does not actually provide any pressurization, it certainly looks the part, with accurate dimensions and a free-spinning propeller! We also plan to offer mounting brackets in the future.
 
Features:
"Castings" (Pump Body, Cylinder Heads) are made from laser-sintered PA12 Nylon, the same material used in many firearm frames and even automotive parts such as intake manifolds. It's tough stuff!
Cylinders are made from real brass and aluminum tube stock.
Oil reminder placards are cast brass with raised text
Propeller shaft is stainless steel, and rides on a sealed ball bearing at one end, and an Olite (bronze) bearing at the other
The propellers are hand carved from solid hardwood. They are finished off with a coat of spar polyurethane for weather and UV resistance. All propellers are carefully balanced on a magnetic balancer to minimize vibration
Propellers are secured to shaft with a pinned castle-nut for retention and safety
3D printed parts are finished off in appropriately colored paint to mimic cast aluminum and brass, and a UV-resistant clear coat is applied for longevity of the finish
Weight of each unit is approximately 1.0lb (455g)
