Precision Actuator Puts New Spin on Solar Power
structural element between the solar panels and support pylons. Positive-displacement gear pumps built by Parker's Oildyne Div. in Rockford, Ill., supply highpressure fluid to the actuators. A low-speed, 1.5-gpm pump, driven by a1/3-hp, single-phase electric motor, powers the actuator as it positions

Straight Talk on Wobble-Piston Pumps
or as high as 212°F. The quality of air surrounding the pump, whether clean, dusty, humid, dry, or containing volatile gases, determines filtration and sealing requirements. Media. Chemicals and moisture in the air, as well as media temperature, affect pump sizing and construction. For example, piston-cup

Hannover Fair Focuses on Energy Efficiency
., will take the wraps off a smart variable-speed pump drive that matches flow to demand, cutting motor/pump speed when hydraulic systems don't operate at full load. This reportedly cuts energy consumption up to 45%, as well as reduces noise and hydraulic fluid temperature. 's EC fans are said to use

Iron Fouling Problem Solved with Mobile Pretreatment
This client operates a groundwater treatment facility at a Super Fund site where groundwater is pumped to a VOC stripper for the removal of TCE which is then re-injected into the aquifer.A High iron levels in the groundwater caused fouling of pumps, pipes and well casings.A This fouling threatened
