Import Bmp Hydraulic Orbital Motor — Buy in wholesale FOB from Supplier in China

Shijiazhuang Hanjiu Hydraulic Co., Ltd. offers the BMP hydraulic orbital motor as an economical-series gerotor drive unit built around shaft distribution flow technology. The design centres on a precision gerotor gear set that converts hydraulic pressure and flow into rotary mechanical output, with the supplier emphasising compact envelope dimensions and favourable power-to-weight ratio. Shaft seals are specified to withstand high working pressures, enabling motors to be plumbed in parallel or series arrangements within mobile hydraulic circuits. The source description frames this as a small-volume, economical type, suggesting targeting of cost-conscious equipment builders rather than premium industrial applications. Specific technical parameters, including nominal displacement, rated pressure, and output torque, are not provided in the available data and must be confirmed directly with the supplier.

The gerotor orbital motor principle relies on an internal gear set with cycloidal tooth engagement, where the inner rotor orbits eccentrically within a stationary outer ring. Standard industry practice for this motor class employs alloy steel rotors with surface hardening to 58-62 HRC, mating against high-phosphorus cast iron or alloy steel stators with compatible hardness differentials to balance wear resistance and scuffing prevention. The shaft distribution flow architecture referenced by Hanjiu typically routes fluid through the central shaft and distributor plate, offering manufacturing simplicity and robustness against contamination compared with more complex disc valve arrangements. Typical economical-series units in this displacement class operate with continuous pressure ratings of 15-20 MPa and achieve mechanical efficiencies of 80-88% at rated conditions, though buyers should request Hanjiu's certified performance maps rather than relying on generic figures. Fluid compatibility extends to mineral oil-based hydraulic fluids per ISO 6743-4 HM and HV categories, with synthetic or biodegradable alternatives requiring explicit seal compatibility confirmation.

The supplier identifies brush cutters, mowers, harvesting equipment, forestry equipment, and turf equipment as primary applications, all characterised by intermittent duty cycles, space constraints, and exposure to vibration and contamination. Target buyers include agricultural machinery OEMs, compact equipment rental fleets, and aftermarket service providers seeking direct replacements. For procurement planning, critical compatibility factors include shaft diameter and keyway configuration, pilot diameter and mounting bolt pattern, port orientation relative to mounting surface, and whether the motor is furnished with a standard or optional cross-over relief valve. The Shijiazhuang production base sits approximately 270 km from Tianjin Port, a factor to incorporate into inland logistics costing.

Shijiazhuang Hanjiu Hydraulic Co., Ltd. operates from premises in Shijiazhuang, Hebei Province, with postal address 050000. The supplier's platform trust tier is listed as harbor, representing entry-level verification without advanced audit or inspection disclosure. No response rate data is available (recorded at 0.00%), meaning buyers lack statistical guidance on communication reliability through platform channels. The profile contains no information on year of establishment, production scale, R and D capability, or ownership structure. Prospective buyers should conduct independent due diligence, including direct verification of business registration with Hebei authorities and request for factory audit reports if order value justifies the expense.

The company positions itself as a source for BMP series hydraulic orbital motors with emphasis on economical pricing. No certifications, patent holdings, or OEM partnerships are mentioned in the source material. The absence of disclosed client references, export volume data, or aftermarket support infrastructure means buyers must probe these areas during negotiation. The Hebei location offers potential supply chain access to steel casting, machining, and heat treatment subcontractors common to the region's machinery manufacturing cluster, though this does not guarantee in-house manufacturing depth. Buyers should clarify whether Hanjiu manufactures gerotor sets in-house or sources them, as this affects quality control traceability and technical support capability.
