HMD Kontro MMA 1.5x1x8H WA4 S26 Sealless Mag Drive Centrifugal Pump

This is a new HMD Kontro (Sundyne) MagMax series MMA 1.5x1x8H WA4 S26 sealless magnetic drive centrifugal pump — a fully hermetically sealed, shaft-seal-free design that eliminates all process fluid leakage paths, making it suited for hazardous, toxic, or volatile liquid transfer in chemical processing, petrochemical, and pharmaceutical applications. The model designation decodes as follows: MMA = MagMax close-coupled sealless design; 1.5x1 = 1.5-inch discharge x 1-inch suction flanged connections; 8H = 8-inch high-head impeller variant; WA4 = wetted end material code (wet-end alloy construction); S26 = motor/magnet drive frame designation. Per the nameplate, maximum design pressure is 275 PSI at 100°F, maximum process temperature is 248°F, and the unit carries a Class 1, Division II, Groups C & D hazardous location rating — confirmed on both the HMD Kontro data plate and the secondary Sundyne Corporation label visible in photos. The pump features flanged suction and discharge connections, a foot-mounted baseplate, thermistor motor protection, and the "DO NOT RUN DRY" and "DO NOT OPEN WHEN ENERGISED" warnings standard to this magnetically coupled product line; the motor end shows red-capped auxiliary connections and a high-voltage warning label consistent with the integral motor-magnet assembly design.
