References and verification sources
This page lists the public documents we consult when we check figures and answer technical questions. These are third-party sources, not our own material; every link points to the original publisher, we are not responsible for their content, and no partnership is implied.
Why we publish them: before placing an order you should be able to check the figures yourself instead of taking our word for it. Every row states how far we verified it - fetched successfully, link only, and PDFs whose body could not be read are all marked separately.
Note: the figures we publish come from two named sources. The FLUTEK ranges (K3V / K5V / K3VL pumps, M5X swing assemblies, FDNB travel drives) follow the FLUTEK English catalogue dated 2024-11-25; the K5V212, the K7V sizes and the further M5X / FTD sizes published in September 2026 follow the manufacturer's own published product data. Every model page names its source directly under the specification table, and the first row below is that manufacturer source. The remaining rows are public documents we use for cross-checking and further reading - they are third-party sources, not our material.

|---|---|---|
| Hydraulic pump, swing motor and travel drive product data Product data we publish · PNM FK Co., Ltd. | The manufacturer's own published matrix: main pump sizes with rated / peak pressure and maximum speed (K3V / K5V / K7V), the M5X swing motor classes, the FDNB / FTD travel drive interchange table and the manufacturer parts tables. The K5V212, K7V, M5X and FTD model pages and the /catalogue/ pages carry these figures, and each of those pages names this source next to the table. Only fact fields are reproduced - size, pressure, speed, part number, drawing position, quantity - never page text or images. Verification: Product data harvested 2026-09-29 from the manufacturer site: Manufacturer product data harvested for the FLUTEK China agent catalogue (part numbers, quantities, positions, dimensions, pressure/speed figures are facts of the product). | Open source |
| K3V / K5V series technical brochure (PDF) Pump & motor datasheets · Kawasaki technical brochure hosted by GS Global Resources | Technical brochure for the K3V and K5V swash-plate axial piston pump series. The displacement, pressure, speed and torque figures we publish for the models we stock are based on this series documentation.

| SY215C medium excavator specification page Machine specifications · SANY Group, official | SANY official product page for the SY215C. The SY215 is one of the machines most often fitted with the K3V112DTP, so checking the machine specification helps confirm the pump specification.
