SPEAK TO US TODAY +27 31 701 52 55

TopWing series pumps are aseptic lobe pumps with an innovative design, created for demanding applications. They ensure high hygiene of operation, eliminating areas where product deposits can form, which reduces the risk of bacterial flora growth. Thanks to the two-wing lobes, they minimize the destruction of shear-sensitive media.

They are adapted to extreme conditions, offering a robust design, high efficiency and easy maintenance, which reduces operating costs. These pumps are characterized by the ability to operate at higher temperatures (up to 150 °C). They are available in versions with various types of seals and options, allowing horizontal or vertical mounting, making them versatile. The TopWing series has numerous hygienic certificates (EHEDG, 3-A), material certificates (3.1, FDA) and quality certificates (ISO 9001, ISO 14000) – thanks to this, the pump can be approved for ultra-hygienic applications.

Product features
  • Highest hygiene – rotor housing with automatic drainage and mechanical seal mounted in liquid. Made of low-carbon stainless steel with smooth surfaces.
  • Gentle product pumping – smooth-running rotors with minimized slippage, capable of transferring solid particles.
  • Certified design – EHEDG, 3-A, 3.1, FDA, USP VI and AFO certification, quality (ISO 9001) and environmental (ISO 14000) certificates.
  • 8 sizes – a range of models with a maximum capacity of up to 156 m3/h and pressure of 15 bar, which allows the pump to be adapted to specific customer requirements.
  • Integrated shaft and gearbox design – made of stainless steel, shaft bearings integrated with the rotor housing. Small shaft deflections and small clearances in the hydraulic part, as well as increased wear resistance.
  • Easy maintenance – product seals located at the front and a robust bearing assembly without retaining washers.
  • Wide choice of connections – threaded, clamp and flanged connections.
  • Wide selection of shaft seals – easy replacement with other types of seals, short downtime.
  • CIP/SIP capable – design enabling cleaning and sterilization in place, as well as manual cleaning.
  • Designed for use in potentially explosive atmospheres – compliant with the ATEX Directive, category II 2G.
Operation principle

The operating principle of a lobe pump is based on displacing a specific dose of liquid from the suction area to the discharge area by rotating the working elements (lobes). The lobes are mounted on shafts, which are supported by bearings in an external synchronizer. Shafts equipped with gears, located inside the synchronizer, transfer the drive from the drive shaft to the intermediate shaft. The lobes are synchronized so that they do not touch each other during operation.

As the lobes rotate, they increase the volume of the space between the teeth, causing a pressure drop on the suction port side (Fig. 1). This causes liquid to flow into the pump housing. The pumped liquid is transported inside the housing (Fig. 2 and Fig. 3) to the discharge side of the pump (Fig. 4). When the volume of the inter-lobe space decreases, it causes a pressure increase on the discharge port side, and consequently, the liquid is pushed out of the pump housing.

Construction

TW lobe pumps - construction

1. Highly hygienic design

  • self-draining working chamber in vertical position,
  • self-draining mechanical seal inside the working chamber,
  • 316 L stainless steel body and cover
  • smooth surface as standard, electropolishing on request
  • easy cleaning – CIP, SIP or manual
  • resistance to rapid temperature changes,
  • options with EHEDG and 3-A certificates

2. Rotary lobe pumps

  • minimal clearances on the lobes – less liquid backflow and gentle transport of shear-sensitive liquids.
  • uniform flow, low pulsation.
  • two-lobe or multi-lobe rotors.
  • made of Duplex steel, which improves temperature resistance and service life.

3. Working chamber and front cover

  • made of low carbon steel AISI316L
  • high hygiene
  • high corrosion resistance
  • self-draining in vertical position

4. Rear cover

  • made of stainless steel
  • high corrosion resistance
  • no need to paint the pump

5. Trouble-free operation and simplified maintenance

  • rotors, shaft and fixing screw made of Duplex stainless steel – more reliable assembly, less shaft deflection, high corrosion resistance and reduced wear
  • large shaft diameter
  • easy to clean on the outside without risk of corrosion
  • high strength design, increased bearing and seal life
  • shaft seal replacement without dismantling the working chamber
  • robust bearing design – preloaded tapered roller bearings without adjusting washers

6. High quality finish

  • Waterproof bearing construction with special seals minimizing water ingress
  • Stainless steel breather with check valve and labyrinth seal
  • Made of stainless steel – no corrosion, no painting
Impeller Types

Two-vane lobe rotor

Smooth operation with minimal damage to pumped media containing soft particles, such as fruit, and low pulsation when pumping viscous liquids.

Multi-vane cam rotor

Low noise level, low pulsation when pumping low viscosity liquids. Low NPSHr and reduced friction and power losses.

Options and accessories
Rectangular inlet For products with very high viscosity. Using a rectangular inlet significantly improves inlet conditions. Better NPSH, ability to pump denser media.
Relief valve Releases pressure inside the pump when it becomes too high. Available as spring pre-tensioned, spring pre-tensioned and air-balanced, or pre-tensioned and air-balanced. Thanks to easy cleaning and the air-balanced option, relief valves can also be used as a CIP valve controlled by the cleaning process.
Heating jacket Devices for pre-heating or cooling on the front cover and on the seals.
