Lobe Pumps

When handling shear-sensitive or viscous fluids, standard pumps can cause product damage and reduce efficiency. Lobe pumps deliver smooth, gentle flow with capacities from 1 to 1,000 L/min, fitting many industrial needs.

Flow Rate Range

1 L/min to 1,000 L/min (0.26 GPM to 264 GPM) – High-capacity designs available

Pressure/Head Capacity

Up to 15 bar (217 psi) – Lower pressure than gear pumps

Power Requirements

0.5 kW to 75 kW (0.67 HP to 100 HP), 3-phase motors, 50/60 Hz, VFD optional

Materials of Construction

Housing: Cast Iron, Stainless Steel (304/316), PTFE-lined Rotors: 316SS, Nitrile Rubber, EPDM, PEEK

Fluid Compatibility

Sanitary Fluids, Slurries, Viscous Liquids, Shear-Sensitive Products (e.g., food, pharma, cosmetics)

Product Description

They operate at pressures up to 15 bar, offering lower pressure but safer handling than gear pumps. With flexible power from 0.5 kW to 75 kW, these pumps suit varied production scales and process speeds.

Temperature Range

-30°C to 200°C (-22°F to 392°F) – Higher temps with special seals/materials

Connection Types & Sizes

Tri-Clamp (Sanitary), Flanged (DIN/ANSI), Threaded (BSP/NPT) – Sizes: 25 mm to 150 mm (1″ to 6″)

Mounting Configuration

Horizontal or Vertical – Close-coupled, foot-mounted, or hygienic (sanitary) designs

Seal System

Mechanical Seal, Lip Seal, Double Seal, or Sanitary Seal-less (CIP/SIP compliant)

Efficiency Rating

70% to 85% (lower than gear pumps but gentler on product)

Viscosity Range

1 cP to 100,000 cP – Handles thick fluids without shear degradation

Speed Range

100 RPM to 800 RPM (lower speeds for viscous/solid-laden fluids)

Solids Handling Capability

Can pass solids up to 80 mm (3.1″) (depends on lobe design)

Certifications & Standards

3A, EHEDG, FDA, ATEX, ISO 9001 – Compliant for food, pharma, and hazardous areas

Operating Noise Level

< 75 dB(A) (quieter than progressive cavity pumps)

Coupling System

Direct Drive, Belt Drive, or Magnetic Coupling (for leak-free sanitary applications)

Technical Advantages

Lobe pumps use robust materials like stainless steel and PTFE lining for chemical resistance and longevity. The rotors allow passage of large solids without damage, reducing downtime in solid-laden processes.

Sanitary seal-less designs enable easy cleaning and compliance with strict food and pharma standards. The broad viscosity and temperature ranges provide operational flexibility across diverse industrial fluids.

Dependable Pumping for Sensitive and Viscous Fluids

Handling shear-sensitive fluids or thick slurries challenges many pump types, risking product quality and equipment life. Our lobe pumps offer gentle pumping with durable construction, maintaining fluid integrity under various operating conditions.

They adapt to sanitary, chemical, and industrial needs, ensuring smooth flow and reliable uptime. These pumps balance performance and care for fluids, supporting continuous production with minimal maintenance.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

What factors influence the choice between a lobe pump and other positive displacement pumps?

Lobe pumps excel with shear-sensitive and viscous fluids due to gentle handling. They offer lower pressure capacity compared to gear pumps but can pass larger solids. Buyers should consider fluid type, pressure needs, and cleaning requirements before deciding.

How does the seal system impact pump performance and maintenance?

Seal types affect leakage risk and ease of cleaning, especially in sanitary applications. Mechanical and lip seals suit general use, while seal-less magnetic drives reduce contamination risks. Selecting the right seal depends on fluid type, pressure, and hygiene standards.

Can lobe pumps handle fluids with suspended solids, and what size solids are acceptable?

Yes, lobe pumps can pass solids up to 80 mm depending on rotor design. This reduces clogging and wear in slurry or wastewater processes. You should specify solids size to match pump design and avoid operational issues.

What are the options for controlling pump speed and flow rate?

Variable frequency drives (VFDs) allow precise control of speed between 100 to 800 RPM. This flexibility helps optimize flow and reduces wear when handling thick or delicate fluids. Integrating VFDs supports energy savings and process adjustments.

How do material choices affect pump compatibility with different fluids?

Pump components use materials like stainless steel, PTFE, and elastomers to resist corrosion and abrasion. Material selection depends on fluid chemistry and temperature to prevent degradation. Buyers must review fluid properties to ensure long pump life and safety compliance.
