Vacuum pumps are used in the degassing of materials such as: silicone, resin, gypsum, and in the impregnation of wood and
other porous materials. These pumps can be widely used in medical equipment, automotive industry, automation, printing
machines, packaging machines, chemical industry.
The series of diaphragm vacuum pumps is characterized by oil-free technology, which allows them to work in clean rooms
where the generation of oil mist is unacceptable. In addition, diaphragm pumps are equipped with filters to ensure the cleanliness
of the exhaust air. They are characterized by stable operation, low noise level, high reliability and long service life. These
advantages allow to use the diaphragm vacuum pumps to cooperate with specialized laboratory equipment, e.g. with the
chromatogram apparatus, and as backing pumps for turbo molecular pumps.
VacuumCahmbers.eu declares that, the ultimate vacuum is below 200 mbar (20 kPa) or 50 mbar (5 kPa) of absolute pressure,
depending on the pump model. The efficiency of diaphragm pumps is 20 l/min, 30 l/min or 60 l/min, depending on the pump
model. Vacuum pump type DVPGM100A also can work as a compressor and allows to generate pressure of 2 bar relative pressure.
Vacuum diaphragm pumps available from VacuumChambers.eu are suitable for continuous operation. The internal cooling
system allows the machine to continuously running for 24 hours.
Vacuum pump is operated in the following conditions: ambient temperature between +5°C and +40°C, air humidity up to 80 %
at 20°C.
The vacuum pump is stored under the following conditions: ambient temperature from -15°C to + 50°C, air humidity up to
95 % without condensation of water vapour.
Diaphragm vacuum pump (Photo 1) consists of:

On the housing (10) of the diaphragm vacuum pump there are: a handle (5) for easy carrying the device, a power switch (2)
and two side covers (3) protecting the pump's moving parts. The pump has an air inlet pipe (7) with a fitting to which a flexible
silicone hose (9) is attached. There is also a pressure regulator (1) and a vacuum gauge (6) on the air intake pipe. The vacuum
gauge indicates the pressure in the air intake hose. Power cord (8) enables to connect the pump to the mains supply.
The vacuum pump type DVPGM100A is additionally equipped with an air exhaust pipe (4) with a fitting to which a silicone
hose can be connected. In this configuration, the pump can work as an air compressor. The air intake and exhaust pipes and fittings
look similar. The pipe on which the vacuum gauge is mounted is the air intake pipe-suction pipe.

Information about the pump type, selected parameters of the device and a warning about the possibility of heating the
housing are placed on the pump housing.
Pumps available from VacuumChambers.eu are equipped with internal sealing made of NBR (nitril butadien rubber) or PTFE
(teflon). Teflon sealing shows better resistance to aggressive chemicals than NBR sealing. Make sure that the sealing material is
suitable to chemicals with which pump is to be used.
A. Pressure regulation.
The pressure regulator has a knob which enables pressure regulation. Obtaining vacuum with the value declared by the
manufacturer requires the tightness of the system. However, when the absolute pressure generated by the device is too low for
the intended process, the pressure regulator knob can be used to unseal the system. This will reduce the efficiency of the vacuum
pump and increase the absolute value of generated pressure. The controller can be used in a situation when, for example: the
pump has a declared ultimate vacuum value of 200 mbar (0.2 bar) absolute pressure, which corresponds to - 0.8 bar relative
pressure, and the required for the process pressure is -0.5 bar relative pressure. The vacuum gauge indicates the current value of
the pressure in the air intake pipe, which allows to control the pressure regulation process.
Turning the regulator knob anticlockwise unseal the vacuum system and decrease pump efficiency - the absolute pressure on
the air intake pipe increases. Turning the regulator knob clockwise seals the vacuum system and increase pump efficiency- the
absolute pressure on the air intake pipe decreases.
Before using the diaphragm vacuum pump for the first time, remove it from its packaging and place it on an even flat surface.
The package also includes a vacuum gauge, power cord and silicone hose. Photo 2 shows the diaphragm vacuum pump and the
elements included in the package loosely. All loose elements should be installed on the pump by the customer in accordance with
instructions below.
Photo 2: Diaphragm vacuum pump with items attached loosely.
The silicone hose (A) should be slipped over the air intake pipe fitting (1a). The hose is flexible and stretches during assembly,
this provides good fit of the hose to the fitting, and ensures tightness of the connection. In the pump model DVPGM100A, the
silicone hose can be attached to the air intake pipe fitting (1a) or to the air exhaust pipe fitting (1b). In the first configuration the
pump can work as a vacuum pump, in the second configuration the pump can work as an air compressor. The silicone hose can
only be connected to one of the fittings at a time. It is not possible to use the pump as a vacuum pump and compressor at the
same time.
The vacuum gauge (B) should be mounted in the vertical threaded hole (2), above the air intake pipe. Screw the vacuum gauge
into the hole by hand until feel resistance. The vacuum gauge should not be tightened too much, as this may damage the threaded
hole. The vacuum gauge has sealing on the thread, to ensure tightness of the connection.
The power cord (C) should be inserted into the socket (3), next to the switch.

