Heat transfer oil circulation pump acc. to DIN EN 733

Saturday, December 9th, 2017 von admin

Fig.1 The new NKX heat transfer oil circulation pump

The pump manufacturer Dickow has developed a new pump line NKX for circulation of thermal oil. The pump casing is designed for 16 bar and 350 °C. The new pump line extends the application limit of the previous NKLs-type. The new NKX will replace the series NKLs with exactly the same dimensions in future.

The NKX is used as a circulation pump for hot oils in industrial heating plants/units. The performance range covers capacities up to 400 m3/h and differential heads up to 90 m in 50 Hz services; and capacities up to 2,500 US-gpm and differential heads up to 400 ft in 60 Hz services. The dimensions and performance range of these centrifugal pumps are according to DIN EN 733, that means range is subdivided into different pump sizes in order to achieve best efficiency for all service conditions inside the envelope.

An ‘alignment free’ pump

Wednesday, November 29th, 2017 von admin

It is imperative that pumping systems are designed and operated in a way that reduces the amount of harmful stress placed on components. One area that has been difficult to achieve and maintain is shaft alignment. Failure to properly align a pump’s mating shafts will eventually lead to challenges associated with shaft fatigue and failure, resulting in compromised pumping-system uptime, reliability and safety. This can then result in costly maintenance or even knock the pump out of service and halt production.

Focused on this problem, Blackmer developed GNX Series sliding vane pumps, which are called by the manufacturer “industry’s first alignment-free”. It is a reduced-speed pump for use in both portable and stationary applications.

Klaus Union: New twin magnetically coupled screw pump acc. API 676

Thursday, September 21st, 2017 von admin

With the proven Klaus Union magnetic drive and a modular design, the pump manufacturer offers a highly flexible and robust seal-less magnetically coupled twin screw pump: the SLM DSP-2C. Due to its seal-less design and leakage-free operation, it is especially suitable for applications in the chemical and petrochemical industry.

Due to its robust design and leakage-free operation, the new Klaus Union twin screw pump series SLM DSP-2C meets precisely these requirements. For this purpose, the pump manufacturer takes advantage of the established in-house modular pump system, which has proven itself for many years in the complete magnet drive pump range consisting of the pump hydraulic, magnet coupling and bearing bracket. High interchangeability and availability of spare parts as well as customisable suction and discharge flanges guarantee maximum flexibility to meet project requirements.

Wilden: 13 mm (½”) Clamped Metal Pump

Friday, September 1st, 2017 von admin

This 13 mm (½”) clamped metal AODD pump PS1 is equipped with the energy-efficient Pro-Flo Shift Air Distribution System and its clamped configuration allows for easier maintenance, diaphragm replacement and cleaning.

The footprint of this AODD pump matches that of the Wilden PX1, which enables direct replacement of a PX1 with no repiping necessary. With less components and 7% more efficient than the PX1, the backward capability of the PS1 makes it an easy way to enhance and upgrade existing pump performance.

Netzsch at drinktec: New design of hygienic rotary lobe pump

Wednesday, August 23rd, 2017 von admin

The new design of the Tornado rotary lobe T.Sano has a completely smooth housing compared to the previous model, which attracts barely any dirt or dust. The range of the  rotary lobe pump T2 all-metal is interesting for food manufacturers due to its lack of dead space and also due to its oil-free design and operation. This pump is driven by a tooth belt drive, whereby the lobes are simultaneously synchronized. This technology is absolutely oil-free and maintenance-free.

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.
