Magflow® TOW Split Case Pump Product Description
Magflow® TO and TOW(II) series pumps are heavy-duty, single-stage, double-suction, axially split volute centrifugal pumps engineered for high-efficiency fluid transfer and reliable long-term operation. Featuring an axially split casing design, the upper and lower halves can be separated for easy inspection and maintenance of the rotor assembly without disturbing the suction and discharge pipe connections or the motor driver.

Magflow® TOW Split Case Pump Design Features
Double-Suction Impeller: The dual-inlet hydraulic design balances axial thrust, minimizes bearing loads, and ensures stable operation even at high flow rates and low net positive suction head (NPSH) conditions.
Axially Split Casing: Simplifies routine maintenance and overhauls, allowing direct access to internal components (impeller, wear rings, and shaft) without dismantling the pipeline infrastructure.
High Hydraulic Efficiency: Optimized volute and impeller geometry reduce turbulence and energy losses, delivering superior efficiency across a wide operating range.
Flexible Configuration: Available with various mechanical seal or packing seal arrangements, alongside flexible flange standards and customizable rotation directions to suit specific plant layouts.
