The centrifugal single-stage E-Cul pumps are designed to transport chemically aggressive liquids. The working wheel is mounted console on the horizontal shaft by means of two rolling bearings installed in the support stance (bearing housing). -serif; font-size: medium; text-align: Justify; " />
For hydraulic unloading of the omentum, the operating wheels of the pumps are made with reverse blades, which provide minimal pressure in front of the oil seal. The shaft of the shaft of all pumps is provided by an oil seal and graphite-anti-bastle seals. For various cases of operation, a hydraulic ring is provided with the possibility of planting under pressure, which blocks the path of aggressive. A special collective box of artificial material is provided for collecting leaks.
The characteristic features of the design are as follows: in pumps of the "E-kul" type of absorption and the spiral housing are structurally combined into one case, which is an advantage of operation and repair. The working wheel is closed type and is mounted to the shaft with a shaped nut, in which a seal with a round section is installed to protect the shaft from corrosion.
Pass details that come into contact with aggressive liquid are made of stainless steel. The supporting of the pumps is made of cast iron, and the fasteners of steel with additional surface treatment.
