Product Description

BM3 series is a classic low speed high torque orbital hydraulic motor, featured integrated end face flow distribution structure. It can perfectly replace imported Eaton and Danfoss OMS series hydraulic motors, with full displacement options: 80,100,160,200,250,315,400 ml/r.
Integrated distributor and output shaft design, matched insert-tooth stator-rotor set and double roller bearings on both ends, delivering high pressure resistance, high volumetric efficiency and strong side load capacity. It owns low starting pressure, smooth reversing, stable operation at both high and low speed with low noise, outstanding short-time overload performance. Compact & lightweight design allows direct connection with load without reducer, simplifying hydraulic circuit and cutting equipment manufacturing cost.
Series & parallel circuit installation supported, rated continuous working pressure 11~14MPa, intermittent peak pressure up to 17MPa. Multiple mounting flanges, flat key/spline output shafts and port sizes optional, custom OEM service available. Widely applied to all kinds of low-speed heavy-duty transmission equipment as core power component for construction, agriculture, fishery, marine, plastic injection and mining lifting machinery.

Core Advantages

  1. Dual roller bearing heavy load structure
    Double thickened bearings at both ends, max side load up to 800kg, anti-eccentricity and anti-impact, ideal for heavy start-stop scenarios of travel and winch equipment.

    Integrated end-plate flow distribution, high efficiency & long service life
    Wear-resistant compensation distributor plate, volumetric efficiency ≥90%, low internal leakage, slight abrasion under long-term high pressure, service life extended by over 30%.

    Low starting pressure, stable low-speed operation without crawling
    Starting pressure as low as 0.5MPa, minimum stable speed 15r/min, smooth & quiet reversing, vibration-free operation under any flow rate.

    High back pressure resistance, support series & parallel synchronous drive
    Imported composite high-pressure oil seal withstands instantaneous back pressure up to 5MPa without extra charge valve; multiple motors run synchronously in series or parallel for multi-wheel and multi-roller machinery.

    Compact body, direct load connection without reducer
    Integrated cast steel housing with compact & lightweight design, direct flange connection to working mechanism, simplify hydraulic circuit and reduce equipment production cost.

    Multiple installation specifications, customizable OEM service
    Optional square/round flange, flat key/spline shaft, G1/2 & G3/4 ports; custom drain port, housing coating and special displacement available.

    1:1 interchangeable with imported OMS motors, cost-effective replacement
    Fully interchangeable with Eaton & Danfoss OMS motors in dimension, circuit, pressure and torque parameters, plug-and-play without frame or pipeline modification, greatly cut purchasing cost.

    Wide industry adaptability & stable performance in harsh environment
    Rated continuous pressure 11-14MPa, peak pressure 17MPa with strong short-time overload capacity; anti-rust housing and temperature-resistant seals work reliably for dusty, humid outdoor machinery.
