iLOBE with integrated heat exchanger

Small Premium Edition

As an evolution of the conventional rotary lobe pump LC the iLOBE is equipped with an integrated heat exchanger for which IPP Pump Products GmbH holds a patent.

Additional strengths:

• complies with highest hygienic standard
• free of residues after CIP/SIP
• modular structure for handling of options
• increase of the passive security due to higher performance reserve
• screwable heatings (heat exchanger)
• various rotor options
• non-corrosive exterior

Technical concept

Our pumps open up new vistas

The contactless running of the pumping elements of rotary lobe pumps opens up important vistas: On the one hand the perfect suitability for hygienic applications as abrasion and product contamination can be fully eliminated and on the other hand the non-wearing of the conveying elements when pumping clean liquids. These attributes result in minimum life cycle cost. The contactless running of the pumping elements is guaranteed while maintaining the full capacity.

This poses a challenge to the designing of the gearbox. The external bearing of rotary lobe pumps must enable the pump to hold the rotor almost concentric and on the axial level centric in the rotor case in nearly all operation situations.

However, the non-contact of the pumping elements is contradictory to the capacity. The gaps which are essential for the non-contact allow a return-flow of the pumped medium from the pressure side to the inlet site. This return-flow through the gap is called “slip” which becomes noticeable mainly when pumping low-viscous media and cares for a cleaning without residues of the internal components of the rotary lobe pump.

Hygiene is its strength

Free of residues through self cleaning (CIP / SIP)

For important operating situations the characteristic slip of the centrifugal and rotary lobe pump is a most welcome side effect as the slip significantly ensures a cleaning function if all pump elements to be cleaned – from the rotor screw to the mechanical seal – are arranged in this flow path. Front loaded mechanical seals (integrated to the rotor) and plane housing covers, both are standard equipment at the iLobe, are imperative conditions for a cleaning without residues (CIP/SIP). Due to its innovative gearbox design the iLobe can run during the CIP/SIP-procedure, even with high temperature changes. The active running of the pump during the cleaning process is imperative for an effective CIP procedure as otherwise the slip volume flow which is important for the cleaning effect, wouldn’t arise.

Shaft seals

Serviceability

"Front-Pull-Out" -system for non-stop-availability.

The modular structure of the PREMIUMLOBE range is of particular use regarding the sealing. All different standard gaskets are accessible from the front as "Front-Pull-Out" –system and can be exchanged by each other at any time.

The selection of the sealing principle depends on many criteria relating to the plant and the product. Tungsten Carbide is the first choice for the mechanical seals, optionally SiC/SiC. The auxiliary gaskets can be made of NBR, Viton, Viton-FDA, EPDM, EPDM-FDA, PTFE or Perflour elastomer (Kalrez).

A choice of O –ring seals and lip rings complete the range of single and double acting mechanical seals.

Applications

The right pump for any application

ipp-rotary lobe pumps can be used for any individual requirements and operation conditions: For transfer, discharge (also from high vacuum), circulation and mixing, dispensing, atomizing, tank discharge and filling. Products like for example sugar, sugar coatings, starch, mashed potatoes, lard, vitamines, glucose syrup, coffee essence, lecithin, clycerine, baby food, salads, salad dressings, spices, sauces, mixings, gelatine, chocolate, dairy products etc. are part of this field of application.
