1.2 Description
When fitted to a GV80 pump, the Acoustic Enclosure reduces the noise level emitted from the pump.
Refer to Figure 1. The Acoustic Enclosure has a front panel (12), a rear panel (5), two side panels (3, 11), a top panel
(2), a base assembly (8), a motor partition (1) and an inlet partition (4). The panels are secured in place by four
manually operated catches (13).
The right-hand side panel (3) has a leadthrough hole to allow you to connect the pump-outlet to your exhaust-
extraction system. The left-hand side panel (11) has a transparent sight-glass, which allows you to see the oil-level
in the pump. The top panel (2) has a leadthrough hole which allows you to connect the pump-inlet to your process
system.
The base assembly (8) has: a cable-gland (7) for the pump electrical supply cable; a services panel (10) with
connectors which allow you to connect your cooling-water supply and return pipelines and your nitrogen supply
pipeline to the pump; castors (6) which allow you to move the pump, and levelling feet (9), which allow you raise
the pump off of the floor so that it is level and does not rest on the castors.
With the exception of the base assembly, all of the panels are made from mild steel and have acoustic foam on the
interior surface(s).
Warnings are given where failure to observe the instruction could result in injury or death to
people.
