WIWA Professional GX 63:1 airless spray pump, single-leg RS/F chassis

WIWA Professional GX 63:1 pneumatically driven airless piston pump for high-viscosity two-component and single-component protective coatings. Single-leg RS/F chassis variant (P/N 0664095S — S suffix denotes the RS/F single-leg / drum-stinger configuration). WIWA (Wilhelm Wagner GmbH, Lahnau, Germany) — global manufacturer of airless and plural-component spray equipment for the protective coatings industry. The Professional GX 63:1 sits in the WIWA Professional GX airless series alongside 20:1, 30:1, 40:1 and 72:1 ratio pumps; higher ratio = higher fluid pressure per unit of air pressure. Verified spec: pressure ratio 63:1; max fluid working pressure 441 bar (6,396 psi); max air-inlet pressure 7 bar (102 psi); output 153 cc / 5.1 fl.oz per double stroke; all-metal GX air motor with de-icing air distribution designed for continuous duty; wetted set is stainless / rust- and acid-resistant. Chassis variant decoder for the 63:1 pump family: 0664095 = RS/F single-leg stand with drum stinger for direct pickup from 25-200 L containers (this product's base code); 0664099 = RS/W wall-mount chassis; 0664103 = RS/H lift-truck chassis. The trailing S on 0664095S denotes an options suffix (likely stainless-steel wetted set or long stand pipe — treat as single-leg RS/F variant; confirm suffix meaning with WIWA order-code sheet or the specific quotation). Applications: protective marine and offshore coatings (ballast tank, cargo hold, deck), structural steel corrosion protection, high-solids epoxies, zinc-rich primers, tank linings, wind-blade coatings, bridge and infrastructure repaint. The single-leg RS/F chassis is preferred for shop-floor and site work where the pump is fed from a 200 L drum or 25 L pail via the drum stinger — simpler than the wall or lift-truck chassis variants for line-side spray booth work. For plural-component (two-part) mechanical proportioning at similar pressure ratio, see the WIWA DUOMIX PFP series (fixed-ratio) or the Graco XM70 (variable ratio 1:1 to 10:1); the Professional GX 63:1 in this listing is a SINGLE-COMPONENT (or pre-mixed 2K) airless pump.
