RH pump stations can be used in single line resistance lubrication system (SLR), progressive lubrication system (PRG) and positive displacement injector lubrication system (PDI). A pressure switch be used to control the system work frequency when used in PDI lubrication system. If equipped with magnetic filter, they can also be used in cyclic system to ensure lubrication of large mechanical equipment such as machine tools and injection molding machines. Various hydraulic systems and pump stations can be designed and manufactured to special needs of user.
