    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.

    Mechanical aspects

    Ensure the contactless running of the pumping elements

    1. Bending of the shaft due to differential pressure:

      The bearing and the shafts of the iLobe-gearbox are designed for a minimum shaft bending which means that all models can be operated with fully contactless pumping elements at thet indicated differential pressures. And that with a high volumetric effect, i.e. with small gaps. Differential pressures up to 40 bar at cold commissioning and up to 80 bar with product can be reached. Corresponding pressure resistant housing parts, as for example connectors are chosen in accordance with the requirements.
    2. Different temperature strains of the single components:

      The selection of material for the components and their dimensions guarantee that the PREMIUMLOBE can run without restrictions during the CIP- and SIP-procedure, without risk of blooming at the pump case cover or pump case.
    3. Settlements as well as elastic deformation of the synchronisation gearbox:

      Through a new combination of force and form locking the synchronizer gear wheels are safe against settlements and loss of timing. This ensures the perfect functioning of the pump on a long term. The gearbox housings are torsion proof.

    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.

    More information

    Shaft seals


    "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.


    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.

    Dairy products

    Dairy products

    ipp pumps cover the vast range of the food stuff industry and are also suitable for a number of media and applications particularily in the dairy industry: they can be used for butter - solid or liquid, quark, yogurt, curd cheese, cream, pudding. Centrifugal pumps are very well suited for the CIP flow and return flow as well as for milk.




    To pump eggs, mayonnaise, dressinggs, sauces, marinades, spice mixes and soups as well as stews, ketchup, mustard or tomato puree carefully is a speciality of ipp pump products. Of course the pumps comply with the strictes hygienic requirements and can be cleaned easily and time and cost saving.



    Chemical Industry

    For transfer, discharge (also from high vacuum), circulation and mixing, dispensing, atomizing, Tankannahme and filling ipp rotary lobe pumps can be selected for any individual requirement and operation conditions.
    The pumps allow the pumping of flavourings, acids and alkalis, paints and varnishes, poylmers, resins, wax, solvents, glue and adhesives, binders, latex, glyzerin, lecithin and hydrocarbons with pressures up to 80 bar and high viscosities.
    The ipp range also offers you barrel discharge pumps which are chemical resistant.



    With the products from ipp Pump Products GmbH you gently pump alcohol, beer, yeast, fruit juice, lemonades as well as mineral water, fruit juice concentrates, liquor, wine, syrup. The rotary lobe pump Premiumlobe as well as the barrel discharge pump FLB are suited for viscous media, the centrifugal pumps for the aqueous media.



    The efficient and at the same time gentle pumping of cosmetic products is one of our strengths: shampoo, shower gel and soaps, lotions, cream, lipstik, suntan oil, perfume, gels and even wear promoting media like tooth paste sometimes place extreme demands to positive displacement pumps. A rotary lobe pump from ipp Pump Products GmbH is developed and manufactured individually in compliance with your requirements.




    Pumping chocolate, marzipan paste, liquid sugar, fudge, jam, marmelade, honey, fruit preparations, sugar mixtures, starch or cocoa butter without affecting their quality and consistence - a challenge which we take on with a lot of experience and innovation power. The sugar contents place very high demands to the shaft seals and the temperature - ipp pumps meet all hygienic requirements and are easily cleanable, i.e. particular suited for chocolate and sweets.


    Bakery products

    Bakery products

    You wish to pump dough, fats, fillings, coatings, cream, chocolat or raw products like for example glucose syrup or lecithin: ipp rotary lobe pumps are equal to this sophisticated task under hygienic conditions. Even sticky tough masses are no problem. The pumps are mechanically robust, versatilely trimmable and can be cleaned perfectly.

    The indicated data may only be evaluated individually. The simultaneous appearance of multiple performance limits may be incorrect. In practice the practicable values may vary, depending on the type of product, respectively on the design of the plant in which the pump is integrated.

    The operation limits are variable. In particular Δ p max can be higher at certain applications. For a precise dimensioning a detailed examination of the operating conditions is necessary.
