Hydraulics & Pneumatics Features

Customer ‘wish list’ pushes design boundaries

“A solution looking for a problem” is too often the way new products and technologies reach the market. How creative could a company be if they knew in advance what customers really wanted and invented products to meet those needs? Richard Bull describes his company’s strategy to do just that.

Leak-proof connections for vacuum pumps

In the creation of a high vacuum, oil-free membrane units act as auxiliary backing or ‘roughing’ pumps, while turbo molecular pumps perform the final compression.

Drill tool could enhance oil recovery from existing wells

A novel oil drilling tool, currently under development at SINTEF Petroleum Research in Norway, has characteristics that will enable it to take on a number of different tasks.

Material switch tackles premature seal failure

Kalrez Spectrum perfluoroelastomer O-rings from the DuPont Performance Elastomers range have been successfully used to minimise the risk of premature seals failure, as well as increasing MTBF and significantly reducing the incidence of downtime for hydraulic clamping systems.

Misting pumps fire the imagination(21/11/2012)

John Dennis Coachbuilders (JDC) has introduced a new fire-fighting system based on Cat Pumps’ high pressure triplex plunger pump technology. Providing effective control of brush and grass fires, as well as incidents in industrial premises, the vehicle-mounted JDC Wildfire Attack System uses Cat Pumps’ 5CP Series for generating a fine mist foam and water fire suppressant.
Closed-loop hydrostatic drive proves an efficient muck shifter!(21/11/2012)

Green Cove Springs, Florida based Vac-Con is one of the USA’s largest manufacturers of drain cleaning equipment, and its Combination Cleaning Machines are the most popular products. These combine a high-pressure water jet pipe cleaning system with a vacuum system to remove accumulations from sewers and storm drains.
Compact high pressure gear pumps(07/09/2012)

Simple yet highly reliable the Viking External Gear Pumps include models which provide flows from as little as 0.2 lit/min up to 760 lit/min.
Miniature valves are big energy savers(08/08/2012)

The TwinPower valve from Bürkert uses rocker technology rather than the more familiar plunger type actuation and has two compact coils that operate the valve with a minimal holding current, effective after just 100ms, the result is a 75 percent reduction in energy usage. Two models are available, the smallest measuring just 10 x 20 x 44mm (WxDxH).
Hydraulic upgrades: the business benefits(02/08/2012)

Hydraulic systems as old as 50 years may still provide good service; but while this is evidently testament to their quality of manufacture and durability, current technology has transformed the performance of modern hydraulic power transmission systems in terms of their efficiency and productivity.
