Applications (Where it is used)

.The PSV-PSSO-20CRL is the industry standard for systems requiring smooth energy transmission and operator comfort:

-Machine Tool Hydraulics: The primary choice for Mazak CNC machines, milling centres, and lathes for clamping and lubrication.

-Plastic & Die Casting: Ideal for injection molding where low-pulse pressure ensures consistent part quality.Precision

-Pressing: Provides the smooth, stutter-free movement required for high-accuracy hydraulic presses.

-Automated Production: High reliability for assembly robotics and material handling systems.

Interchangeability & Compatibility. 

The PSV-PSSO-20CRL serves as a direct technical successor to several legacy Racine and Koshin models.

Technical Cross-Reference Table

-Direct Replacement: Functions as a direct swap for various Bosch Racine PSM series and Koshin PSAO equivalent models.

-Mazak OEM Integration: Specifically cross-referenced with Mazak Part #G49ZZ00622V.

-Superseded Codes: Replaces older designations, including PSM-PSAO-07ER-J35F1, T35, and T35E1.

-Installation Note: While functionally interchangeable with the Bosch "B" PSM series, please verify IN/OUT port dimensions as minor piping adjustments may be required.

Note 1:  The item number “B” PSM is used for pumps supplied by BOSCH and is interchangeable with the PSM series. For your reference, we have attached the catalogue for the PSM series and a drawing of one PSM pump model, which has some differences in dimensions of IN/OUT port, etc.
