  • Reduces inventory requirements.

ECCV Series provides a vertical cantilever (tank type mounting) option that covers all 21 available pump sizes. Each vertical cantilever pump is tailor made to suit customer requirements.

Greater Wear Life

  • Supplied in high-grade grey or ductile iron, carbon steel, and stainless steel alloys, and/or in combination of same.
  • 316SS, 317SS, & Duplex Stainless Steel commonly employed.
  • Designed for maximum wear life, minimum downtime, and reduced life time costs.
  • Supplied with alternative materials of construction and/or tailored to suit specific process liquors upon request.
  • Pump fasteners in 304SS or 316SS unless otherwise specified.

Ease of Maintenance

  • Simplified and faster maintenance facilitated by employing spacer type couplings for “back pullout” on all horizontal models.
  • By employing a back pullout design, the entire pump range has an in-built ability to remove the complete bearing frame/rotating assembly without disturbing the pump casing, suction and/or discharge pipework, or the electric motor/diesel engine driver.

Fixed / Variable Speed

  • Impellers can be cut to size to suit a specific fixed speed duty or can be left full size diameter when pump is coupled to a variable speed drive.

High Performance

  • Volutes and impellers designed to handle and withstand erosive and/or corrosive liquors with low wear rates, high efficiencies, low suction pressure (NPSH), and lower power costs.
  • Horizontal pumps effect and maintain the impeller to Casing clearance and high efficiency, by using accurate rigid shim sets.
  • Vertical pumps effect same using a top side shaft coupling adjustment mechanism.
  • Ability to adjust impeller clearance (to counter natural wear) without removing the pump and/or the rotating element reduces downtime and downtime costs, and maintains optimum pump performance.

Semi Open Impeller

  • Semi-open impellers fitted with flow inducing vane contours and balance/relief holes.
  • Designed to withstand erosion/corrosion, prevent high thrust loads, and reduce stuffing box pressures.
