Valveforce launched a new range of compact steam trap set stations to provide easy to maintain cost effective solutions to help Maintenance Engineers work quicker and more efficiently on their steam trap sets.

At the core of the Trap-Eeze station is the MK 45 steam trap which features a hastalloy sensing element which ensures NO loss of live steam and incorporates a two bolt fixing of the cover which provides quick in line access to the trap element and ensures a low maintenance requirement.

By incorporating special lubricant metering discs on its range of linear recirculating roller bearings and guideway assemblies, Schaeffler has reduced lubricant consumption by more than 25 per cent compared to conventional designs.

A range of linear recirculating roller bearings and guidance systems are now available with special lubricant metering valves, which provide precise doses of lubricant to the linear guides, reducing lubricant consumption by more than 25 per cent compared to standard designs, reducing maintenance and servicing costs and preserving resources for the customer.

These external gear pumps feature versatility, strength and long useful life.Their simple construction ensures limited purchase costs and servicing. Thanks to these basic concepts, together with ever-improving product design and features, research-based on many years of experience, accuracy in material selection, production process followed in great detail and tests on mass-produced parts, our gear pumps have reached top quality standards.

For this reason, our products can work under heavy operating conditions and transmit high hydraulic power. Furthermore, Marzocchi pumps feature good hydraulic, mechanical and volumetric efficiency, low noise level and, last but not least, compact dimensions.
Generally these gear pumps usually consist of a gear pair supported by two aluminum bushes, a body, a securing flange and a cover.
Shaft of the driving gear projecting beyond the flange mounts a twin-lip seal ring (the inner lip being a seal and the outer being a dust seal). An elastic securing ring secures the ring in place.

Running over 1,700 kilometres from the Mediterranean Ceyhan terminal through 3 countries to the Caspian Sea the new BTC (Baku-Tibilisi-Ceyhan) crude oil pipeline presented some new technical challenges for electro-hydraulic actuator specialist Midland-ACS.

The company has been manufacturing remote actuated valves for oil and gas applications for over 20 years, but the

Over the last few months the main topic on the lips of business and world leaders has been the current economic climate and how its affecting them. For others its brought about an increased focus on delivering on and above their intentions, as well as setting themselves apart from the crowd, disproving the detractors and creating solutions in opposition to the world

Hansford Sensors Ltd. now offer a range of submersible vibration sensors, which has been specifically designed for operation in partial or complete immersion in water, making them ideal for the monitoring of pumps in a maintenance role.

Pumps perform important tasks across many industries, some operating continuously and others triggered into action to move liquids at specific times or as a result of leakage.

One of the challenges facing plant instrumentation engineers today is the effective and reliable monitoring of thrust bearing wear in critical pump applications.  Typically pumps of this type are in continuous use and operational downtime is normally only permitted during planned outages.  Predicting the wear and hence requirement to replace the thrust pads, is essential to fit in with this regime.

 With rotational speeds between 3000 and 7000 RPM, protection against potential pump damage is also key, as excessive thrust wear can not only damage the bearing assembly but also the impeller, resulting in the plant potentially being out of action for 6 months or more.

Eliminating areas which might increase the potential for bacteria growth such as traps and crevices is an important design requirement for control valves used in aseptic applications, such as food processing and pharmaceutical production. Control valves which have smooth, cavity-free internals also helps to promote effective CIP and SIP (Clean or Sterilised in Place) and also aids self-draining.

SAMSON CONTROLS offer a range of valves which incorporate these features and are manufactured to quality assurance systems certified to ISO 9001 whilst also meeting stringent FDA requirements. 

Hayward Tyler Group, a leading manufacturer of glandless motor/pumps for power generation, oil & gas, nuclear and subsea applications, is using the latest 3D modelling and finite element analysis (FEA) software to accurately predict overall stress distribution for complete motor pump assemblies, resulting in reduced engineering lead times for its customers.

Hayward Tyler Inc. (HTI) Engineering recently invested in COSMOSWorks Professional, a software package that includes a Pressure Vessel Design Study option, which is being used in combination with 3D solid modelling software from Solidworks.
