HP and HPG hand-operated lubrication pumps

For sequential lubrication systems

The HP single-acting, manually operated lever pump is designed for use in sequential lubrication systems to deliver grease through a single outlet. It features a spring-loaded pressure plate and an indicator rod for level monitoring. These pumps can be used with a primary sequential metering device, as well as a secondary metering device.

Like HP pumps, HPG pumps include a dedicated integrated sequential metering unit with eight outlets. This makes the HPG suitable for small, pneumatically driven sequential systems.

Technical characteristics and advantages

  • No power supply required
  • Ease of operation
  • HPG with integrated sequential metering device serves up to 8 lubrication points
  • HPG 15 pumps can be filled via filling nipples
  • Level control using an indicator rod

Application areas

  • Applications without power supply
  • Indoor use
  • Eccentric presses
  • Centrifuges for sludge
