O-RING
Catalogue part number OORBP1 for FLUTEK K3V / K5V tandem pumps. Drawing position 727.
OORBP1 is the FLUTEK catalogue part number for O-RING in the K3V140 / K3V180 / K5V160 (27-40 t) tandem pump family. It sits at drawing position 727 in the 700 group. It is a service-replacement item, not an assembly, and is picked against the pump serial rather than the machine alone.
O-RING is a K3V140 / K3V180 / K5V160 catalogue line in the DT table, printed on catalogue page 22. On that page it sits next to position 725 (O-RING) and position 728 (O-RING), out of 57 numbered lines in the table. One set takes 6. Every configuration of the family uses this number, DT and DTP included.
