9. If warm cooling air from vacuum pumps is used in air heating systems, e.g. to warm up a
workroom, take precautions against air pollution and possible contamination of the
breathing air.
10. Do not remove any of, or tamper with, the sound-damping material.
11. Never remove or tamper with the safety devices, guards or insulation fitted on the
machine.
12. Do not change the purpose of the pump. If the pump is configured to be used as a
vacuum pump, do not use the pump as an overpressure pump. If the pump has
been configured to be used as an overpressure pump, do not use the pump as a
vacuum pump.
13. Never run the overpressure pump without the air intake filter mounted. For the
vacuum pump, Quincy recommends to install an air intake filter to safeguard the
pump. Consult Quincy to check whether the application for the vacuum pump
requires and air intake filter. Never remove or tamper with the safety devices.

What is vacuum and how is flow rate understood
What is vacuum and how to denote
A vacuum is any pressure in a system that is below the ambient atmospheric pressure.
It can be denoted in absolute terms or in effective (gauge) terms:
• Mbar (a) - Absolute pressure - denotes how much the pressure is above absolute zero
vacuum.
• (minus) mbar(e) - The Effective or Gauge pressure - denotes how much the pressure
is below local atmospheric pressure
(1)
Pressure
(2)
Absolute vacuum
(3)
Typical QCV/QCLP claw pump working range 600 mbar(a) (450
Torr(a)) – 150 mbar(a) (112.5 Torr(a))
(4)
Atmospheric pressure
Atmospheric pressure at sea level is roughly 1 bar or 1000 mbar (750 Torr). A typical
working range for the QCV/QCLP claw pumps is 600 mbar(a) (450 Torr(a)) to 150
mbar(a) (112.5 Torr(a)). From the illustration it can be seen clearly that this range is
also equivalent to - 400 mbar(e) (-300 Torr(e)) to - 850 mbar(e) (-637.6 Torr(e)).
It is important to understand which type of reference is required before selecting a
pressure instrument for measuring the vacuum. It must be noted that the distinction doesn't
matter for a pressure difference (delta P; for example, pressure loss), since it is always the
result of subtracting 2 pressures (whether stated as absolute or effective pressures).

Section II - General description
11
Flow rate definitions
There are two common but different ways to denote flow rate in vacuum. The first one is
based on the displacement or volumetric flow rate and the second one is based on the
throughput or mass flow rate. Quincy’s vacuum pumps use volumetric flow rate to
denote performance, the unit being Am³/hr.
Displacement/volumetric flow rate
For the relevant pressure range, when a QCV/QCLP claw pump operates at quasi
constant motor speed (rotations per minute) and since the compression chambers have
fixed dimensions, the same volume of air is pumped from inlet to outlet with falling
pressure level. Over the relevant pressure range, this makes the volumetric flow rate
quasi-independent of the vacuum level. It is the expression of the flow rate inside the
piping at the governing vacuum level (Am³/hr), and always higher than the throughput in
mass flow rate.
Throughput in mass flow rate
Even if the volumetric flow rate is quasi unchanged with falling pressure level, the
number of molecules in that pumped volume is not. By definition: the deeper the
vacuum, the lower the amount of molecules in the same volume of air. This means that
the mass flow will decrease with decreasing (absolute) pressure. It is clear that a flow
rate must be stated at a certain vacuum level when using this denotation.
Introduction
The QCV/QCLP series claw pumps are single-stage, dry vacuum and overpressure
pumps driven by an electric motor. The vacuum and overpressure pumps are air-
cooled.
The pump is designed to be run as a vacuum pump or an overpressure pump
dependent upon its configuration.
The pump is specifically designed to work with clean air, inert gas or small amounts of
water vapor. The ambient temperature must be between 0 °C to 40 °C.
These pumps are enclosed in a sound-insulated bodywork to aid noise reduction,
cleanliness and heat transfer.
The QCV/QCLP claw pump robust design ensures complete flexibility and quick access
to all parts. The claw pump mainly includes dry claw element, gearbox, electric motor
and drive train all mounted on a common base frame.
Element
The pumping chamber consist of duplex set of rotating claws / rotors on cantilevered
shafts. The two claws and the cylinder are all non-touching but have accurate
clearances to allow a very efficient performance.
The main chamber is completely lubrication free and designed with corrosion resistant
materials. The whole assembly is referred to as an element.
Inlet non-return valve
Inlet non-return valve prevents reverse flow of inlet air and thus prevents reverse
rotation of the pump.
Gearbox
The element is driven through an oil lubricated gearbox housing synchro-meshing gears
which in-turn is coupled to a direct drive motor.
Electric motor
Electric motors are 3 phase ‘multi voltage/multi frequency’. For 60Hz supplies they are
cUL/UL approved. The main motor options are:
 200/230V 50/60Hz

