Multiquip EM16747 Water Separator Assembly - OEM Replacement Part

The water separator assembly removes moisture and contaminants from the hydraulic system, protecting critical components like the main axial piston pump from damage caused by water infiltration. This assembly is essential for maintaining proper hydraulic oil quality in concrete pump operations, where hydraulic systems operate under high pressure—up to 1750 psi accumulator pressure during normal operation.

In Multiquip concrete pumps, the hydraulic system transfers oil through slave circuits between cylinders during pumping cycles, making clean, dry hydraulic fluid critical for reliable performance. Water contamination can cause severe damage to the main axial piston pump and compromise the precision hydraulic transfers that control piston stroke timing. Regular inspection of this separator assembly is part of proper hydraulic maintenance, particularly when operating in environments below 50°F or when using the recommended Shell Oil Tellus 68 or Mobil DFE 26 hydraulic oils in the 50-gallon reservoir system.

• LS-40, LS-40TD, LS-50TD
