Self-Priming Pumps - Gorman-Rupp Pumps

WHAT IS A SELF-PRIMING PUMP?

A self-priming pump can be installed high and dry above the fluid level while automatically removing air from the suction line and filling it with liquid without manual priming. These pumps are designed to prime themselves quickly and efficiently and can continue operating even if the liquid supply is interrupted.

Today, Gorman-Rupp self-priming pumps are the world’s leading choice for waste handling applications in industries such as steel and paper mills, mining operations, food processing plants, power plants, automotive factories, tanneries, and wineries. They are also the pump of choice in many sewage-handling applications worldwide.

Gorman-Rupp self-priming centrifugal pumps are easy to install and easy to service. Because they’re self-priming, they can be mounted high and dry at floor level with only the suction line in the liquid – there’s never a need for service personnel to enter the sump. When service or maintenance is required, it can be completed effortlessly with standard hand tools. No long drive shafts to install and align and no hoists or cranes are required.

Appalachian Self-Priming Surface Pumps

The DAE Pumps Appalachian Self-Priming Surface Pumps are the industry’s most versatile self-priming surface pumps. These heavy-duty pumps extend a range of industries from applications like dewatering mines and construction sites, removing floodwater, and a variety of other municipal applications. The Appalachian pump provides the non-clogging performance, reliability, and ease of use you need.

The Appalachian surface pumps comprise of an air separator unit and a vacuum pump, offering rapid automatic priming. Even with suction heights of several feet, these tools rapidly evacuates the air from the suction pipe and starts to pump. In addition, the semi-open impeller is suitable for pumping liquids with solids in suspensions.

Appalachian pumps are available in a range of sizes and power. Options include towable tailor mounts or skids, and open frame or sound attenuated. Choose from multiple rugged surface pump designs, including high head models.

Dewatering Surface Pumps Applications

At DAE Pumps, we have a surface pump for every dewatering application. For every industry and for every use, we have you covered with high performance, reliable, and easy to use self-priming surface pumps.

Oil & Gas

Pipelines used to transport crude oil or natural gas must be dewatered to guarantee the quality of the hydrocarbons and prevent the formation of hydrates and protect pipes from internal corrosion. The ballasting process requires robust high performing pumps which, based on the needs, pumps seawater in and out of the shipyard tank during the loading and unloading of water vessels.

Applications

Ballasting
Pipeline hydrostatic test
Drilling
Pipeline flushing

Mines and Quarries

For dewatering applications in the mines post dredging, our pumps offer effective and efficient solutions due to their solids handling capability.

Applications

Dewatering
Water relaunching
Washplants
Silt and sludge removal

Municipalities

Municipal public service applications can vary from sewage bypass to wastewater treatment plants to water reclamation centers. When wastewater is being treated, our pumps handle the fluids and solids without clogging or failing.

Applications

Sewage bypass
Dewatering
Emergency water treatment

Construction

Applications

Ballasting
Pipeline hydrostatic test
Drilling
Pipeline flushing

Industry

The effluent produced by different industries should be treated, relaunched, or drained. With the availability of different materials for our wet ends, we offer a complete solution.

Applications

Effluent handling and transporting
Waste drainage and disposals
Temporary firefighting protection

Civil Works

Modern-day civil engineering projects are fast-paced. Be it the construction of roads, dams, bridges, airports, or buildings, site dewatering, and drainage, before and during construction work is very important.

Applications

Sump water removal
Dewatering

Flood Control

Our pumps, due to their high performance and portability, are effective to provide quick solutions in case of flood emergency

Applications

Emergency

Farm Irrigation

Farms use Appalachian surface pumps as farm irrigation pump systems. These pumping stations transfer water via these high-pressure pumps from an irrigation canal and distributed it to irrigation sprinklers in farm fields. Their mobility allows them to be easily moved from one location to another where necessary.
