CONTENTS

1. Symbols used in this document

2. General information

These installation and operating instructions are a supplement to

installation and operating instructions for standard CR, CRI, CRN

pumps, publication No 96462123, and for CRN-SF pumps,

publication No 96530119.

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 pressure intensifier (section 9.1)

• by means of a dosing pump (section 9.2)

• 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 25 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.

9. Startup

9.1 Pump with pressure intensifier

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 2607 4601

Operation with positive inlet pressure

• Open the vent screw (pos. A, fig. 1, 2 or 3) 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, 2 or 3) 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 2608 4601

Filling the seal chamber

• Fill the intensifier and the seal chamber with barrier fluid, and

connect the barrier fluid supply pipe to the unused inlet of the

intensifier (pos. 4, fig. 5). The pressure in the seal chamber must

always be 1.5 to 4 bar higher than the pump pressure when the pump

is not operating.

pf= ps* + 1.5 to 4 bar.

pf= To be read on the pressure gauge on the intensifier (pos. 8, fig. 5).

ps= To be read on the pressure gauge in the connection pipe

(pos. 9, fig. 5) between intensifier and pump.

* ps= inlet pressure when the pump is not operating; must always be

0.1 to 5 bar higher than the atmospheric pressure.

TM02 2609 4601

Venting

During filling, the seal chamber and the intensifier must be vented:

• Use the vent screw at the top of the seal chamber (pos. C/D, fig. 1, 2

or 3) and the vent screw at the top of the intensifier (pos. 6, fig. 5).

TM02 2610 4601

Disconnecting the barrier fluid supply pipe

• Disconnect the barrier fluid supply pipe from the intensifier.

TM02 2611 4610

Starting up the pump

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

CRI, CRN pumps.

• 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, 2 or 3).

Connecting the barrier fluid supply pipe

• Connect one end to the seal chamber (pos. E, fig. 1, 2 or 3).

• 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, 2 or 3).

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, 2 or 3) 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, 2 or 3) 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,

CRI, 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 air vent

screw (pos. A, fig. 1, 2 or 3).

10. Maintenance

See the installation and operating instructions for standard CR,

CRI, CRN pumps.

Pressure intensifier

The pressure intensifier is maintenance-free.

Dosing pump

See the installation and operating instructions for the dosing

pump.

11. Operation

To ensure optimum function and performance, check the pressure

regularly.

Pressure intensifier

The pressure difference between the two pressure gauges (seal

chamber and pump) must be between 1 and 1.5 bar.

This indicates that the seal chamber contains sufficient barrier

fluid.

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.

11.1 Frost protection

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

installation and operating instructions for standard CR, CRI, CRN

pumps.

Seal chamber

Drain the seal chamber by slackening the lower plug

(pos. E, fig. 1, 2 or 3).

Pressure intensifier

Replace the barrier fluid by antifreeze liquid.

Dosing pump

For frost protection, see the installation and operating instructions

for the dosing pump.

12. 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.

Subject to alterations.

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.
