Construction

Resistant and compact pumps for niche applications

In some types of construction sites, you have to deal with solid waste that is dissolved in water and then transported elsewhere.

Dragflow hydraulic and electric pumps, reliable and robust, are successfully used in tunneling operations and in large construction works.

A niche application where the supply of Dragflow products has proven to be fundamental is that of bentonite mud.

Dragflow pumps can handle very dense sludge and, thanks to their compact size, they adapt to even the most difficult contexts.

TUNNELING

When tunneling, large amount of cuttings are coming from the drill face. Given the nature of tunneling, this waste is usually mixed with water and treated as a pulp.

This creates the need to have a solution in place that can efficiently pump the more dense cuttings that dewatering pumps can’t manage, out of the work area to keep the tunnel free.

Compact and reliable solutions such as the Dragflow electric pump range can be the perfect fit for this application.

FOUNDATIONS: BENTONITE RECYCLING

When large trenches are dug in construction sites, it is imperative that the walls of the trench itself do not collapse and close the work site. Bentonite is a mixture of clay and water that due to its physical properties creates a support layer for these trenches avoiding their collapse.

Bentonite is pumped into the trenches to keep the walls firm but as it mixes with the soil, it loses its physical properties and its ability to support the walls.

It is then necessary to keep the bentonite clean and circulating into the trench. The used bentonite is pumped out using one a Dragflow pumps pump into a filter that then returns the clean bentonite into the shaft, providing the required support to the walls.
