The innovative, hydraulically-driven Hydraflo™ axial and mixed flow pumps were a critical asset in dewatering New Orleans after Hurricane Katrina. Moving Water Industries sent 20 large portable pumps which were used for months in multiple locations until the city was dry. And they are an important part of future storm or hurricane drainage projects – both temporary and permanent. The Army Corps of Engineers acquired 40 of our 60 inch pumps and their drive units with 720 HP Cat Diesels.

Why Choose the MWI HydraFlo™?

Versatility

The Hydraflo™ pumps can be installed at any angle - vertical, horizontal or any angle in between, by simply changing the intake bell. They can pump in both directions for a two-way operation. For higher head applications, two or more Hydraflo™ pumps can be staged together by bolting one on top of the other. In addition, one prime mover might also be used to drive several different pumps which provide even more versatility and convenience.

Fast Installation

The Hydraflo™ pumps can be installed within a fraction of the time of conventional lineshaft pumps or submersible electric pumps. A typical installation can be done in hours, because they do not require any critical alignment or the extensive civil works required by other high capacity pumps. Hydraflo™ pumps are very portable and especially well suited for installation in severe settings.

Designed for Longer Life

The Hydraflo™ pumps are designed for a very long life. All components are picked for ruggedness and durability. Many Hydraflo™ pumps over 25 years old are still in daily use. Propeller blades are manufactured from ASTM A304 corrosion and abrasion-resistant stainless steel. A stainless steel wear liner is standard.

Less Submergence Required

Because the standard design of MWI Hydraflo™ pumps include large intake passages and low speeds, they can be installed and operated continuously at minimal submergence allowing savings in pump costs.

Requires Less Maintenance and Costs Less to Operate

The Hydraflo™ is a simple, straightforward design that requires very little maintenance. When used in the portable mode, they pump more water for less money and have a smaller footprint than the many centrifugal pumps that would be required to take its place. The hydraulic motor and bearings are sealed to operate maintenance free under water. There are no priming problems and no need to worry about the pump running dry. Hydraflo™ pumps are designed to run dry without damage to their components. There are no belts to align, tighten or replace and no open shafts with the Hydraflo™ pumps.

Variable Speed Pumping

Pump speed can be varied manually by regulating engine speed. An automatic variable speed option is also available. These features make the Hydraflo™ ideal for varying flow or head conditions. Level sensing can be keyed to automatically match pump capacity and speed to incoming system flows.

Environmentally Friendly

We offer several hydraulic fluid options which are readily biodegradable and meet the EPA toxicity limits. Hydraflo™ hydraulic tanks are small and have an engine shut down switch activated by small amounts of fluid loss. Hydraflo™ pump stations are also less likely to disturb the environment because the pumps require minimal civil works, have a very small footprint and a low profile.
