    PEHD membrane sealing systems for basins

    For reasons of environmental protection, basins often need to be leakproof, e.g. seepage basins on landfill sites. However, it can also be important to ensure, for example, that valuable water does not escape into the subsoil undetected.

    Hose pumps for copper mining industry

    Copper tailings - slurry is very abrasive. Centrifugal pumps with soft packing shaft seals had to be water-flushed to limit wear on the shaft sleeve. Fine until winter froze the water. Solution: a Albin Pump ALHX80, with no seals to wear out. Tailings could be continuously pumped at higher concentrations!, doubling plant efficiency. Downtime: a few minutes every 2,000 hours to change the tube.

    PEHD membrane sealing systems for retrofitting in existing landfill site

    It is also possible to retrofit a monitoring system in existing surface sealing liners without impairing the synthetic liner sheet or the immediately adjacent functional layers. For this purpose, cable trenches must be dug in the recultivation layer above the drainage layer. The detection cables are then laid in these trenches.

    PEHD membrane sealing systems for landfill surface liners

    Unlike base liners, surface liners are not buried at some point under many metres of waste and instead are usually protected over the course of many years only by a 1-metre thick mineral layer. As a result, there can be uncertainty about the integrity of their leak-proofing characteristics, particularly if the land is subsequently used for other purposes; however, at the same time, repairs are also possible at reasonable cost if the location of any damage can be established.

  • Variable frequency drive controls AC motors

    Consider integrating a variable frequency drive. It often can optimize energy efficiency by enabling you to match motor speed to the demands of the system. Look for opportunities, for example, to replace throttle valves or dampers used to restrict flow. However, a variable frequency drive may not make sense if the load on the motor is relatively small and constant — because speed changes will occur infrequently and any benefits from varying the speed will be negligible. So, thoroughly assess the system load profile to determine the scale and frequency of required speed changes before deciding about installing a variable frequency drive.

    Pumps for Paint & Ink

    Coloured and protected surfaces provide added value as paints and enamels help to make products both more interesting and increase their life. That is why they are important finishing materials where care, environmentally-friendliness and reliability are needed in their supply and correct dosage. The DESMI ROTAN® gear pumps are commonly used for paints, resins and coatings. For ink manufacturing and printing press applications, the HD series and specially fitted PD and ED magdrive pumps are being used. A leading paint factory manager, states: “ROTAN® pumps have for decades been used in numerous of our plants. The ED model was chosen due to its magnetic coupling. A magnetically coupled design, which has no rotating seals, ensures less downtime and lower operating costs. Every pump in our new facility is magnetically coupled, and thus we have eliminated the problems associated with packed glands and mechanical seals.”

    Pumps for Asphalt / Bitumen

    DESMI has a full range of different pumps and matching equipment supporting the handing of bitumen products. Including unique features suited for today’s needs and new polymer based formulations, we have the solution. For certain applications, we can offer proven sealing options, available is also a patented zero-leakage pump with a state of the art magnetic coupling. This pump offers a total protection against spillage and vapour, which may create environmental hazards. Electrical heating is an alternative to heating by liquid or steam. Applications tend to fall into four categories: Production (refining), distribution (terminals), hot mix (paving mixtures), and roofing (filled asphalts). Refineries and terminals often use steel pumps, while hot mix asphalt plants use mainly cast iron pumps with heating jacketed, and either packing or mechanical seals. Roofing plants are generally pumping highly abrasive, filled asphalts for shingle manufacturing.

    PEHD membrane sealing systems for landfill base liners

    There are several phases of preparation of landfill base liners, starting with the positioning of the membrane, until these can be covered with several metres of refuse. These membranes may be damaged during preparation, but can also be inspected and repaired. It is advisable to undertake inspections at regular intervals.
