• Install the seal washers (8.08) and the seal screws (8.09)

• Install the L-cup (8.01) and the rotary face (8.02) into the

rotor (2.01)

5.4 dOUblE sEal - sla,

slb, slC

• Install the O-ring (8.06), lip-seal (8.17) and the cir-clip (8.18)

into the seal housing and then install the seal housing (8.16)

into the casing

NOTE:

On the SLG only the lipseal runs directly on the pump

shaft and not a sleeve
• Install the O-ring (8.04) onto the static seal (8.03) and then

install the static seal into the casing – ensure that the location

slots line up with the pins in the seal housing

The seals are now assembled.
For rotor and head installation see pump assembly section.

The washers overlap the seal bore – This locates and provides

drive to the seal.
