Product Introduction
HMHDB270 hydraulic motor, standard Displacement 4000cm3/r. Rated Pressure 210bar, Rated Power 149KW. Heavy load bearing, the shaft can bear greater Side Load.
The HMHDB270 hydraulic motor is a high-performance, highly reliable hydraulic power unit suitable for a variety of applications requiring high-performance hydraulic power. Its exceptional performance, efficiency, and durability make it an ideal choice for heavy machinery and equipment.
HMHDB270: Heavy‑duty (HD) reinforced version of HMB270 fixed‑displacement low‑speed high‑torque radial piston motor. Reinforced shaft & bearing assembly for higher radial shaft load capacity, designed for severe marine, offshore, mining and heavy industrial drives.
HMHDB: HM = series; HD = Heavy‑Duty reinforced bearing/shaft; B = flange mounting
270: Frame size
Shaft options for HMHDB270:
P2: Heavy‑duty parallel key shaft
S5: Heavy‑duty BS3550 spline
Z5: Heavy‑duty DIN5480 spline
Valve assembly: FM3 / SM3 distributor valve group
Suffix V: Vertical‑mount version with elevated high‑level drain port (for shaft‑up installation)
‑ General heavy‑industry: large mixers, mills, material‑handling equipment
Independent drain line is mandatory. Case back‑pressure must be kept ≤ 3‑5 bar to prevent shaft‑seal failure.
Recommended fluid: mineral‑based hydraulic oil; system filtration ≤ 10 μm.
Common failure modes: distributor plate wear, high internal leakage, insufficient output torque.
Due to heavy‑duty shaft, do NOT interchange shaft components with standard HMB270.
