REGIONS SUPPLY BUYING GUIDE

Product details & buying advice

Choose a transfer pump by its intended operating duty, then confirm how the pump, drive and bypass arrangement will work together.

Product type LP gas transfer pumps
Part / SKU Z3500

What to check before ordering

  • Use the exact model’s performance curve to compare required flow, liquid service and differential pressure.
  • Check the suction conditions, motor or drive selection and external bypass requirements.
  • Use that model’s operation and maintenance manual for installation alignment, startup and service.

Service reminder: Review the bypass instructions even if the pump has an internal relief function. The internal function does not automatically take the place of the required external bypass.

Have gas-system installation and service completed by qualified personnel. Use the current instructions for the exact model and the requirements that apply at the installation location.

Complete Description

CORKEN Z3500 3″ CORO-VANE POSITIVE DISPLACEMENT SLIDING VANE PUMP – Z3500HGA6MT – PUMP ONLY

Offered is a Corken Z3500 3-inch Coro-Vane positive-displacement sliding vane pump, configuration Z3500HGA6MT. This listing is for the pump only/bare pump; motor, base, belt drive and other accessories are not included unless specifically shown or stated in the listing.

The Z3500 is a heavy-duty, high-capacity pump designed primarily for transferring LPG, propane, butane and agricultural ammonia (NH3). Its positive-displacement sliding-vane design provides excellent suction performance and consistent product transfer.

The Z-Series incorporates a six-vane design with vane drivers, an improved cam design and a high-capacity needle-roller thrust bearing. The self-adjusting sliding vanes help maintain pumping efficiency as normal wear occurs.

Maintenance is simplified because removing the pump head provides access to major internal components including the bearings, seals, sideplates, rotor, vanes and vane drivers. The reversible sideplates and replaceable wear components further support long-term serviceability.

The Z3500 provides approximately 52–197 GPM flow capacity and is rated for a maximum working pressure of approximately 350 PSIG, making it suitable for demanding bulk-transfer and plant applications.

Please verify the exact model/configuration, rotation, seal materials, operating pressure, fluid compatibility and connection requirements before purchase.
