Unpack And Inspect; Locate The Pump; Fill The Pump With Oil - Edwards RV3 Instruction Manual

A652–01–880 Issue Y
Provide for a purge of inert gas when shutting down the pumping system, to dilute dangerous gases to safe

concentrations. A suitable gas ballast adaptor for introduction of purge gas into the pump is available as an
accessory (see Section
requirements if required.
3.3

Unpack and inspect

The mass of the RV8 and RV12 pumps is approximately 29 kg.
For the RV8 and RV12 pumps attach the mechanical lifting equipment to the lifting bracket on the
pump. Slings do not need to be used to move the RV8 and RV12 pumps.
1. Remove all packing materials, and remove the pump from its packing-box.
2. Remove the protective covers from the inlet and outlet-ports and inspect the pump. If the pump is damaged,
notify the supplier and the carrier in writing within three days; state the Item Number of the pump together
with the order number and the supplier's invoice number. Retain all the packing materials for inspection. Do not
use the pump if it is damaged.
If the pump is not to be used immediately, replace the protective covers. Store the pump in the conditions, described
in Section 6.1. Refer to Section 6.2
3.4

Locate the pump

The RV3 and RV5 pumps have a lifting handle enabling the pump to be moved by hand. If using mechanical lifting
equipment, do not attach the equipment to the handle; for stability, use slings around the motor and the pump-body.
Provide a firm, level platform for the pump. Locate the pump so that the oil-level sight-glass is visible and the oil
filler-plug, oil drain-plug, mode selector and gas-ballast control are accessible.
If the pump will be located inside an enclosure, to ensure the ambient temperature around the pump does not exceed
40°C, adequate ventilation is required at both ends of the pump. There must be a minimum space of 25 mm between
the pump and the enclosure walls.
3.5

Fill the pump with oil

A hydrocarbon-prepared pump must not be used to process oxygen in concentrations greater than
25% in volume. As there is a risk of fire or explosion in the oil-box of the pump. PFPE-prepared
pumps are available: refer to
Fill the pump with oil as described below. Refer to
item numbers in brackets.
1. Remove one of the oil filler-plugs (6).
2. Pour oil into the pump until the oil-level just reaches the MAX mark on the bezel at the top of the sight-glass (8).
If the oil-level goes above the MAX mark, remove the drain-plug (9) and drain the excess oil from the pump.
3. After a few minutes, recheck the oil-level. If the oil-level is now below the MAX mark, pour more oil into the
pump.
4. Refit the oil filler-plug. Tighten the plug firmly by hand. Do not overtighten.
