OEM External Gear Pump 31.5cc CBHZ-F31.5ALH6L For Concrete Mixer Truck
External Gear Pump Description
Our CBHZ-F31.5ALHL hydraulic gear pump features a 31.5 ml/r displacement, a rated pressure of 20 MPa (peak 25 MPa), a wide speed range of 600-3000 r/min, and a high volumetric efficiency of ≥93%. It is specifically designed for material handling equipment such as forklifts (e.g., Heli H2000 series 3-3.5 ton diesel forklifts). It boasts high pressure durability, low noise, stable flow, and strong installation compatibility, making it a reliable and cost-effective choice for the hydraulic systems of medium-duty forklifts and industrial vehicles.
Our External Gear Pumps are meticulously crafted from high-quality aluminum or cast iron, featuring a compact structure, lightweight construction, corrosion resistance, and excellent self-priming performance, making them suitable for medium- and high-pressure hydraulic systems.
Their range covers various displacements (from a few cc to hundreds of cc), fully compatible with internationally renowned brands such as Parker and Rexroth (e.g., PGP and GP series alternatives), allowing direct replacement of original pumps without system modifications.
Runhe Hydraulics specializes in the production and export of hydraulic cylinders, hydraulic gear pumps, hydraulic gear motors, and spare parts, committed to providing top-tier quality and after-sales service. Our highly competitive prices and superior quality have earned us a growing number of partners.
