Reliability of a Waukesha Pump 420

“Universal 420/520 High Capacity Pump – Reliability”

For more than half a century, Waukesha Cherry-Burrell has been a leader in the design, manufacturing and application of external circumferential, piston-type, positive displacement pumps. Waukesha PD pumps are in service around the world in food, dairy, canning, bakery, beverage and pharmaceutical processing, as well as challenging chemical and industrial applications.


Users of Waukesha pumps benefit from decades of continuing product improvement. Steady advances in design, metallurgy and fabrication techniques have yielded progressively higher levels of performance and service life. Over the years, this tradition has overcome countless pumping challenges — from high-viscosity to abrasiveness to metering accuracy.


The 420 & 520 models overcome a prodigious challenge: reliable and accurate pumping at high volume capacities. Every revolution of the Model 420 pumps more than 1.6 gallons (6 liters) of product. Model 520, more than 2.3 gallons (8.7 liters).


Significantly, Models 420 & 520 are not just scaled up Waukesha PDs. They incorporate fresh design approaches that simplify installation, ease pump maintenance and extend pump life.
