2 PRODUCT SPECIFICATIONS

2.1 Pump description

PHV K pump series are rotary vane oil lubricated two stage vacuum pumps.

The flanged electric motor is coupled by means of an elastic coupling.

The cooling is made by means of forced air by a centrifugal fan.

At the inlet there is a mesh filter in order to protect the pump from solid parts.

An integrated non-return valve prevents the oil from going back and the return of air in the camber to be pumped

down during the stop phase.

PHV K Series

4 Doc. n. LI 3488.00 ENG (translation)

The separation of oil smokes from discharged air takes place in the TMF oil mist filter (optional). The filtered oil is

recovered automatically by the pump by precipitation (this take place when the machine is not working or during its

operation at the maximum vacuum, i.e. inlet is closed).

A three position adjustable gas ballast valve prevents the condensation inside the pump when small vapour quanti-

ties are sucked.

Pumps starting from size PHV 120 are equipped with a water cooling circuit.

2.2 Expected use

The vacuum pumps described in this manual can pump only air and small quantity of water vapour.

They are suitable to evacuate closed systems or to operate at a constant vacuum till 1x10

-3

mbar.

The ambient temperature and the inlet temperature must be included between 12 and 40 °C. In case you get tem-

peratures outside this range, please get in touch with us.

The suction or other types of gas or vapours must be declared in advance to P.V.R. that will give the conformity to

the specific use.

2.3 Forbidden use

ATTENTION:

It is forbidden to suck through the pump:

Liquids or solid substances;

Dangerous, explosive or aggressive gas and vapours;

It is forbidden to use the discharge of the pump to create even limited pressures.

It is forbidden to install the pump in a potentially explosive ambient.

2.4 Protections

The pump must be protected against suction of dust and liquids.

For applications where this protection is not warranted it is recommended to install a pressure gauge on the oil tank

for a visual control of the oil separator blockage.

The pump is supplied without control panel. The electric motor must be protected according to the regulations in

force.

ATTENTION:

In case of applications where the pump stop or failure can cause damages to people or things, safety measures for

the system must be provided.

by coming into contact with hot surfaces. The pump can be placed inside other machines by adopting the neces-

sary safeguards. Before carrying out any maintenance on the pump, be sure the pump is cold.

HARMFUL SUBSTANCES EMISSION

The discharged air contains part of traces of oil mist. Check the compatibility with the work environment. A failure or

the seals wear can cause an oil leakage. Avoid the dispersion to the ground and the pollution of other materials. In

case air containing dangerous substances must be pumped down (for example, biological or microbiological

agents), adopt filtering systems before introducing air in the work environment.

Used oil coming from the pump must be disposed of in accordance with the regulations in force in the Country of

use.

Do not dispose into the environment.

HAZARD CAUSED BY VACUUM

Avoid the contact with the pump inlet port during the pump operation.

Introduce air in the inlet circuit before every operation.

The contact with parts under vacuum can cause injuries.

HAZARD CAUSED BY PRESSURE

The pump tank is pressurized. Do not open the oil filling and discharge plugs during operation.

FOR A SAFE MAINTENANCE

All maintenance operations must be carried out with the pump idle, disconnected from the electrical supply, with

the pump cold, vented to atmospheric pressure. Prevent unexpected start-up (e.g. block the power switch with a

personal lock).

ELECTRIC SAFETY

Some components of the electric equipment are electrically charged during operation whose contact may cause

serious injuries to persons or objects.

Connection and control of the electric system must be carried out by skilled personnel only.

The electric equipment must comply with the EN 60204-1 standard and with the other laws in force in the Country

of use.

Besides, electric equipment must comply with EN 61000-6-4 and EN 61000-6-2 standards concerning electromag-

netic compatibility and electromagnetic immunity for industrial environments.

PHV K Series

ENG (translation) Doc. n. LI 3488.00 9

FIRE HAZARD

The use of the pump for situations unforeseen or not recommended by this manual, as well as lack of correct

maintenance, may create high risks for overheating or fire.

In case of a fire do not use water to extinguish but use a powder CO2 extinguisher or other means compatible with

the electric equipment and lubricating oil.

4 TRANSPORT - HANDLING

4.1 Lifting

The orientation of the packed components must correspond to the instructions given by the pictograms on the ex-

ternal covering of the packaging.

For the unloading use a lifting equipment suitable for the pump weight.

Use the suitable lifting eyebolts to lift the pump.

4.2 Unpacking and components control

When receiving the machine, check that the packing is intact or if is shows signs of damages occurred during

transportation.

If there is no damage, proceed to the unpacking and check further the machine.

In case damages are found, inform immediately P.V.R. and the carrier.

4.3 Storage

The pumps must be stored or transported without oil and protected from the atmospheric agents at a temperature

between -15°C and 50°C (normal humidity rate).

5 COMMISSIONING

5.1 Location

The pump must be installed in a protected area (see safety rules).

It must be fastened with support feet on horizontal plane.

It must be accessible for correct and easy maintenance, by respecting the minimum distances from possible

obstructions.

It must be accessible to suitable lifting equipment.

Ensure the change of air in the room or inside the machine where the pump has to been installed. To assure a

sufficient cooling, avoid to overpass 40°C of ambie nt temperature.

The pump must be protected against jets or sprays of water that may penetrate the tank through the exhaust

port.

Whenever the pump is installed outside, it must be protected against atmospheric agents and it must be used
