Tube pumps suit low to medium viscosity liquids

Model
TPU tube pumps are ideally suited for liquids of low to medium
viscosity.Aalborg has announced that its model TPU tube pumps are ideally suited for liquids of low to medium viscosity.

Chemically resistant tubing materials and new peristaltic pump-head technology combine to meet the demands for reliable, long-term pump operation.
Model TPU tube pumps are ideally suited for liquids of low to medium viscosity.

Liquid pumps designed for oil, water and chemicals

Autoclave Engineers has designed a group of air-driven, positive-displacement, high-pressure liquid pumps for service with oil, water and chemicals.

The ASL Series is available in a variety of drive ratios and includes single and double air-drive designs that are capable of up to 60,000psi (4135 bar).

Manual options are available in the ACHL Series pump line and AHL Series double-acting, double air-drive pumps are designed for a combination of high flow and high pressure.

Features include: pressure maintained without energy consumption; requires no lubrication; and external spool valve for easy maintenance.

Applications include: pressure-test stands - stationary and mobile; component and vessel testing; burst testing; umbilical testing; lubrication; bolt tensioning; hydraulic-control panels; chemical injection; and hydrostatic testing.

MCP concept addresses hard-soft contact needs

A concept for the sustained assessment of sliding surfaces based on Merkel Counter Surface Parameters (MCPs) takes into account the specific requirements involved in hard-soft contacts.

Seal counterfaces have usually been assessed on the basis of parameters for metal-to-metal contacts.

However, as a piston and rod seal in hydraulic systems always involves a hard-soft contact, the result obtained for counter-surface assessment in terms of abrasivity, long-term behaviour and oil deposits provides restricted information.

This is leading to greater friction and more rapid wear of the sealing elements in tribological systems.

With MCPs, surface profiles are registered according to the tried-and-tested contact-stylus process.

Maintenance Saving Trap – Eeze

http://www.engineeringmaintenance.info/images/stories/Valveforce%20j%20peg.jpgValveforce 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.

Metering valves cut lubricant consumption by 25 per cent on linear guidance systems

SMDS metering valvesBy 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.

External gear pumps are the most popular pumps used in modern hydraulic systems

Hydraulic SystemsThese 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.
