Electrically operated piston pump with lightning protection
The Lincoln P623S and P623M electrically operated pumps have been designed to withstand electromagnetic pulses caused by lightning strikes. An extension of the P603 pump series, the P623S is for use in single-line automatic lubrication systems, while the P623M is for use in progressive automatic lubrication systems.
Working closely with customers to develop product solutions that meet specific needs, SKF developed the P623S and P623M for onshore and offshore wind energy applications. In addition, these pump units are suitable for use in construction, mining and renewable energy applications where lightning protection must be considered.
The P623S and P623M pumps feature a power supply board that transfers 230 V to 24 V (control) with overvoltage protection to discharge 8 KV (electric grounding).
The pump units are available with a grease follower plate for rotating applications or a stirring paddle for stationary applications.
Features and benefits:
- Reduces operational risk compared to standard automatic lubrication
- Offers higher safety standards
- Brings lubrication system into compliance
- Protection class IP 67
