DESIGN

• These are end suction, single stage centrifugal pumps. These
three pumps, YNM 525, YNM 825 and YNM 1531 are used for
flow rates ranging between 50 and 1250 gpm.
• The main pump dimensions are compatible with DiN 24256.
The pump flanges are designed according to UL standards
ANSI/ASME B16 Class 250.
• The pump performances are compatible with UL standards.
• The single suction, closed type impeller is dynamically
balanced against the thrust by use of back wear rings.
• Shaft leak prevention is provided by 5 unit soft packing
according to UL448 requirements.
• The parts inside the pumps that are in contact with water,
such as bolts or bolt screws, are made of non-corrosive materials
