Multi-Stage Ring Section Pumps

Overview

Centrifugal, single-casing radially split between bearing pumps is designed in a modular way based on different ranges of pressures for use in a wide range of applications, primarily for pumping clean or slightly polluted liquids. These pumps are also known as side channel pumps, or liquid ring pumps.

Features & Benefits

• Mid- to high-pressure.
• Modular hydraulics for high efficiency in a wide range of operating conditions.
• Fast and easy impeller mounting.
• Simple construction to minimize dimensions and reduce investment and maintenance costs.
• Centerline mounted with large branch sizes for optimized inlet flow, low noise level and higher allowable forces and moments.
• High-quality investment cast impellers and diffusers for improved efficiency.
• Double suction first-stage impeller available for selected pump sizes.
• Vertical design available.
• Long and trusted experience in all industrial segments.
• Single or double packing or mechanical seal.
• Clock-wise rotation (viewed from coupling end).
• Available in base-mounted and drive-coupled configurations.
