Stainless Steel Rotary Lobe Pump: Reliable Transfer of High-Viscosity Liquids
Struggling with Thick Liquids, Temperature Changes, or Strict Hygiene Requirements?
Transferring viscous products such as syrup, cream, grease, and cosmetic ingredients can be challenging. Ordinary pumps may struggle with changing viscosity, while unsuitable materials or temperature conditions can affect product quality and production efficiency.
This stainless steel rotary lobe pump is designed for transferring high-viscosity liquids across food processing, pharmaceutical, cosmetic, and chemical applications. With SS304 or SS316 construction, multiple rotor designs, and an optional heating or cooling jacket, it offers flexibility for different process requirements.
Instead of choosing a pump based on specifications alone, start with the challenges in your production process.
1. Struggling to Transfer High-Viscosity Materials?
Thick liquids require a pump suited to their viscosity and flow requirements. This rotary lobe pump is designed for high-viscosity media, including syrup, grease, creams, and other compatible process fluids.
How does this help your application? It provides a positive-displacement pumping solution for demanding liquid transfer processes where viscosity can vary significantly.
2. Need to Maintain Product Temperature During Transfer?
Some materials become difficult to pump when they cool, while others require cooling to maintain process conditions. An optional heating or cooling jacket can accommodate suitable media, such as hot steam, thermal oil, or coolant, depending on the process.
How does this help your application? It helps manage pump temperature during transfer and can support processes that require heating or cooling.
3. Concerned About Hygiene and Material Compatibility?
In food, beverage, pharmaceutical, and cosmetic production, wetted materials and surface finish are important. The pump is available in SS304 or SS316 stainless steel, with surface treatment and connection options to suit different installation requirements.
How does this help your application? It gives you material and configuration options for evaluating compatibility with your product and cleaning procedures. Confirm the required hygienic standard and certifications for your application before ordering.
4. Need Flexibility for Different Production Processes?
Different liquids and production lines may require different flow rates, rotor designs, and connections. Options include single-lobe, tri-lobe, and butterfly-type rotors, along with clamp, threaded, welded, or flanged connections.
How does this help your application? You can evaluate a configuration that better matches your liquid properties, pipeline design, and process requirements.
5. Looking for Long-Term, Low-Wear Operation?
Frequent maintenance and rotor wear can increase operating costs. The rotor design uses an outer rotor to drive the inner rotor in the same direction, helping reduce relative wear under suitable operating conditions. Adjustable rotor clearance may also be available to accommodate different viscosity requirements.
How does this help your application? It offers design features intended to support durability and adapt the pump to different process conditions. Actual service life depends on the liquid, operating parameters, and maintenance.

Match the Pump to Your Application, Not Just a Model Number
A pump may look suitable on a specification sheet without necessarily meeting your actual process requirements. The right choice depends on liquid viscosity, required flow rate, operating temperature, discharge pressure, material compatibility, and cleaning requirements.
To help evaluate the right pump configuration, please share these four details:
- Liquid: What product do you need to transfer?
- Viscosity: What is the approximate viscosity in cP or mPa·s?
- Flow Rate and Pressure: How much liquid do you need to transfer, and at what discharge pressure?
- Temperature and Hygiene Requirements: Does the process require heating, cooling, or a specific sanitary standard?
With this information, we can help assess material compatibility and identify the pump configuration that best fits your production process.
