Waukesha Cherry-Burrell Universal II 030U2-SP Positive Displacement Rotary Lobe Pump 316SS with Marathon 3HP Motor and Falk Gearbox

The Waukesha Cherry-Burrell Universal II 030U2-SP is a sanitary positive displacement rotary lobe pump designed for handling viscous, shear-sensitive, and particulate-laden fluids in industries such as food and beverage, pharmaceuticals, and cosmetics. Constructed from 316 stainless steel, it ensures corrosion resistance and compliance with 3-A sanitary standards, making it ideal for hygienic applications. Key features include non-galling alloy rotors for gentle product transfer, CIP/SIP capabilities for easy cleaning, and front-access seals for quick maintenance. The 'SP' designation likely indicates special configurations, such as customized porting or seals. This assembly includes a Marathon XRI 3 HP severe-duty motor (460V, 1750 RPM) and a Falk Ultramite gearbox with a 9.705:1 ratio, reducing pump speed to approximately 180 RPM for optimized performance in low-speed, high-torque scenarios. Benefits include reliable volumetric efficiency, self-priming ability, and bidirectional operation, offering advantages over centrifugal pumps in maintaining consistent flow regardless of viscosity or pressure changes. Compared to competitors like Alfa Laval SRU or Fristam FKL, it excels in durability and ease of disassembly. Drawbacks may include higher cost and the need for periodic rotor inspections. Based on attached images, the unit is in used condition with minor wear, clean components, and no visible damage; serial number 417956 on pump, 420175 on gearbox. Estimated manufacture year 2003 from gearbox date.
