The project: rainwater harvesting on the coast of Morocco
Even in a relatively dry country like Morocco, severe storms can still be an issue. When they hit, a fast and reliable method of rainwater harvesting is essential for proper flood control. Water treatment may also be required. To serve these needs, a rainwater evacuation project was implemented in Jorf Lasfar.
Located on the Atlantic Coast, Jorf Lasfar lies approximately 100 km south of Casablanca, and after Casablanca it is Morroco's second most important port.
The customer: the world's leading phosphate supplier
The "Office Chérifien des Phosphates" (OCP) with headquarters in Casablanca is the largest supplier of phosphates in the global market. Founded in 1920, the company is state-owned and extracts Morocco's extensive phosphate reserves, estimated at 85 million tonnes. The OCP Group has almost 20,000 employees spread across four mining sites and two chemical complexes. Its revenues in 2018 amounted to US$5.8 billion.
The primary contractor for the project is the SEHI Group (Société Pour L'Equipement Hydraulique Et Industriel), a leading supplier in the fields of electrical engineering, hydraulics, motors etc.
The challenge: reliable operation, even in extreme heat
Especially in a country like Morocco, where high temperatures prevail, one of the biggest challenges was finding a way to prevent the pumps from overheating. Fail-safe and efficient pumps that could stand up to the desert heat were an absolute must.
The solution: waste water pumps to meet the highest requirements
One of the main reasons for choosing KSB to supply the XX XX Amarex KRT pumps was proximity – the local KSB office was readily accessible. But ultimately, the deciding factor was the pumps' superior cooling concept.
In terms of their design, the pump motors feature a closed cooling circuit that prevents the water-glycol mixture from coming into contact with the pumped fluid as it circulates. This setup prevents the dirt particles in rainwater from clogging the pump and interfering with the cooling process.
The coolant is circulated by an innovative impeller that is integrated into the cartridge mechanical seal. The pumps can operate reliably in environments with temperatures up to 55 °C.
