P623S Electric Drive Pump

For single-line lubrication systems

The P623 S electric-driven pumps were designed to withstand electromagnetic pulses (EMPs) from lightning strikes. The P623 S is an updated version of the P603 series pumps and is intended for single-line automatic lubrication systems.

Working closely with customers to develop products tailored to their specific needs, SKF developed the P623 S pump for marine and offshore wind applications. These pumps are also suitable for applications in construction, mining, and renewable energy where lightning protection is required. P623 S pumps are equipped with power supplies that convert 230 V to 24 V (control) with overvoltage protection, allowing for discharge of 8 kV (electrical ground). Pumps are available with a clamping plate for use in rotating applications or with a stirrer for stationary applications.

Technical characteristics and advantages

  • Reduced operational risks compared to standard automatic lubrication systems
  • High safety standards
  • Compliance of the lubrication system with high requirements

Application areas

  • Wind energy systems
  • Construction and mining equipment
  • Renewable energy sources
