Today’s pumps, valves, and flow meters are being designed with greater accuracy and flexibility to handle a wide range of fluids, chemicals, and other materials. Demands for more reliable operation and lower energy usage dictate these parts be made of materials lighter than previously available, yet robust enough for high pressure, high duty cycle applications.
The performance and reliability of pumps and valves has gotten better, thanks to improvements in sealing materials and fittings, noted Dr. Joseph Kovach, Vice President of Innovation and Technology for Parker Hannifin’s Hydraulics Group. “Systems have become leak-free. We‘ve done interesting things with material and face sealing technologies.
Bent-axis designs are reducing the amount of friction in pumps and allowing higher operating speeds, Kovach noted. He added that some innovative pump designs now incorporate valves to regulate flow and reduce energy usage.
The valves have independently adjustable, spring-loaded seats for long life. Standard port sizes are 3/16, ¼, 3/8, or ½ in. Standard connections are male or female NPT, M/P cone and thread, and H/P cone and thread. Fiveway valve configurations optimize process control, with an optional three-way valve for switching or diverting operation. Construction materials include type 316 stainless steel, glass-filled Teflon packing, and glass-filled PEEK seats and Viton seals.
The pump is available in models rated 12 and 24 Vdc. It is made of Santo-EPDM and Santo-Viton to resist corrosion.
The flow monitor covers five flow ranges up to 100 gpm at up to 6000 psi. Custom and OEM versions are available. Applications include condition monitoring, preventive maintenance, component testing, and closed-loop control.
