How to choose a Yourt Transfer Pump?

As a procurement or production manager in a yogurt manufacturing facility, you know that every piece of equipment on your line impacts your final product. But few are as critical—and as potentially problematic—as the pump that transfers your delicate yogurt. Choosing the wrong pump can lead to a host of issues: from compromised texture and syneresis (whey separation) to clogged lines and costly downtime.

This guide isn't written by a salesperson. It's written from the perspective of someone who understands your challenges. Think of it as a checklist from a fellow industry professional to help you navigate the selection process and make an investment that protects your product quality and your bottom line.

First, let's reframe the objective. The goal isn't just to move yogurt from Tank A to Filler B. The goal is to do so while perfectly preserving the viscosity, mouthfeel, and live cultures you've worked so hard to cultivate. Your lobe pump is a guardian of quality. This mindset is crucial for evaluating options beyond just the initial price tag.

Second, use these five dimensions as your core evaluation criteria when speaking with potential suppliers.

1. Gentle Handling & Low-Shear Performance

• Key Question to Ask: "How does your pump demonstrate its low-shear properties, and how can it protect the texture of our Greek or stirred yogurts?"

• What to Look For: Avoid centrifugal pumps that impart high shear. Instead, focus on positive displacement pumps like Rotary Lobe Pumps. Their low-speed, continuous flow action is ideal for shear-sensitive products. Ask about the pump's RPM range and how its design minimizes mechanical agitation.

2. Ability to Handle Complex Recipes

• Key Question to Ask: "What is the maximum viscosity (in cP) this pump can handle? Can it convey yogurt with fruit pieces, jam, or granola inclusions without damaging them?"

• What to Look For: Inquire about the pump's "particle-handling capability." The size of the pump's lobes and the internal clearances will determine if it can pass inclusions smoothly. Request to test the pump with your actual product mix.

3. Hygiene Standards & Cleaning Efficiency

• Key Question to Ask: "Are all wetted parts made of 316L or equivalent stainless steel? What is the surface finish? Is it fully CIP/SIP capable, and how easy is it for manual disassembly and inspection?"

• What to Look For: Demand hygienic design certifications like 3-A or EHEDG. A pump that cleans quickly and thoroughly reduces downtime and labor costs. The ability to perform Clean-in-Place (CIP) is non-negotiable for modern dairy operations.

4. Efficiency, Reliability & Total Cost of Ownership (TCO)

• Key Question to Ask: "What is the typical energy consumption? What are the maintenance intervals, and how easy and costly is it to replace wear parts like seals?"

• What to Look For: Think beyond the purchase price. A slightly more expensive but robust, energy-efficient, and easy-to-maintain pump will have a lower TCO over its lifespan. Reliability is cheaper than frequent repairs and production stoppages.

5. Supplier Expertise & Support

• Key Question to Ask: "Can you provide case studies or references from other yogurt producers? What does your technical support and spare parts availability look like?"

• What to Look For: You're not just buying a machine; you're choosing a partner. A supplier who deeply understands dairy processing can offer invaluable advice and reliable long-term support.

Selecting the right yogurt transfer lobe pump is a strategic decision that safeguards your brand's reputation for quality. By focusing on these five areas, you can make a confident, informed choice.

What are the critical advantaged of Bonve lobe pump to transfer high viscous products?

Special bearings tructure

The inner gear box is designed with six separately arranged bearing structures (each shaft has three bearings), so that the shaft is stressed at three points in one, and then processed by high-precision equipment, so that the rotor and the pump body have no friction coefficient.

This design greatly increases the concentricity of the pump operation, enhance the bearing capacity of the shaft and make the structure more stable, thereby increasing the service life of the shaft, the mechanical seal and complete pump.

Special shaft fixing way

The combination of synchronous gear and shaft adopts key structure design to replace of shrink disk, so as to avoid the phenomenon of gear slipping or rotor collision when the pump is under high pressure, high viscousity and instant start.
