WARRENDER Brand Name & Website Links

All WARRENDER, LTD. mag-drive pumps are now trademarked simply as WARRENDER for the heavy-duty process pumps and PROMAG for the Series M; we strongly advise discontinuing any reference to the CASTER trade name in your proposals or linking to the CASTER website. Additionally, an updated and expanded WARRENDER, LTD. website is nearly complete and we urge all qualified distributors to link websites to www.warrender.com.

Series WMCA/WMDA Heavy Duty Alloy Centrifugal Process Mag-Drives The ISO-2858 pump design was selected by the pump industry as the new world specification for centrifugal process pumps. The ISO commit-tee, who included U.S. pump manufacturers, chose DIN over ANSI for clear reasons. In effect, the ISO-2858 pump spec evolved from the Ger-man DIN program and is essentially a DIN pump equipped with ANSI flanges. The technical advantages of DIN over ANSI are extensive and include the following:

1. Closely governed flow and head capacities (within a few points) for direct interchangeability between manufacturers 2. Complete hydraulic coverage for optimal efficiencies. For example, 5”, 6”, 8” & 10” nominal impeller/casing sizes are

available in all 2x1.5, 3x1.5, 3x2, and 4x3 models. Larger models include a 6x3x6 & 6x4x8, plus 8”, 10” & 13” sizes. 3. Improved hydraulic stability with lower velocities respecting the “5 / 7 Velocity Rule” (i.e., velocities of 5 feet per second

for suction & 7 feet per second for discharge) 4. Lower NSSS (Net Suction Specific Speed) values that match engineering guidelines for oil refineries and engineering

companies 5. Fully enclosed impellers for reduced axial thrust loads, and proper running clearances, even under extreme temperature

conditions- hot or cold 6. Heavier duty pump foot for higher nozzle loading ratings that meet API requirements 7. Longer pump frame design for increased bearing spans to meet L10 (3 year) bearing life requirements 8. Pump casings equipped with wear rings for maintaining pump performance and efficiencies without troublesome

interference or hydraulic slippage

WARRENDER Alloy Series WMCA Compact Centrifugals

The Series WMCA Compact range is a sub-ANSI centrifugal process pump with numerous design enhancements over the original “SR” units. The improved features include high torque neodymium or samarium cobalt magnetic couplings suitable for high temp or cryogenic services. Stainless steel shafts are fitted with silicon carbide shaft sleeves and carbon journal bearings for intermittent dry-run capability (silicon carbide optional). The confined casing gaskets circumvent o-ring degradation or the expense of Kalrez™. An external bearing flush port is equipped on all WMCA Compact pumps for solids handling.

WARRENDER Alloy Series WMTA Regenerative Turbine

The Series “WMTA” is the latest regenerative turbine design with numerous enhancements over the original “MTA” units. New features pattern those of the “WMCA Compact”, excluding the external flushing. Additional improvements include cast alloy pump casings (NPT or flanged) with a 90 degree suction port. The impeller screws have been eliminated. NOTE: WMTA/WMDAT alloy turbine process pumps can be built to API-610 8th Edition or API-685 specifications for low flow / high head requirements.

WMTA Cast Single Stage Pump

WARRENDER Alloy Series WMCA ISO-2858 For the stated reasons, ISO-2858 pumps offer a rugged alternative to ANSI pumps without compromising interchangeability. Also, ISO-2858 pumps meet API requirements and are suitable for temperatures below 350 degrees F (in accordance with the API-610-8th Edition specifications). For temperatures between 350 to 600 degrees F centerline mounted pumps are available to ensure uniform casing growth without misalignment issues. The ISO-2858 pump design is an ideal platform for mag-drive configurations. The API-685 Seal-less Pump specification mandates centerline mounting but was intended for extreme high pressure services rated for 750 PSIG MAWP, and also severely hazardous process systems with very dangerous or explosive liquids (e.g., hydrofluoric acid, LPG, LNG, etc.).
