EBARA MS/MSL/MSH – Horizontal Multistage Pump
The EBARA MS, MSL, and MSH series are horizontal multistage pumps designed for high-pressure applications. These pumps offer high efficiency and robust construction for a wide range of industrial needs.
Key Features:
EBARA’s unique double volute construction provides higher operational efficiency across a broader capacity range compared to conventional guide vane pumps.
The simple pump structure contributes to a longer service life. These pumps are compact, lightweight, and operate with minimal noise.
The double volute casing is designed to balance radial forces across the full operating range. Axial force is absorbed by a balance disk equipped with a wear indicator at the shaft end.
All components are fully standardized for easier service and maintenance.
The pump is designed not to exceed rated horsepower at any capacity. (MS model)
