Dense dough, fruit prep, high-viscosity product, and particulate transfer are where the Twin NG and VarioTwin story is easiest to understand: gentle product movement, controlled feeding, and cleanability in sanitary service.
VarioTwin forced-feed context
Dense dough does not reliably gravity-feed like water or juice. This is where VarioTwin's separately driven, coreless feed screw helps present product consistently into the Twin NG.
Gentle transfer of product with pieces
Twin screw geometry moves product axially with low pulsation and low shear — useful when product appearance, particulates, or structure matter.
04 — Features
Engineered for hygiene and uptime.
Every design choice — from fast screw changes to cartridge seals and self-centering alignment — is aimed at predictable operation in demanding sanitary process environments.
- Product transfer and CIP in one pump — high speed range lets the same pump move product and cleaning medium.
- fast-X-change® screw system — replace screws without re-synchronizing the screw shafts.
- Up to 80% screw-service time savings — brochure claim versus conventional screw-change technologies.
- Cartridge mechanical seals — old cartridge out, new cartridge in; single-acting and double-acting cartridge options are shown in the literature.

05 — Product + CIP
Product Pump + CIP Pump
One pump platform for process flow and cleaning flow.
With a conventional PD pump layout, processors often need a separate centrifugal CIP pump, bypass lines, valves, and controls to reach cleaning velocity. The Twin NG brochure positions the pump as a way to pump product and then run cleaning medium at high speed through the same production path.
That matters in crowded food plants: fewer components, fewer dead legs to engineer around, and a cleaner conversation for maintenance.
Final CIP layout depends on required cleaning velocity, line size, circuit design, and plant standards.
Catalog example from WANGEN brochure
WANGEN Twin NG 130
- Cleaning mode: 1460 rpm, 28 psi, 158 gpm.
- Tomato paste: 380 rpm, 112 psi, 44 gpm.

06 — Specifications
Four sizes, one hygienic platform.
These are the brochure maximums at 1 mPa·s where specified. Actual pump selection must be based on the real product, duty point, suction conditions, solids, seal plan, and CIP target.
| Model | Max particle size | Max flow rate | Max peak pressure | Good fit |
|---|---|---|---|---|
| Twin NG 70 | 3/4 in | 110 GPM at 4000 rpm | 30 bar / 435 psi | Smaller sanitary transfer, metering, pilot/skid duty. |
| Twin NG 104 | 1 in | 264 GPM at 3600 rpm | 30 bar / 435 psi | General food, beverage, dairy, sauce, cosmetic transfer. |
| Twin NG 130 | 1-1/4 in | 440 GPM at 3000 rpm | 25 bar / 363 psi | Higher capacity viscous product plus CIP duties. |
| Twin NG 180 New | 1.5 in | 880 GPM at 2600 rpm | 20 bar / 290 psi | Large sanitary transfer and bulk handling applications. |
Maximum ratings are model and application dependent. Flow, pressure, viscosity, particle size, and CIP requirements must be reviewed together before final selection.
07 — VarioTwin
For Non-Flowable Products
Add VarioTwin when the problem is feeding the pump.
The WANGEN VarioTwin NG is a forced-feed module for the Twin NG when a product is too viscous or too non-flowable to rely on gravity. The product overview positions it for food products up to 3,000,000 cP, especially as a supply unit for Twin NG 104 and 130.
For dense bakery, confectionery, fruit prep, and other non-flowable products, VarioTwin helps bridge the gap between the hopper or mixer discharge and the Twin NG pump inlet.
VarioTwin data sheet facts

08 — Selection Guidance
Twin screw vs rotary lobe: choose the right PD technology.
Both rotary lobe and twin screw pumps have a place in sanitary processing. Rotary lobe pumps are familiar, serviceable, and effective for many transfer duties. Twin screw pumps are usually considered when the application needs a wider speed range, product + CIP capability, low pulsation, or controlled feeding for difficult products.
| Application need | WANGEN Twin NG | Rotary lobe |
|---|---|---|
| One pump for product and CIP flow | Strong fit — high speed range supports product transfer and cleaning media. | May still require separate CIP pump/bypass depending on system. |
| Very wide viscosity range | Brochure range down to 0.5 cP and up to 1,000,000 cP. | Good PD option, but check slip and speed limits for thin fluids. |
| Gentle handling with particulates | Axial flow, low pulsation, low shear; particle size by model up to 1.5 in. | Often good for sanitary solids transfer; confirm rotor style and clearances. |
| Simplest familiar PD pump | More capability, but usually more application-specific. | May be the simpler choice for straightforward sanitary transfer. |
| Non-flowable product like dough | Consider VarioTwin forced-feed module with Twin NG. | May struggle without a feed device/hopper design. |

12 — FAQ
Questions customers actually ask.
Can one WANGEN Twin NG really handle both product and CIP?
Yes. The pump can run lower speed for product and higher speed for cleaning media. In the right system, that can reduce or eliminate separate CIP pump/bypass components. Final layout still depends on required cleaning velocity, line size, circuit design, and plant standards.
What is fast-X-change®?
fast-X-change is WANGEN's screw replacement system. The brochure states that screws can be replaced without re-synchronizing the screw shafts, reducing service time and possible timing errors.
Is the Twin NG 3-A certified?
The WANGEN brochure states that Pumpenfabrik Wangen GmbH is authorized to use the 3-A label for WANGEN Twin NG 70 3-A, 104 3-A, and 130 3-A. Confirm the exact certification package for the specific pump and options being quoted, especially seal configuration.
Can it run dry?
The Twin NG's contactless screws and the correct flushed or blocked mechanical seal plan help reduce dry-running risk during brief upset conditions. For applications where the pump may run without product, Triplex will confirm the right seal plan and protection strategy before quoting.
When do I need VarioTwin?
Use VarioTwin when the challenge is feeding a very viscous or non-flowable product into the pump. The VarioTwin data sheet describes a separately driven coreless feed screw, FDA-compliant guide housing, stainless wetted parts, and a 400 x 600 mm hopper.
How do I request a quote?
