XBSY centrifugal pump, also known as a centrifugal mud pump, is important equipment of petroleum solid control system used to convey drilling fluid with suspended particles or other liquid media with similar working conditions.
It is the best matching pump for desander, desilter, and mixing funnel and is also an ideal filling pump for mud pumps.

XBSY Centrifugal Pump Parts
LONGWELL currently has five major types of XBSY centrifugal mud pumps, SB6×8(Part List), SB5×6, SB4×5, SB3×4, and 32SB180J (Part List), with more than 80 specifications from 4kW to 75kW according to the matching power.
There are two structural forms of direct connection and belt drive, which can adapt to the needs of 50 and 60Hz power grids, and there are two standards of the metric and imperial systems respectively. There are two kinds of rotary direction: forward and reverse.
Features
- Patented Seal Technology – Service life is 6 times longer than an ordinary mechanical seal.
- High Efficiency – The impeller and pump shell port are designed with optimal streamlining.
- Long Service Life – The overflow parts are made of highly wear-resistant cast iron.
- Non-clogging – The impeller is designed with a wide flow path.
- Patented Appearance – Compact and reasonable structure .
SB series centrifugal pump is the main supporting pump for drilling fluid circulation in the solid control system of oil drilling rigs. It is the best supporting pump for desander, desilter and mixing funnel, and is also an ideal filling pump for mud pumps.
centrifugal pump SB6×8 is recommended for use with drilling rigs above 3200m
SB6×8 metric pump default direction of rotation: forward;
The different models of SB6×8 sand pumps are different in capacity, head, speed, efficiency, NPSH, power, shaft power, and motor power. Here are the three models of SB6×8 sand pumps:
SB6×8J-13 capacity 240m3/h, head 37m, speed 1480rpm, efficiency 67%, NPSH 2.5m, shaft power 36kW, motor power 75kW
SB6×8J-12½ capacity 200m3/h, head 36m, speed 1480rpm, efficiency 66%, NPSH 2.5m, shaft power 31kW, motor power 55kW
SB6×8J-12 capacity 200m3/h, head 33m, speed 1480rpm, efficiency 64%, NPSH 3m, shaft power 28kW, motor power 45kW
