5 most important factors to consider for hydraulic fittings
OEMs and fitting manufacturers are constantly finding new ways to stump us with different threads and new ways to seal them. Generally, however, when making hydraulic fitting connection choices today, there are several features to research and understand for your application. Kyri McDonough from the Hose Products Division at Parker Hannifin runs through the connections, attachment styles, and the five most important factors you need to consider for hydraulic fittings.

Mini pumps for air or gases
KNF diaphragm mini pumps and compressors are highly customized “built-to-suit” pump solutions benefiting OEMs. These mini pumps (N85-N815 Series) can reliably handle gases, take samples (even liquids in a vacuum), or evacuate vessels. They are typically used for analyzers, medical instruments, printers, and in other applications requiring high performance in a compact package. Depending on model, standard mini pumps can provide flow rates up to 20 l/m, achieve up to 27 in. hg vacuum levels with a single stage, and operate against pressures up to 35 psig.

Convert your direct-acting solenoid valve to pneumatics
The PneuMagnetic actuator is a drop-in replacement for the OEM coil on an industrial direct-acting solenoid valve. This self-contained pneumatic-magnetic device provides the same powerful on/off magnetic field as the original coil. Valves converted to PneuMagnetic are operated by an inexpensive air pilot using a small-diameter, flexible pneumatic line. No electricity. No field wiring. No conduit. And no intrinsically safe IS barriers required.

Retain load on hydraulic power or pump failure
The AMLOK Hydraulic Series RCH Rod Clamp has been developed to provide power-off clamping of rods and shafts. The type RCH Rod Clamps are actuated by a spring/collet mechanism and unclamped by hydraulic pressure. These rod clamps are designed to clamp components after the motion has stopped and to hold the position securely as long as the forces do not exceed the table values. For braking and pneumatic applications, contact the factory.

Economical electric actuators
The EPZ Series of Industrial Electric Actuators is an economical solution for small-diameter ball valves and well suited for tight-space applications. The actuators are available in two sizes: the EPZ-6 and EPZ-15. The EPZ-6 has a torque output of 55 in.-lb/ 6 Nm, and the EPZ-15 features an output of 135 in.-lb/15 Nm. Both sizes are non-spring return with NEMA 4/4X enclosure, and have an ISO5211 F03/F05 mounting pattern. Other key features include: on/off jog control capabilities, aluminum alloy dry powder-coated housing, thermal-class F motor protection, and manual override including lock-out functionality. Typical applications or installations include but not limited to waste and water treatment, chemical processing, food and beverage, pharmaceutical, pulp and paper, irrigation/agriculture, marine or corrosive environments, aquatics, and water/theme parks.

More than 1,000 hydraulic macros
A new, comprehensive master data package for hydraulics now bridges the gap between fluid and mechanical design. More than 1,000 new hydraulic macros in Eplan Fluid software speed up and simplify interdisciplinary documentation. The advantages of a common set of control technology documentation for fluid and electrical engineering are well known; a look at hydraulics opens up even more potential. From the beginning, Eplan Fluid 2.0 offered users a comprehensive "fluid data package" containing more than 1,000 hydraulic macros. The combination of CAE functionality and the new macros provides unbeatable advantages for hydraulic designers, especially in mechanical engineering.

Pneumatic actuator approaches zero friction
Airpel Plus is a line of high-performance, low-friction air cylinder actuators. The benefit engineers derive from these low-friction levels is an enhanced ability to control ultra-precise movements, including high speeds and extremely short travel distances with clean, long-life pneumatic devices. The inert qualities and tight tolerances of the glass and graphite materials used in these actuators allow engineers to develop systems that will move, hold, or press accurately and with amazing repeatability.

Ultra-low pressure sensors
The LPSI/LPS2 Series offered by Servoflo Corporation consists of ultra-low differential pressure sensors measuring from 0.1 in. to 5 in. of water in various non-directional or bi-directional calibration ranges. Based on a MEMS thermo-anemometer, the LPSI/LPS2 Series infers differential pressure from a nano-liters per second gas flow through an integrated airflow channel. The on-chip circuitry provides analog amplification and temperature compensation to send an accurate linear output over a wide temperature range (±2.5% FS from 5°C to 55°C). The LSP1 comes in various ranges from 0.1 in. to 2 in. of water, while the LPS2 is available from ranges between 1 in. to 5 in. of water. Standard input voltage is 5 VDC, and a 3V model is also available.

International celebration aims to recognize pumps as ‘heart of industry'
ITT Goulds Pumps recently announced a worldwide effort to celebrate pumps as the "heart of industry." Mark your calendars.
Various festivities and observations – including efforts to support heart health and recognize people who keep pumps running – will culminate on Pump Appreciation Day, April 10, 2012.
"Most people are unaware of the impact pumps have on everyday life, but industrial pumps are the unsung heroes of manufacturing. Without them, factories can't function," says Robert J. Pagano Jr., president of the ITT Industrial Process business, which includes ITT Goulds Pumps. "Pumps are really the heart of industry, essential to making basic materials like paper, plastic, and steel, and to powering our life with gas and electric. Pump Appreciation Day will support a good cause, while educating the public about the importance of pumps and recognizing the people who design, install, operate, and maintain them."
Pagano says that the company will soon announce new details to encourage participation in the day. Current plans include:
- Customer and employee-recognition events by ITT Goulds Pumps, its distributors, and customers.
- Donations for the international Emergency Cardiovascular Care (ECC) Program, which is supported by the American Heart Association and its global partners. ITT Goulds Pumps will donate money and hold events for the program, which teaches first aid, including the recommended method for hands-only CPR. The company already has launched the World of Pumps Quiz (www.worldofpumpsquiz.com), which challenges its customers to answer industry-related questions and pledges donations to the ECC Program for every correct answer. Between now and April 10, additional efforts will contribute to this initiative for fundraising and awareness.
- Timelines, fact sheets, and educational materials highlighting the role of pumps in modern life and in specific industries.
"Without a heart, life stops, and without an industrial pump, manufacturing stops," Pagano says. "ITT Goulds Pumps is launching this global effort to promote healthy operation in both areas."
