Rexroth Excavator Hydraulic Gear Pump PC30-7 9t
Rexroth Excavator Hydraulic Gear Pump PC30-7 9t Pilot Pump Construction Machinery Parts
Products Description
The PC30-7(9T) Gear Pump is a precision-engineered hydraulic component designed specifically for PC30-7 (9-ton class) mini excavators. Built for durability, high-pressure performance, and seamless compatibility, this gear pump optimizes hydraulic system efficiency in demanding construction, mining, and landscaping applications. Whether you're digging, lifting, or loading, trust our gear pump to deliver consistent power and reliability.
Features
High-Pressure Capability: Delivers stable flow under extreme loads, with a rated pressure of 25 MPa (3,626 psi) and peak pressure up to 28 MPa (4,061 psi).
Wear-Resistant Design: Helical gears made of alloy steel undergo surface hardening (HRC 58+), reducing friction and extending service life by 30% vs. standard pumps.
Perfect Compatibility: Direct replacement for OEM PC30-7 (9T) models; no modification required for installation.
Low Noise Operation: Optimized gear meshing design minimizes vibration, operating at ≤75 dB(A) at 2,000 rpm.
Quick Installation: Pre-lubricated and calibrated for plug-and-play replacement, reducing downtime by 50%.
