From pipe to component ready for installation

Thursday, April 12th, 2018 von admin

Individually produced, made to measure, in very small quantities or as a series – for years Butting from Knesebeck in Germany has been well known as a reliable supplier of special components ready for installation. In the course of time, countless product variations have been developed and manufactured together with the end customer – sometimes in series production.

True to the motto “more than pipes” the longitudinally welded stainless steel pipes from Bunttings in-house production usually serve as primary products for the components ready for installation. Corrosion resistant pipes, manufactured specially for the individual customer order, are used to produce these components. Thus special sizes or particular tolerances can be taken into account, such as production by internal diameter.  As part of prefabrication, laser, welding and forming technology are possible, as are cutting and surface processing by grinding and blasting, and combinations of these.

Twin screw pumps for food applications

Wednesday, March 21st, 2018 von admin

Hyghspin twin screw pumps have a compact design and many versatile and flexible uses. The design of these pumps do follow hygienic design criteria. Their block construction saves space and always ensures a correctly aligned coupling.

Mobile units including frequency converter and service switch are another feature of this pump range. These units stand out, among other things, on account of their self-priming qualities and ease of service. Safe-to-run dry seals, for example, require no flushing.

Flotronic: The One-Nut Design for hygienic AODD

Tuesday, March 28th, 2017 von admin

UK specialist pump manufacturer Flotronic Pumps Limited was founded by Lew Norris in 1981. The engineering design consultancy ‘Norris Brothers’ had been involved in the design of  specialist pumps since 1952.  Lew Norris’ new company pioneered the air-operated, double-diaphragm ‘One-Nut’ pump. Flotronic’s ‘One-Nut’ design allows quick pump disassembly for inspection, cleaning and maintenance – delivering a massive benefit for pump users in terms of reduced down-time, particularly as the pump can be inspected or maintained in line without disconnection of pipework. Flotronic remains the only British-owned specialist manufacturer of air-operated, double-diaphragm pumps in the UK.

Lewa: Safe pumping of sour crude oil

Thursday, May 7th, 2015 von admin

SauerölpumpeCritical applications of conveying mixtures of acidic hydrocarbon/water to the washing system are a challenge for any pump manufacturer. This was also the case in one recent project Lewa handled in the Emirate of Abu Dhabi. Lewa have designed and supplied 16 pumps to a major construction company in Abu Dhabi specifically designed to handle this critical application. Two processes required to pump

  • liquid hydrocarbons from the flare knock-out drum or the blow-down drum respectively and
  • convey the acidic hydrocarbon/water mixture back into the oil line to the washing system

Since the differences in these two processes are only minor, it was possible to supply 16 mechanically identical pumps of the Ecoflow series, driven by 55 kW electric motors.

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.
