Each row is one matched operating setting. Maximum flow and maximum pressure occur at different settings.
Pressure gauge and air chamber
A circular pressure gauge is positioned above the vertical air chamber, with the fluid connections arranged at the pump head.
15 kW electric drive
The 15 kW electric motor and pump sit on a common base. A belt-and-pulley drive connects the motor to the reciprocating pump assembly.
DR-350B Mud Pump for drilling-fluid circulation
The DR-350B Mud Pump supplies flushing fluid to geological core boreholes. The horizontal triplex design uses three single-acting pistons, with an 80 mm cylinder bore and a 100 mm stroke. The electric motor is rated at 15 kW.
Four matched flow and pressure settings
Four operating settings provide different combinations of pump speed, delivery and rated discharge pressure:
- 250 L/min at 2.5 MPa — 200 strokes/min
- 145 L/min at 4.5 MPa — 116 strokes/min
- 90 L/min at 6 MPa — 72 strokes/min
- 52 L/min at 6 MPa — 42 strokes/min
Maximum flow and maximum pressure occur at different settings.
Electric drive and pump assembly
The electric motor and pump are mounted on a common base. A belt and pulley transmit the drive to the pump. The horizontal pump body places the fluid end alongside the drive assembly, while a circular pressure gauge sits above the vertical air chamber.
Fluid connections
The inlet pipe diameter is 76 mm and the outlet pipe diameter is 51 mm. The pump is used to deliver flushing fluid during core drilling and can also serve grouting and liquid-transfer applications.
