PIPE SUPPORT:
All piping, should be supported indcpendenfly neor the pump.
Pipes must register with the Pump connecions without
being stroined into position.

chonges in pipe diometers. The suction line must be os
shori ond direct os possible. Avoid shorp turns, use bends
rother fhon elbows. When loying the line, o uniform grode
should be mointoined, rising towords the Pump the whole
woy.
When instolling for outomotic operotion by Floot Switch cnd
fhe woter level is below the Pump, obtoin on instollotion
sketch from us, os speciol fittings ore required
FOOTVALVE:
Where the woter level is below the Pump, o Footvolve or
Check Volve should be used. The lotter is only used with
Speor Points. The Volve should hove on oreo ot leost one
ond o holf times thof of ihe suction pipe. The sfroiner
should hove o cleor oreo three io four times thot of ihe suction
pipe.

STARTING:

For the initiol sfort it is necessory to prime the Pump. This
con be done by removing the plug on the Pump body iusf over
fhe top of the suction pipe connection ond filling the whole
of the suction pipe with woter lt sometimes becomes necessory
to ol so remove the top cover of the Pump ond fi ll wiih woter.
This is removed by undoing the one bolt on the top.
VALVES:
Volves moy be inspected by removing fhe volve covers for
the suction volves ond the oir chomber for the delivery volves.
The volves con be removed from the Pump by unscrewing the
volve sfem with o screwdriver. Volves should not be disturbod
unless trouble is suspected, ond if the rubbers ore disturbed
they should be removed from the Pump ond rubbed ogoinst o
piece of emery poper supported on o flot surfoce until they
ore perfectly flot. lf excessively pitted, the rubbers moy be
reversed ond the other side used; or reploced i{ necessory.
DELIVERY PIPE:
The size of the delivery pipe should be selected so fhot the
friction heod is not excessive. lf delivery pipe is too smoll
frictionol heod is very greotly increosed, consequently more
power is reguired to drive the Pump. 'Avoid
shorp furns'
use bends rother ihon elbows. lt is odvisoble for del ivery
piping to ri se ol lthe woy to the point of dischorge'
Unions or flonges should be used fo connect the piping to
the pump, so thot the pipes con be disconnected, if necessory,
without disturbing the whole instollotion'
A relief Volve must be fitted to delivery line neor Pump if
ony Gote Volves or Tops ore in it to guord ogoinst domoge
to the pumps or motor in the event of the outlet being closed
whilst the pump is oPeroting.
PLUNGER LEATHERS:
Will possibly need replocing obout every eighieen months or
so. By removing the Cylinder Heod (held down by rwo bolts)
the Plunger con then be unscrewed by meons of the slot in
the centre of the Plunger Assembly. When removed from the
Pump, the Plunger con hen be token oporf ond new leofhers
fitted.
Moke sure thot fhey ore well oiled ond soft ond thot the
Cylinder Liner is not excessively scored. Turn the Pump
by hond to bring the Plunger well forword in the Cylinder.
lf the Pump hos been stonding for some time the Plunger
Leothers moy become hord ond dry. This will greotly impoir
.,re oporotion of the Pump. The leothers should be removed
from the Pump ond sooked in coslrqr or neoisfoot oil,
or, if this not ovoiloble, woter, for some hours. They
should then be worked with the fingers until soft, ond repfoced
in the Pump.

This should be iust right enough to permit o slow drip from
the glond when the Pump is operoting. lf the glond is too
rightl the Pump will use excgssive power ond fie plunger
rod will weor roPidlY.
When oll the odiustment hos been token up, the Glond Nut
should be unscrewed ond withdrown, thence the smoll ferrule'
The old pocking should be scroped out with o noil or piece
of wire qnd new pocking (6" - 9" ol 3/16" grophited Volve
f*ist) wropped oround ih" Plung"t Rod ond pressed into the
Glond.
Aftcr the Glond Nut hos been tightened il compressgs the
po"ting ond usuolly I or 2 more turns of pocking con then be
fitted.

LUBRICATION:
Provided thot the sump is kept filled with oil, lubricotion is
guite outomotic. Oil level in the sump when the Pump is
sfotionory should never foll below the bottom of the filler
plug hole.
The Filling Plug con be found on the bock of the Cronkcose,
while o dioin plug is underneoth for periodicol replocement
of the oil.
sufficienr sAE 20-40 Engine oil should be odded to fill the
cronkcose to fhe fi ller plug level. core should be tokcn thqt
the sump is reolly full, os sometimes o smol I bubble qcrossthe
Ltto, of the fil'ler hole gives the impression thqt it is full
when such is not the cose. About every six months the sump
should be droined ond refilled with new oil.
