description

The TSM72 pilot gear pump adopts upgraded reinforced alloy gear pair and thickened high-rigidity aluminum alloy integrated pump body, specially customized for the variable load working characteristics of 2–3.5 ton enhanced mini excavators with alternating light and heavy loads. On the basis of retaining ultra-low pulsation mute technology, it improves gear meshing strength and structural anti-fatigue performance, realizing stable output under intermittent micro heavy-load conditions such as gravel shoveling and thin soil excavation. Optimized with medium-pressure dynamic pressure compensation structure, it effectively suppresses pressure drop and flow attenuation caused by load impact, maintaining stable pilot pressure output during frequent switching from fine trimming to light earthwork operation. Equipped with upgraded high-temperature and wear-resistant composite oil seal and enhanced anti-leakage structure, it adapts to long-time variable load cycle operation of enhanced micro excavators, avoiding internal leakage and pressure loss caused by frequent heavy-load impact. With balanced mute effect and heavy-load stability, it retains the fine control advantage of micro-tonnage pumps while possessing durable heavy-load performance close to small-tonnage models.

advantages

  • Dual Balance of Mute & Heavy-Duty Performance: Inheriting the ultra-low pulsation mute technology of the TM series, it retains excellent fine control and low-noise advantages for urban fine construction. The upgraded reinforced structure greatly improves impact resistance, supporting stable operation of small-scale earthwork and gravel heavy-load scenarios.
  • Medium-Pressure Dynamic Compensation, No Attenuation in Variable Load: Equipped with exclusive medium-pressure adaptive pressure compensation system, it actively adjusts pressure and flow according to load changes. No jitter or lag during switching from fine trimming to heavy-load excavation, ensuring consistent and stable control performance in full working conditions.
  • Reinforced Anti-Fatigue Structure, Longer Service Life: Thickened pump body and high-strength gear pair effectively resist fatigue loss caused by long-term alternating light and heavy load operation. The overall structural stability is far better than ordinary ultra-micro pumps, reducing long-term wear and failure probability.
  • Enhanced Anti-Leakage Seal, Adaptable to Complex Working Conditions: Upgraded high-temperature and wear-resistant composite oil seal solves the common faults of ordinary micro pumps such as easy internal leakage and pressure drop under intermittent heavy impact load, adapting to diverse complex construction scenarios of enhanced micro excavators.

FAQ

  • Q1: Full-series gradient positioning of TSM72?
  • A: TM40VD(0.8–2t ultra-micro mute precision,22–26bar) > TSM72(2–3.5t micro heavy-duty balance,26–30bar) > SG025(1–3t mute precision,24–28bar) > SG02(1.5–4t light&medium load) > SG04(4–6t medium heavy load) > SG08(6–8t rock heavy load) > SG20(8–12t industrial ultra-heavy load) > SBS120(12–16t medium high-pressure heavy load) > SBS140(16–20t ultra-high pressure extreme heavy load). TSM72 is the exclusive balanced mute & heavy-duty transition model for enhanced micro excavators.
  • Q2: Which excavators is TSM72 suitable for?
  • A: TSM72 is exclusively developed for 2–3.5 ton upgraded/enhanced mini excavators, matching medium-displacement reinforced main pumps. It is specially suitable for micro excavators that need to switch frequently between indoor fine renovation and outdoor small-scale earthwork & gravel operation.
  • Q3: What core problems can TSM72 solve?
  • A: It solves the bottleneck problems of enhanced micro excavators: insufficient pilot power during light earthwork operation, obvious performance attenuation after long-time gravel construction, unsmooth compound actions in variable-load switching, and loud operation noise in urban working scenarios.
  • Q4: Why choose TSM72 instead of TM40VD/SG025 for 2–3.5t micro excavators?
  • A: TM40VD is only suitable for pure light-load fine operation with insufficient heavy-load resistance; SG025 has excessive pressure and flow margin for 2–3.5t equipment, leading to stiff operation and poor fine control. TSM72 adopts transition-grade medium-pressure calibration, balancing mute precision and heavy-load stability, which is the most matching model for 2–3.5t variable-load enhanced micro excavators.
  • Q5: Daily maintenance specification for TSM72?
  • A: Keep the hydraulic oil clean and replace filter elements regularly to protect reinforced gear pairs. Avoid long-term continuous overload operation beyond micro-tonnage limit. Regularly check the medium-pressure sealing components to ensure stable variable-load pressure output and maintain long-term balanced mute and heavy-duty performance.
