  If no grease is coming out of the LUBE Water Pump, here are a few things to check: * Make sure that there is enough grease in the tank or cartridge and replenish if needed, using the same brand and grade. * Ensure you are using the correct, designated cartridge or grease. If not, replace the current grease in the pipes and valves. * Verify that the NLGI# of the grease matches the ambient temperature. * Check the wiring of the power supply and correct it if necessary. * Check the supply power voltage and correct it if it's out of specification. * Bleed any air from the pump. * If your pump has a filter, check if it's clogged and replace it if needed. * There might be problems with the pumping unit or the relief unit (such as foreign particle), so replace them.

Why is the pressure in the main tubing of my LUBE EGM-50TH-10S Water Pump not building up?
- W
  William LiuNov 19, 2025
  If the pressure isn't building up in the main tubing of your LUBE Water Pump, it could be due to several reasons: * There might be no grease discharged from pump due to some causes. Refer to above measures. * There might be air in the tubing, so take off closure plug(s) at the end and operate pump and bleed air in tubing. * Check for grease leaks from the pump discharge port or pipe connection parts on the machine. Tighten them with the proper torque or re-pipe them. * The tubing might be damaged, so replace damaged tubing. * There might be air in the system, so refer to above measures for "Air in the pump" and "Air in the tubing". * Due to a low level of grease in the tank or the cartridge, air is introduced into the pump, so replenish with grease of the same brand and grade ...
