• Flows: to 1,500 GPM (341 m³/h)
• Heads: to 120 feet (37 m)
• Solids: to ¼ inch (6 mm)
• Pressures: to 75 psi (517 kPa)
• Available Lengths: 4-foot (1.2 m) and 6 ft (1.8 m)

Mechanical / hydraulic

Design Features

• Maximum interchangeability: Wet ends are completely interchangeable with horizontal Model SRL to ease maintenance and reduce inventory.
• Large-diameter impellers: Develop higher heads at lower RPMs for improved wear; open design ideal for sump service; available in a variety of elastomers.
• Field-replaceable elastomer liners.
• Designed for lower operating costs.
• Heavy-duty bearing frame for reliable performance.
• Large-diameter shaft for low deflection.
• Operation below first critical speed.

Standard Features

• Motor mount and V-belt guard provided as standard.
