Unibloc Pumps FAQ

What are Unibloc pumps?

Unibloc manufactures sanitary positive displacement pumps and other fluid-handling equipment designed for hygienic and demanding process applications. Their pumps are commonly used where cleanability, gentle product handling, reliability, and process efficiency are important.

What types of pumps does Unibloc manufacture?

Unibloc offers rotary lobe pumps, gear pumps, sanitary pumps, drum pumps, and other specialized fluid-handling solutions designed for hygienic and industrial processing applications.

What industries use Unibloc pumps?

Unibloc pumps are commonly used in food and beverage processing, dairy production, pharmaceutical manufacturing, cosmetics, personal care products, biotechnology, chemical processing, and other hygienic applications.

What is a rotary lobe pump?

A rotary lobe pump is a positive displacement pump that uses rotating lobes to move fluid through the pump. This design provides consistent flow and gentle product handling, making it well suited for many sanitary and high-viscosity applications.

What are Unibloc pumps commonly used for?

Common applications include transferring dairy products, sauces, syrups, oils, creams, beverages, personal care products, pharmaceuticals, chemicals, and other process fluids.

Can Unibloc pumps handle viscous products?

Yes. Positive displacement pump technology is particularly effective for moving high-viscosity products that may be difficult for conventional centrifugal pumps to handle efficiently.

Can Unibloc pumps handle shear-sensitive products?

Yes. Properly selected Unibloc pumps can provide gentle product handling for applications where excessive shear could affect texture, consistency, or product quality.

Are Unibloc pumps suitable for sanitary processing?

Yes. Many Unibloc pumps are specifically designed for sanitary and hygienic applications where cleanability, product integrity, and contamination control are critical.

Can Unibloc pumps be used with clean-in-place systems?

Depending on the pump and system configuration, Unibloc pumps can be incorporated into clean-in-place, or CIP, processes that allow equipment and piping to be cleaned without extensive disassembly.

How do I know which Unibloc pump is right for my application?

Proper pump selection depends on required flow, discharge pressure, product viscosity, temperature, solids content, shear sensitivity, sanitary requirements, and cleaning procedures. Evaluating the complete process helps determine the appropriate pump configuration.

What are signs that a Unibloc pump may need service?

Common warning signs include reduced flow, inconsistent pressure, unusual noise, excessive vibration, product leakage, increased operating temperatures, or declining process performance.

What maintenance do Unibloc pumps require?

Routine maintenance may include inspecting seals, bearings, rotors, gears, lubrication where applicable, and other wear components. Sanitary applications may also require regular inspection of product-contact components to maintain proper hygienic operation.

Can Unibloc pumps be repaired or rebuilt?

In many cases, yes. Worn seals, bearings, rotors, gears, and other components may be repaired or replaced to restore pump performance and extend equipment life.

Does Industrial Air Services provide Unibloc pump service and support?

Yes. Industrial Air Services provides Unibloc pump support, troubleshooting, preventative maintenance, repairs, replacement equipment, parts assistance, and application support throughout Nashville, Murfreesboro, Franklin, Clarksville, Knoxville, Chattanooga, Bowling Green, and surrounding areas.

Can Industrial Air Services help select a replacement Unibloc pump?

Absolutely. Industrial Air Services can evaluate your product characteristics, required flow and pressure, viscosity, sanitary requirements, cleaning procedures, and operating conditions to help determine the appropriate Unibloc pumping solution.
