2. General information

These installation and operating instructions are a supplement to

installation and operating instructions for standard CR, CRN

pumps, publication No 99078486.

3. Product description

This type of double seal consists of two shaft seals mounted in a

"back-to-back" arrangement in a separate seal chamber.

The pressure in the seal chamber is higher than the pump

pressure.

The double seal arrangement with pressurised seal chamber

prevents the pumped liquid from leaking to the environment via

the shaft seal.

The pressure in the seal chamber can be generated in three

ways:

• by means of a dosing pump (section 8.1)

• by means of an already existing system.

4. Applications

The shaft seal is available for the following Grundfos pumps:

This type of shaft seal is the optimum solution when handling

abrasive or sticky liquids which would either wear out, damage or

block a mechanical shaft seal.

Recommended for applications involving toxic, aggressive or

flammable liquids, the seal shaft protects the surrounding

environment and the people working in the vicinity of the pump.

5. Maximum liquid pressure and temperature

Due to the shaft seal design, the pressure in the seal chamber

must not exceed 30 bar. The pressure of the barrier fluid must

always be higher than the pressure of the pumped liquid.

The maximum temperature of the barrier fluid depends on the

rubber material of the shaft seal.

8. Startup

8.1 Pump with dosing pump

Warning

Pay attention to the orientation of the vent holes,

and take care to ensure that the escaping liquid

does not cause personal injury or damage to the

motor or other components.

When handling hot or hazardous liquids, special

attention should be paid to the risk of personal

injury.

When pumping flammable liquids, beware of static

discharges. The funnel, for instance, should be

earthed!

Illustration Step Action

TM02 2612 4601

Connecting the barrier fluid supply pipe

• Connect one end to the seal chamber (pos. E, fig. 1).

• Connect the other end to the outlet of the dosing pump.

TM02 2613 4601

Recommended pressure

• Set the start pressure of the dosing pump to a pressure 1.5 to 2 bar

above the highest pressure the pump can deliver.

(Ppump + Pinlet + P1.5 - 2.0 < Pdosing max.)

TM02 2614 4601

Filling and venting the seal chamber

• Start the dosing pump.

• Fill and vent the seal chamber by means of the vent screw at the top

of the seal chamber (pos. C/D, fig. 1).

The dosing pump will stop automatically when the pressure set in

step 2 has been reached.

TM02 2615 4601

Operation with positive inlet pressure

• Open the vent screw (pos. A, fig. 1) on the side of the pump head.

• Close the isolating valve on the discharge side.

• Open the isolating valve on the inlet side.

• Slowly fill the pump with the liquid to be pumped.

When the liquid starts running out of the vent hole, immediately close

the vent screw.

Operation with suction lift

• Open the vent screw (pos. A, fig. 1) on the side of the pump head.

• Close the isolating valve on the discharge side.

• Fill the pump and the inlet pipe with the liquid to be pumped using a

funnel.

• When the liquid starts running out of the vent hole, immediately close

the vent screw.

Note: A non-return valve must be fitted to the inlet pipe.

TM02 2616 4601

Starting up the pump

• See also the installation and operating instructions for standard CR,

CRN pumps.

• Open the isolating valve on the discharge side.

• Start the pump, and check the direction of rotation.

See the correct direction of rotation on the motor fan cover.

• After a few minutes, vent the pump again by means of the vent screw

(pos. A, fig. 1).

1,5 - 2 bar

English (GB)

9. Maintenance

See the installation and operating instructions for standard CR,

CRN pumps.

Dosing pump

See the installation and operating instructions for the dosing

pump.

10. Operation

To ensure optimum function and performance, check the pressure

regularly.

Dosing pump

The pressure of the barrier fluid must always be 1.5 to 2 bar

higher than the pressure of the pumped liquid. This is

automatically checked by the pressure switch/ transmitter fitted

together with the dosing pump.

10.1 Frost protection

For general guidelines on frost protection of the pump, see the

installation and operating instructions for standard CR, CRN

pumps.

Seal chamber

Drain the seal chamber by slackening the lower plug (pos. E, fig.

1).

Dosing pump

For frost protection, see the installation and operating instructions

for the dosing pump.

11. Disposal

This product or parts of it must be disposed of in an

environmentally sound way:

1. Use the public or private waste collection service.

2. If this is not possible, contact the nearest Grundfos company

or service workshop.

Note

A very small quantity of the barrier fluid, i.e. less than

10 ml/24 operating hours, will always flow into the

pumped liquid.

Warning

If the pumped liquid is hazardous to health, take

special care when draining the pump. Local safety

regulations must be observed.

2. Обща информация

Настоящите инструкции за монтаж иексплоатация са

допълнение към инструкциите за монтаж иексплоатация

за стандартни помпи тип CR, CRN, публикация No 99078486.

3. Описание на продукта

Този тип двойно уплътнение се състои от две уплътнения на

вала, разположени в"back-to-back" позиция вотделна

уплътнителна камера. Налягането вуплътнителната камера е

по-голямо от налягането на помпата.

Наличието на двойно уплътнение схерметизирана

уплътнителна камера не позволява изтичане на работна

течност към околната среда през уплътнението на вала.

Нялагането вуплътнителната камера може да се генерира по

три начина:

•спомощта на дозираща помпа (раздел 8.1)

•спомощта на вече налична система.

4. Приложения

Уплътнението на вала еналично за следните помпни на

Grundfos:

Използването на този вид уплътнение енай-доброто решение

при работа сабразивни или лепкави течности, които водят до

износване, повреда или блокиране на едно механично

уплътнение на вала.

Препоръчано за приложения, включващи токсични, агресивни

или възпламеними течности, уплътнението на вала

предпазва средата илицата, работещи вблизост до помпата.

5. Максимално налягане итемпература на

течността

Поради дизайна на уплътнението на вала, налягането в

уплътнителната камера не трябва да надвишава 30 бара.

Налягането на бариерния флуид трябва винаги да епо-

високо от това на работната течност.

Максималната температура на бариерния флуид зависи от

гумения материал на уплътнението на вала.
