The SILCA NFS Pump Blood is a 100% pure synthetic oil that has been optimized for adhesion to SILCA leather gaskets and to coat pump tube walls. The result: lower pumping force, higher pumping efficiency and longer leather seal wear due to reduced friction and heat. Due to the red coloring, this lubricant is nicknamed "Pump Blood".
SILCA recommends adding a few drops of "Pump Blood" to your pump every 6 months to every year. By coating the walls, the pump is kept at maximum efficiency with minimal effort.
