These positive displacement pumps offer smooth, pulse-free flow, ideal for dosing, transfer, and processing in food, pharmaceutical, and personal care operations. Main advantages include simple, robust construction with few moving parts, self-priming capability handling air entrainment and moderate suction lift. Unlike centrifugal pumps, which lose efficiency with viscous products, gear pumps maintain performance across diverse applications.Unibloc® Hygienic Technologies (UHT) gear pumps handle viscosities from very thin to very viscous, maintaining precise flow rates. Their compact size saves valuable space, while quiet operation improves the work environment. Unibloc gear pumps combine these inherent advantages with a commitment to easy maintenance and product safety. Whether transferring cooking oil, pumping chocolate, or handling pharmaceutical ingredients, these pumps have proven excellent performance.How often do gear pumps need maintenance?Gear pumps require maintenance at a frequency depending on operating conditions, product characteristics, and application demands. In hygienic processing environments, daily cleaning and sanitation are standard, and comprehensive preventive maintenance is typically scheduled monthly or quarterly, depending on operating hours and product abrasiveness.Unibloc® Hygienic Technologies gear pumps are designed to be the easiest gear pumps to maintain, reducing maintenance times. Our patented QuickStrip® technology allows technicians to quickly access pump components without tools. The minimal number of parts, easy-access seals, and easy-to-clean design significantly reduce maintenance time.Regular inspection of gears, seals, and clearances prevents unexpected failures, and with Unibloc gear pumps, inspections are simple and quick. The robust construction and fewer moving parts allow for longer intervals between overhauls. This reliability and ease of maintenance reduce total cost of ownership while maintaining essential hygiene standards for your operation.What is the lifespan of a gear pump and why do they fail?Gear pumps typically provide 3 to 7 years of reliable service when properly maintained. Unibloc® Hygienic Technologies pumps often exceed these expectations. Lifespan depends on operating conditions, maintenance quality, and design robustness. Common failures include rotor wear from abrasive products, seal degradation from chemical or extreme temperature exposure, bearing failure from inadequate lubrication, and housing damage from improper maintenance or foreign materials. Cavitation, dry running, and excessive pressure dramatically accelerate wear.Unibloc® gear pumps are designed to combat these failure modes through superior design and materials. Our pump housings are made 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 smart engineering, Unibloc gear pumps offer extended life and reliable performance.Technical Specifications / FeaturesUltra-hygienic designPrecision-built bearing housingCompact designSmooth and quiet operationQuickStrip® design for meticulous cleaningAvailable in 316L stainless steel and anodized aluminumSolid 316L stainless steel pump headsReinforced jacketed shafts availableSpiral cut gears for pulsation-free flowCompatible with servo equipmentTool-free access to pump head and sealsFront-loading seal design optionVersatile Seal Mount (VSM) technologyRotor and gear material options: stainless steel, Polyflex®, DuraCore®, Teflon, plastics
