OHHL low flow high head pumps

Finely tuned pumps for all your industrial needs
The OHHL is our API 610 (ISO 13709) Type OH2 low-flow horizontal overhung process pump. It covers the low-flow end of the OHH range map. The unique low-flow impeller design provides gap-free coverage for low-flow, high-head applications. The bearing frame and mechanical seals from OHH are utilized to minimize spares inventory.

Ultra-Low Head Submersible Water Pumps

​Flygt’s submersible axial flow pumps are suitable for high flows and very low head applications in clean water and wastewater. Reliable, rugged and proven for more than 30 years, these pumps install horizontally for ease of handling and maximum pump system efficiency. Wall mount or discharge pipe mounting is available.​

Flygt ultra-low-head propeller pumps are state-of-the-art high-capacity ultra-low-head pumps for clean and lightly contaminated water. These submersible pumps are horizontally installed and operate directly in the pumped liquid, they are very easy to install and remove. The product offering makes them the ideal choice for a number of very-low-head applications. The pump’s compact size and the resulting compact station make for a very-cost efficient pump solution. The typical pump is installed directly on a vertical concrete wall with the discharge line going through the wall for the lowest installed cost.

High flow with Low head pump

QSH, QSZ axial flow, and mixed flow pumps; these are what you want. These pumps are perfect for throwing water over a levee wall (the kind that Louisiana would never pay for and could have prevented Katrina flooding…but thats another story).

Axial flows typically between 5-40 ft of head, mixed flow between 30- 80′ or thereabouts. As said above, they are typically vertical pumps; axials (sometimes called propeller pumps)are named such because axial forces are dominant in moving the fluid axially along the shaft. Their energy is used to create flow, not head. Specific speeds usually range from….maybe 10K-25K….

1500 gpm is really not a huge volume; some of these monsters can easily move 100,000 gpm. Go check out Goulds, Floway, Flowserve, Patterson, Sulzer (they now own the old Johnston pump line). A cheaper version was made by a company called Low-Lift. They were totally fabbed pumps, no castings, and had huge installation base.
