Old and New

There’s a natural tendency at the onset of a new year to think about all sorts of things shiny and new, including possibilities that may lie ahead. Yet we shouldn’t lose sight of, nor appreciation for, what’s been long established. It’s the same in our field, as for every brand new process system we might have the opportunity to put together, there are scores of the maintenance, replacement, and improvement solutions and equipment to existing systems, that are just as important and rewarding. At the Charles P. Crowley Company, we’re here for you, whether the challenges you face are old or new.

We’re kicking off the new year with a look inside field equipment protection and shelters that are built to last. Next, it is all about making what’s old, new again with the help of a one-stop shop for all your rebuild needs. Things wind up by highlighting three key advantages when it comes to rotary positive displacement 3-screw pumps.

Top Three

Manufactured under ISO 9001 Quality Management Systems, IMO PUMP, a CIRCOR business unit, continues to be on top when it comes to rotary positive displacment 3-screw pumps.

The largest class of multiple screw pumps in service today, IMO’s 3-screw pumps are the preferred choice for machinery lubrication and powering hydraulic machinery, among many other applications. Flow rates are available from 1 to 3300 GPM (4 to 13,250 L/M) or for operating pressures to 4500 PSIG (310 BAR). IMO designs include seal-less configurations, such as magnetic drives and canned arrangements.

IMO 3-screw pumps incorporate a positive displacement rotary design consisting of a housing which envelops the drive screw (power rotor) and the sealing screws (idler rotors). Renowned for their low noise levels, high reliability, and long life, IMO 3-screw pumps are also capable of water injection services, as well as coolant service for machine tools. 

Strengths of 3-Screw Pump Technology

  • High pressure boost capabilities, even when handling low viscosity fluids
  • One of the highest overall efficiencies when handling heavy crude 3
  • Simple pump design with only three rotating parts and one shaft seal
