Assembling the LMV-803Lr

Diffuser Assembly

1.01 Place o-ring and face seal in their

respective face grooves on the diffusers.
Carefully lower the diffuser into the pump
case.

On cryogenic applications, no seal is used on
the diffuser eye diameter.

NOTE: On cryogenic applications, no

seal exists on the diffuser eye

.

NOTE: In cryogenic applications, the

grooves for the seals are highly
polished and care must be taken
to avoid any scratches or nicks

.

1.02 Align the witness marks on the pump case

and diffuser. Press diffuser into place so
the top is flush with the top of the pump
case (within .062”).
