Comet's TW 500 Series of triplex pumps exhibits crankcases manufactured out of die-case aluminum alloy materials. These deliver comprehensive levels of corrosion resistance. The pumps sport encapsulated valve seats, complete with O-rings and anti-extrusion capabilities, depending on the model configuration (versions with pressure rates that start at 275 bar/4,000 psi). They also feature stainless steel check valves, a large oil capacity, and ceramic solid plungers. Coupling systems between pump heads, and crankcases that stop dirt and dust from penetrating piston operating areas are also showcased.

Other features of the TW 500 series includes single-piece bronze alloy connecting rods, stainless steel guide pistons, and crankcase oil sealing systems that minimize wearing on pistons oil seals. Models of the series also offer solid 24-mm shafts, oversized bearings, and O-ring sealing systems.
