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.

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.
