SECTION II. GENERAL
1. PRINCIPLE OF OPERATION
This diagram shows a typical internal vane vacuum pump which consists of a motor-driven
cylindrical rotor eccentrically mounted within a larger housing or stator. Two spring-loaded
vanes are mounted in the rotor, parallel to its axis, in diametrically opposed slots. The vanes
bear against the wall of the stator under spring pressure and centrifugal action. The eccentric
mounting of the rotor provides a permanent point of contact between the stator and rotor and
divides the stator in two sections: intake and exhaust. A thin film of oil at the point of contact
maintains effective vacuum sealing, thus preventing the passage of gas between stages.
Two openings in the stator serve as gas intake and exhaust ports. The intake port (1) is
connected to the system to be evacuated.

Feature Outline
HYPERVAC® 31000-31500 Direct Drive Vacuum Pumps
are a series of two stage state of the art mechanical high vacuum pumps designed for economy and durability. Large pump oil reservoirs coupled with high
pump rotor speeds ensure superior performance and fast recovery times. These six models in the 3000 series are excellent for distillation, filtration,
lyophilization, degassing, drying electrophoresis gels, electron microscopy, vacuum deposition, and as a roughing pump for high vacuum systems. All
models are supplied with a gas ballast which consists of an adjustable valve which permits a controllable proportion of air to be bled into the exhaust stage
for rapid purging of entrained condensable vapor in the pump oil. This valve can be operated in a totally closed position to achieve maximum vacuum. The
pumps also have an anti-suckback valve enableing isolation of the pump from evacuated system after pump is turned off or in event of power failure. All
pumps are very quiet in operation.
2. UNPACKING
a. Carefully remove the pump from the shipping case. Examine motor and pump thoroughly to be sure it was not damaged in shipment. Preserve
all paper work and inspection tags for future reference. If damage has occurred from shipment a claim must be filed with the carrier immediately. Preserve
the shipping container for inspection by the carrier. If you are required to communicate with your dealer or with HYVAC PRODUCTS be sure to include your
order number, pump model, serial number and date of purchase for quick identification. Do not return the pump to the factory without first obtaining an
(RGA) Return Good Authorization form and shipping instructions from HYVAC PRODUCTS, INC.
b. Check nameplate rating of the motor. Voltage and frequency must match the power source. The motor horsepower speed and rotation must
be suitable for the intended use.
c. Inspect and Remove all shipping tags, shipping caps, shipping gaskets and plugs. Retain and keep with pump literature.
3. PUMP LOCATION
The pump should be located in a clean and well-ventilated area. Adequate space should be provided for routine maintenance such as oil changes. Above
all, the pump should be located as closely as possible to the system being evacuated in order to utilize it most efficiently. The shorter the inlet connection
length the more efficient the pump will operate. Its location should include such determining factors as the length and size of connections, the number of
bends and the type of exhaust connections.
4. ELECTRICAL POWER
Review the power source and the motor rating to be sure they agree in voltage, phase and frequency. Motor thermal overload protection is made available
by the motor manufacturer as an aid to minimizing motor failure. It is strongly suggested that you familiarize yourself with the protection supplied with your
motor so that you may react accordingly in the event of an emergency. Automatic protection of the motor is designed to reset itself after a predetermined
cooling period. If the fault to the drive remains unaltered, the motor will cycle on and off until the fault is corrected. The motor data plate will indicate the
presence of thermal protection.
5. EXHAUST PROVISIONS
Exhaust connections will be determined by the type of system to be exhausted and the desired cleanliness of the atmosphere surrounding the pump. Under
normal conditions of mild evacuation nothing more than a 90-degree pipe will be necessary to cover the port. Where relatively high gas flows are involved or
6
where the presence of oil vapors is objectionable an exhaust filter may be fastened to the exhaust port in place of the dust cup. The optional exhaust filters
used on our pumps are capable of absorbing and restricting any vapor particle larger than 0.1 micron. Exhaust filters of this type are designed to pass no
more than 21 parts per million of vapor particles larger than 0.1 micron. Where extreme exhaust conditions are encountered it is best to pipe the exhaust
directly out of the building or to an exhaust hood.
6. VACUUM CONNECTIONS
The choice of connections and fittings can have a very marked effect on the pumping speed at the vacuum chamber. Any connection placed between the
pump and the chamber creates impedance to the flow of gas. This is particularly true at low pressures in the millitorr range where the gas flow is molecular
in character. The gas flow is then dependent upon the kinetic activity of the molecules to bring it to the intake of the pump. It has been shown that the
conductance of a tube is proportional to the cube of its diameter and inversely proportional to its length. Therefore, it is imperative that the connecting lines
be as large in diameter and as short in length as practical. For best results the diameter of the connecting tube should be at least as large as the diameter of
the pump intake.
