In today’s industrial landscape, handling high-viscosity fluids has become a mission-critical task. From heavy oils, bitumen, resins and pastes – to wastewater sludges, food pastes or polymer melts – many processes demand a pump that not only moves the fluid but does so efficiently, reliably, and with minimal shear or damage to the media. That’s exactly where our high-viscosity rotary lobe pump steps into the spotlight.
Our precision-engineered pump is designed for the most demanding media: fluids with elevated viscosities, fleeting shear sensitivity, suspended solids, or difficult flow behaviour. Whether your requirement is continuous transfer, batch dosing, gentle product handling, or abrasive-particle tolerance, this pump delivers.
Conventional pump technologies (centrifugal, simple gear pumps, peristaltic) often struggle when fluid viscosity grows, or when particles/suspension are present. Key issues include loss of flow, high slip (internal leakage), difficulty priming, elevated shear (which may damage sensitive products), and frequent maintenance.
Positive-displacement action: Each rotor revolution directly displaces fluid, offering stable flow regardless of viscosity. For example, manufacturers list viscosity capability up to 1,000,000 cP (centipoise) or more.
Gentle, low-shear handling: The lobes do not grind fluid against each other; the design avoids high shear zones – critical for shear-sensitive or thixotropic media.
Excellent solids handling: Many models tolerate soft or even semi-solid particles suspended in the fluid without clogging.
Self-priming and reversible flow options: Useful for challenging suction conditions or systems requiring flow reversal.
Viscosity capability: Up to 1,000,000 cP or more in some models.
Flow rate range: From small precision units (0.1 m³/h) up to large industrial units (e.g., 40 m³/h or greater).
Pressure differential: Many models manage up to 15–20 bar (or higher depending on size).
Temperature range: From low (-40 °C) to high temperatures (e.g., +150 °C or more) depending on materials.
Construction materials: Wetted parts often in stainless steel 316L/304, sometimes with corrosion-resistant alloys (Hastelloy, Duplex, Titanium) for aggressive media.
Seal options: Mechanical seals, double seals, flushable designs – selected to match abrasive, high-temperature or hygienic applications.
This flagship model is engineered for heavy-duty performance:
Power: 18.5 kW motor drive
Flow rate: Approx. 160-200 m³/h (model dependent)
Abrasion/impurity tolerance: Built for sludge, heavy oils, and media containing suspended solids
Non-clogging design: Robust internal geometry and bearings designed for high load.
It exemplifies our commitment to delivering reliable, high-capacity solutions for demanding industrial media.
Another compact option is the 5.5 kW Rotary Lobe Pump, which offers 35-60 m³/h flow and is ideal for moderate high-viscosity applications with lower budget or space constraints.
Industries such as oil refining, asphalt facilities, and heavy-duty marine bunkering require pumps capable of moving viscous hydrocarbon fluids. Our rotary lobe pump handles high-viscosity oil streams, controlling shear and maintaining stable delivery under difficult conditions.

When transferring high-viscosity resins, acrylic coatings or thick polymer pastes, shear sensitivity and product integrity become critical. As one manufacturer notes: “Designed for high-viscosity acrylic resin coatings (8,000-50,000 cP) … the pump preserves the resin’s rheological stability.”
Even in sanitary applications, high-viscosity media like creams, yogurts, sauces or chocolate need pumps that maintain consistency and meet hygienic standards. Our pump design supports such uses, with CIP/SIP compatibility.
Wastewater Sludge & Industrial Slurries
High dry-matter sludge, waste solids and particle-laden slurries pose serious challenges to pumps. The rotary lobe pump is engineered for heavy-duty duty, allowing solids up to 61 mm according to some specifications.
Low operational speed / minimal shear: Reduces thermal damage, maintains product quality, especially important for sensitive media.
Robust materials & finishes: Wetted parts in stainless steel or speciality alloys, surface finishes (e.g., Ra < 0.8µm) in hygienic versions.
Easy maintenance & long service life: Modular components, minimal wear parts, front-loaded seals simplify upkeep.
Self-priming & reversible flow capabilities: Useful for systems where suction conditions are difficult or flow reversal is required.
Low noise & vibration: Because of positive‐displacement and smooth rotor action, the pump offers quiet, stable operation—good for plant environments.

Drive & control options: Does the pump need variable speed drive (VSD) for viscosity changes?
Budget & lifecycle cost: A robust pump may cost more upfront but reduce downtime and maintenance significantly.
By choosing a pump purpose-built for high-viscosity service, you benefit in multiple ways:
Fewer production stoppages from clogged or stalled pumps
Lower maintenance and spare-part costs
Better product integrity (especially for sensitive media)
Reduced energy waste (due to efficient design)
Longer service life and reliability in harsh conditions
