6.1 Commissioning/start-up
6.1.1 Prerequisites for commissioning/start-up
Before commissioning/starting up the pump set, make sure that the following
conditions are met:
▪
The pump set has been properly connected to the electric power supply and is
equipped with all protection devices.
▪
The pump has been primed with the fluid to be handled. The pump has been
vented.
▪
The direction of rotation has been checked.
▪
All auxiliary connections required are connected and operational.
▪
The lubricants have been checked.
▪
After prolonged shutdown of the pump (set), the activities required for returning
the pump (set) to service have been carried out. (

Section 6.4 Page 28)
▪
The lock washers, if any, have been removed from the shaft groove.
▪
The shaft can be easily rotated by hand.
6.1.2 Priming and venting the pump
DANGER
Risk of potentially explosive atmosphere inside the pump
Explosion hazard!
▷
Before starting up the pump, vent the suction line and the pump and prime
them with the fluid to be handled.
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.
An Rp 3/8 " ball valve (743) is provided for complete venting of the mechanical
seal chamber. The mechanical seal chamber must be vented prior to
commissioning as well as every time the suction strainer has been cleaned.
2. Fully open the shut-off element in the suction line.
3. Fully open all auxiliary feed lines (barrier fluid, flushing liquid, etc.), if any.
NOTE
For design-inherent reasons some unfilled 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.
