SX50/SX50H

APPLICATIONS

Myers

®

 SX50 series pumps are 

versatile performers designed  
for commercial, municipal and 
industrial applications. The SX50 
(high flow) and the SX50H (high 
pressure) are designed to pump 
contaminated water containing  
a wide range of pollutants. Each 
pump is matched with a safety-
proven Myers
