Pump – general 1401
6.2
6.2 Preparations for starting
Note
In the case of a separate pump, it must first be connected to the system in accordance with the
instructions from BBA Pumps. For instructions, contact BBA Pumps.
1. Check the oil levels of the vacuum pump bearings
(1), pump seal (2) and pump bearings (3) (see
chapter ‘Maintenance’).
2. If applicable, the pump is now pre-heated to an
adequate temperature (whether it is necessary to
pre-heat the pump depends on the pumped liquid
and the ambient conditions).
3. When barrier fluid is used, check: whether barrier
fluid is present, has the correct pressure and can
circulate freely. For more information, see the
technical manual for the API Plan 54.
4. Completely open the suction and pressure shut-off
valves.
5. In the case of a bypass line, open the shut-off valve
in the bypass line.
6. If present: check whether the non-return valve is closed.
7. Check whether the direction of rotation of the pump matches that of the motor/engine.
6.3 Starting
The pump must be at a standstill before starting.
WARNING
A backflow of liquid must not be permitted to cause the pump to turn in the opposite
direction when stopped. Such a situation can damage the mechanical shaft seals
that are designed to work in one direction of rotation only.
If this situation can occur, a non-return or shut-off valve must be installed in the
piping to prevent it.
