SSY008314909 Pump end suction pipe assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

SSY008314909 Pump end suction pipe assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

This oil suction pipe assembly boasts strong adaptability and is specifically designed for connecting hydraulic pump oil suction lines. It is widely used in excavators, loaders, hydraulic power units, and other applications, and is compatible with hydraulic pumps from Sany and various heavy-duty machinery. The pipe ends feature a 45-degree bevel design, facilitating increased suction area and reduced suction resistance. The finished product is integrally molded, eliminating the need for on-site welding and ensuring convenient installation. It addresses the pain points of traditional oil suction pipes, such as air intake, detachment, and wear, and supports bulk purchasing and repair/replacement. Strictly adhering to the GB/T 17395-2021 industrial standard, it undergoes full-process testing to eliminate potential defects such as deformation and leakage. With surface anti-corrosion treatment, it is suitable for harsh working conditions such as outdoor environments, high temperatures, and dusty environments, balancing quality and cost-effectiveness to ensure stable and efficient operation of the oil suction system.

Core technical parameters:

– Model: SSY008314909 (Standardized model, can be directly replaced, compatible with original hydraulic pump suction system, eliminating mismatch)
– Material: High-quality 20# seamless steel pipe (compliant with GB/T 8163 standard, wall thickness ≥5mm, tensile strength ≥375MPa, resistant to negative pressure, and not easily deformed)
– Surface treatment: Phosphating treatment + external spraying of anti-corrosion paint (hot-dip galvanizing optional), salt spray test ≥1000 hours, rust-proof and wear-resistant, suitable for humid outdoor environments.
– Specifications and dimensions: Nominal diameter Φ32mm, total length approximately 620mm, special connector for pump end, 45° bevel at pipe end, dimensional error ±0.02mm, oil suction flow rate 1.2~1.3m/s.
– Pressure resistance (negative pressure resistance): Rated negative pressure resistance ≥0.1MPa, no flattening or leakage, 100% pressure test for each batch to ensure stable oil absorption.
– Applicable media: Hydraulic oil, lubricating oil and other conventional hydraulic media. It is oil-resistant and corrosion-resistant, avoiding media corrosion of pipelines and affecting oil suction effect.
– Applicable working conditions: -40℃~120℃, resistant to high and low temperatures and impact, suitable for various complex environments on engineering sites, and not easy to age.
– Core functions: hydraulic pump end suction and delivery, air intake and leakage prevention, impurity filtering, ensuring sufficient oil suction of the hydraulic pump, and protecting pump body components.
– Suitable scenarios: hydraulic pump suction for excavators/loaders, hydraulic station pump end suction pipeline, and hydraulic pump accessories for heavy machinery.
– Installation method: The pump end is connected with a special connector and bolted. No on-site processing is required. Installation and disassembly are convenient and maintenance is easy.

The SSY008314909 pump-end suction pipe assembly, with its precise specifications, excellent negative pressure resistance, and pump-end adaptability, has become an essential component of hydraulic pump suction systems in construction machinery.
