Mark 3 Lo-Flo Overhung Chemical Process Pump
Mark 3 Lo-Flo Overhung Chemical Process Pump
| Brand: | Durco |
|---|---|
| Description: |
The Durco Mark 3 Lo-Flo pump is designed to improve pump reliability and performance in low-flow, high-head applications. As part of the Durco Mark 3 ANSI pump family, it features a robust overhung design optimized for precise chemical dosing, sampling, and transfer where traditional pumps are oversized or inefficient. Engineered by Flowserve, the Mark 3 Lo-Flo delivers stable operation, reduced vibration, and extended seal and bearing life, even at low capacity. This makes it the ideal solution for chemical processing, pharmaceuticals, petrochemicals and other industries requiring accurate and reliable fluid handling at reduced flow rates. Compliant with ASME (ANSI) B73.1 standards, the Mark 3 Lo-Flo ensures dimensional interchangeability and is built with corrosion-resistant materials for handling aggressive, toxic or temperature-sensitive fluids. |

Radial Vane Impeller provides improved performance over a broader application range.
Circular Concentric Casing reduces radial loads and vibration and extends bearing and seal life.
SealSentry Seal Chambers extend seal life and provide advanced self-flushing ability.
External Micrometer Impeller Adjustment accurately sets impeller clearance in 20 seconds, in the shop or the field.
Metal-to-Metal Construction assures a true running and concentric shaft, extending bearing and mechanical seal life.
Large Shaft and Bearing Components extend bearing life and reduce shaft deflection and vibration.
