WEDA D70 electric submersible pump presents Wear Deflector

These submersible pumps end up in the most varying applications that one can imagine. Not two applications are the same. The electric drainage pump must be as robust and versatile as possible. And, at the same time, it must be portable, plug-and-pump and easy to inspect and maintain.

Unplanned or impromptu downtime highly affects pump performance. Moreover, it can endanger a mine's working environment or a construction site's accessibility.

The know-how is vital to successfully design an electric submersible pump ready to face all these aspects. It is essential to have the right tools and a clear view of what is at stake. In the worst-case scenario, a flood on site can put at risk human lives and capital equipment.

When we talk about pumps, we get passionate about the nuts and bolts. To better explain the drainage electric pump hydraulic design, we have this cutaway image. The upper diffuser is in orange polyurethane, the impeller is in high chrome cast iron and the lower diffuser is in black NRB rubber.

This innovative hydraulic design is the Wear Deflector Technology. It allows an electric submersible pump to deal with sand-laden water month after month with only the slightest impact on performance. Conventional electric drainage pump designs have to walk the fine line between performance and solids-handling. However, our WEDA Wear Deflector Technology combines the best of the two worlds.

They deflect solid particles suspended in the pumped liquid. This hydraulic design prolongs the electric submersible pump life cycle and enables long-lasting pump performance.

The new WEDA hydraulic design is a major leap in electric submersible pump engineering. However, the WEDA D70 has other features to accomplish long-lasting performance. Always with ease-of-installation and serviceability in mind.

The WEDA D70 electric drainage pump has a top discharge design. It is ideal for general dewatering applications and pumping groundwater and raw water. The new WEDA model can reliably pump water with specific gravity up to 1.1. And it can handle water with solids up to 10 mm in diameter (0.39 in). 

Additionally, the WEDA drainage pumps have an outstanding power-to-weight ratio. They weigh up to 40 percent less than competitive products and have a very compact design. All this makes WEDA drainage pumps easy to handle and move around a site. The aluminum body provides strength and excellent corrosion resistance.
