Pump dimensions.

5. Handling.
The pump must be packaged properly during transport, to avoid damage to the pump or surroundings.
It can be transported and stored in vertical or horizontal position.
Always place the pump on a stable surface, so it cannot tip over during service, transport, testing and
installation.
For storage for long periods of time the pump must be checked again before use. Before electrical
connection, the impeller shall be turned by hand to ensure the parts do not bind.
Accidents in relation to installation can be minimized by taking care.
Be especially careful with the pump’s weight and the risk of electrical accidents.
When lifting with hoisting equipment, these must always be of the correct dimensions with regard
to the lifted weight. Secure pallet and lift the pump using motor eye-bolts.
Never walk under hanging pump.Then lift high enough only to clear pallet, and gently place on a
flat floor surface in a stable upright position.
6. Pump installation.
The pipe system must have at least the same section (DN) as the pump connections.
The pump unit is designed to be installed in the pipeline. Standard piping supports on either side of the
pump should be used, to eliminate pipe and flange stresses.
The suction and discharge pipes must be in line, and the pump must not be used to pull the piping into
place by tightening the flange bolts.
Pipes should be supported near the pump
Never run the pump with suction side and discharge side blocked simultaneously.
Only shunt the pump on the discharge side.
Cavitation in the pump volute may occur, if the pump's suction becomes obstructed.
Cavitation can cause damage to the internal elements of the pump, especially on the impeller.
Always provide the right suction conditions.
Suction.
Connection elements that may cause air pockets, should not be used under any circumstances.
User larger pipes whenever needed, to maintain the water speed in the pipe below 1.2 m/s (4 feet per
second).The suction pipe must be one continuous run from its starting point to the pump.
In order to prevent air pockets and the intake pipe must never be positioned higher than the water level or
the level of the pump.
Whenever, if reducers are required to be used on the pump, then we recommend the use of concentric
reducers.
All pipe systems containing water, must be equipped with valves to prevent flooding during pump
maintenance.
Discharge.
All pipe systems containing water must be equipped with valves to prevent flooding during pump
maintenance.
In order to reduce power and flow losses, we recommend the use of pipes of same (DN) or larger diameter
than the pump discharge.
Elements that may cause air pockets should not be used under any circumstances.
The diameter of the pipes ought to be such, the water speed in the pipe remains below
2 m/s (7 feet per second).

Pump priming.
Never dry-run the pump. Water acts as a coolant for the mechanical seal.
If the pump is operated when dry, the mechanical seal will be damaged, causing leaks, expensive repair and
down-time. Damaged seal by dry-run will not be covered by the warranty.
If the water level is below the level of the pump intake, then use a low resistance check valve / foot valve on
the end of the suction side. The inner DN size in the check valve must not be less than the pump.
Fill the pump and the suction line with liquid from an outside source.
Trapped air should be allowed to escape.
The pump may be stopped with the discharge valve open without causing damage.
However, in order to prevent water hammer effects, as a general recommendation the discharge valve
should be closed first.
7. Electrical installation.
Work is only permitted to be carried out by qualified specialists and must to be
carried out in accordance with local regulations.
Before work commences, ensure that all power is switched off and cannot be
switched on again accidental.
This also applies to the auxiliary power circuits, e.g. anti-condense heaters.
Check that supply voltage and frequency are the same as rated data.
Motors can be used with a supply deviation of ± 5% voltage and ± 2% frequency, according to IEC60034-1.
Connection diagrams for main supply and accessory as PTC or heater are located inside the terminal box.
Connections must be made in such a way, to ensure that a permanently safe electrical connection is
maintained, both for the main supply and the earth connection.
We recommend that crimped connections are made in accordance with IEC 60352-2.
Use always overload switch / motor protection.
The pump must be mounted with a motor guard and a ground fault
circuit breaker.
Tightening torques for terminal board screws:
Thread M5 M6 M8 M10 M12 M16 M20 M24
T.(Nm) 2.5 3.5 7 12 18 35 55 80
Ensure that the terminal box is clean and dry.
Unused cable glands must be closed with blind caps.
Check the terminal box gasket before it is remounted.
Motor space heater: No. 1 - 2
PTC terminals: No. 3 - 4
Bimetal: No. 5 – 6
PT100: No. 7 – 8 – 9
For your motor, please see motor label inside the motor terminal box.
Equipment may vary.

8. Operation.
Before the pump is started for operation, the rotation direction must be checked. At start the
motors starting torque will cause the pump to jerk, and therefore has the pump to be mounted firm
to the base.
Before start, the pump must be fully assembled and ready for operation.
At wrong start rotation, two phases must be switched. See the connection diagram.
Wrong rotation or cavitation in the pump can make loud noise.
NOTE.
If danger of freezing exists, isolate the pump by closing the valve in the pump suction line and discharge and
drain the pump completely.
9. Service & maintenance.
Before any inspection, service or repair of the pump, it has to be physically disconnected from
the power supply. Remove connectors or dismount the wires from the electric board. An
emergency stop can be released accidental or be defective and start the pump by mistake.
All pumps require regular service and preventive maintenance to operate economically and reliably.
The pump should be checked every 6 months and during possible extreme operating conditions more often.
For complete overhaul of the pump contact an authorized pumps workshop or your local DanPumps dealer.
Clean the pump carefully before dismantling it. Follow local and national safety instructions.
Bearings in our DanPumps are lubricated for lift, and don´t need re-lubrication.
Typical duty hours for motor with lifetime lubricated bearings.
Frame size Poles Typical lifetime
56 - 160 2 - 8 40,000h
180 2 - 4 35,000h
200 2 - 4 27,000h
225 2 - 4 23,000h
180 - 225 4 - 8 40,000h
If the mechanical seal need visually inspection or have to be replaced, then never use hydrocarbon liquids
(oil or solvent) to clean mechanical seal parts. Use of oil or solvent will deteriorate material used on the seal.
Use mild soap solution to clean seal parts. Use only your finger to remove dirt. Rinse with clean water and
dry with mild air stream. Use care not to damage or scratch the delicate surfaces.
Check O-rings for cracks or tears.
Note for the electrical motor: Make sure the fan cover is clean which enable the fan wing to cool the motor.

mm. between the back plate and adapter neck.
