Wangen Twin NG70 Screw pump

• Transfer of viscous food products such as sauces, yoghurts, and purees.
• Pumping shear-sensitive beverages like fruit juices and concentrates.
• Handling cosmetic creams, lotions, and gels requiring hygienic transfer.
• Processing chemical solutions where precise and gentle pumping is critical.
• Managing pharmaceutical ingredients and formulations under sanitary conditions.

Pump Type

Twin Screw Pump (often miscategorised as Peristaltic; it is a positive displacement rotary pump)

Typical Capacity

For this class of equipment, flow rates commonly range from a few m³/hr up to approximately 100 m³/hr, depending on model specifics and product viscosity.

Pressure Capability

Units of this type are typically capable of discharge pressures up to 20 bar, suitable for various transfer and dosing applications.

Viscosity Range

Designed to handle a wide range of viscosities, from low-viscosity liquids to highly viscous pastes and slurries.

Materials of Construction

Process-contact parts are typically 316L stainless steel for hygiene and corrosion resistance, as indicated by the listing.

Power Supply

Commonly requires a 3-phase electrical supply, typically 400V, 50Hz in the UK, as specified in the listing.

Control System

Modern units, like this one, often feature HMI touchscreen controls for precise operation and integration.

Mobility

Many units are mounted on mobile stainless steel skids for flexibility in plant layout and ease of cleaning.

• What is the difference between a twin screw pump and a peristaltic pump?

  A twin screw pump uses two intermeshing screws to move fluid, offering excellent suction and handling of viscous products. A peristaltic pump compresses a tube to push fluid, ideal for abrasive or shear-sensitive media, but typically at lower pressures and flow rates.

• Is this pump suitable for CIP (Clean-In-Place)?

• Can this pump handle products with solids?

• What maintenance is typically required for a twin screw pump?

• What are the advantages of a mobile skid-mounted pump?

• What kind of HMI controls are typically found on these units?

Peristaltic pumps are valued in laboratory and pharmaceutical settings for their gentle, non-contact fluid handling, making them suitable for delicate samples and sterile applications. When buying used units, buyers typically prioritise checking tubing condition, motor functionality, and calibration history. Industry sentiment favours these pumps for their reliability, low maintenance requirements, and consistent flow rates. Common strengths include versatility across various fluid viscosities and compatibility with corrosive or shear-sensitive media. Prospective buyers should verify spare parts availability for specific models.
