Rocket 1L03DE10RSingle stage gear pump without pulley275 bar high pressure adaptation, power optimization for small and medium-sized hydraulic equipment

In the procurement and maintenance scenarios of small and medium-sized hydraulic equipment such as tractors, forklifts, and small loaders, equipment procurement managers and maintenance engineers are most concerned with the three core requirements of "pressure stability", "easy installation", and "strong durability". Roquet brand from Spain, with over half a century of accumulated hydraulic technology, has launched1L03DE10R gear pumpWith a continuous high-pressure output of 275 bar, standardized structural design, and wide temperature adaptability, it has become a product for small and medium-sized hydraulic systems, solving the industry pain points of insufficient power, cumbersome adaptation, and short service life of traditional pumps.

2、 Three core advantages to solve the pain points of small and medium-sized hydraulic equipment

1. High voltage stable output, solving the problem of insufficient powerTraditional small and medium-sized hydraulic pumps are prone to pressure fluctuations (± 10 bar) when the pressure is above 250 bar, which can cause equipment to malfunction. Roquet 1L03DE10R adopts a hydraulic balance design, which reduces radial force by 40% by optimizing gear tooth profile and pressure balance groove. The fluctuation under continuous pressure of 275 bar is only ± 5 bar. In a forklift renovation project in a logistics park, after replacing the original pump body, the lifting speed of the forklift remained stable at 0.5m/s, and there was no falling phenomenon in the suspension of heavy objects, resulting in a 25% increase in operational efficiency.

2. Standardized structure reduces installation and maintenance costsMaintenance engineers often face the dilemma of "replacing old pumps with modified equipment bases", but the E-shaft, 10 front end cover, and R-port of 1L03DE10R all follow international standards and can directly replace products of the same level from brands such as Rexroth and Parker. In the maintenance of hydraulic suspension pumps for tractors at a certain agricultural machinery station, the installation time was shortened from 8 hours to 2 hours, and the downtime loss was reduced by 60%; Roquet also provides specialized spare parts kits (drive shafts, seals, etc.), eliminating the need for a complete replacement of the pump body and reducing maintenance costs by 70%.

3. Wide temperature adaptation+long lifespan, improving equipment attendance rateThe pump adopts automatic lateral adjustment technology, which can automatically compensate for gear wear clearance (0.02-0.05mm). After continuous operation for 5000 hours, the flow attenuation rate is only 3%, and the service life can reach more than 10000 hours. -The low-temperature adaptability of 20 ℃ solves the difficulty of starting equipment in winter in northern China, and the high-temperature tolerance of+80 ℃ can cope with the heat dissipation pressure of continuous operation in the workshop, maintaining stable performance in multiple environments and increasing equipment attendance by 30%.

3、 Typical application scenarios and installation and usage suggestions

Core application scenariosSuitable for small and medium-sized hydraulic equipment such as tractor hydraulic suspension systems, forklift lifting mechanisms, small loader steering systems, and machine tool hydraulic clamping devices. In the field of agriculture, it is suitable for tractors from brands such as Dongfanghong and John Deere; In the industrial field, it can be used for power upgrades and maintenance replacements of forklifts from brands such as Heli and Hangcha.

Installation and usage suggestionsPriority should be given to using elastic couplings as the driving method to absorb radial/axial vibrations of 0.3-0.4mm and avoid damage to the pump body caused by motor vibrations; ② The diameter of the suction pipe should be ≥ 16mm to ensure a pressure drop of<0.3bar and prevent cavitation; ③ Before use, check the cleanliness of the oil. If it does not meet the ISO 4406 19/16 standard, replace the oil and filter element; ④ After installation, it is necessary to confirm the rotation direction (clockwise, observed from the drive shaft end) to avoid damage to the pump body caused by reverse operation.

As a Spanish hydraulic brand, Roquet conducts 99.9% factory testing on 1L03DE10R, and the core components (pump shaft, castings) are independently produced with guaranteed quality. Whether it is the "cost performance balance" during equipment procurement or the "quick adaptation" during maintenance, 1L03DE10R is a cost-effective choice for small and medium-sized hydraulic systems and has been widely adopted by industrial customers in 35 countries.
