・Heavy-duty A10VN41ED73/52 variable piston fan pump tailor-made for XCMG XE700, Parker compatible, perfectly matched with original fan motor
A10VN41ED73/52 hydraulic fan pump is custom designed for XCMG XE700 large mining excavator. It provides adjustable hydraulic flow to matched fan motor. Reliable variable hydraulic power supply ensures the cooling fan can automatically adjust speed under heavy-load rock excavation and long-hour continuous operation, preventing engine overheating.
・Precision hardened piston & cylinder block assembly, stable variable output and fast ED73 electro-hydraulic response
Alloy steel piston and cylinder block assembly adopts precision grinding and surface hardening process. ED73 electro-hydraulic controller can quickly adjust pump displacement with pressure change. Volumetric efficiency is kept at high level to guarantee stable adjustable hydraulic oil supply for cooling circuit.
・High-rigidity cast iron housing with stress relief treatment, excellent anti-vibration and pressure impact resistance
Cast iron housing after stress relief annealing eliminates internal residual stress. It can resist continuous heavy vibration and high pressure impact in quarry and open-pit mining sites. The housing is not easy to deform, slowing down wear of internal piston, valve plate and bearing components and extending service life.

FAQ 

Q1: What is the core advantage of ED73 electro-hydraulic control for this A10VN41ED73/52 fan pump?
A1: ED73 electro-hydraulic control supports proportional adjustment of pump displacement, faster response to coolant temperature fluctuation, more precise fan speed control compared with conventional pressure-flow control pumps.

Q2: Can this A10VN41ED73/52 fan pump fit XCMG XE690 or XE750?
A2: This pump is specially developed for XE700. XE690 and XE750 adopt different pump displacement and installation interface, not interchangeable. Verify part number before ordering.

Q3: What hydraulic oil cleanliness standard should be kept after pump installation?
A3: Maintain hydraulic oil cleanliness above NAS 6 grade. Impurities in oil will scratch the piston and valve plate, leading to early internal leakage and pump failure.

Q4: What causes ED73 control delay after pump installation?
A4: Main causes: air trapped inside electro-hydraulic control cavity, insufficient control pressure, contaminated control oil or ED73 valve assembly wear. Bleed air and clean control oil circuit first.

Q5: What inspection items should be done during routine maintenance of this fan pump?
A5: Check ED73 controller signal response, seal leakage and pump outlet pressure every 2000 working hours. Replace hydraulic oil and filter elements regularly to protect internal friction pairs.
