Have turned here for help in locating a product. We design enhanced precision machine tools and have requirement for a continuous flow, lubrication pump. A pump-motor assembly would be preferred. Understand such pumps are available for this application through Bijur and Lube USA, but pricing far exceeds value.
Require a gear pump with approximately 0.07 cc/rev displacement, 40 PSI working pressure, 1700 RPM, with 1/8 NPT ports. This need not be a precision, or medical grade pump.
 
Try the globalspec search engine. I've seen the pumps you speak of, sold/resold/rebranded to a number of different outlets, but would imagine there is really just one or two real manufacturers.

 
With such low pressure operation and the lack of precision you can run a larger pump as a lower speed. The thicker the fluid the better the pump will operate at lower speed. We use a small Delta hydraulic pump to pump a 50 weight oil at a few CC per minute driven with a low input speed.
