| | Name:XBD-dl（dlg）Fire-fighting Pump | | Title: | Codename:General introduction: Type XBD-dl(dlg) pumps is vertical multi-stage centrifugal pumps to pump water for fire-fighting .Two kinds of structure are persistence pressure (with bleed piping) and the constant pressure (without bleed piping). The relationship between capacity and head of centrifugal pump is flow decreases, head gradually raises, when flow is zero, head is the highest. At the beginning of fire alarm, hydraulic giant etc. haven’t completely been used, but main fire-fighting have been started. Because of lower capacity, the inner pressure of the pipeline network rise, pipe fitting, water hose bursting or fire-fighting lance can’t use because of excess water pressure. To prevent the pump rotor part from rusting for long-term out of service, this product s have treated against rust for the possibly rusty parts. The meaning of pump type: e.g. XBD4.3/10-65DL?3。4.3一rated pressure(1OX O.43MPa)，1O一rated capacity(L／S).
