Product Description Detailed Photos Pressure Ripple and Noise AnalysisThe traditional designs of high-pressure gear pumps have a tendency to trap and compress fluid between the gear teeth, leading to several adverse effects:1. Sudden and sharp increases in pressure, leading to instability.2. Noticeable noise, especially when operating at speeds above 1500rpm.Innovatively, the helical pump design achieves a crucial engineering milestone:1. Complete elimination of trapped and compressed oil between the gear teeth;2. No compromises in the selection or treatment of materials, ensuring robust performance.The benefits are clear and plenteous:1. Gentle and smooth transitions in pressure growth, promoting stability.2. Superior efficiency, maximizing performance and energy use.3. Remarkably low noise levels, even at speeds up to 5000rpm, ensuring a quieter operation.Product ParametersModels availableHRP28,HRP33,HRP38,HRP47,HRP55,HRP72FlangesGoup1,Group2 (European, German, BKT, SAE-A), Group3 (European, SAE-B)ConnectionsGAS-SAE3/4" 3000PSI-FL 4HOLES M6 SU Dia40 DN20Installation positionExternal, underoilShaft rotationClockwise (standard)Shaft speedFrom 700 to 3600Rpm (for GR72 to 2200rpm)Displacements-FlowsFrom 4 up to 200cm3, from 6L/min up to 300L/min (at 1500 rpm)Operating PressureContinuous 240barCycle ON/OFF:250barPeak:280barInlet Pressure0.8~2barSealsNBR,FKMNoisefrom 52 up to 63dB(A) at 2950rpm-Value based on ISO4412 test procedureFlangesCast IronPump body (standard)Extruded aluminium alloyScrewCase hardened grinded steelBASIC DESIGNExternal gear pumps exemplify the zenith of hydraulic innovation, revered by engineers and designers globally as the ultimate hydraulic solution. These extraordinary devices are lauded for their versatility, exceptional durability, and significant lifespan, consistently chosen by industry leaders. Engineered with simplicity at their core, these pumps promise low initial and maintenance costs. Our pumps fuse traditional design with cutting-edge technology, benefiting from extensive research, expert craftsmanship, and advanced materials. Each unit undergoes rigorous testing, ensuring only the finest quality is delivered to our clients.Our pumps thrive even in the harshest environments, offering substantial hydraulic power effortlessly. SJ Technology gear pumps are distinguished by their outstanding hydraulic, mechanical, and volumetric efficiency, along with their reduced noise profile and compact design, making them the optimal choice for a variety of applications. Continuing our tradition of innovation, SJ Technology presents the pioneering GPM series with models such as 0.5U, 1P, GPM1.0, GPM2.0, and GPM3.0. These pumps are crafted for versatility, serving industries including industrial, mobile, marine, and aerospace, providing a customized solution for every need. Typically engineered with precision, these gear pumps consist of a gear pair supported by aluminum bushes, a robust body, securing flange, and cover. The driving gear's shaft extends beyond the flange, fitted with a twin-lip seal ring ensuring optimal sealing and dust protection. An elastic ring secures the seal. The pump body, made from a special high-resistance aluminum alloy via extrusion, is complemented by a flange and cover made from spheroidal cast iron, designed to retain integrity under constant and variable high-pressure conditions. Our gears, crafted from high-quality steel, undergo detailed grinding and fine finishing, ensuring smooth surfaces that reduce pulsations and noise during operation. The bushings, constructed from a specialized low-friction, high-resistance aluminum alloy, are die-cast and equipped with anti-friction DU bearings, ensuring smooth and efficient performance. Innovative compensation zones within the bushings, insulated by specially designed anti-extrusion seals, allow for free axial and radial movement. This adaptability to operational pressure significantly reduces internal leakage, optimizing pump performance and ensuring the ideal lubrication of moving components.Product ApplicationCompany ProfileCertificationsPackaging & ShippingFAQ1.Are you trading company or manufacturer ?We are factory since 1990.2.What is your sample policy?We can supply the sample if we have ready parts in stock, but the customers have to pay the sample cost and the courier cost.3.Do you test all your goods before delivery?Yes, we have 100% test before delivery.4.How to guarantee the high quality?We have testing department to make sure quality of every product, appearance and pressure test are good.5.How about your delivery time?Generally, it will take 30 to 45 days after receiving your advance payment.
