5.1.1
Vacuum pumps
•
Direct driven, air cooled, oil flooded, rotary vane vacuum pumps are provided as
standard.
•
The pumps are continuously rated and cannot be overloaded by continuous operation at
high vacuum.
•
Each pump includes an inlet filter and a non-return valve is provided at the inlet port to
protect the vacuum vessels and piped distribution system from inadvertent pressurization.
•
A condensate trap is fitted at each exhaust port. Except when mounted directly to the
vacuum vessels each pump is individually mounted on a pump base for maximum
flexibility of the plant layout.