7. TYPE OF LUBRICANT
All HYVAC mechanical vacuum pumps are tested with HYVAC oil and shipped with a supply of oil. HYVAC oil has been especially prepared and is ideally
suited for use in mechanical vacuum pumps because of its desirable viscosity, low vapor pressure and chemical stability. The vacuum guarantee on all
HYVAC pumps applies only when HYVAC oil is used. Please refer to back page for more information on the various HYVAC vacuum pump oils available.
SECTION III. OPERATION 1. STARTING PROCEDURES
Before attaching the pump to a system it is well to familiarize yourself with the function and action of the pump, which you have now acquired. Remove the
intake and exhaust port plugs and temporarily provide a stopper for the intake and install exhaust dome provided for the exhaust. Review the power
requirements as described earlier. The amount of oil suitable for efficient and satisfactory performance should be determined after the pump has reached its
operating temperature. Initially, however, the pump should be filled with fresh oil while the pump is idle. Fill the pump until the oil level falls just below the
"MAX" point on the sight glass window. In general, the oil level will be higher during high-pressure operation. Mechanical pumps will gurgle in varying
degrees under four conditions of performance:
a. When operating at high pressure as in the beginning cycles of evacuation of a chamber.
b. When the oil level in the pump reservoir is too low.
c. When an air leak is present in the system being evacuated.
d. When the vented-exhaust valve (gas ballast valve) if present, is open.
Awareness of these possibilities will save time in setting up a system. The best performance of a mechanical pump is generally obtained after sufficient time
has been allowed for the pump to come to operating temperature. Take every precaution to prevent foreign particles from entering the pump. A fine screen
is provided for this purpose in the intake passage of HYVAC pumps. Vacuum Inlet Traps are available from HYVAC PRODUCTS, INC. and are suggested.
When water or solvent vapors are expected in the air stream, a cold trap from HYVAC PRODUCTS, INC. is recommended to condense the vapors before they
enter the pump.
2. SHUTDOWN PROCEDURES
A few simple precautions are all that is necessary when a shutdown is in order. If a vacuum gauge is connected to a system, first isolate the gauge, then
turn off the power and open the system to atmosphere. If the pump is removed from the system, cover the intake port with a rubber stopper or suitable cover
to protect the pump against contamination and loose particles. If the pump has been contaminated in service, even slightly and is going to be shelved for a
prolonged period, it is best to drain the oil, flush with HYVAC flushing oil and refill with a fresh charge of HYVAC Oil.
SECTION IV. MAINTENANCE 1. OIL CHANGES AND OIL LEVEL
7
a. DRAINING THE PUMP An oil change is best accomplished when the pump is warm and the oil is less viscous or thick. Use a container large enough for the oil in the particular
pump. Stop the pump and open the drain valve. A thorough job may be accomplished by tipping the pump slightly if this is possible. The residual oil may
be forced out by operating the pump briefly with the drain plug removed, intake port open and exhaust port closed, or the pump could be drained by turning it
over manually and pouring out the oil. If the desire is for an oil change not a cleaning, also use HYVAC Oil to refill.
b. FLUSHING AND DECONTAMINATING THE PUMP When the drained oil is found to be contaminated it may be necessary to flush the pump. After removing all the oil, as in step "a." above, close the drain and
pour HYVAC Flushing Oil into the intake port. Open the exhaust port and operate the pump for about 25 minutes with the intake port alternately opened and
closed to agitate and circulate the fresh oil. Again stop the pump, drain the flushing oil and force out the residue as before. The amount of flushing oil and
the number of flushes will be determined by the extent of contamination and the color of the oil. Higher vapor pressures present in other types of oil may
cause difficulty later in the attainment of a high vacuum.
UNDER NO CIRCUMSTANCES SHOULD ANYTHING OTHER THAN HYVAC FLUSHING OIL BE USED FOR FLUSHING A MECHANICAL PUMP.
c. REFILLING THE PUMP After you are satisfied that the pump has been thoroughly flushed, refill the pump by pouring new HYVAC Pump Oil into the oil fill or exhaust port. Fill to the
indicated level in the sight glass and start the pump with the intake closed. A gurgling noise is characteristic when high-pressure air is drawn through the
pump. It should disappear quickly as the pressure within the pump is reduced. Do not over-fill the pump with oil. This may cause excessive splattering of oil
through the exhaust port. After the pump is warmed up, check the oil level again and adjust if necessary.