A. Vacuum gauge.
The vacuum gauge indicates the pressure in the air intake pipe. For this indication to be correct, it is necessary to unseal the
vacuum gauge. To do this, set the yellow flag of the vacuum gauge (Photo 3), located on top of the gauge, in the open position.
Turn the flag so that the arrow, visible on the flag, points towards the inscription "OPEN". Inscription is visible on the black rubber
plug of the vacuum gauge. Photo 3 B. shows the yellow flag correctly positioned for work. Positioning the yellow flag in the other
direction or toward the word "CLOSE" closes the vacuum gauge, which may result in inaccurate pressure indications.
Photo 3: Vacuum gauge with yellow flag (A. – side view, B – correct setting of the yellow flag during operation).
1) Connect the pump to the vacuum system or to the components it is to work with (the vacuum pump also can be started when
no other components are connected to it).
2) Connect the pump's power cord to the mains supply.
3) Start the pump by turning the switch to the "ON" position.
4) Make sure that the yellow flag of the vacuum gauge plug is in the "OPEN" position (Photo 3 B.).
5) Check the pressure on the vacuum gauge.
6) If necessary, adjust the suction power of the pump using the pressure regulator knob.
Turn the pressure regulator knob anticlockwise to increase pressure in the air intake pipe (reduce pump suction power). Turn
the pressure regulator knob clockwise to decrease the pressure in the air intake pipe (increases pump suction power). The
pressure change is indicated by the vacuum gauge.
For the vacuum pump type DVPGM100A when working as a compressor: Turn the pressure regulator knob anticlockwise to
reduce pressure in the air exhaust pipe (reduce air compression). Turn the pressure regulator knob clockwise to increase
pressure in the air exhaust pipe (increases air compression).
7) After finishing work, turn of the pump by switching its switch to the „OFF” position.
8) If the device will not be used for a long time, disconnect the power cord from the mains supply.
 The device should stand on its feet, on a horizontal and stable surface, in a dry, clean, low-dust and well-ventilated place. The
distance of the side surfaces of the pump from other objects should not be less than 5cm. The distance between the front
and back of the pump from other objects should not be less than 10 cm. If the pump will be installed inside any device or
furniture, provide air inlet to the device from the pump side cover.
 The diaphragm vacuum pump is equipped with an internal cooling system. This allows the pump to run continuously for 24
hours.
 The pump works without oil. Do not fill the pump with oil nor lubricate it, as this may damage it.
 Do not connect to device a pipe with an inside diameter smaller than the fitting inside diameter.
 Do not allow corrosive gases or particulate material to enter the pump.
 If in the pumped gases may be present water vapour, oil contamination or other liquids, an additional filter should be used
to prevent these contaminants from entering the pump.

 The rate of pressure drop during venting gradually decreases. However, if it is not possible to achieve a negative pressure at
the level declared by the distributor, it may indicate the vacuum set leak.
 The efficiency of the device can be adversely affected at high altitudes, due to lower atmospheric pressure.
 If motor fails to start, or it slows down under load, turn it off and unplug it. Make sure that the pump parameters written on
pump housing correspond to the power supply parameters.
 In the event of overheating or noisy work of the pump, stop the pump immediately and check the pump for malfunctions.
 Before perform any service or maintenance work, equalize the pressure inside the device with the ambient pressure. For
example, by disconnecting a vacuum chamber from the pump.
 If the vacuum pump will not be used for a long period of time, cover the pump and then put it in a dry and safe place.
 To use vacuum pump type DVPGM100A as a compressor - connect the silicone hose to the pump exhaust pipe. This allows to
compress blown out air and thus create a pressure. The vacuum gauge, supplied with the device, shows the pressure value
on the air intake pipe. It does not indicate the pressure in the air exhaust pipe. The vacuum gauge is not suitable to indication
pressure higher than 0 bar relative pressure. To indicate pressure generated by the pump it is necessary to install pressure
gauge. The maximum pressure generated by pump type DVPGM100A is 2 bar relative pressure.
 Read the operating manual before use.
 There are warning decals on the vacuum pump. Read them before starting work and follow them.
 Before each use of the vacuum pump, it is necessary to check its technical condition, in particular the power
cord of the vacuum pump.
 Perform servicing and maintenance of the vacuum pump periodically.
 Carry out all maintenance work when the pump is not hot and is not running.
 The general rules for the use of equipment working under voltage must be observed.
 To avoid risk of electrocution do not use this product in area where it could come in contact with water or other liquids.
 Before starting work, make sure that the parameters of the power source correspond to the pump requirements specified
on the pump.
 Do not try to obtain higher pressure or vacuum than those recommended. Refer to the operating parameters given on the
housing of the device.
 Before starting the pump, make sure that pump side covers are free from obstructions.
 Make sure that the pump complies with the technological requirements, processes and purposes for which it is to be used.

Make sure that the inserted filter is clean and completely dry. Installation of a damp air filter may result in corrosion of the
components inside the device. Failures and damage resulting from using the pump with a dirty or moist air filter are not covered
by the warranty.
When the condition of the filter allows its operation, it should be placed in the device where it was previously located. It
should lie flat in the pocket. Its sides should adjoin the devise locally. The filter is slightly deformed during installation. Particular
attention should be paid to whether the filter covers the hole with which the air intake pipe is connected.
Place the sealing plate in the centre of the cylinder housing, make sure that the hole and cuts in the plate are above the holes
in the pump housing. Then place the head cover on top of the sealing plate. The holes in the head cover should correspond to the
holes and cuts in the sealing plate. Reassemble all the screws using an Allen wrench, tighten them until feel resistance.
