SB series centrifugal pumps(sand pumps) are supplementary pumps, newly designed and manufactured according to features of petroleum and natural gas drilling equipment. Such pumps, adopting axial suction structures and using wear-resistant cast iron for flow-passing parts, applicable to deliver corrosive drilling fluid (with suspended particulates) or other liquid media under similar work condition, are the best optional pumps of desander, desilter and mixing hoppers as well as perfect perfusion pumps of mud pumps. For design of their parameters, that equipment with which such pumps are used together can operate under the best work condition has been fully considered. These pumps are mainly characterized by good versatility and exchangeability of parts, less leakage of shaft seal, reliable operation, long service life and convenient maintenance.
SB series centrifugal pumps are of five types, namely, SB8×6, SB6×5, SB5×4, SB4×3 and SB3×2, of which, SB8×6 matches motors (45kW, 55kW & 75kW) (forward pumps and reverse pumps of 6 specifications can be provided according to customers’ demands), SB6×5 is for motors (22kW, 30kW, 37kW and 45kW) (reverse pumps of 4 specifications); SB5×4 can be used with motors (15kW and 22kW) (reverse pumps of 2 specifications); SB4×3 is applicable for motors (15kW, 11kW and 7.5kW) (reverse pumps of 3 specifications); SB3×2 matches motors (11kW, 7.5kW & 5.5kW) (reverse pumps of three specifications). Sealing components of the former two types pumps are universal. Outline and installation dimensions of reverse pumps are the same as those of forward pumps on the whole, except that volute discharge tube is at left side of forward pump but at right side of reverse pump (seeing from the suction end).
Sealing of SB series sand pumps is mechanical seal, Main seal is high wearing hard alloy mechanical seal that is with a long life; auxiliary seal is graphite packing seal that can avoid accidents. The practice has demonstrated that SB series sand pump seal is reliable and convenient for maintenance.
Shaft seal of SB series sand pumps is lubricated with grease, and bearings are lubricated with oil. In addition, bearings can also be lubricated with grease (bearing caps at two ends of bearings are equipped with grease holes).
Both inlet flanges and outlet flanges of SB series sand pumps are with two series standard dimensions, in metric system for domestic users and in English system for foreign users.
Our SB series sand pumps have been used for land and offshore drilling platforms in more than 20 countries over the world, and the result shows that these pumps requires little maintenance expenses other than the normal replacement of sealing components.
