suc ion applica ion, remove foo valve
from chemical con ainer.
●Observe relevan safe y pro ocols when
handling par s which have been in con ac
wi h hazardous chemicals.
The following procedures can preven many
po en ial problems:
●The pumper should be inspec ed a
regular in ervals for proper opera ion and
leaks.
●Check he suc ion and discharge valves
for cleanliness, chemical a ack, and scale
build-up.
●A some ime he elas omer par s(O-rings
and diaphragms) will have o be replaced.
Replacemen diaphragms, check valves
and o-rings are available for repairs.
●Periodically shu off he wa er and remove
and inspec he injec ion poin fi ing.
Reac ion of he chemical being injec ed
wi h he chemicals already in he wa er
can some imes cause scale o form. This
can res ric or even comple ely s op
chemical flow. If scale is found, clean i off
horoughly and es ablish a regular
schedule for checking he fi ings.
●Check o be sure all pumpers are properly
primed af er comple ing hese checks and
pu ing he feeder back in o service.

If a feeder will no be used for a long period:
●Remove i from service.
●Flush he pumper and chemical check
valves wi h wa er, or o her sui able
cleansing solu ion, ei her by pumping
wa er hrough he uni (if not feeding
acid) before removing i or by rinsing
hese par s af er removal.
●Tape he valve openings closed while s ill
we . This will pro ec he seals and
preven insec s from plugging up he
openings.
Protect the entire system from
freezing temperatures. Our
warranty does not cover freeze
damage.
Problems With Chemicals
Some chemicals may no be compa ible wi h he
pumper diaphragm. You should check
compa ibili y of a chemical wi h he diaphragm
ma erial before pumping. Because we do no have
con rol of wha chemicals you pump, we do no
warran diaphragms or plas ic heads agains
chemical a ack.
Some chemicals can a ack he diaphragm or
head, causing i o s ick o he head. When his
happens i will no pump.
Changing chemicals wi hou flushing he head can
some imes cause a chemical reac ion which can
damage he diaphragm, plas ic head, or fi ings.
We able powders some imes cake up inside he
head. This reduces he pumping capaci y. If your
uni does no appear o pump as much as i
should, check he calibra ion. You may need o
remove and clean he plas ic head.
Problems With Diaphragms
The mos common problem wi h pumpers o her
han faul y check valves is a rup ured diaphragm.
A rup ured diaphragm will cause drainage ou he
drain hole in he bo om of he cylinder.
It is very important that you
replace a ruptured chemical side
diaphragm immediately. If you
do not, the chemical will attack
other components in the pump
causing them to fail also.
The spring and o her par s in he cylinder can also
be affec ed. Promp a en ion can save added
expensive repairs.
Changing the Chemical Side
Diaphragm
Use precautions when
dangerous chemicals are being
pumped; here you should
remove the chemical check
valves and wash the pump head
to remove any remaining
chemical. Use baking soda to
neutralize acid
●Remove he four screws a aching he
liquid end o pump body.
●Remove he liquid end from he pump
