Floating Side‑Plate Pressure Compensation Structure This CBHZ hydraulic gear pump adopts floating side‑plate design for automatic axial clearance compensation, maintaining high volumetric efficiency even under long‑term high‑pressure working cycles.

High Pressure Performance For Heavy‑Duty Conditions Rated working pressure up to 20 MPa, peak pressure reaches 25 MPa. Stable output within 600‑3000 r/min speed range, perfectly suited for forklift and material‑handling heavy‑load applications.

Full Compatibility For OEM Replacement Standard 2‑bolt diamond A‑type mount flange, multiple displacement options from 23 mL/r to 36 mL/r. Various shaft types, thread ports(BSPP/NPT) and rotation directions are available for direct drop‑in replacement.

Asymmetric Gear Tooth Profile, Low Noise & Long Service Life Specially optimized asymmetric gear set reduces gear meshing impact and operating noise. High‑strength internal core parts extend pump service life under continuous industrial operation.

Wide Compatibility Of Hydraulic Media Reliable operation with ISO VG32 / VG46 mineral hydraulic oil, working temperature range from ‑10℃ to +80℃, adapts to diverse global site working environments.

Ready‑to‑Ship & Customizable Configurations Standard CBHZ series gear pump models are in stock for fast delivery. Custom modifications on shaft, port and rotation can be processed to meet special equipment requirements.

Q1: What is the working pressure of the CBHZ series hydraulic gear pump?

A: The CBHZ gear pump features 20 MPa rated working pressure and 25 MPa peak pressure. It is designed for continuous heavy‑duty operation for forklifts and material‑handling equipment.

Q2: What displacements are available for CBHZ high pressure gear pump?

A: Available displacement ranges from 23 mL/r to 36 mL/r, including 23, 25, 26.5, 28.2, 30, 32 and 36 cc variants to fit different forklift hydraulic systems.

Q3: Can the CBHZ pump be used as a direct OEM replacement for forklift?

A: Yes. Standard 2‑bolt diamond A‑type mounting flange, multiple shaft styles, port options and rotation directions support drop‑in OEM replacement for most mainstream forklift models.

Q4: What is the speed range for CBHZ series gear pump?
