Unibloc Hygienic Positive Displacement Pumps FAQ
What are Unibloc hygienic positive displacement pumps used for?
Unibloc pumps transfer ingredients and finished products in hygienic processing. Applications include food, beverage, dairy, personal care, and other duties requiring suitable cleanability and product handling.
Which rotary pump designs does Unibloc offer?
Unibloc lists rotary lobe, gear, and twin-screw products. Compare the specific technology with the process requirements rather than assuming all hygienic positive displacement designs perform identically.
How does a Unibloc rotary lobe pump work?
Timed rotors carry liquid around the pump casing toward the discharge. The lobes do not normally contact each other, and external timing gears coordinate their rotation.
How do rotary lobe and circumferential piston pumps compare?
Both are rotary positive displacement technologies, but rotor geometry and sealing paths differ. Confirm the actual manufacturer's model and pump design when comparing capacity, pressure, and cleanability.
What is Unibloc QuickStrip design?
QuickStrip is an access and disassembly feature offered on selected Unibloc products. Confirm the exact pump's construction and maintenance procedure rather than assuming it applies to every configuration.
Can Unibloc pumps transfer thick ingredients?
A suitable configuration can handle viscous material. Required torque, inlet filling, operating speed, and product temperature should be considered alongside the requested flow and pressure.
Can a lobe pump handle products with pieces?
Particle passage and product damage depend on rotor geometry, clearances, speed, and particle properties. Provide maximum piece size and quality expectations when evaluating a suitable model.
Why is shear sensitivity important in pump selection?
Some products change texture, viscosity, or structure when exposed to mechanical stress. Evaluate the pump and piping together, particularly where product repeatedly recirculates through the process.
What materials matter in hygienic pump construction?
Product-contact metals, elastomers, seal faces, and surface finishes must suit the product and cleaning procedure. Material documentation should match the exact configuration supplied.
Can Unibloc pumps be cleaned without disassembly?
Some configurations support clean-in-place procedures, while others may require disassembly for the intended process. Confirm the cleaning method and validate it for the product and installation.
How do gear pumps differ from lobe pumps?
Gear pumps carry liquid between gear teeth and the casing. Lobe pumps use timed lobes, creating different passage characteristics, slip behavior, and suitability for delicate particles.
How do I select a hygienic positive displacement pump?
Provide flow, pressure, viscosity, temperature, particle characteristics, and sanitation requirements. Include the feed-vessel arrangement and piping so the proposed pump can be checked for adequate inlet supply.
Why is pressure protection needed?
A restricted discharge can cause excessive pressure in a positive displacement system. The protective arrangement must suit the pump, downstream components, product, and expected operating scenarios.
What maintenance should be planned for Unibloc pumps?
Inspect seals, rotors or gears, bearings, and drive components according to the manual. Verify clearances, correct reassembly, and sanitation before returning product-contact equipment to service.
Can an existing hygienic pump be replaced with Unibloc equipment?
A replacement requires comparison of duty, product handling, materials, connection dimensions, footprint, and cleaning arrangements. Review the actual pump technology rather than relying on the website category alone.
