KENNESAW, Ga., January 26, 2026 – Unibloc® Hygienic Technologies (UHT), a manufacturer of hygienic pumps and flow control products, announces a new line of patent-pending twin screw pumps that are easier to maintain, are more sanitary, and reassemble faster than any other hygienic twin screw pump on the market. It is ideal for applications in the food, cosmetics, personal care products, industrial, and pharmaceutical industries.
Like other twin screw pumps, Unibloc Twin Screw pumps provide a smooth, non-pulsating flow that minimizes shear stress, preserving the integrity of high viscosity, shear-sensitive products such as dairy products, emulsions, fruit purees, soups, creams, gels, and serums. They are designed to generate more pressure than some other pump designs, making them ideal for long pipe runs, vertical lifts, and highly viscous products. They provide effective cleaning in place because they can operate athigh RPM.
Unlike other twin screw pumps, the Unibloc Twin Screw pumps provide a variety of advantages that make it easier to operate, offer more performance, are faster to clean, and provide a lower Total Cost of Ownership:
- It is designed for simplicity, with fewer parts, identical drive and lay screw shafts, one-way reassembly, and other innovations that make cleaning much faster than the hours required for other twin screw pumps.
- It is the only twin screw pump that provides external access to make timing adjustments (patent pending), allowing rapid 5-minute adjustments without the time-consuming process of disassembling the entire oil housing. Other twin screw pumps require the user to remove the housing, exposing the surrounding workspace and food stream to contamination and risking slippery oil spills.
- The entire oil reservoir design, also patent-pending, delivers better oil circulation, providing superior heat dissipation and enhanced bearing protection to extend bearing life and reduce the risk of overheating.
- It offers a patent-pending front-loaded seal design that simplifies replacement and decreases the chance of seal failures.
- Their modular designs make it easier to upgrade to other models.
- Their bi-directional flow enables complete emptying, minimizing product waste and ensuring thorough cleaning between batches.
- The pumps are capable of dual-duty design – a single pump for processing at low speeds or effective CIP at higher speeds.
UHT becomes the only leading manufacturer of all four primary hygienic pump technologies.
It has long been a challenge for processors to select the right pump typefor an application. While customers seek guidance from pump manufacturers, they worry about potential bias, unsure if they’re getting the best technology or just what the manufacturer happens to sell.
As the only leading pump manufacturer to offer all four primary hygienic pump technologies, UHT application engineers can provide unbiased recommendations for the most appropriate pump technology:
- Lobe pumps
- Gear pumps
- AODD (air-operated double-diaphragm) pumps
- Twin screw pumps
“Our customers are experts in their processes but not always experts in the fluid dynamics that determine the best pump technology they need to transfer their products,” explains UHT CEO Chris Stevens. “Now, with the addition of the Twin Screw pump family, we can recommend the most effective of the four primary pump technologies for a customer’s application, while others have to make compromises due to a more limited product offering.”
Unibloc Twin Screw pumps offer better productivity, and lower Total Cost of Ownership.
The Unibloc Twin Screw pumps offer gentle handling of fluids with viscosities up to 1,000,000 cP and solid particles up to 45 mm. The family of four pumps has flow capacities from 200 to 1,200 gallons (757 to 4542 liters) per minute with volumetric efficiency greater than 90%. The pumps can operate at temperatures up to 248°F (120°C) and system pressures of 360 psi (24.8 bar) to enable their use with a wide range of products.
| Screw Diameter | Ports | PSI (Bar) | RPM | Flow per Minute |
|---|---|---|---|---|
| 3-inch (080 mm) | 3-inch | 360 psi (24.8 bar) | 3600 | 200 gallons/min (757 liters) |
| 4-inch (100 mm) | 3-inch | 360 psi (24.8 bar) | 3000 | 300 gallons/min (1135 l/min) |
| 5-inch (130 mm) * | 5-inch | 360 psi (24.8 bar) | 1800 | 380 gallons/min (1438 l/min) |
| 7.5-inch (190 mm)* | 8-inch | 360 psi (24.8 bar) | 1800 | 1200 gallons/min (4542 l/min) |
The Twin Screw pumps meet 3A sanitary standards and support clean-in-place (CIP) processes, with significant reductions in maintenance costs and pump downtime. Operating speeds up to 3,600 RPM for increased productivity with reverse pumping capability to minimize product waste.
