The 4th generation of screw compressors
BOGE has recently launched the fourth generation of series S into the market via the S-4 models. The new screw compressors will be available with motor powers of 110, 132 and 160 kW for the time being – optionally as a basic compressor with integrated gearbox, directly coupled or directly coupled with frequency control. Moreover, BOGE provides the types with 110 KW as other variants – with gearbox and dryer, directly coupled with dryer or directly coupled with dryer and frequency control. Depending on the type the models operate at a maximum pressure between 7.5 and 13 bar reaching an effective volume between 5.5 and 27.6 m3/min. Other S-4-models sizes 55 to 110 kW as well as types with a direct drive and integrated gearbox are to follow with the next stage of development.
Heart of the S-4-series is the „IntegrateDrive“ compressor stage with integrated gearbox. By using a bellhousing made of nodular iron gearbox and and motor shaft are optimally and solidly aligned to each other. The two shafts are connected via a fail-safe coupling series POLY-NORM AR. The shaft coupling damping torsional vibrations is suitable for axial plug-in, easy to assemble and maintenance-free with short dimensions.
Mobile pump for petrochemistry compliant with ATEX
The mobile pumps of company Börger are used in various fields: No matter if used in an oil refinery or chemical plant, with sewer renovation or in the flood area. Here each mobile power pack is produced for the respective application.
This mobile pump for petrochemistry is a special solution with both the pumps and control technology as well as the base frame with forklift pockets being supplied by the company Börger. The mobile pump is used for recirculation work and residual draining of storage tanks in areas with potentially explosive atmospheres. Naphta and various kinds of petrol are conveyed. A BLUEline rotary pump size FL 518 is used here. The pump is conveying between 20 and 100 m³/h with a differential pressure of up to 6 bar. The power pack is driven by an I. C.-engine having a power of 22 kW.
Motor and pump are connected by a double-cardanic ROTEX ZS-DKM-H with split hubs easily compensating for the temperature-related fluctuations in the system. The jaw coupling damping vibrations is made of cast iron and the hubs are divided into two halves by precise cracking. This results in an uneven surface with a positive fit ensuring an accurate fit of both halves. This production technology lays the foundation for a better ease of assembly specifically with narrow conditions. At the same time it allows for a good access to the spider: There is no need for time-consuming disassembly of adjacent components.
High-performance machinery for agricultural irrigation
Euromacchine S.r.l. is an Italian manufacturer of motor pumps and systems for agricultural irrigation. The portfolio includes mobile and stationary pump assemblies as well as accessories for individual adaptation of pump units.
The mobile stations are equipped with I. C.-engines of various well-known manufacturers. A tailor-made flange coupling type BoWex-ELASTIC HE3/HE4 is installed between engine and centrifugal pump connecting the engine flywheel to the pump shaft. The highly flexible coupling has variable-speed properties compensating for displacements and reducing critical torsional vibrations. It is assembled following the plug & play procedure: In this case the coupling merely needs to be fixed to the engine flywheel and the hub has to be shifted onto the pump shaft.
In contrast to that a flexible ROTEX coupling is used on the electrical self-priming pumps between electric motor and pump shaft. The jaw-type coupling is characterized by small dimensions, low weight and low mass moments of inertia while transmitting high torques ensuring a power transmission damping torsional vibrations.
RS-PRO screw compressors – compact, high-performance and tough
RENNER Kompressoren provide compressed air systems for industry and trade. The product portfolio includes screw compressors, piston compressors and oil-free SCROLL compressors as well as units with frequency control or direct drive.
Oil-injected screw compressors covering a defined power range allow for a state-of-the-art and highly efficient kind of compressed air generation. RENNER is dedicated to this compression principle. The screw compressors with asymmetric profile are designed for powerful industrial operation. When developing the new “RS-PRO” and “RSF-PRO” series the focus was placed on powerful compressed air supply with few space required and easy access to the maintenance parts. As an example, the model series “RSDKF-PRO” is equipped with compressed air receivers, frequency control, pre-filter frame, refrigeration dryer and electronic control RENNERtronic. The performance range extends from 5.5 - 11 kW with a final pressure up to 15 bar.
For cooling compressed air and hydraulics a double-circle cooling system series MMC by KTR is used mounted between compressor and compressed air receiver. Our specialists of the business unit »Engineered Business« account for the selection.
All-rounder centrifugal pumps by C.D.R.
The product portfolio of the Italian pump manufacturer C.D.R. Pompe S.r.l. includes magnetic couplings and centrifugal pumps with shaft seal used both in the chemical and pharmaceutical sector and refinery industry, technical textile industry and water treatment.
Series CCL covers a horizontal, single-stage centrifucal pump coated with nylon with shaft seal in a block design or free shaft end. The sealing pump is supplied completely with bottom, joint, coupling cover and electric motor and is suitable for corrosive, aggressive and hazardous liquids such as fertilizer processing, biodiesel, air treatment and desalination. In order to be suitable for high performance as well, the series is equipped with a special bearing support.
The torsionally flexible shaft coupling type POLY-NORM AZR is mounted between motor and centrifugal pump combining the driving shaft with the pump shaft. The fail-safe coupling is equipped with a spacer ensuring replacement of the flexible coupling element without dismounting pump or motor from the base plate.

Rotary vane pumps for miscellaneous applications
Leybold GmbH based in Cologne is part of the Atlas Copco group providing vacuum solutions for production and analysis procedures as well as for purpose of the research. The portfolio includes oil sealed slide vane rotary vacuum pumps used in all sectors of vacuum technology. They serve for pressure generation in the low vacuum and fine vacuum range or as a backing pump in combination with Roots pumps or high vacuum pumps. Slide vane rotary vacuum pumps are available as a single-stage or double-stage type the ultimate pressure range of which is different depending on the type. These pumps include, among others, series TRIVAC B.
The standard types of series TRIVAC B from D 4 B to D 25 B are available with 1- or 3-phase motors. The D 40 and D 65 B pumps are equipped with 3-phase motors. Apart from that all pumps of series B can be obtained without a motor. A flexible ROTEX coupling is used between motor and pump. The compact jaw coupling is characterized by small dimensions, low centrifugal moments with transmission of high torques ensuring power transmission while damping torsional vibrations.
