information that the inputs and telemetry units provide, plus additional options of site location( map and satellite views), photos of the site equipment, historic charting, alarm history, individual level signals or operational status.“ Complementing our on-site service and reagent supply, BASF’ s remote monitoring solution provides you with industry-leading technical support.” Telemetry features and benefits include:
■ The telemetry device provides continuous remote-access to plant operating data. Readily accessible real-time process measurements allow a higher level of support from BASF for optimising performance.
■ For increased plant reliability; the telemetry unit can send alarm notifications to prescribed recipients via SMS and email transmissions. This allows the BASF team to provide a rapid service response for any operational issues.
■ BASF can assess inventory levels at any point in time, allowing both product performance tracking and stock management.
Pump challenges in phosphates
A major mining group in Morocco, one of the leading companies in the world market for phosphates and its derivatives, operates several large production sites and chemical complexes. At one of its sites ABEL says its reliable HPT triplex plunger pumps are used for gland seal water supply. The slurry pumped from the mine is stored in various high volume tanks for subsequent distribution to the 10 independent production units. In order to ensure non-stop pumping, the mining company has 10 pumping lines and another five in reserve. The product is pumped by different centrifugal pump series on each line. Each series is made up of one, two or three centrifugal pumps depending on the pumping characteristics( flow, pressure) required on each line. At present there are over 40 centrifugal pumps with variable flows and maximum limits close to 300 m ³/ h and maximum pressure limits of 30 bar.
In order to ensure the mechanical sealing of the centrifugal pumps, a precise amount of water is needed in each pump to clean and cool the seal. The water flow in each sealing action should cause pressure of approximately 0.5 bar above that of the centrifugal pump impulsion.“ It must be borne in mind that as the seals wear out, the water supplied to generate the required pressure must be greater, apart from the pressure variations in each centrifugal pump depending on the features of the pumped product and its flow.”
Another important aspect of this application to be taken into account is the fact that each triplex HPT ABEL plunger pump will supply the flow needed to carry out the correct sealing for up to a maximum of six centrifugal pumps at the same time.
“ All these variables have made the mining customer opt for the robustness of the ABEL model HPT positive displacement pump, which apart from being highly reliable offers great precision in the water flow supplied to the pump at every moment. Each HPT pump is capable of adjusting to a

THINK LONG-DISTANCE TRANSPORT IS INFRASTRUCTURE- INTENSIVE. WE THINK DIFFERENT.
Transporting materials from remote locations has traditionally required significant infrastructure investments in road or rail links, vehicles, personnel and fuel. BEUMER offers an economical, efficient and environmental alternative – long-distance overland conveying. This gives you a dedicated, around-the-clock transport link at the fraction of the cost of infrastructure development. The reduced noise and air pollution minimises environmental impact and improves personnel safety. Add to that a high degree of design flexibility and customisation and you can see why overland conveying makes a big difference to operational efficiency and environmental protection.
