Expansion Tanks for Lubricants
A rolling rubber diaphragm maintains tank pressure at or near 0 psi, which extends seal life to help keep lubricants clean. Use these tanks to accommodate the expansion of heated lubricants and provide a cushion of compressed air in closed lubricant-heating systems. They prevent lubricant loss by eliminating the need to expel hot lubricant from systems during each heating cycle.