2. PREVENTATIVE MAINTENANCE
If the pump uses a Sleeve-Bearing Motor:
a. Re-oil annually after the second year of service to extend motor bearing life for normal duty.
b. Re-oil more frequently for continuous severe duty operation.
c. Re-oil every two years for light intermittent duty and at least every five years for light occasional duty.
d. Add up to 3 drops of an SAE 10 oil.
3. REPAIRING OIL LEAKS
Oil leaks may develop wherever two mating faces are sealed with a gasket. Such seams may fail as the result of deterioration of the gasket material,
loosening of the screws caused by temperature variations, or improper care as the result of previous reassembly. Typical gasket seams in a mechanical
pump are located at the shaft seal, the oil drain, and the mating faces of the oil seams. When a small oil leak is observed the pump may be operated
satisfactorily for some time without loss of function. Eventually, of course, a great loss of oil may cause harmful damage or pump seizure. An oil seam may
be sealed by any of several methods. When an O-ring is employed, the surfaces of the O-ring and its groove should be wiped clean. If the O-ring is not
badly deformed or scratched it may be reused by sealing with a slight film of vacuum oil. A thin rubber gasket is used to seal oil cage mating surface. A
replacement joint of this type should be thoroughly cleaned of all old gasket material and the mating surfaces cleaned of any nicks.
Locate carefully the new gasket between the sealing surfaces, (no sealant required). Tighten the mounting screws uniformly and refill the pump with HyVac
Oil.
PREVENTATIVE MAINTENANCE
Change the pump oil on a regular basis. If the pump uses a sleeve bearing motor re-oil annually after second year of service to extend motor bearing life.
After an oil change check the pumps vacuum pressure with a thermocouple or McLeod type vacuum gauge on a semi-annual basis.
4. VACUUM PUMP PROBLEMS
Failure to Attain Vacuum
Leakage, contamination and unusual out gassing are the general causes of problems associated with poor vacuum. To operate at
maximum efficiency a system must be leak tight and completely clean. Often, poor system performance is related to system leaks, (not
pump malfunction) that cannot be overcome by the capacity of the vacuum pump in service.
If the system is completely clean and free from leaks, and unwarranted vacuum problems still exist, the pump should be checked. A
simple test for the condition of a mechanical pump is a determination of its ultimate pressure capability. This can be accomplished by
attaching a vacuum gauge directly to the pump at the pumps intake connection. This is often referred to as the blank off pressure. The
gauge may be any suitable type provided consideration is given to the limitations of the gauge being used. If the pressure is unusually
high, between atmosphere and 1 Torr, the pump may be badly contaminated, low on oil or malfunctioning. On the other hand, if the
pressure is only slightly higher than the guaranteed pressure of the pump, an oil change may be all that is required.
Leak Detection
System leaks often are a root cause of high system pressures. It is important to understand the concepts available for determining leaks
and finding them. For large leaks, pressurize the system with a small amount of air pressure. Paint suspected area with a thick soap
solution. Escaping air will produce soap bubbles just like the tire on your car. For metal piping and seal leaks, place a thermocouple gauge
between the vacuum pump and the suspected leak area. Spray suspected area with acetone and observe any sudden increase in
pressure on the gauge. This is observed if a leak is present (use extreme caution since organic solvents such as acetone are highly
8
flammable and combustible). For very small or molecular sized leaks it is advisable to employ a specialized piece of equipment known as
a helium leak detector.
Oil Contamination
Another common cause of loss in efficiency in a mechanical pump is contamination of the oil. It is often caused by the condensation of
vapors and by foreign particles. The undesirable condensate emulsifies with the oil which is recirculated and subjected to re-evaporation
during the normal cycle of pump activity thus reducing the ultimate vacuum attainable. Some foreign particles and vapors may form sludge
in the oil, impair sealing and lubrication and cause eventual seizure.
Therefore, periodic oil changes are necessary to maintain efficient operation of the system. The required frequency of changes will vary
with each particular system. Experience with the individual process will help determine the normal period of operation before an oil change
is required.
Damage to Vacuum Pumps
There are three common causes of damage to vacuum pumps. All involve ingestion of foreign materials into the pump. They are gross
contamination of the oil with condensable vapors such as water vapor, contamination of the oil with acids and other reactive chemicals,
and ingestion of dusts or other solids into the pump mechanism. Most of these materials are generated within the vacuum system itself.
Therefore, when setting up a new vacuum system or troubleshooting an existing system, it is critical to identify the presence of such
materials and take steps to eliminate them from the gas stream being ingested into the pump.
There are several methods for eliminating damaging materials from a vacuum system. A combination of these methods is often
recommended for best results. They are use of an appropriate vacuum trap or combination of traps, frequent oil changes, and use of the
vacuum pump's gas ballast valve which acts as a vented exhaust valve.
