Choosing the Right Pump for Smooth and Consistent Dough, Paste, and Liquid Transfer

When we talk about food processing, smooth and consistent dough, paste, and liquid transfer are essential to maintain the quality of products and the process. From bakery doughs to thick sauces and fragile liquids, the need is to transfer these materials smoothly yet efficiently, without disrupting their texture or violating hygiene standards.

This is where selecting the proper pump truly matters. Installing a pump engineered specifically for food use enhances reliability, minimizes downtime, and keeps your production line running at maximum efficiency.

Here are the most important factors to consider when choosing a pump for this use, and why Fristam's FKL Positive Displacement Pump is a reliable choice.

The Challenge of Handling Dough, Pastes, and Liquids

Transporting materials such as dough or heavy pastes is different from pumping water or thin liquids. These are heavy, viscous, and shear force-sensitive materials. The improper equipment can lead to:

• Broken or damaged product structure
• Excessive heat
• Product sticking within the pump, causing blockages
• Inefficient and recurrent cleaning cycles
• Unnecessary downtime and heavy maintenance expense

For the food processing industry, these issues can have a direct effect on quality, consistency, and profitability. If you're a bakery transporting dough, a dairy mixing creamy materials, or a beverage company working with liquids, you require a pump that suits your material's viscosity and sensitivity.

Types of Pumps Typically Used

In the food processing industry, there are a number of pump types that are utilised based on the application:

• Liquid transfer pumps: A perfect choice for transferring thin, free-flowing liquids such as milk, water, or juice.
• Rotary lobe pumps: A first choice for pumping viscous and shear-sensitive materials due to their mild but intense pumping action.
• Centrifugal pumps: Suited for low-viscosity liquids where large flow rates are required.
• Positive displacement pumps: Able to transport high-viscosity doughs, pastes, and liquids without causing harm to them.

When you’re looking for the best pump for transferring dough in a bakery or moving sticky pastes, a positive displacement pump like the Fristam FKL series is your ideal choice.

Why Positive Displacement Pumps Are Ideal

Positive displacement pumps transfer a definite quantity of product per stroke and are therefore excellent for viscous and sensitive materials. They run slowly and generate minimal shear, retaining the texture and integrity of food products.

For uses requiring both cleanliness and wear life, Fristam's FKL Positive Displacement Pump is an industry-leading performer.
