Envirotech Engineering Ltd is dredging pump and excavators supplier for clay and sand dredging operations.
We have well built dredging tools for contractors and construction companies. They are built to resist.
In the market there are similar dredging tools from other well known manufacturers but these ones are made to last.
The dredging tools are generally assembled to the regular excavators or secured to an hydraulic winch or electrical winch being part of a pontoon.
Small local dredging tasks can be easily carried out with these products.
This new way to utilize your excavator as a suction dredger creates new business and keeps the machinery busy.
There are always more than one technical solution speaking about the equipment for the same problem; It may work and perform in different settings, and accept solids of very large diameter.
We have small dredging sets such as these ones:
or more Heavy duty dredging sets such as below:
The excavators are equiped with electrical or hydraulic motors from 7,5 kW to 37 kW
The hydraulic dredging pumps from 10KW to 220 kw MEANS sand or clay slurry volumes pumped from 100m3 per hour to 1000 m3 per hour
