Dual line centralized lubricating systems are divided into the following four major types according to drive method and piping system:
(1) Manually operated end type system
(2) Motor driven lance type system
(3) Motor driven end type system
(4) Motor driven loop type system
The following table summarizes the component equipment of each system and their combinations. (For details, refer to the Equipment Manual.)

(Notes)
• For details on oil use of a dual line centralized lubricating system, consult us separately.
• The number of lubricating ports and allowable piping (for loop type: length of loop section, for end and lance types: length from pump to terminal) in the above table are shown as the equivalence of the NLGI consistency #1 grease and DV-30 type distributing valve.
• Replenish the pumps and tank with grease by using a grease filling pump via the replenishing port.
• Standard voltage of electric motor
AC200V 50/60HZ AC220V 60HZ
AC400V 50/60HZ AC440V 60HZ
• Consult us regarding different voltages.
