Manufacturer reference

Every size the factory publishes, and the parts lists behind them

18 main pump sizes (K3V / K5V / K7V), 4 swing motor classes and the travel drive cross-reference - published by the manufacturer (PNM FK) and reproduced here so you can check a number or a size before you write to us. Where we have a full model page for the unit, the size is linked to it.

Main pumps — size range and series limits

One row per published size. Pressure limits are given per series (rated / peak); the speed column is the maximum continuous speed for that size.

Travel drives — cross-reference

Left to right: the tonnage class, the FLUTEK unit number, and the equivalent numbers other brands use for the same duty. Machine brands at the end of each row are the applications listed by the manufacturer. Tonnage classes for FDNB08 / FDNB12 / FTD26 / FTD45 / FTD48 follow the FRANK catalogue; the 28-52 t rows follow the manufacturer sheet.

Travel drives — published figures

Where the FRANK catalogue publishes a figure, that is the figure we quote; the manufacturer sheet figure is kept only for traceability. Speed and torque are listed per speed range (Speed-1 / Speed-2) because these travel devices shift between two displacements. The last three sizes are not in the FRANK catalogue, so their row carries the manufacturer sheet figures.

Travel drives — brake, pressure and the manufacturer sheet

Brake torque and maximum pressure are not published in the FRANK catalogue; they come from the manufacturer travel device sheet, with the output speed printed there. Where the two sources differ, the FRANK figure in the table above is the one we quote.

Travel drives — flange and outline dimensions

Unit: mm, from the manufacturer sheet — the FRANK catalogue prints the structure drawing but not the dimension table. D1 and D4 are the pitch circles, D2 and D3 the centring diameters, L1 to L4 the axial lengths. P, Pi and Pd are the main, pilot and drain ports; S1 and S2 are the bolt patterns. Measure the flange and the sprocket bolt circle on your machine before ordering.

Travel drive model code

Read the unit code left to right — for example FTD 45 V 45 180/102 35 01. The output torque code and the reduction ratio are the two positions to quote when you ask for a replacement.

Control codes

The letter or digit after the displacement in a model code tells you how the pump is controlled. Power control codes and flow control codes are separate positions in the code, so two units with the same displacement and a different code behave differently in the operator's hands — which is why we confirm it from the nameplate.

Outline dimensions, port positions and control diagrams as the manufacturer publishes them. Use them to check the mounting and the port layout before you order; we confirm the exact variant on your nameplate.

Parts lists

Source and scope. The matrices, control codes, travel drive specifications and parts lists on this page are the manufacturer's published product data (PNM FK Co., Ltd., pnmfk.co.kr), harvested 2026-09-29. Our FLUTEK-range model pages carry the figures from the FLUTEK English catalogue dated 2024-11-25, and the K5V212 / K7V / further M5X / FTD model pages carry these same manufacturer figures - each model page names its own source under the specification table. The travel drive torque, speed, pressure, brake and mounting figures come from the manufacturer's FTD / FDNB travel device specification sheet (unit: mm), checked against the published cross-reference above. The pump power control codes (0 / 1 / 2 / 4 / 5 / 6 / 9 / H) and flow control codes (0 / N / P / M / E / C / D / T) follow the FRANK catalogue pump ordering-code page; the load sensing (L) row comes from the manufacturer sheet, which is also where its diagram comes from. The travel drive tonnage classes follow the FRANK catalogue for the five units it publishes. Part numbers and sizes are facts of the product, not marketing text. Confirm your machine model, shaft and control variant with us before ordering — and treat the manufacturer EPC as the final authority.
