Description
The ISHAN YESA and YESB series represent high-efficiency automatic electric piston pumps engineered for centralized oil lubrication systems. Designed to deliver precise, volumetric fluid displacement, these lubricators ensure continuous film maintenance on critical sliding surfaces, guideways, and ball screws. The integration of a robust piston mechanism guarantees stable pressure output, mitigating the risk of dry friction and mechanical wear in high-cycle industrial machinery.

Original Engineering and Technical Compatibility
Manufactured under strict Original Engineering standards, the YESA and YESB units feature a highly durable cam-driven piston architecture. The YESA series typically incorporates an integrated electronic timer for autonomous cycle control, whereas the YESB series is optimized for direct PLC integration, allowing host machines to dictate lubrication intervals. Both models ensure seamless Technical Compatibility with standard volumetric distributors, proportional junction blocks, and hydraulic lubricant oil networks.
Industrial Application
These automatic lubricators are critical for maintaining the operational integrity of CNC machining centers, automated lathes, injection molding machines, and high-speed stamping presses. By delivering exact micro-doses of hydraulic lubricant oil to linear guideways and thrust bearings, the system prevents thermal expansion and mechanical degradation during continuous, multi-shift manufacturing cycles. The automated delivery eliminates human error in preventative maintenance protocols.
Procurement and Lead Time
Our logistics framework ensures an optimized Lead Time for both standard component replacements and new system integrations. Each lubrication unit undergoes rigorous pressure retention and flow verification testing prior to dispatch, ensuring immediate deployment capability and long-term reliability in harsh industrial environments.
