Pumps and Valves

A Low-Lead Brass body (LLB) series of solenoid valves has been designed by parker Hannifin for applications in the beverage dispensing industry. Designed for fitment into coffee machines, drinks vending machines and automatic water dispensers, the valves feature stainless steel pilots. They have many potential uses in dispensing systems, including: boiler water-loading control, steam control, cold, hot and superheated water shut-off, cold water and steam mixing and steam pressure control.

As frequent failures can occur on the centrifugal pumps for water recirculation of a large CHP (combined heat and power) plant in Romania, the company asked NSK and its local distributor to perform an on-site bearing investigation. The outcome identified poor lubrication of the pump bearings as the source of the failures, with NSK recommending the adoption of sealed-for-life bearings featuring DDU seals and high-temperature grease.

A University of Huddersfield professor has collaborated with and a world-leading engineering firm as part of the latest research project which has been hailed by a Government body. Professor Rakesh Mishra, an expert in fluid dynamics, has formed a sequence of Knowledge Transfer Partnerships (KTPs) with Weir Valves & Controls UK, part of the UK-based multi-national Weir Group. The projects have led to massive sales increases and cost savings.

Various models of the Extrema submersible wastewater pump from T.I.P. (Technische Industrie Produkte) are now available at Conrad Business Supplies. All pumps feature a robust stainless steel motor housing, a water-cooled motor and self-lubricating precision ball bearings, as well as thermal overload protection.

The latest release from Intertronics, the preeflow eco-PEN330 volumetric dosing pump, offers manufacturers precision application of fluids and pastes from a minimum of 0.002ml, at rates of up to 3.3 ml/min. The preeflow progressive cavity pump technology handles delicate fluids from watery up to a pasty consistency without damage, and since the system is both temperature and input pressure independent it can provide ±1% accuracy and better than 99% repeatability.

COVAL has entered a new phase with the LEMAX, after the launch of the LEM, a new generation mini vacuum module integrating, in a smaller size, all the functions of the vacuum pump. The emphasis with this new product is on energy saving through continuous monitoring and regulation.

Over 40 years ago now, Ted Fort OBE, who has recently become an octogenarian, started buying Okuma machining centres and lathes for his company, Fort Vale Engineering, and now it is a global market leader for the manufacture of stainless steel valves and ancillaries used in the tank container industry for transportation of bulk liquids and gases by road, rail and sea.

Compressed air is sometimes referred to as the 4th utility. In many sectors of industry, it is as important to the viability of an operation as electricity or water. For this reason, it is important to pay the same degree of attention to the optimisation and correct operation of pneumatic systems as to other utilities, for cost, performance and reliability reasons.

Designed for low and medium viscosity liquids, Intertronics have launched two non-contact jetting valves. The Vermes MDS 3010+ and Vermes MDS 3020+ microdispensing jetting valves are designed for precision dispensing of material in small volumes at fast speeds with extremely high accuracy and repeatability.

A major update to the ASCO Numatics G3 Series electronic valve island platform has been announced by Emerson, which enables a reduction in installation costs. The valve island has been expanded so that it can control up to 128 solenoid valves on a single valve island assembly. This allows more valves to be controlled from a single node, enabling savings in the number of nodes and the cabling, internal tubing and electrical connections in the cabinet.
