KTR: Pump coupling for explosive atmospheres

Monday, March 9th, 2015 von admin

ktr-3The jaw geometry of the Rotex Non-Sparking consists of a conductive high-tenacity plastic that is injected onto the hub body which continues to be made of steel or other metals such as aluminium. The newly developed synthetic material prevents any static charging and is also designed to be so hardwearing that even in cases of elastomer wear out, torque will still be transmitted without any danger of sparking. As a result, maintenance work can be postponed to a convenient time frame. The failsafe and maintenance-free Rotex Non-Sparking is certified under EU directive 94/9/EC (ATEX 95) and thus deemed suitable for the use in explosive atmospheres.

Oerlikon Leybold Vacuum: Atex Certificate for Steel Degassing Vacuum Systems

Tuesday, July 1st, 2014 von admin

OLV PIC 2 (2)In all processes for steel degassing under vacuum gases and vapors are formed that might be dangerous. Essentially CO and H2 as well as the vapors of volatile metals are released from the steel surface. Explosion protection in vacuum plants especially those that generate a large quantity of CO by the use of oxygen for decarburization so far has been assured by overpressure flaps at the metallurgical reaction vessels, alarm devices for water leakage, sensors for pressure and temperature as well as emergency venting with nitrogen. With the introduction of mechanical vacuum pumps efficient installations for gas cooling and dust separation became necessary.

Mouvex: Eccentric disc pumps in oil & gas industry

Monday, January 13th, 2014 von admin

Mouvex Pompe  A 31Mouvex A Series eccentric disc pumps are now available in ductile iron construction – a critical upgrade as more companies in the oil & gas industry are integrating ductile iron systems into their processes. Additional upgrades to Mouvex’s A Series pumps includes the implementation of ISO PN16/ANSI 150 flanges while offering both Mouvex or standardized mechanical seals, which helps expedite installations regardless of location. A Series pumps also doubled its maximum differential pressure from 5 bar (72 psi) to 10 bar (145 psi), enabling it to be used in the safe transfer of viscous, non-lubricating, volatile or delicate fluids in a variety of oil & gas applications.

Mouvex: Eccentric Disc Pumps for Isocyanates

Saturday, February 2nd, 2013 von admin

Mouvex_SLC-Series

Isocyanates require a pump that handles product gently (low shearing), has strong suction capability, and offers a low-maintenance wear-compensation design. The SLC Series Eccentric Disc Pump features superior suction at low speeds, ensuring minimum product is left in the piping prior to maintenance. The design of the SLC Series allows the pump to self-compensate for mechanical wear, giving the eccentric disc pump the ability to maintain consistent flow rates over time.

Hermetically sealed twin- screw pump with magnetic coupling

Thursday, March 22nd, 2012 von admin

A hermetically sealed twin- screw pump expands the comprehensive product program from  Bornemann. This is a pump with contactless rotating elements and media-lubricated bearings, which can also be used with media that are low-lubricating. The pump is hermetically sealed by a magnetic coupling. As such, the advantages that speak in favour of using a “seal-free” pump can now be combined with the advantages of the proven Bornemann 2-spindle technology. A version is also optionally available with mechanical seal, for extreme application conditions.

Flotronic: Pump machined out of a solid block of PTFE

Monday, January 30th, 2012 von admin


The UK-based specialist pump manufacturer Flotronic already had a solution to aggressive chemicals handling requiring a high flow rate – the Chemflo. The challenge was to produce a cost-effective pump that could handle aggressive chemicals and other products at lower flow rates.  The new pump also needed to transfer material at temperatures up to 80°C and be ATEX-compliant and ultra-safe. The turning point in developing a solution came from a simple enquiry. Could a pump be machined out of a solid block of PTFE? And so the ‘Minichem’ was born –a n air-operated double diaphragm pump, machined from one solid block of PTFE.
