Product & Chemical Disclaimer

The user must take responsibility in the selection of the products materials of construction. Empire

Pumps Ltd will act in an advisory role and offer recommendations; however, the user is liable for the

product selection in line with solutions and temperatures in which the equipment is operated.

Safety Precautions

WARNING: Prior to operating the filtration system read and understand the operating and maintenance

instructions.

WARNING: Ensure the filtration system is compatible with the fluids and temperatures being

transferred. Always consult Empire Pumps Ltd if there is any change in chemical concentrations or

solution temperatures.

WARNING: Wear protective eye and personal equipment at all times when operating the pump. Follow

standard safety procedures when handling corrosive or harmful solutions.

WARNING: Ensure all operators of this equipment have been trained for safe working practices,

understand its limitations and wear safety goggles and equipment at all times.

WARNING: Correct procedures must be followed to drain the pump of all chemistries prior to physical

inspection of the pump.

WARNING: Excessive Pressure. Can result in serious injury or equipment damage. Do not service or

clean the pump whilst the system is pressurised. Relieve pressure from the system prior to

disassembly.

WARNING: Never operate the filtration system above the specified maximum operating pressure of the

pump.

WARNING: Suction and discharge connections must be compatible with the solutions being pumped

and the maximum pressure capability of the filtration system.

WARNING: Maximum temperatures are based on mechanical stress only. Certain chemicals will

significantly reduce the maximum operating temperature of the pump materials. Consult with the

chemical manufacturer and Empire Pumps Ltd for solution compatibility and temperature limitations.

WARNING: The filtration system must not be used as structural support to the piping system. Ensure

suction and discharge pipe-work are independently supported to avoid stress on the pump parts.

WARNING: Use only Empire Pumps Ltd genuine spare parts to assure compatible pressure rating and

longest service life.

WARNING: Re-torque all fasteners before operation. Excessive torque is unnecessary and may cause

damage to the pump.

WARNING: Upon receipt of the filtration system, inspect for any signs of shipping damage. If damage

has occurred contact Empire Pumps Ltd.

a

perforated

bag

support

basket.

There

is

an

inner

gasket

fitted

under

the

basket.

Check

the

'O'

ring

groove

and

inner

gasket

for

any

damage,

and

place

inner

gasket

in

the

These

should

be

loosened

before

fitting

Putting the filter into service

Ensure

the

inlet

and

outlet

valves

are

shut.

Ensure

that

the

drain

valve

(if

fitted)

is

closed

or

the

drain

plug

is

fitted.

Open the

vent

valve

or

plug.

Gradually

open

the

inlet

valve

on

the

upstream

side

of

the

filter

housing

whilst

ensuring

that

the

down

stream

valve

remains

closed.

As

the

housing

fills,

air

will

be

expelled

from

the

vent.

When

all

the

air

has

been

expelled,

fluid

will

begin

to

flow

from

the vent.

For

safety

reasons,

it

is

important

to

ensure

that

vent

and

drain

connections

are

secure

and

that

released

fluid

is

disposed

of

to

an

appropriate

drain

or

container.

Appropriate

measures

should

be

taken

if

the

liquid

is

hazardous.

Close the

vent

valve

or

plug,

then

slowly

open

the

outlet

valve

–

the filter is

now in service and no attempt should be made to open the closure.

Regular

venting

of

the

housing,

by

opening

the

vent

to

permit

any

trapped

air

to

be

expelled,

will

maintain

the

operating efficiency

of

the

filter.

For

safety

reasons,

it

is

important

to

ensure

that

venting

is

ONLY

performed

via

a

valve,

that

the valve

is

opened

with

extreme

care

and

that

released

fluid

is

disposed

of

to

an

appropriate

drain

or

container.

Appropriate measures

should

be

taken

if

the

liquid

is

hazardous.

The

filter

can

be

operated

until

the

increase

in

the

pressure

differential

across

the

filter

bag

reaches

approximately

1.5

bar g

(25psi)

and

at

this

point

the

filter

bags

should

be

replaced.

Removing the filter from service

Close

the

outlet

valve

Close

the

inlet

valve

Caution

-

the

filter

housing

will

still

be

under

pressure

at

this

point.

Before

opening

the

filter

housing,

the

pressure

must

be

relieved.

This

can

be

done

either

by

carefully

opening

the

vent valve

or

plug

or

the

drain

valve

or

plug,

whichever

is

most

appropriate.

Before

opening

the

closure,

open

the

drain

valve

or

plug

to

allow

all

of

the

fluid

to

drain

out

of

the

housing.

The

vent

must be

open

to

allow

the

housing

to

drain

properly.

If

the

fluid

is

hazardous,

appropriate

measures

should

be

taken

before

opening

the

closure.

For

safety

reasons,

it

is

important

to

ensure

that

vent

and

drain

connections

(such

as

any

valves

or

hoses)

are

secure

and that

released

fluid

is

disposed

of

to

an

appropriate

drain

or

container.

Replacing the filer bags

Open

the

filter

housing

according

to

the

instructions

given

in

the

section

“Opening

the

Filter

Housing”

.

Remove

the

sprung

bag

compression

plate

by

pushing

down

on

the

‘T’

bar

and

turning

anticlockwise

to

clear

the

retaining lugs.

Remove

the

filter

bags

from

the

basket

and

dispose

of

as

detailed

in

the

section

“Spent

Filter

Bag

Disposal”

.

In

some

processes,

such

as

tank

recirculation

systems,

it

may

be

acceptable

to

simply

fit

a

new

bag

without

a

cleaning procedure,

as

described

under

“Fitting

the

Filter

Bags”

.

However

in

straight

through

systems

it

may

be

considered necessary

to

completely

clean

the

filter

vessel

before

fitting

a

new

bag.

In

that

case

lift

the

basket

from

the

housing

being

careful

to

lift

the

‘O’

rings

also,

so

that

they

do

not

accidentally

drop

inside

the

vessel,

clean

the

basket,

‘O’

ring

and

vessel

by

hand

or

by

flushing

–

whichever

is

appropriate

for

the

application

and

reassemble

as

described

in

“Fitting

the Perforated

Basket

”,

“Fitting

the

Filter

Bags”

,

“Closing

the

Filter

Housing”

and

“Putting

the

Filter

into

Service”

.

Spent Filter Bag Disposal

The

spent

filter

bags

should

be

disposed

of

in

a

responsible

manner.

The

filter

itself

can

be

disposed

of

by

incineration

or as

landfill

by

an

authorised

contractor;

however,

it

is

important

for

the

user

to

check

how

the

contaminant

contained

in

the filter

should

be

disposed

of.

Maintenance

The

filter

housing

will

require

very

little

maintenance.

The

outer

surface

should

be

kept

clean

and

free

from

dirt.

This

will

prevent

contamination

of

the

filter

during

bag

change. The

Vee

clamp

should

be

maintained

as

follows:

A

small

amount

of

a

suitable

lubricant

should

be

used

on

the

sliding

surfaces

of

the

clamp.

The

clamp

adjuster

thread

must

be

periodically

greased.

We

recommend

the

use

of

molybdenum

based

grease

which

will

adhere

to

the

thread.

Binding

of the

threads

could

occur

if

they

are

not

lubricated

regularly.

internally

and

externally

on

a
