Installation
When you design your system, take note of the following:
You must be able to isolate the pump from the atmosphere and from your process system if you have pumped
or produced dangerous chemicals
On very dusty applications, incorporate an inlet filter in the inlet pipeline, to minimise the ingress of dust
into the pump
To get the best pumping speed, ensure that the pipeline which connects the process system to the pump is as
short as possible and has an internal diameter not less than the pump-inlet.
Your exhaust pipeline system must be designed so that the pressure in the pipeline during pump operation is
less than 1.15 bar absolute (1.15 x 105 Pa, 862 Torr). If the pressure in the pipeline is higher than this
pressure, the pump will operate at a high temperature and may trip because of excessive electrical current
consumption.
Ensure that debris (such as weld slag) cannot get into the pump during operation.
If necessary, contact Edwards or your supplier for advice on inlet isolation-valves, outlet check-valves or other
components suitable for your application and system design.
3.3 Unpack and inspect
1. Use a fork-lift truck or a pallet truck to place the pallet in a convenient position.
2. Remove the cardboard sleeve which covers the pump, then remove the protective foil bag from around
the pump.
3. Inspect the equipment. If the pump or any of the other items is damaged, notify your supplier and the carrier in
writing within three days; state the Item Number of the pump together with your order number and your
supplier’s invoice number. Retain all packing materials for inspection. Do not use the pump if it is damaged.
4. Check that you have received the items listed in Table 11. If any of these items is missing, notify your supplier in
writing within three days.
5. If the pump is not to be used immediately, replace the packing materials. Store the pump in suitable conditions
as described in Section 6.1.
Incorporate safety devices to prevent operation of the pump when the exhaust pipeline is
restricted or blocked. If you do not, the exhaust pipeline may become over-pressurised and
may burst.
Use suitable lifting equipment to move the pump. If you do not, you can injure yourself or damage
the pump. Refer to Section 2.3 for the mass of the pump.
