What makes the Waukesha 200 Series different from standard centrifugal pumps?

The Waukesha 200 Series offers robust sanitary construction, high hydraulic efficiency, and reliable performance designed specifically for food, dairy, beverage, and light industrial applications. These pumps deliver smooth flow, excellent cleanability, and long-term dependability.

Are the Waukesha 200 Series pumps easy to maintain?

Yes. The 200 Series features straightforward, hygienic design, easy access to wetted components, and readily available replacement parts — minimizing downtime and simplifying routine maintenance.

How do I size the correct Waukesha 200 Series model for my process?

Proper pump selection depends on flow rate, product viscosity, required discharge pressure, and system design. Williams-Carver provides application support to evaluate your operating conditions and match the correct 200 Series pump to your performance needs.

Waukesha 200 Series Pump

Product Overview

The Sanitary 200 Series pump is built for heavy-duty, high-efficiency applications and offers outstanding corrosion resistance. Its one-piece impeller and shaft design connects directly to the motor shaft, eliminating common issues such as:

Vibration
Short bearing life
High NPSH requirements
Frequent seal maintenance
Poor alignment
Adverse operating conditions

Waukesha 200 Series Pump

Key Features

316L stainless steel volute, backplate, impeller, and shaft for superior hygiene and durability
Five-bladed impeller with deeper eye for enhanced inlet performance
Modular seal design—one size fits all models for simplified maintenance
Wide range of seal options, including standard commercial seals
Robust JM-type motor with large bearings and a strong shaft for extended service life
Base mounting options are available across all sizes
Handles fluid temperatures up to 450°F (232°C)

Options

The 200 Series one-piece impeller/shaft sleeve design not only extends the life of seals, but it also reduces the number of shaft seal sizes to one, resulting in a minimum spare parts inventory requirement. These stationary seals are designed to last longer with a siliconized carbon (standard) lapped seat that is replaceable and reversible. This provides an excellent mating surface for the variety of rotary seals, including food-grade hard carbon, siliconized carbon, silicon carbide, and tungsten carbide. No matter how demanding your application, there’s a Waukesha seal that’s tough enough to handle it. Waukesha’s pump offering includes eight sizes of pumps from 4.5” (114 mm) to 10.5” (267 mm) impeller diameter. All use the same size seal.

An optional water cascade attachment is available for handling products that tend to crystallize. It also protects the seal against overheating due to high vacuum conditions or high product temperatures. For particularly adverse applications, 200 Series pumps are also available with an external balanced seal with a replaceable silicon carbide mating surface. The water-cooled rotary double seal (Double Mechanical Seal Cutaway) features two seals fully enclosed with a stainless steel seal housing. Water or other suitable coolant circulates through the housing under moderate pressure to cool the seal surfaces.

Theory of Operation:

Centrifugal Pumps

A centrifugal pump operates by converting mechanical energy from a rotating impeller into kinetic energy within the pumped fluid. In sanitary centrifugal pumps such as those from Waukesha and APV, fluid enters the pump through the inlet eye at the center of the impeller. As the impeller rotates at high speed, centrifugal force accelerates the fluid radially outward along the impeller vanes, increasing its velocity.

This high-velocity fluid then enters the volute casing, where the expanding geometry converts velocity into pressure, producing a smooth, continuous flow at the discharge. The precision-machined volute, enlarged ports, and hygienic impeller designs used in Waukesha and APV pumps help minimize turbulence, reduce shear, and improve efficiency, making them ideal for sanitary applications requiring gentle product handling, cleanability, and consistent flow performance.
