Vickers PVQ20 B2RA9 SS1S 20 CM7

This Vickers PVQ series pump is often used in metal forming, metal cutting, and injection molding machines, as well as conveyor lines, primary metals processing, oil and gas equipment, and mining machinery.

Injection molding is actually one of the listed applications for this pump, so it's not a stretch at all. The PVQ20 is built with longer service life and lower operating pressure requirements in mind, which tends to work in your favor on continuous-duty molding setups where you need steady, predictable output without hammering the system. The reduced noise characteristic is a practical bonus in a shop environment too.
