An air-operated piston pump for lube oil, running at a 3.5:1 compression ratio. Where an electric pump struggles with viscosity, a ratio pump uses shop air to multiply pressure — which is why this is the standard fitment in workshops running oil to multiple service points.
The engineering that matters here is the noise. A pneumatic exchanger and three-stage air discharge system, combined with no colliding mechanical parts, brings operation down to 77 dB. Anyone who has worked next to a cheap air pump all day will understand why that is worth paying for. The true double-acting design also means better performance on less air.
This is the stub version, with a short suction tube for drum mounting. A threaded ring nut secures it to the drum or a wall bracket, and optional extensions are available if you need to reach deeper.
