Roquet 1L05DE10R-SMPDual stage combination front-end pumpThe power core of a multi circuit hydraulic system

The hydraulic system of equipment such as combine harvesters and large loaders often requires "multi circuit independent power" - for example, the lifting of the cutting table and the unloading of the grain tank need to operate simultaneously, and traditional single pumps are prone to "power competition". Roquet 1L05DE10R-SMP, as the front-end module of the LQ series two-stage pump (L0+L0), with a displacement of 3.3cm ³/rev and an inter stage torque design of 25Nm, can be combined with the back-end pump to achieve "dual flow independent output", becoming an ideal power solution for multi loop systems.

2、 Roquet 1L05DE10R-SMP solves the problem of flow distribution in multi loop equipment

The core pain point of multi circuit hydraulic equipment is that "a single pump cannot meet the flow requirements of multiple systems". For example, when a combine harvester lifts and lowers the header, the unloading speed of the grain tank will decrease. However, the two-stage combination design of Roquet 1L05DE10R-SMP can solve this problem from three aspects:

1. Independent traffic outputThe 5L/min flow rate adjustable platform lifting system of 1L05DE10R-SMP and the 3L/min flow rate grain tank unloading system of the back-end pump are independently controlled and do not interfere with each other. Taking a certain brand of combine harvester as an example, the lifting time of the cutting table after combination is maintained for 8 seconds, and the unloading time of the grain tank is maintained for 12 seconds, resulting in a 30% increase in operating efficiency and avoiding the problem of traditional single pump "neglecting one thing and losing the other".

2. Stable power transmission between stagesThe "inter stage torque" of a two-stage pump is crucial - traditional combination pumps often experience fluctuations in the speed of the rear end pump due to torque mismatch. However, the E-shaft of Roquet 1L05DE10R-SMP is connected to the L-shaped shaft of the rear end through a middle cover kit, with an inter stage torque of 25Nm, which ensures that the speed of the rear end pump is synchronized with the front end (error<2%) and avoids flow fluctuations. Meanwhile, the middle cover kit is equipped with a built-in seal to prevent oil leakage and enhance system reliability.

3. Flexible combination adaptation1L05DE10R-SMP can be paired with back-end pumps of different displacements (such as 1L01, 5DL26R, 1L07, 5DL26R) to meet the flow requirements of different equipment. For example, a large loader requires a dual circuit of "steering+lifting", which can be paired with 1L07, 5DL26R rear end pumps (7.5L/min) to achieve a combination of "front end 5L/min steering+rear end 7.5L/min lifting" and adapt to the operating rhythm of the loader.

3、 Procurement and maintenance advantages of Roquet 1L05DE10R-SMP

For equipment procurement managers, the "modular" design of Roquet 1L05DE10R-SMP can reduce stocking costs - there is no need to stock complete two-stage pumps, only front-end modules, back-end pumps, and intermediate cover kits need to be separately stocked and combined as needed, reducing inventory costs by 40%. At the same time, Roquet provides joint guarantee services, and its distribution network in 35 countries can quickly supply goods, avoiding equipment downtime caused by spare parts shortages.

For maintenance engineers, the standardized design of 1L05DE10R-SMP facilitates troubleshooting: if the front-end of the two-stage pump fails, only the front-end module needs to be replaced without disassembling the back-end pump, reducing maintenance time from 4 hours to 1.5 hours. In addition, Roquet provides a detailed assembly manual, indicating key parameters such as the tightening torque of the middle cover screws (30-40Nm) and the shaft fit clearance (0.05mm), to reduce the difficulty of on-site operations.

As the core component of the Roquet LQ series two-stage pump, 1L05DE10R-SMP continues the brand's reliability - all modules have passed fatigue testing (1000 hours of continuous operation) and noise testing (operating noise ≤ 68dB), with 99.9% factory testing ensuring performance meets standards. Whether it's purchasing new equipment or upgrading old systems, they are both high-quality choices for multi circuit hydraulic equipment.
