Sulzer: Repair of variable speed drives reduces costs and downtime

Thursday, April 20th, 2017 von admin

As the legislation surrounding the efficiency of electric motors continues to tighten, the volume of variable speed drives (VSDs) in service increases. Often specified by the motor manufacturer as part of the original installation – or retrofitted to improve efficiency – the drive contains both hardware and software that is designed to work with a motor in a specific application. So, what happens if the drive ceases to operate? Brian Park, Regional Sales Manager for Scotland at Sulzer, looks at the advancing technology and the maintenance processes that need to keep pace.

Blackmer: Screw Pumps for Bitumen Transfer Applications

Tuesday, April 18th, 2017 von admin

Traditionally used as a cement binder for hot-slab paving, liquid bitumen must be handled at very high temperatures in order to keep it at a workable viscosity. However, even at high temperatures liquid bitumen can be an extremely viscous and shear-sensitive product. Therefore, shipyard operators and tanker owners demand a pumping technology that has been specifically designed to transfer highly viscous liquids over great distances. Realizing the importance for pumping equipment that feature the design and performance characteristics required for transferring highly viscous liquids, Blackmer offers its S Series Twin Screw models for these marine applications.

KSB: New drives reduce variant complexity of pumps

Thursday, April 6th, 2017 von admin

At this year’s Hannover Messe KSB is presenting a new, smart drive solution for fixed speed pumps. With the new MyFlow Drive, which is fully compatible with Industry 4.0, the fixed speed levels at the motor can be set to individual requirements. This provides the user with planning reliability as the flow rate of the pumps can be increased or decreased quickly and easily.

Siemens: Digitalization package for next motor generation

Tuesday, April 4th, 2017 von admin

With the latest generation of its Simotics SD (Severe Duty) motors, Siemens is offering a digitalization package to address the future challenges facing the world of drive technology. The new design is based on a robust, compact gray cast iron lowvoltage motor with high power density. Its future-oriented energy efficiency concept is designed to provide a competitive boost to customers and users. Their extreme resistance makes the Simotics SD low-voltage motors suitable for applications in harsh environmental conditions involving exposure to dust, vibrations or aggressive atmospheres.These benefits make the motors ideal for applications in the petrochemical and general process industries.

Gather: From laboratory to production via pilot plant

Tuesday, April 4th, 2017 von admin

A process generally undergoes initial development within a laboratory and is then made production ready in pilot or mini plants. During this scale-up, a range of different problems can emerge, e.g., in the way temperatures behave. In a laboratory, a process may be endothermic but becomes exothermic in production. How pumps behave in relation to peripheral equipment can change under full-scale production conditions, Sven Borghoff describes a coordinated pump and drive concept which makes scaling up easier.

Dosing pumps with multifunctional extensions for different pump types often used in laboratories generally have no particularly high temperature or pumping ranges. However, when scaling up, these aspects take on major significance. Gather uses its magnetic-driven pumps (Fig. 1) here. They are available in such a broad range that when scaling up from the laboratory to production via a mini or pilot plant, the pumping and control technology can be retained. The company cooperates with the chemical industry, institutes and universities to make process development from initial laboratory trials through to production easier.

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.

KSB motors IE5 classified

Wednesday, March 22nd, 2017 von admin

The KSB SuPremE motor made by the Frankenthal pump manufacturer KSB has been IE5 classified since January 2017. The motor meets the requirements of IE5 (IEC/TS 60034-30-2), the highest of energy efficiency classes for variable speed electric motors; compared with IE4, motor losses are reduced by a further 20 percent.

Unlike conventional synchronous motors this drive is made without any magnetic materials such as rare earths that are categorised as critical raw materials since their extraction causes severe environmental impacts in their countries of origin.

Blackmer: Heavy duty sliding vane pumps for industrial applications

Thursday, March 16th, 2017 von admin

The new GNX and GNXH Series Sliding Vane Pumps are designed to handle a wide range of non-corrosive, non-abrasive industrial liquids and petroleum products. Manufactured with a large operating range, these pumps offer high flows and high pressure. They are currently available in 2- and 2.5-inch flanged port sizes. Larger 3- and 4-inch flanged port sizes will be released later this year. Combined, these sizes provide flow capacities ranging from 20 to 500 gpm (76 to 1,893 l/min) at working pressures up to 175 psi (12.1 bar).
