Description
Sawatec SP-177 Diaphragm Dosing Pump 0.1–12ml CD-R DVD-R Lacquer Photo-Resist
The Sawatec SP-177 is a patented diaphragm-type dosing pump designed for precision fluid dispensing in optical disc manufacturing processes. It delivers highly repeatable micro-doses of process fluids — including solvents, protective lacquers, and photo-resist — with a minimum dose precision of 0.1 ml. The compact puck-style body is constructed from anodized aluminum and stainless steel, making it compatible with a range of process chemicals.

Applications
The SP-177 was developed specifically for the optical disc manufacturing industry, where precise, repeatable fluid delivery is critical. It is used in disc coating lines to apply protective lacquer to CD-R and DVD-R substrates, and for solvent-based edge cleaning to remove excess photo-resist or lacquer from the disc rim before curing. Diaphragm pumps of this type are well-suited for these applications because they handle chemically aggressive solvents without contaminating the fluid path and deliver consistent shot volumes even at low flow rates. Sawatec is a Swiss manufacturer specializing in disc production equipment, and the SP-177 was a common component in mid- to high-volume CD-R and DVD-R production lines from the late 1990s through the 2000s. Surplus units are sought by facilities maintaining legacy disc production equipment, as well as by labs and small-volume producers who need a reliable micro-dosing pump for solvent or lacquer dispensing tasks.
This used Sawatec SP-177 diaphragm dosing pump has been inspected and is in good used condition. It was pulled from a working disc manufacturing environment where it was in active use and functional. The blue anodized aluminum cap shows light scuffing and surface wear consistent with normal service use. The stainless steel body and outlet fittings show chemical residue and some grime buildup typical of a pump used with solvents or lacquers — visible especially around the compression fittings.
