+0.7 bar. |
|
Flexibility to alter vacuum
and compressed air capacities to suit individual applications. |
|
High efficiency and low noise
level. Easy servicing and operation. |

Pressure increase by volume reduction is
the principle behind rotary vane operation. |
|
This static design offers excellent service
in pressure, vacuum or a combination of both. |
|
Depending upon size and design - ie. oil
lubricated or dry running - vacuum up to 0.1mbar (abs.)
with capacities ranging from 3 to 1535 m3/hr
and pressure up to 2.0 bar with capacities ranging from
3 to 610 m3/hr can be reached. |

Radial blowers operate using
a dynamic principle; basically, this means that the velocity
of air is changed into pressure. |
|
This method has proved very
successful for the generation of both low vacuum and pressure
combined with relatively large capacities. |
|
Single stage and multi stage
models produce vacuum up to 115 mbar or pressure up to
125 mbar. |
|
Capacities range from 130 to
3,400 m3 /hr. |
|
Radial blowers air-cooled and
non-contact operation means there is no wear, making the
design virtually maintenance-free. |

Two stage liquid ring pumps for high and
medium vacuum with simple and strong construction mainly
used in the chemical, food, pharmaceutical, textile and
palm oil industries. |

The same as rotary vane pumps and roots
blowers the TWISTER screw vacuum pumps use static compression
systems as a design principle. |
|
In contrast to the roots blowers compression
takes place by internal volume contraction. |
|
The TWISTER is suitable for numerous applications,
across many different industries. |

The side channel principle is also based
on the method of dynamic compressions: ie. transforming
flow energy into pressure energy. |
|
The side channel design is suited for applications
requiring both, pressure and vacuum. |
|
Depending upon model and size - single
stage to four stages - vacuum up to 800mbar in suction
operation and pressure up to 1000 mbar in pressure mode
can be obtained. |
|
The capacities range from 16 to 1850 m3/hr.
Non-contact operation means side channel blowers are practically
free of wear and maintenance. |
|
The pumping medium is not contaminated
from carbon dust or oil, as occurs with dry running or
oil lubricated rotary vane pumps. |

Similar to the rotary vane pumps, the rotary
lobe blowers are also static compression systems, although
the compression does not result from an >>internal<<
volume reduction. |
|
Because of the non-contact operation
of the rotary lobe blower, there is no possibility of
contamination of the pumped gas. |
|
The two or three-lobed rotary blower SHARK
is for vacuum operation to 0.5bar (abs.) and pressure
operation to 2 bar (abs.) at capacities of 7 to 8600 m3/hr. |
|
The single stage Roots vacuum pumps VWP
and WKP from Rietschle are designed for use in pump sets
in combination with a rotary vane backing vacuum pump. |
|
The conveyed air is not discharged to atmosphere
but piped into the inlet port of the connected high pressure
stage (rotary vane pump). The achievable capacities range
from 500 to 4000 m3/hr at an ultimate vacuum
of 0.01 mbar (abs.) |

Piston pumps are designed so that they
maintain rated performance throughout their service life.
A stainless steel seal prevents joint leakage from behind
and below the ring. |
|
A corrosion-resistant valve on the piston
pump is design to help maintain pump efficiency by preventing
foreign particles from lodging on valve seats. |
|
Rotary piston type of vacuum pump is motor
mounted or separate drive. |

Rotary piston type of vacuum pump is motor
mounted or separate drive. The motor mounted models are
built directly on the output shaft of the motor. They're
lightweight, compact and designed to fit into small areas. |
|
Where separate-drive models can be operated
in a variety of ways with AC or DC motors, gasoline engines
or from an existing PTO (power take-off). Speed can be
varied from 1000 to 2000 rpm by changing the size of the
drive pulley. |

Available in wide range of
popular voltages and frequencies. |
|
Motor types range from economical
shaded pole to more efficient permanent split capacitor
(PSC) which can also provide improved starting characteristics
for certain applications. |
|
Even at maximum duty, output air
is cool and oil-free. As ambient air enters and
leaves the head, it never goes near the motor to
pick up heat and foreign matter. |
|
Diaphragm type is easy maintenance;
all that needs to change is the air filters, just
a 60-second screwdriver job to get inside. |
