UC436L Sealless Chemical Pump

Sept. 4, 2021

An addition to the ULTRAChem lineup of heavy-duty ANSI dimensional mag-drive sealless centrifugal chemical pumps, the UC436L pump transfers the harshest types of industrial fluids such as sulfuric acid, sodium hydroxide, and sodium hypochlorite.


ULTRAChem (UC) Series pumps are engineered for maximum reliability in the most extreme chemical processing applications, including offering superior corrosion resistance over other pump constructions. The company currently offers 18 ULTRAChem pump models to cover a wide range of flow and head requirements.


Performance features of the UC436L pump include smaller impeller diameters compared to the high flow UC436, down to 4.25 in.; maximum flow rates of 440 gpm (100 m3/hr) at 3,500 rpm and 457 gpm (104 m3/hr) at 2,900 rpm; heads up to 164 ft (50 m) at 3,500 rpm and 115 ft (35 m) at 2,900 rpm; and a minimum flow rate of 5 gpm (1.1 m3/hr). It is constructed from tough ductile iron with ETFE lining for superior corrosion resistance and is manufactured in the USA.
