Mechanical / Hydraulic

Design Features

• Extra-Thick Wet End Components for extended wear life.
• Replaceable Wear Liner for low maintenance cost.
• Heavy-Duty Power End for increased mean time between failures.
• External Impeller Adjustment to maintain original efficiency; simple and fast.
• Maximum Parts Interchangeability across the entire line, using just five power ends.
• Sealing Flexibility with a choice of packing, mechanical seals, or Dynamic Seal.

Pump Components

Key pump end components include:

• Casing (extra-thick wall sections, dual-volute design where necessary)
• Impeller (slurry design, back pump-out vanes)
• Suction Cover Liner (replaceable)
• Suction Cover
• Stuffing Box Cover

Power End Components

Key power end components include:

• Heavy-Duty Bearing Frame (rugged one-piece design with integral drip basin, grease or oil lube)
• Rugged Shaft Assembly (designed for continuous service, minimum deflection)
• Replaceable Shaft Sleeve (hook-type design protects shaft)
• Radial and Thrust Bearings (sized for 3-year life / 25,000 hours)

Sealing Options

• Dynamic Seal: An expeller pumps liquid from the stuffing box, often eliminating the need for external flush water, reducing leakage and contamination.
• Mechanical Seal: Goulds offers a variety of mechanical seals, including special slurry seals. An enlarged TaperBore™ seal chamber is available for improved lubrication and cooling, with a tapered throat to keep solids away from seal faces.
• Packing: Available with a lantern ring and graphitized polymer fiber packing.

Drive Arrangements

The Model JC can be supplied with various drive arrangements for application flexibility, including:

• Direct Drive Unit
• Overhead Belt Drive
• Side-by-side belt drive
