Hygienic Pumps for Liquid Transfer | Twins Screw pump

To choose the right hygienic pump for your food processing line, match the pump design to your product characteristics, operating conditions, and sanitation requirements. Start by evaluating viscosity, texture (smooth vs. textured), and whether your product contains suspended solids or abrasive particles — because these factors determine which pump type performs best.
For thin, free-flowing liquids, many facilities begin with **centrifugal pumps** for efficient transfer. If your formulation is extremely delicate and you need gentle handling, **peristaltic pumps** can help minimize shear. However, when products are thicker, shear-sensitive, textured (such as sauces, creams, and dressings), or solids-containing, **twin screw pumps** are often the preferred hygienic solution due to their stable, low-pulsation, positive-displacement flow.
Finally, confirm your cleaning strategy. If you require fast, repeatable sanitation, prioritize food-grade hygienic pumps designed for CIP (and SIP where applicable). A well-matched selection helps protect product quality, supports reliable cleaning, and reduces downtime across production runs.

• 1) Identify your product characteristics
• 2) Confirm your required flow and pressure
• 3) Evaluate hygiene and cleaning needs
• 4) Consider shear sensitivity and product integrity
• 5) Choose the right sealing and materials
• 6) Plan for installation and service

When these factors are aligned, you get a hygienic liquid transfer solution that performs consistently across production runs — while meeting the sanitary expectations of modern food processing.

Greater Flexibility

The Twinscrew pumps feature a modular design with 12 available models, helping you match the right pump to your application for reliable hygienic liquid transfer. This model range supports stable performance across different product viscosities and solids levels, while offering the right pressure capability for your process needs. With a cost-effective configuration for each duty, customers can improve durability, reduce lifecycle costs, and minimize downtime through simplified maintenance and service.

When you’re choosing between twin screw pumps and lobe pumps for food processing, the “best” option depends on how your product behaves and how strict your hygiene and flow requirements are.

Twin screw pumps are positive displacement screw pumps designed for stable, low-pulsation transfer — often making them a strong choice for textured, high-viscosity, or shear-sensitive foods (such as sauces, dressings, creams, and dairy concentrates). Their geometry supports consistent dosing and can help reduce product damage, while hygienic pump design supports reliable cleaning for food-grade pumps.

Lobe pumps can also be used in food applications, especially where gentle handling is needed. However, if your process demands very steady, virtually pulse-free flow for viscous or solids-containing formulations, twin screw pumps are frequently selected because they maintain consistent transfer characteristics across a wider range of product conditions.

In short: if your priority is hygienic, low-pulsation twin screw pumps performance for viscous, textured, or shear-sensitive products, they’re often the better fit. If you want, share your product viscosity, solids level, and required flow/pressure, and we can help you compare the right pumps for your line.

Sanitary Operation

The Twinscrew hygienic fluid transfer pumps are designed for food and beverage processing where sanitation and regulatory compliance matter. They feature hygienic, cleanable construction that supports thorough washdown and helps minimize contamination risk. The pumps are EHEDG accredited and conform to the 3-A Sanitary Standard, and they are suitable for both CIP and SIP — so you can clean and sanitize the same hygienic unit used for product transfer.
For additional assurance, these food-grade pumps are built around sanitary design principles such as hygienic media-contact surfaces and reliable sealing arrangements, helping support consistent, repeatable cleaning between batches.

CIP in place

Two-in-one operation provides easy handling of process media of varying viscosities as well as CIP fluids. This simplifies piping and pump control, cutting costs and minimizing contamination risks.

Multiple Seal Options

The optimum seal can be chosen to match your pumped media requirements and duty conditions. Single or double mechanical seals are available and include flushed or aseptic variants. For arduous conditions, hard faced seal materials can be used. Plus, packed glands offer a simple, low cost, and easy to maintain controlled leakage sealing arrangement.

Pump Performance, Durability, and Cost Considerations

Pump Performance

Selecting the right food grade pump starts with understanding the performance requirements of your process. Twin screw pumps are engineered to deliver stable, low-pulsation flow across a wide operating range, making them suitable for both low- and high-viscosity products.

Key performance advantages include:

• Consistent flow rates for accurate filling, dosing, and transfer operations.
• Gentle product handling that helps preserve texture, appearance, and product integrity.
• Excellent suction capability with low NPSHr, improving product recovery and reducing waste.
• Reliable handling of products containing suspended solids without compromising performance.
• The ability to process both product and CIP fluids using the same pump, reducing equipment requirements.

Whether transferring dairy products, sauces, syrups, creams, beverages, or personal care liquids, twin screw pumps provide the flexibility needed to maintain efficient and repeatable production.

Durability and Long-Term Reliability

In food and beverage production environments, equipment reliability directly impacts productivity and operating costs. Twin screw pumps are designed for demanding continuous-duty applications and frequent washdown procedures.

Features that contribute to long service life include:

• Product-contact components manufactured from corrosion-resistant AISI 316L stainless steel.
• Diffusion-hardened pump casing and screw options for enhanced wear resistance.
• Robust gearbox construction designed for reliable operation under varying process conditions.
• Front-loading cartridge seal designs that simplify maintenance and reduce service times.
• Hygienic construction that supports regular CIP and SIP cycles without compromising performance.

These design features help minimize unplanned downtime, extend component life, and maintain consistent product quality throughout the pump's operating life.

Cost Considerations and Total Cost of Ownership

While initial pump selection is important, long-term operating costs often have a greater impact on overall process economics. Evaluating total cost of ownership helps ensure the most cost-effective solution for your application.

Factors that influence operating costs include:

• Energy consumption during continuous production and cleaning cycles.
• Maintenance requirements and the ease of servicing wear components.
• Downtime associated with cleaning, inspections, and seal replacement.
• Product loss due to inefficient recovery or product damage.
• The need for multiple pumps versus a single pump capable of handling both process and CIP duties.

Because twin screw pumps combine product transfer and CIP functionality in a single unit, many facilities can reduce equipment complexity, simplify piping systems, decrease maintenance requirements, and lower long-term operating costs. Their ability to handle a wide range of products also provides flexibility for future production changes, helping maximize return on investment.

When evaluating hygienic pumps, considering performance, durability, and lifecycle costs together can help identify the solution that delivers the best value for both current and future production requirements.
