10MCY14-1B 16MCY14-1B Variable Displacement Axial Piston Pump

Model Interpretation: 10MCY14-1B
We can break it down into several parts to understand:
10: Represents the nominal displacement of the pump. The unit is milliliters per revolution (ml/r). So this is a pump with a displacement of 10 milliliters per revolution.
Note: This is the theoretical displacement, and the actual flow rate needs to be multiplied by the rotational speed (considering volumetric efficiency).
M: Representing the import method of the pump.
M represents a quantitative pump.
If it is Y, it represents a variable pump.
(This is a crucial distinction! Your 10MCY is a quantitative pump, while the common 10SCY or 25YCY is a variable pump).
CY: This is the series code.
C usually represents "machine tool" or "series".
Y represents' hydraulic '.
CY together indicates that this is an axial piston pump series that follows the early domestic technology route (especially Shanghai Machine Tool Factory, Qidong High Pressure Oil Pump Factory, etc.), and its structural principle has technical origins with the classic Rexroth A2F inclined shaft pump or domestically improved inclined disc pump.
14: Represents the rated pressure rating of the pump. The unit is MPa.
14 represents a rated pressure of 14 MPa (approximately 140 kgf/cm2).
This is a common pressure rating for early domestic pumps. There will be products with higher pressure levels such as 16MPa, 21MPa, and 31.5MPa in the future.
1B: Represents a design variant code or derived series.
1 is usually the first time to improve the design.
B may represent a certain installation method, shaft extension form (such as a flat key), rotation direction (usually clockwise), or manufacturer's internal code. The specific meaning of B may vary slightly among different manufacturers, please refer to the specific manufacturer's sample.
Summary of Key Characteristics
Type: Diagonal disc axial plug fixed displacement pump.
Core features:
Quantitative output: When the speed is fixed, the output flow rate is basically fixed. It is not possible to adjust the displacement by changing the angle of the inclined plate like a variable displacement pump.
Classic structure: The structure is relatively mature, with many domestic manufacturers and abundant resources for accessories and maintenance.
Medium pressure: The rated pressure of 14MPa belongs to the medium high pressure category and is suitable for hydraulic systems of various equipment such as machine tools, forging, and construction machinery.
