Baoding Langke Trading Co. Ltd

China‑based Baoding Langke Trading Co. Ltd lists 40 active products across four top categories: industrial pumps, agriculture equipment, compressors and hydraulic breakers. The catalogue includes a variety of pump types such as cantilever centrifugal pumps, pipeline hot‑water pumps, pulp pumps, submersible sewage pumps, single‑suction self‑priming pumps and vertical multistage centrifugal pumps, as well as vacuum water products and liquid‑ring vacuum pumps. In the compressor segment the company references the CBK and CBA2 models, while the hydraulic breaker line is noted without detailed model numbers. All items fall under the HS‑code families for pumps (generally 8421) and compressors (8422), which are the standard tariff headings used for these machines worldwide.

The supplier also records compliance references such as the GB 6245‑2006 fire‑pump standard and holds an OHSAS 18001:2007 occupational health‑safety certification. No further corporate history, employee numbers or revenue figures are provided; the focus is strictly on the listed product types and the applicable trade classifications.

The catalogue’s centrifugal pumps cover designs from single‑stage, single‑suction units to vertical multistage configurations. In the global market these pumps are typically offered in flow ranges of 5 - 500 m³/h, pressures up to 30 bar, and are constructed from cast iron, stainless steel or ductile iron to meet ISO 5199 performance classes. Self‑priming pumps are commonly rated for NPSH ≤ 3 m and feature automatic priming mechanisms that meet IEC 60534‑2‑1. Submersible sewage pumps listed under the QW line usually handle solids up to 20 mm, carry an IP68 protection rating and conform to IEC 60335‑2‑6 for wastewater applications. Liquid‑ring vacuum pumps such as the CDF model are oil‑free, with capacities from 500 to 2 000 m³/h and are evaluated against ISO 1217 for vacuum performance. Compressors like the CBK and CBA2 series are generally oil‑free rotary‑screw or piston types, delivering pressures of 8 - 12 bar and efficiencies above 85 % in accordance with ISO 8573‑1 air‑quality standards. Hydraulic breakers, while not detailed, are typically rated by impact energy (2 - 5 kJ) and meet ISO 11126 for safety and performance.
