1. Multi Stage Horizontal & Vertical Pumps
Horizontal & Vertical multistage centrifugal pumps come with various sizes and various numbers of
stages to provide the flow and the pressure for various applications. Multistage pump is suitable for a
wide variety of applications from pumping of potable water to the pumping of chemicals. SAERTM –
TMB – TMV series -range offers high efficiency, high resistance to sand and other abrasives and allows
solid contents, motor burnout protection, and easy maintenance.
