Tokio Keiki P21V-RS-11-CMC-10-J Piston Pump
The P21V-RS-11-CMC-10-J is a high-performance variable displacement axial piston pump from Tokio Keiki, uniquely equipped with a solenoid-controlled two-pressure compensator. This pump is designed for sophisticated hydraulic systems that require the ability to switch between two different pressure settings electronically. By integrating a solenoid valve directly onto the pump’s compensator, the P21V series allows for seamless transition between high and low pressure, optimizing energy consumption and machine performance in applications like clamping, pressing, and automated machining.

Key Features for Industrial Applications
Dual-Pressure Solenoid Control (CMC)
The «CMC» control feature allows the operator to switch the pump’s pressure compensation setting via an electrical signal. This is ideal for machines that require a «High-Low» cycle—such as a fast approach at low pressure followed by a high-pressure work stroke. This electronic switching reduces the complexity of external valving and allows for faster cycle times.
Energy Efficient «Silent» Technology
Part of the P-series lineage, the P21V-RS-11-CMC-10-J is engineered for quiet operation. Even during pressure compensation phases, the pump maintains low acoustic levels through optimized internal fluid dynamics and a high-rigidity housing. This makes it suitable for modern factory environments where noise reduction is a priority.