Section II - General description
12
 400V 50Hz
 380V 60Hz
 500V 50Hz and 575 60Hz
 460V 60Hz
 230/460V 60Hz (Optional)
The motors are suited to operate with Variable Speed Drive to have complete
controllability and to reduce power consumption. This efficiency improvement leads to
power reduction and consequently a lower carbon footprint. Following standard features
provided with the pump:
 Vacuum relief valve (In case of vacuum pump)
The relief valve is designed to open at a predetermined set pressure to protect the
pump from damage.
When the vacuum level is exceeded, the relief valve opens and allows air to enter
the pumping chamber. This has the effect of internal cooling.
 Intake filter (In case of overpressure pump)
Intake filter prevents foreign material from entering the pump. Abrasive, bulky
material will damage the pump’s internal parts and could cause catastrophic failure.
 Silencer (Extra inlet silencer in case of overpressure pump)
The pump inlet and discharge can be noisy. The pump is equipped with an outlet
silencer.
For the overpressure pump an extra inlet silencer is installed.
 Pressure Safety valve (In case of overpressure pump)
A pressure safety valve automatically releases air from a pump, when the pressure
exceeds preset limits.
The following features are available as an option:
 Humid Option (In case of vacuum pump)
‘Standard’ and ‘Humid’ versions are available dependent upon the harshness of the
application.
The harsh applications, generally wet application need more protection for the pump.
‘Humid’ version contains advanced corrosion resistant wetted parts.
In addition to this, pump is provided with inlet liquid separator, condensate drain
facility and corrosion resistive coating to the exhaust to withstand the harsh
applications.

Flow diagram
Flow diagram - QCV 045, QCV 110, QCV 220 Dry claw vacuum pumps
Vacuum Pump
Air comes in through air intake and non-return valve arrangement and displaced by the
vacuum pump element.
After passing the element, the air enters the discharge silencer before exiting to the
atmosphere.

Section II - General description
17
Flow diagram - QCLP 110, QCLP 220 Dry claw overpressure pumps
Over pressure Pump
Air comes in through air inlet filter and silencer. The air flows through the non-return
valve which prevents reverse flow of air to the inlet. The air is compressed in the
element and exhausted at pressure through the pressure port.
Ensure that the safety valve at the outlet is correctly installed and adjusted.

Section II - General description
18
Cooling
Pump cooling
The pump is cooled by forward curved fan located within the coupling housing. This
provides air flow around the pump to aid cooling. The cooling fins also radiate the heat
away and the motor fan cools the drive motor.
The gearbox oil is cooled down by recirculation and convection from the fan.
In many cases the process gas can also cool the element.

Drain port
A port (1) at the base of the exhaust silencing chamber allows draining of the
condensate.
Humid versions of this vacuum pump may have a manual drain valve / tap installed to
facilitate easy draining.
From factory this drain point is sealed with a threaded plug, but can be exchanged by a
connector with tube to drain the condensate.
Consult local regulations which are applicable for water drainage.
