  • Blackmer C-Series Mouvex Principle Eccentric Disc Sealless Pump Technology
    , the global demand for highly reliable pumps that can eliminate leaks, provide gentle handling of liquids and provide high volumetric efficiencies and economic advantages has substantially increased. Eccentric disc technology pumps are uniquely qualified to meet all of these demands. (Figure 1). Key Design
  • Medical Device Link . Comparing Liquid and High Consistency Silicone Rubber Elastomers: Which Is Right for You?
    , replacement finger joints, and pump diaphragms. Low viscosity makes liquid silicone rubbers suitable for molding applications requiring complex, intricate molds. Photos: Dow Corning Corp. These elastomers are commercially available in two types: millable high consistency silicone rubber and pumpable liquid
  • Fluid Performance Factors
    most important property of a hydraulic fluid. A hydraulic fluid that is too viscous usually causes high-pressure drop, sluggish operation, low-mechanical efficiency, and high-power consumption. High-pressure, high-precision systems are particularly sensitive to viscosity at low temperatures. They can
  • Hydraulic fluids change with the times
    through a bearing -- and with it bearing friction and load-carrying capacity. Fluid with the proper viscosity quickly distributes to moving surfaces -- a key to long pump life. Fluid with lower-than-recommended viscosity can cause internal pump leakage and raise
  • Know your thrust bearings
    pump to provide oil-film pressure when simple, internal hydrodynamic pumping action cannot generate sufficient force. Primary use is in equipment run at extremely low speeds, under high loads, with low viscosity fluids, or where space is limited. A compact thrust bearing can feed high-pressure oil
  • Evaluating the performance of dual PTFE filter assemblies in hot-acid etch baths
    of wafers is extremely important. The studies reported in this article examined the removal efficiency and temperature and viscosity independence of recently developed filter assemblies suitable for use in recirculating phosphoric and sulfuric acids. High-temperature (150 180 C) phosphoric acid
  • A fan of fuel savings
    connects to a valve that directs fluid to a fan clutch. High temperatures engage the clutch and low ones disengage it -- well, almost. Engaged viscous-coupled fans typically slip about 5 to 10% of shaft speed. And disengaged fans may still run at about 45% of engaged speed, especially at low engine rpm
  • Medical Device Link .
    timers to control a high-duty-rate solenoid valve. The dispensing cycle time, between 0.01 and 31 seconds, is operator adjustable. A configurable barrel suck-back feature prevents low-viscosity fluids from dripping. Each dispenser comes equipped with hardware, fittings, hoses, a foot switch, a barrel
