MATCH HOSE MATERIAL TO PUMPED FLUIDS

FIVE NEW HOSE MATERIAL immersion sample packs are available to Bredel and APEX pump users.

Watson-Marlow Fluid Technology Group (WMFTG) is offering the packs as a way of matching Bredel hose material to the fluid being pumped, which, if completed correctly, is proven to reduce costs.

In tough fluid-handling applications, optimised pump life and efficiency depends on selecting the right hose material. Matching the peristaltic hose material to the pumped fluid can reduce downtime, cut production costs and save energy in pumping operations that involve viscous and abrasive fluids.

Each Bredel hose features a precisionmachined natural rubber outer, with intermediate compound layers, bonded by multiple nylon cord reinforcements to add strength and flexibility. However, it is the critical inner hose material that must be selected to match the fluid as each Bredel hose bore material has specific attributes for abrasion resistance, along with differing suitability for oils and greases, acids, alcohols, strong oxidising products and many other substances.

The sample packs carry complete hose material data, including temperature resistance, as well as instructions for immersion tests.

HIGH-FLOW ATEX EX100/140 PUMPS

THE NEW PIUSI EX100 AND EX140 pumps with ATEX and UL certification, which are available from Bell Flow Systems, have been developed to meet the requirements of various fuel transfer markets. The maximum safety has been applied to these pumps when dealing with potentially explosive atmospheres or flammable fluids. Both the EX100 and EX140 are sturdy and versatile, mainly developed for the heavy-duty transfer of kerosene, petrol and diesel fuel. They are simple to use, as well as compact and versatile. Their adaptability means the pumps can be used for their chosen applications in most working conditions.

Offering high and constant flow rates, even in complicated delivery systems, they are high performing pumps that can work without interruption because of their capability to operate continuously.

EFFICIENT SELF-PRIMING PUMPS FOR IMPROVED PERFORMANCE

THE HYGIENIC, SELF-PRIMING, LKH Prime 40 pump from Alfa Laval not only offers high energy efficiency and versatility, but it also allows for significantly reduced noise levels and easy maintenance. Performance has been increased, allowing the pump to reach a flowrate up to 110 m 3 /hr and head of 115m. These results have been achieved thanks to a combination of advanced air-screw technology and optimised impeller and casing geometry.

The pump shares common parts with the Alfa Laval LKH range and is EHEDG certified and authorised to carry the 3-A symbol. It has been designed for cleaning-in-place (CIP) duties containing entrained air, and can also pump product, potentially reducing the capital investment when designing process systems – whatever the industry.

MECHANICAL SEALS GAIN IECEX APPROVAL

AESSEAL has achieved a world’s first with the recent introduction of its IECEx compliant short canister mixer seal (SCMS) range of mechanical seals.

SINCE THE ORIGINAL INTRODUCTION of the SCMS mechanical seal range it has evolved from being available only as a double seal to being configurable as either a single or double seal.The range has also, literally, grown in size, from the original offering for shaft diameters of up to 220mm, in both liquid lubricated or dry contacting versions. The mechanical seals find applications in a broad range of mixer, agitator and reactor applications and are suitable for side entry (flooded) or top entry (running in vapour) mounting.

The original SCMS was ATEX Zone 0 certified for use on systems in explosive atmospheres, but of course this certification is only applicable within the EU. However, in 2016, the global IECEx certification was expanded beyond its original remit for electrical goods to include non-electrical products. AESSEAL responded quickly to this change and, early in 2017, the company began work to have the SCMS verified as meeting the IECEx standard.

Working alongside CML, an independent notified body, over an 18-month period detailed design documents were scrutinised. The seals were tested under arduous operational conditions and risk assessment procedures verified.

The result of this work is that AESSEAL is now able to offer what it believes to be the world’s only mechanical seal that is both ATEX and IECEx certified. This affirms the AESSEAL SCMS range as suitable for use in hazardous locations around the world where flammable liquids, vapours, gases or combustible dusts have the potential to cause a fire or explosion.

Traditionally, it has been the responsibility of customers to carry out the IECEx verification process themselves, so the availability of pre-certified seals can offer significant savings in time and investment for customers as they no longer need to do this.

Luke Farmer, Technical Manager for AESSEAL, said: “AESSEAL’s professional identity and pride is rooted in investment, innovation and customer service, combined with a strong commitment to responsible manufacturing and environmental sustainability. This ethos informed our SW2/3 water management seal support systems – which recycle flush water rather than discard it – a product which can lead to a potential saving of 6.3 million litres of water, per pump, per year.

“It also led to our F-range of mechanical seals – developed in direct response to EU regulations governing food contact materials (FCMs), which require full traceability of raw materials. These ensure that customers in the food and drink and pharmaceutical sectors can be confident that their mechanical seals comply with Regulation (EC) 1935/2004 on FCMs and pose no risk of contamination on production lines. The ATEX and IECEx verified SCMS range is another important step in our innovation journey.”

WIRELESS CONDITION MONITORING

SULZER HAS ANNOUNCED THE introduction of Sulzer Sense, a wireless IoT condition monitoring system. The solution includes wireless sensors that can be attached to a pump, agitator, motor or any rotating equipment. The sensors measure temperature and vibration and send the data to the cloud. This means that the operating status of the equipment can be remotely monitored 24 hours a day, seven days a week. Sulzer Sense devices are battery-powered, and they operate in a wireless mesh network, making them easy and cost-efficient to deploy and operate.

The condition monitoring feature identifies changes in condition parameters and indicates potential faults at an early stage. The new devices will detect possible imbalance, misalignment, looseness and bearing wear. This supports predictive maintenance and helps to avoid sudden pump failure and eventual downtime.

Data captured by the system is sent to the cloud and can be monitored on a mobile, tablet, laptop, etc. through the company’s online service – virtually anywhere and anytime. Users of the system can set an alert value and will automatically be notified if this value is exceeded without the need for manual measurement.
