Flow performance up to 100 m³/h with differential pressure ratings up to 80 bar
Full compliance with EHEDG and 3A hygienic standards for clean CIP and SIP wash
Even Wall stator technology ensures uniform elastomer thickness and high pressure
Sanitary spare parts: aseptic open pin joints, polished rotors, and face seals

Pump Selection Based on Viscosity and Rheology

WANGEN displacement pumps are specified according to fluid rheology and process dynamics. For Newtonian and non-Newtonian media with high viscosity, the KL-S progressive cavity series provides continuous flow without pulsation.

When handling shear-sensitive fluids or adhering to sterile processing standards, Twin NG twin screw pumps deliver optimal laminar conveyance while matching piping resistance and temperature requirements.

Handling High Solids Slurries and Fibrous Matter

Transferring dewatered municipal sludge, solid organic manure, and biomass calls for specialized hopper geometries. Systems like BIO-MIX and KL-R Triplex feature heavy-duty hoppers, integrated augers, and bridge breakers to maintain steady flow.

The Xpress series offers a spherical solid clearance up to 73 mm to prevent clogging when conveying fibrous media.

Elastomer Stator Compounding for Chemical Duty

The operational life of a progressing cavity pump depends on matching the stator elastomer to the chemical medium. Nitrile butadiene rubber (NBR) serves oily and abrasive slurries, whereas fluoroelastomer (FKM) withstands aggressive solvents, acids, and elevated temperatures.

Food and pharmaceutical duties utilize qualified white EPDM or NBR elastomers compliant with global sanitary criteria.

Dual-Duty Operation of Hygienic Twin Screw Pumps

WANGEN Twin NG hygienic twin screw pumps are built for dairy, food, beverage, and personal care manufacturing. Non-contacting stainless steel screws eliminate internal friction and prevent metallic contamination.

The broad speed regulation bandwidth enables a single installation to handle delicate product transfer at low speed and high-velocity CIP fluid circulation without supplemental centrifugal pumps.

Drive Efficiency and Speed Regulation Parameters

Integrating variable frequency drives with WANGEN pumping systems optimizes plant power consumption and extends component durability. Modulating shaft speed precisely matches required line throughput without relying on energy-wasting bypass loops.

Furthermore, progressive ramp-up profiles reduce startup torque on drive couplings, cardan linkages, and motor bearings.

Preventive Inspection and Mechanical Seal Integrity

Scheduled preventive maintenance focuses on monitoring suction and discharge manometers, bearing frame operating temperatures, and mechanical seal integrity.

Periodic inspection of stator wear and rotor clearances ensures planned replacement of elastomeric wear components during scheduled turnarounds, avoiding unexpected production outages.
