Disaster relief pump

The operator of a large nuclear power plant was looking for three mobile disaster relief pumps. The pumps are supposed to cool the reactors by applying water in case of a defect in the power plant. The operator opted for three Börger rotary lobe pumps EL 1000. The customer’s decision was based on the well-known high quality and reliability of the Börger rotary lobe pumps. In addition, compared to centrifugal pumps, rotary lobe pumps have the advantage that, even at high pressures, the flow rate hardly decreases. This is important for the disaster relief pumps as they had to be pressure-resistant up to 15 bar to be able to reach the required water throw distance.
