  • Fluid Handling Achieve optimum centrifugal pump performance Food Processing
    Centrifugal process pumps often must perform in hostile and stressful operating conditions. As a result, the likelihood of their premature failure increases over time raising risks of incurring considerable costs and lost productivity from downtime. With pressures mounting to achieve better pump
  • Applying Inverters to Centrifugal Compressors in HVAC Chillers (.pdf)
    When applying an inverter to centrifugal compressors on HVAC chillers, there are a number of factors to consider. For some compressors, lubricating oil circulation may be driven by the rotation of the compressor shaft itself, via a gear-driven pump arrangement. If you slow the motor speed
  • CRV Flex and Pump Applications (.pdf)
    Since all centrifugal pumps require well-developed inlet flow to meet their potential, a pump may not perform or be as reliable as expected due to a faulty suction piping layout such as a close-coupled elbow on the inlet flange. When poorly developed flow enters the pump impeller, it strikes
  • Pump Solutions for Abrasive Mining Applications
    in mining operations challenge conventional pumps. High solids content and the corrosive nature of chemicals (Figure 4) like cyanide, methylcellulose, sodium diothiophosphate, copper sulfate and SIBX (Sodium isotol butyl xanthate) create problems for diaphragm, centrifugal or other types of pumps where
  • Vacuum and Pressure Handbook: Vacuum Pumps
    and low flow. rates. The principle types of nonpositive displacement vacuum pumps are the centrifugal,. axial-flow, and regenerative designs. Single-stage regenerative blowers can provide vacu-. ums up to 7 in. Hg with flows to several hundred cfm. Vacuum capabilities of the other. designs are lower
  • Self-Priming Horizontal Pump for Chemical Plant
    and head at various speeds of rotation: in this way, it was easier to evaluate the volume of liquid transferred simply using a chronometer and a pressure gauge. Centrifugal pump for a chlorination system. The initial problem. Heavy wear on a series of pumps installed in a pool chlorination system
  • Fluid Handling Keep parallel pumps in line Chemical Processing
    hydrotreater (hydrogenation) unit, two identical eight-stage centrifugal pumps originally were installed: one for normal operation and the other as a spare. By operating both pumps, itÂ’s possible to increase the available head because each pump has a lower flow rate. As the pump curve (Figure 1) shows
  • Peristaltic Pumps Provide Option for Ethanol Producers
    and understand the differences in the various types of pumps. An Overview of Positive Displacement Pumps. Unlike constant-speed, solids-handling centrifugal pumps, which are predominantly used in transferring fluids, positive displacement (PD) pumps were created to meter or transfer hard-to-handle fluids
