2.3.2 Pipe connection

If the inlet pipe is longer than 10 m or the suction lift

is greater than 4 m, the diameter of the pipe must be

larger than 1". If a hose is used as inlet pipe, it must

be non-collapsible.

To prevent solids from entering the pump, you can fit

a filter to the inlet pipe. We recommend that you fit a

foot valve on the inlet side.

For suction lifts of over 4 m or for long horizontal

stretches, we recommend that you use an inlet pipe

with a diameter larger than the inlet opening of the

pump.

Fig. 5 Inlet pipe sloping upwards

2.3.3 JPD deep-well installation

A JPD must have the ejector installed in the well.

This means that two pipes are needed for the suction

installation.

Fig. 6 JPD PT installation

The internal diameters of the pipes must

never be smaller than that of the openings

of the pump.

To prevent formation of air pockets, the

inlet pipe must slope slightly upwards

towards the pump. See fig. 5.

2.4 Electrical connection

Carry out the electrical connection according to local

regulations.

Check that the supply voltage and frequency

correspond to the values stated on the nameplate

and that it is possible to make a good earth

connection.

Single-phase motors incorporate a thermal switch

and require no additional motor protection.

Fig. 7 1-phase pumps

DANGER

Electric shock

Death or serious personal injury

- Before starting any work on the product,

make sure that the power supply has

been switched off and that it cannot be

accidentally switched on.

DANGER

Electric shock

Death or serious personal injury

- The protective earth of the socket outlet

must be connected to the protective

earth of the pump. The plug must

therefore have the same PE connection

system as that of the socket outlet. If

not, use a suitable adapter.

We recommend that you fit the permanent

installation with a residual-current circuit

breaker (RCCB) with a tripping current

less than 30 mA.

DANGER

Electric shock

Death or serious personal injury

- If the pump is used for cleaning or

maintenance of swimming pools,

garden ponds or similar places, make

sure that the pump is supplied through a

residual-current circuit breaker, RCCB,

with a rated residual operating current

of 30 mA.

DANGER

Electric shock

Death or serious personal injury

- Power supply cables without a plug

must be connected to a supply

disconnecting device incorporated in

the fixed wiring according to the local

wiring rules.

DANGER

Electric shock

Death or serious personal injury

- The pump must be earthed.

3. Starting up the product

3.1 Priming the pump

1. Remove the priming plug. See fig. 8.

2. Fill the pump with water.

3. Refit the priming plug and tighten by hand.

The pump can now be started.

Fig. 8 Priming the pump

If there is a suction lift, up to five minutes may pass

from the moment the pump is started until it delivers

water. This period depends on the length and

diameter of the inlet pipe.

3.2 Shaft seal run-in

The seal faces are lubricated by the pumped liquid,

meaning that there may be a certain amount of

leakage from the shaft seal.

When the pump is started up for the first time, or

when a new shaft seal has been installed, a certain

run-in period is required before the leakage is

reduced to an acceptable level. The time required for

this depends on the operating conditions, i.e. every

time the operating conditions change, a new run-in

period will be started.

Under normal conditions, the leaking liquid will

evaporate. As a result, no leakage will be detected.

WARNING

Flammable material

Death or serious personal injury

- Do not use the pump for flammable

liquids, such as diesel oil, petrol or

similar liquids.

CAUTION

Impurities in water

Minor or moderate personal injury

- Flush the system with clean water to

remove all impurities before you start

the pump.

CAUTION

Hot surface

Minor or moderate personal injury

- Do not run pump continuously with a

closed inlet or outlet valve.

WARNING

Corrosive substance

Death or serious personal injury

- Do not use the pump for aggressive

liquids.

CAUTION

Hot or cold liquid

Minor or moderate personal injury

- Make sure that the escaping hot or cold

liquid does not cause injury to persons

or damage to the equipment.

CAUTION

Hot surface

Minor or moderate personal injury

- Use protective gloves if the liquid or

ambient temperature is higher than

40 °C.

DANGER

Electric shock

Death or serious personal injury

- Do not use the pump in swimming

pools, garden ponds or similar places if

there are people in the water.

Do not start the pump until it has been

filled with liquid.

The pump must not be started more than

20 times per hour.

The pump must not run without delivering

water for more than five minutes.

TM06 8025 4516

Do not start the pump until it has been

filled with liquid.

4. Product introduction

4.1 JPA JPC

JPA and JPC pumps are horizontal, self-priming

centrifugal pumps.

JPA pumps are made of cast iron, and the JPC

pumps are made of a composite material.

The pumps are designed for pumping water and

other thin, non-aggressive and non-explosive liquids,

not containing solid particles or fibres.

The pumps are especially suited for use in

small-scale agriculture and gardening.

The pumps can be permanently connected to the

water mains or connected to a hose set.

Fig. 9 JPA pumps

Fig. 10 JPC pump

4.2 JPA PM, JPC PM, JPA PT, JPC PT

JPA PM and JPC PM are compact boosters

consisting of a JPA pump and a Grundfos Pressure

Manager (PM 1 version). To reduce the number of

starts and stops, an external tank can be installed.

JPA PT and JPC PT are boosters consisting of a

pump, a pressure switch, a pressure gauge and a

diaphragm tank. The pressure switch automatically

starts the pump according to demand. The

diaphragm tank ensures a constant water pressure

in the water supply.

Fig. 11 JPA PM and PT boosters

Fig. 12 JPC PM and JPC PT

4.3 JPD PT

JPD PT are self-priming centrifugal boosters for

suction lifts up to 27 m. The pump body is made of

cast iron. The high suction lift is achieved by means

of an ejector which can be inserted into wells with a

diameter of down to 10 cm (4"). The boosters are

especially suited for use in small-scale agriculture

and water supply to farmhouses.
