Eaton pumps-up lead-time muscle in EMEA

20 June, 2014

Eaton has made a significant investment its manufacturing capability in EMEA. The company claims this will enable it to meet ‘industry-leading’ delivery times for its X20 pumps range. Eaton’s X20 pumps are used in wheel loaders, agricultural vehicles and road sweepers as well as other mobile and marine applications. The investment of more than €2.4 million will enable the localisation of a regional assembly and test programme for X20 piston pumps at the Eaton Havant UK site, with the aim of providing customers with a ‘best in class’ delivery lead time across Europe, the Middle East and Africa. Mark Foreman, plant manager, said: “We are expecting to see an upsurge in demand for open circuit piston pumps in the next few years as the manufacturers of original equipment increase production to meet their orders. Normally, this would mean that lead times would increase for products such as the X20 pump but this investment means we can actually reduce lead times to approximately half that which is industry standard now.” Rick Jacobs, president of Eaton’s hydraulics business for EMEA commented: “[The new investment] will offer a huge advantage to Eaton’s customers in EMEA. By significantly reducing lead times on the X20 pumps we will play a major role in helping manufacturers fulfil their order books and the quality and robustness of our technology, plus our ability to provide a global after-sales support network, gives companies across EMEA a superb choice.” www.eaton.com/hydraulics


Moog extends radial piston pumps range

20 June, 2014
Moog, designer and manufacturer of high performance motion control solutions, has extended its range of variable-displacement radial piston pumps, with the RKP 250 for displacements up to 250 cm³ per revolution. The largest pump in Moog’s RKP series, the RKP 250 is intended for applications requiring high system pressures, such as metal forming, presses, injection moulding and other types of industrial machinery. It is capable of delivering continuous pressures up to 350 bar (5000 psi). The Radial Piston Pump is known for its robust design and reliability even in extreme environments. For machine applications where even higher displacements are required, the RKP 250 can be configured in a double-pump arrangement with full torque available across all displacements up to 500 cm³. It also can be combined with other RKP pumps and pumps with standard SAE interfaces (A, B, and C). All RKPs have short axial dimensions, making them ideal for compact multi-pump arrangements. Highly dynamic control The RKP 250 provides highly dynamic control of hydraulic flow and pressure. Designed to be used in open-circuit systems, its large suction port and flow-optimized suction path ensure robust suction behaviour, a high speed limit and low noise emission. The pump has a maximum speed of 1800 rpm at an inlet pressure of 0.8 bar absolute (11,6 psi abs), enabling it to operate in machines located at high altitudes without the need for a pre-load pump. The new piston pump incorporates a nine-piston rotary group. The design of the pistons provides a very low pressure ripple and noise emission behaviour. Robust control system As with the smaller models in the RKP range, the RKP 250 is equipped with Moog’s proven, robust control system with a sliding stroke ring. The exclusive use of ferrous metals with hardened, wear-resistant contact surfaces leads to outstanding longevity in use. Special versions are available for use with water-glycol (HFC) and synthetic esters (HFD) fluids. An RKP-D version of the pump, with highly dynamic electro-hydraulic control of flow and pressure through advanced digital on-board electronics, can be configured easily with the Moog Pump Configuration Software. Status information, set values and actual values are displayed graphically for quick and easy performance monitoring, troubleshooting and tuning. As part of Moog’s modular design concept, various compensator options are available including: Pressure (F2), combined pressure and flow (R1), fixed displacement (B1), and dual displacement (N1) compensators. The RKP 250 will also be available in explosion-proof versions. www.moog.com


Customised valve actuation – when standard products are not the answer (June 2014)

02 June, 2014
The overriding majority of valve actuation applications in today’s industries are fulfilled with standard products. In some cases an actuator may need to be modified to suit specific operating requirements, but here again a solution based on a standard product can usually be found. There are occasions, however, when the physical and operational demands of an application rule out anything other than an entirely customised approach to the problem. The long-standing experience of Rotork-Hiller in the fluid power and motion control industries has been mostly built on the provision of actuators for critical and vital applications calling for the design and manufacture of solutions to suit customers’ individual requirements. Unlike other manufacturers therefore, customised valve actuation is the cornerstone of the company’s activity. Among many examples, an actuator recently built in compliance with customer specifications serves as a practical illustration of this activity. The specification called for a self-contained electro-hydraulic modulating actuator to operate a three-way globe bypass valve within a reactor water chemical clean-up system. This was a non-safety related application, but the specification also dictated a strict weight limitation and a maximum overall dimension envelope. Rotork-Hiller engineers put together a package incorporating all the requirements, including a number of components manufactured uniquely for the application. Meetings with the customer and design reviews enabled modifications to be made during the production process until the compact final package was completed. One of the engineers closely involved with the project takes up the story: “Everything was achieved in a timely fashion during which we designed and built a prototype for proof of concept and life testing in only six weeks, prior to design modifications and final design approval. The design demanded a lot of project specific direction to produce a modular electro-hydraulic actuator with a wide range of linear travel and thrust outputs. The lightweight and compact design delivers a highly accurate and responsive modulating performance and incorporates an intelligent positioner with HART communication protocol. “The complete package was successfully tested to industry standards for Electromagnetic Compatibility (EMC) at an independent laboratory. The project illustrates how Rotork-Hiller is willing to go the distance and provide customer service at a level that is exemplary.” www.rotork.com


Amarinth wins its first order from Ineos for flare knock-out pumps

30 April, 2014
Amarinth – the company specialising in the design, application and manufacture of centrifugal pumps and associated equipment to the Oil & Gas, petrochemical, chemical and industrial markets – has won an order from Ineos to supply two API 610 OH2 pumps with Plan 53B seal support systems for the flare knock-out system at the Ineos onshore refinery at Grangemouth, Scotland. The mercaptan oxidation (Merox) process at the Ineos Grangemouth plant required two API 610 OH2 pumps to remove the condensate that collects in the flare knock-out drums during the refining process. The pumps would only be operated infrequently, sometimes being dormant for weeks, but would then have to start reliably on-demand when the trigger level in the knock-out drums was reached. The Grangemouth refinery is situated next to the sea and so the pumps would be exposed to the often hostile Scottish elements. Ineos also had stringent site specifications that had to be met as well as needing the pumps on a tight 33 week delivery. Amarinth designed the pumps to withstand temperatures of -20C for the coldest of Scottish winters. The pumps were also painted to offshore specifications to survive the harsh coastal saline environment. Due to the low usage of the pumps, special oilers were incorporated so that any water in the bearing oil could be easily identified and removed. To ensure reliable on-demand operation, Amarinth worked with Ineos to develop a specific maintenance schedule for the pumps to minimise the risk of damage caused during the periods of inactivity, particularly around preventing the seal faces sticking. Given the demanding requirements, Ineos also wanted to ensure that Amarinth could provide support on-site for the pumps and so Amarinth sent its trained site engineers to Grangemouth to carry out the installation and commissioning of the pumps. Oliver Brigginshaw, managing director of Amarinth, commented: “We are delighted with this first order from Ineos, which allowed us to apply our extensive offshore experience to this order despite it being an on-shore application. We are noticing more customers requesting on-site commissioning when they place their orders and this provides us with useful feedback from site when we send our trained engineers to carry out this work which we can then incorporate into future designs and enhancements. It is also encouraging to see that the levels of opportunity within the UK offshore and on-shore markets continue to remain buoyant.” www.amarinth.com
