These positive displacement pumps deliver smooth, pulse-free flow ideal for metering, transfer, and processing applications across food, pharmaceutical, and personal care product operations. Key advantages include simple, rugged construction with few moving parts, self-priming capability that handles air entrainment, and moderate suction lift. Unlike centrifugal pumps that lose efficiency with viscous products, gear pumps maintain performance across diverse applications.Unibloc® Hygienic Technologies (UHT) gear pumps handle viscosities ranging from water-thin to highly viscous while maintaining accurate flow rates. Their compact footprint conserves valuable floor space, while their quiet operation improves the working environment. Unibloc gear pumps combine these inherent advantages with our commitment to easy maintenance and product safety. Whether you're transferring cooking oil, pumping chocolate, or handling pharmaceutical ingredients, our pumps are proven to outperform.How often do gear pumps need maintenance?Gear pumps require maintenance at a frequency based on operating conditions, product characteristics, and application demands. In hygienic processing environments, daily cleaning and sanitation are standard, with comprehensive preventive maintenance typically scheduled monthly or quarterly, depending on run hours and product abrasiveness.Unibloc® Hygienic Technologies gear pumps are designed to be the easiest gear pumps to service, reducing maintenance times. Our patented QuickStrip® technology allows technicians to quickly access pump components without tools. Minimal parts, easy-to-access seals, and an easy-to-clean design all cut maintenance time significantly.Regular inspection of gears, seals, and clearances prevents unexpected failures, and with Unibloc gear pumps, the inspections are straightforward and fast. The robust construction and fewer moving parts translate to longer periods between major overhauls. This reliability and ease of maintenance reduce total cost of ownership while maintaining the hygienic standards critical to your operation.What is the life expectancy of a gear pump, and why do gear pumps fail?Gear pumps typically deliver 3 to 7 years of reliable service, although properly maintained Unibloc® Hygienic Technologies pumps usually exceed these expectations significantly. Life expectancy depends on operating conditions, maintenance quality, and design robustness. Common failure modes include rotor wear from abrasive products, seal degradation from chemical exposure or temperature extremes, bearing failure from inadequate lubrication, and housing damage from improper maintenance or foreign material. Cavitation, running dry, and exceeding pressure ratings accelerate wear dramatically.Unibloc® gear pumps are engineered to combat these failure modes through superior design and materials. Our pump housings are machined from solid 316L stainless-steel, providing exceptional strength and wear resistance compared to cast alternatives. This robust construction resists damage during aggressive CIP procedures and daily sanitation. By addressing root causes of pump failure through intelligent engineering, Unibloc gear pumps deliver extended service life and reliable performance.Key Features:Ultra-hygienic designPrecision-built bearing housingCompact designSmooth, quiet operationQuickStrip® design for meticulous cleaningBearing Housing:Strongest precision-built in the industryAvailable in both 316L stainless steel and anodized aluminumSolid 316L stainless steel comprises every pump headCompact Design – Short/Stout Shafts:Remove refraction at high pressuresReinforced jacket shafts availableSpiral Cut Gears:Pulsation-free flowCompatible with servomechanical equipmentQuickStrip® Design:Tool-free access to pump head and sealsOne-way assembly ensures accuracyOptional front-loaded seal designSanitary Pump Application Solutions:Best for viscous materialVersatile Seal Mount (VSM) technologyOffered in industry-specific materials and designsRotor material options: stainless steel alloy, Polyflex® plastic metal detectable, DuraCore® compositeGear material alternatives: Teflon/Stainless, Teflon, various plastics
