Corken® "Z" Series NH3/ LPG Pump

4" x 3" Flanged, 382 GPM @ 780 RPM

The Z4500 is a 4 in. stationary LPG pump designed for transport loading and multiple bobtail loading applications. If you have two or more bulkheads to load bobtails and transports and would like to shorten your fill times, then the Z4500 is the stationary pump for you.

  • Large diameter non-metallic pins are not speed sensitive so you can operate the pump at a higher RPM and not damage the pump.
  • High tech materials used on cam and blades help extend the life of the pump.
  • Unlike other four-inch stationary pumps rated at 640 RPM, the Z4500 is rated up to 800 RPM providing higher capacity without damage.
  • Maintenance made simple. When it becomes necessary to service the Z4500 stationary pump, all you need to do is remove eight head bolts to inspect the bearings, seals, sideplates, rotor, vanes and vane drivers.
  • Higher capacities than other four-inch stationary pumps—up to 15% more at typical operating conditions.
