CM-20 Pipe Cutting Machine – Hydraulic System Update

Summary

This article documents the current hydraulic system configuration of the CM-20 pipe cutting machine. Based on a new set of on-site photos, it shows the transition from an integrated hydraulic design to a split structure with separate pump and cylinder. The update reflects structural considerations and real working conditions across the product line.

CM-20 Pipe Cutting Machine – Hydraulic System Update
A new set of on-site photos has recently been taken for the CM-20 pipe cutting machine.
These images reflect an actual update to the hydraulic system structure of the CM-20 and document the machine in its current configuration.

Compared with earlier versions, the current CM-20 uses a split hydraulic system instead of the former integrated design.
In this updated layout, the hydraulic pump and the cylinder are arranged as separate components rather than being combined into a single assembly.
Basic Positioning of the CM-20
The CM-20 is an electric hydraulic pipe cutting machine designed for cold cutting of steel pipes in the 8"–20" range.
It is suitable for both workshop fabrication and on-site use, with the overall design focused on cutting stability and adaptability to different working environments.
Changes in Hydraulic System Structure
In previous versions, the CM-20 adopted an integrated hydraulic structure, where the pump and cylinder were housed together as one unit.
In the current version, this arrangement has been replaced by a split hydraulic structure.

With the updated design, the hydraulic pump and the cylinder are installed separately and connected through hydraulic hoses.
From the machine layout shown in the on-site photos, the functional roles of each component are more clearly defined: the pump operates as an independent unit, while the cylinder is dedicated to executing the cutting action.
Unified Pump Configuration
The hydraulic pump used on the current CM-20 is the same model as that used on the RG-2X.
Adopting this pump as a standalone module allows a consistent hydraulic solution to be maintained across different machine models and also simplifies maintenance and configuration management.
Application of Sealed Split Pumps Across the Product Line
The use of sealed split hydraulic pumps is not limited to the CM-20.
At present, the 8-inch, 12-inch, and 20-inch pipe cutting machines in our product line all adopt the same type of split, sealed hydraulic pump.

Compared with integrated pumps that feature ventilation holes, the sealed split structure provides a more straightforward layout, with the pump fully enclosed.
This design helps reduce the influence of external environmental factors on the hydraulic system and supports more stable operation during continuous work or on-site applications.
About the New Photo Set
The newly updated photos were taken based on the current split hydraulic configuration.
They show the actual arrangement of the hydraulic pump, cylinder, and hoses, reflecting the real structure of the current CM-20 version rather than a conceptual or illustrative layout.
Conclusion
This hydraulic system update was made based on structural considerations and real-world usage conditions.
The CM-20 has now been documented in its current configuration through a new set of on-site photos, which accurately represent the machine’s present structure.
