Axially split volute casing pump

Product catalog summary

Overview: The RDLO axially split volute casing pump is designed for various applications including water works, irrigation, power stations, industrial water supply, petrochemical industry, marine engineering, and seawater desalination. It is suitable for pumping pure, raw, industrial, and seawater.

Key Features:

High Operating Reliability: Equipped with a double volute and double-entry impeller to minimize radial and axial forces, ensuring a theoretical operating life of at least 100,000 hours.
Low Maintenance Costs: Features solid bearing brackets, a rigid shaft, and corrosion-resistant materials, leading to low vibrations and extended service life of components.
Service-Friendly Design: The self-centering upper casing and spring-loaded rotor allow for easy assembly and maintenance, with accessible internal components.
Optimal Tightness: The solid casing split flange ensures reliable sealing between the upper and lower casing halves.

1387.021/3-10 / 10/08 / Subject to technical modifications. / © KSB Aktiengesellschaft 2008 RDLO – Axially split volute casing pump 1 High operating reliability Since the casing is equipped with a double volute (compensating the radial forces) and a double-entry impeller (compensating the axial forces) the bearings only experience a minimum load. The theoretical operating life L10 for all sizes is at least 100,000 hours. 2 Low maintenance costs The combination of solid bearing brackets, which are bolted to the upper casing part, the rigid shaft and the casing with double volute, guarantees low...
