Twin Screw Pumps. One platform for product + CIP
Twin screw pumps are a serious option when sanitary or high-purity processing needs gentle, low-pulsation product transfer and high-speed CIP cleaning duty from one pump platform. Triplex Sales represents two strong platforms: WANGEN Twin NG and the Waukesha Universal Twin Screw pump.
When the pump has to be gentle during production and fast during cleaning.
The twin screw conversation usually starts when a plant wants fewer components, better product handling, or one pump platform that can cover production transfer and cleaning media in the same sanitary path.
Two twin screw platforms. Different strengths, same sizing discipline.
Triplex Sales can help compare the WANGEN and Waukesha platforms against the real duty point: product, flow, pressure, viscosity, suction conditions, cleaning method, seals, and documentation needs.
WANGEN Twin NG
Sanitary twin screw platform for product transfer and CIP capability, with fast-X-change screw service, cartridge seal access, and VarioTwin forced-feed options for products that need help reaching the pump inlet.
Waukesha Universal Twin Screw
Twin screw technology from the Waukesha Universal family for high-purity process applications where gentle handling, cleanability, and Waukesha platform familiarity matter.
*Maximum values are model and application dependent. Always size from the actual product, temperature, pressure, suction conditions, solids, seal plan, and CIP requirements.
Useful when product quality and cleanability both matter.
Twin screw pumps are most interesting when the product is valuable, viscous, shear-sensitive, particulate-laden, or hard to clean out of the line.
Twin screw is not the answer to every pump problem. That is the point.
The right recommendation depends on the duty point. Triplex will compare twin screw against rotary lobe, centrifugal, AODD/EODD, or other pump types when viscosity, cleanability, suction conditions, high-purity requirements, or hard-to-handle fluids point in a different direction.
| Question | Why it matters | Triplex sizing note |
|---|---|---|
| What is the viscosity at pumping temperature? | Viscosity drives speed, suction, horsepower, and line loss. | Use the viscosity guide if product behavior is not clear. |
| Is CIP part of the same pump duty? | Cleaning flow may require a very different operating point than product transfer. | Confirm line size, cleaning velocity, temperature, and circuit restrictions. |
| Does the product need help feeding the pump? | Dense or non-flowable products may not gravity-feed into the inlet consistently. | Review WANGEN VarioTwin or other feed strategies when inlet conditions are the real problem. |
| What seal and elastomer risks exist? | Chemistry, temperature, solids, lubricity, and cleaning chemicals can decide uptime. | Start with the chemical compatibility guide, then verify final selection. |
Technical questions, answered plainly.
Can one twin screw pump handle both product and CIP?
In the right system, yes. A twin screw pump can run at production speed for product transfer and higher speed for cleaning media. Final selection still depends on cleaning velocity, line size, circuit layout, and plant standards.
When is twin screw better than rotary lobe?
Twin screw deserves a closer look when one pump platform needs to cover product transfer and CIP, or when the product is highly shear-sensitive, broad in viscosity range, or difficult to clean through a conventional layout. Rotary lobe pumps remain excellent for many sanitary PD duties.
What information does Triplex need to size one?
Flow rate, viscosity at temperature, differential pressure, suction conditions, product details, solids/particles, cleaning method, seal expectations, elastomer compatibility, and any current pump problems.
Documents that move the selection from interest to a real quote.
Twin screw selection gets better when the application data and support documents are close at hand. Use the product pages for platform-specific manuals and application notes, then use Triplex tools to check viscosity, line losses, and compatibility before the quote conversation gets too far downstream.
