UP Universal Parts 1LL8-21BS, 400-33BRAA Pump Stator

Description:

The UP Universal Parts ITL8 5" Pump Stator is used in progressive cavity pump systems to create a sealed pumping cavity with the rotor for transferring abrasive, viscous, and shear-sensitive fluids. Commonly installed in drilling mud pumps, wastewater treatment systems, chemical processing equipment, mining operations, and oil & gas applications requiring reliable low-shear pumping. Maintenance teams, OEMs, and system integrators use this stator for replacement, retrofit, and pump rebuilds to restore pumping efficiency, maintain flow rates, and extend equipment service life. 

Applications:

The UP Universal Parts ITL8 5" Pump Stator is used in progressive cavity pumps handling drilling mud, slurries, wastewater, chemicals, and other viscous fluids. It is commonly found in oil and gas drilling rigs, wastewater treatment plants, mining operations, paper mills, and industrial processing facilities where smooth, non-pulsating flow and abrasion resistance are required. The 1LL8 series stators are aftermarket drop-in replacements compatible with popular pump families including MOYNI L8, TARBY TL8, and Continental CL8 series pumps.
