3.1 Transport
DANGER
The pump set could slip out of the suspension arrangement.
Danger to life from falling parts!
▷Always transport the pump set in horizontal position.
▷Never attach the suspension arrangement to the free shaft end or the motor
eyebolt of the pump set.
▷Refer to the weights given in the general arrangement drawing.
▷Observe the local health and safety regulations.
▷Use suitable, permitted lifting tackle, e.g. self-tightening lifting tongs.
To transport the pump set suspend it from the lifting tackle as shown below.
Fig. 1: Transporting the pump set
3.2 Storage and preservation
If commissioning is to take place some time after delivery, we recommend that the
following measures be taken for pump (set) storage.
CAUTION

9 Suction nozzle 10 Shaft seal
The pump is designed with a radial fluid inlet and a radial outlet arranged on the
same axis. The hydraulic system is rigidly connected with the motor.
The fluid enters the pump via the suction nozzle (9) and is accelerated outward in a
cylindrical flow by the rotating impeller (8). The flow profile of the pump casing
converts the kinetic energy of the fluid into pressure energy. The fluid is pumped to
the discharge nozzle (2), where it leaves the pump. The clearance gap (1) prevents
any fluid from flowing back from the casing into the inlet. At the rear side of the
impeller, the shaft (7) enters the casing via the motor flange (3). The shaft passage
through the cover is sealed to the atmosphere with a dynamic shaft seal (10). The
shaft runs in rolling element bearings (5 and 6), which are supported by a motor
housing (4).
The pump is sealed by a standardised mechanical seal.

5 Installation at Site
16 of 36 Trialine / Trialine Z

5.4.1 Connecting the motor
NOTE
In compliance with DIN VDE 0530 - Part 8, three-phase motors are always wired for
clockwise rotation (looking at the motor shaft stub).
The pump's direction of rotation is indicated by an arrow on the pump.
1. Change the motor's direction of rotation to match that of the pump.
2. Observe the manufacturer's product literature supplied with the motor.
5.5 Checking the direction of rotation
CAUTION
Motor and pump running in the wrong direction of rotation
Specified performance data are not achieved!
▷Refer to the arrow indicating the direction of rotation on the pump.
▷Check the direction of rotation. If required, interchange any two phases to
correct the direction of rotation.
The direction of rotation must match that of the arrow indicating the direction of
rotation on the fan hood.
1. Start the pump set and stop it again immediately to determine the motor's
direction of rotation.
2. Check the direction of rotation
The motor's direction of rotation must match the arrow indicating the direction
of rotation on the pump.
3. If the motor runs in the wrong direction of rotation, check the electrical
connection of the motor and the control system, if applicable.

6 Commissioning/Start-up/Shutdown
6.1 Commissioning/start-up
6.1.1 Prerequisites for commissioning/start-up
Before starting up the pump set make sure that the following requirements are met:
▪The pump set has been properly connected to the power supply and is equipped
with all protection devices.
▪The pump has been primed with the fluid to be handled.
▪The direction of rotation has been checked.
▪All auxiliary connections required are connected and operational.
▪After prolonged shutdown of the pump (set), the activities described in (⇨
Section 6.3 Page 21) have been carried out.
6.1.2 Checking the shaft seal
The mechanical seal only leaks slightly or invisibly (as vapour) during operation.
Mechanical seals are maintenance-free.
6.1.3 Priming and venting the pump
CAUTION
Increased wear due to dry running
Damage to the pump set!
▷Never operate the pump set without liquid fill.
▷Never close the shut-off element in the suction line and/or supply line during
pump operation.
1. Vent the pump and suction line and prime both with the fluid to be handled.
2. Fully open the shut-off element in the suction line.
WARNING
Hot fluid escaping under pressure when the vent plug is opened
Risk of electric shock!
Risk of scalding!
▷Protect the electric components against escaping fluid.
▷Wear protective clothing (e.g. gloves).
NOTE
For design-inherent reasons a remaining gas volume in the hydraulic system cannot be
excluded after the pump has been primed for commissioning/start-up. However, once the
motor is started up the pumping effect will immediately fill this volume with the fluid
handled.

leakage, switch off the pump set and re-tighten the bolts between lantern and
casing.
6.1.5 Shutdown
CAUTION
Heat build-up inside the pump
Damage to the shaft seal!
▷Depending on the type of installation, the pump set requires sufficient after-run
time – with the heat source switched off – until the fluid handled has cooled
down.
✓The shut-off element in the suction line is and remains open.
