SB series 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.\\\\r\\\\n \\\\r\\\\nThese pumps are mainly characterized by good versatility and exchangeability of parts, less leakage of shaft seal, reliable operation, long service life and convenient maintenance.\\\\r\\\\n \\\\r\\\\nSand Pump Type and Representative Meaning:\\\\r\\\\nSB—SB seriesSingle-stage single-suction sand pump\\\\r\\\\nF—Reverse rotation (Watch directly toward pump inlet, pump rotates anticlockwise; pump outlet is\\\\r\\\\nlocated at right side of the vertical central line of pump inlet)\\\\r\\\\nZ—Forward rotation(Watch directly toward pump inlet, pump rotates clockwise; pump outlet is\\\\r\\\\nlocated at left side of the vertical central line of pump inlet)\\\\r\\\\nJ —Mechanical seal\\\\r\\\\nP —Belt drive\\\\r\\\\nC —ANSI flanges\\\\r\\\\nHere are three code of numeric, pump inlet diameter, pump outlet diameter, nominal diameter of impeller or motor power.\\\\r\\\\n\\\\r\\\\nNotes:\\\\r\\\\n1. These pumps shall be used only within the design scope.\\\\r\\\\n2. This pump employs mechanical seal as its primary seal and packing seal as its secondary seal. Packing seal can be compacted only when mechanical seal is disabled. Otherwise, the seal may be damaged.\\\\r\\\\n3. No-load running time of the pump cannot exceed 5s. The pump must run under the condition of being filled with liquid. Otherwise, the mechanical seal may be damaged.
