Notes:
1) All the above pump casings can be supplied for clockwise or
counter clockwise rotation. The casings are interchangeable
with each other although pump suction and discharge
positions change – refer to the relevant Sectional
arrangement drawing. The LLR has 1
st and 2 nd stage
impellers, which are not interchangeable with each other.
2) The same shaft is used for gland packing and component
mechanical seals. Cartridge mechanical seals use a
different series of shafts fitted with impeller nuts – see
relevant Sectional arrangement drawings.
3) Gland packing and inch-type component mechanical seals
use the same shaft sleeve. Includes shaft sleeve, shaft nut,
gland, packing, lantern ring, stuffing box bush and
mechanical seal. When metric seals are fitted a different
diameter shaft sleeve and nut is used.
4) Includes bearing housing, bearing cover, ball bearing set,
bearing nut and washer (except 2.5LR-10 which uses the
bearing nut and washer from the 1.5LLR7 group).
5) Dimensionally the same as other J, but may have had a
material upgrade to handle some of the higher power
applications.
