Whatever the field of engineering, James Walker has ranges of products and services that solve static and dynamic fluid sealing problems, reduce plant downtime, improve operator safety and enhance environmental efficiency.
Our constant programmes of research and development have perfected new materials and provided the latest generations of high technology fluid sealing products. They exceed the expectations of design engineers, plant operators and maintenance staff throughout industry today.
Relevant products and services include:
Our family of hydraulic sealing products covers virtually every hydraulic application. Ranges of rod/gland seals, piston seals, wipers and bearing strips suit the most accurate instruments and control actuators up to the heaviest extrusion and forging presses, jacks and cylinders. All these products are designed and proven to give optimum equipment performance with long trouble-free operating life.
Over seven million 'O' rings of inch and metric sizes are held in stock for immediate delivery. We precision mould 'O' rings in over 100 general and high performance elastomers, and are also UK authorised distributor for Kalrez® perfluoroelastomer 'O' rings and other fluid handling parts manufactured by DuPont Performance Elastomers. In addition, our commercial grade 'O' rings, 'O' ring cord and 'O' ring kits are suitable for duties where our top grade products are unnecessary.
We produce precision cut gaskets to any shape, size or quantity from any sheet material using CAD/CAM abrasive waterjet cutters or laser cutters. Our jointings include a full range of top value compressed fibre grades, Supagraf® expanded graphite, Fluolion® Integra White & Blue stabilised PTFE, plus Nebar® cork-elastomer grades. Gaskets from all these materials are used worldwide for OEM and plant maintenance applications.
Metakamm® Kammprofile type gaskets and Metaflex® spiral wound are widely specified where temperatures, pressures, flow rates and vibration are beyond the capability of conventional flange jointings. Likewise, our Moorside® API and ASME ring joints solve flange jointing problems with high pressure/temperature pipework.
Our vast range of compression packings caters for all known operating conditions with valves, rotary and reciprocating pumps and similar plant. Exfoliated graphite packings, such as Supagraf® Control and Supagraf® Premier packings are proven for fugitive emission control in valves. In addition, many of our multi-service packings - such as Liongraf and Fluolion®Emulsion 2XA - are renown for long trouble-free operation in pumps and valves handling steam, fuel oils, process water and highly abrasive fluid media.
The Walkersele® family of radial lip seals provides customers with a vast combination of lip profiles, materials and construction to protect bearing assemblies on rotating shafts and rotary plant. We mould Walkerseles from 10mm up to unlimited diameter. Using our patented Walkersele® OSJ-2 on-site joining technique, the seals can be fitted without plant stripdown.
We constantly develop and exploit new high performance elastomers that have improved resistance to chemical attack, abrasion or extremes of temperature/pressure. These materials are supplied as precision moulded components, extrusions, sheeting or rubber-to-metal bonded parts for our customers to use within their own assemblies.
We have vast experience in the design and manufacture of customised and standard components in many exotic materials - as well as more general polymers such as nylon, polyurethane and PTFE. Our facilities enable us to produce parts in small batches up to millions, using techniques such as plastics moulding, casting, machining and bonding.
Comflex expansion joints cover all duties and temperatures from -60°C to well over +500°C. Applications include gas turbine exhausts, hot air ducts, fans, boiler side walls and exhaust gas ducts. Our flexible bellows protect components from abrasive environments and retain lubricants on duties ranging from hydraulic rams to machine slides, and valve stems to screw threads on precision equipment.
Tico® Pipe Grips and Clip Strip will mount and support pipework at up to 300°C - they dampen vibration, allow for thermal movement and provide galvanic insulation. Tico®Slide Bearings allow movement with stable support for mechanical systems and pipework.
Our highly developed machinery mounting pads provide safe and sure support for presses, machine tools and other plant, plus isolation from shock, noise and vibration. By bonding pads to the floor, customers can avoid mechanical fixings and retain layout flexibility. The Adjustamount® system also allows plant height, gradient or level to be precision adjusted.
Treadmaster® safety flooring products provide comfortable, slip-resistant surfaces for industrial environments. These products are widely used for catwalks, machine and assembly shops, plant rooms and works offices, as well as public areas.
RotaBolt® stud and bolt tension monitoring systems are accurate to ±5%. These are used across all industry sectors where the failure of a bolted system could have serious health & safety, environmental or financial consequences. RotaBolt® tension control is recommended for structural, mechanical and flange tightening applications.
Our CAD/CAM controlled abrasive waterjet cutters and state-of-the-art laser cutters produce complex precision-cut profiles in any sheet material - swiftly, economically and cleanly. Cutting capability includes stainless steels - from foil thickness up to 100mm - as well as titanium sheet. We work from customers' CAD files via email, or by digitising templates, samples or drawings.
On-site maintenance and workshop-based refurbishment of valves, pumps, hydraulic systems and other plant is a key service we provide. Skilled craftsmen at our dedicated workshops use the best equipment, materials and components for these projects, and all plant items are tested and certified before re-installation. Our on-site staff are fully experienced and hold safety passports.
