BW450 Triplex Piston Mud Pump
The BW450 is a horizontal, three-cylinder, single-acting
reciprocating piston mud pump designed to deliver flushing fluid
during geological core drilling and prospecting. Its four-speed
configuration provides flow rates from 172 to 450 L/min at
pressures from 2 to 5 MPa. The pump can handle water and drilling
mud, and its compact, 520 kg construction supports transport to
remote or mountainous work sites.
Key Features
Four Speed Settings for Flexible Flow and Pressure
The BW450 offers four pump speeds, with corresponding flow rates of
172, 240, 340, and 450 L/min and pressures of 5, 4, 3, and 2 MPa.
This range lets operators select a suitable operating point for
different drilling conditions and flushing requirements.
Triplex Single Acting Piston Design
The horizontal three-cylinder arrangement delivers reciprocating
fluid flow for drilling operations. With a 100 mm stroke and 95 mm
cylinder diameter, the pump is specified for supplying water or mud
to help circulate drilling fluid, carry cuttings to the surface,
and cool and lubricate drilling tools.
Handles Water and Drilling Mud
The pump is designed to discharge both clear water and thick mud.
When used with a drilling rig, circulating mud can help support the
borehole wall while transporting rock debris out of the hole.
Compact Construction for Site Transport
The pump measures 1000 × 995 × 650 mm and weighs 520 kg. Its
relatively compact footprint and stated light weight make it
suitable for transportation to constrained or mountainous drilling
locations.
Suitable for Drilling and Cement Grouting Work
Beyond flushing-fluid supply for core and prospecting drilling, the
source material also identifies cement perfusion as an application.
The four operating settings provide flexibility for projects with
different fluid delivery requirements.
Applications
- Geological core drilling and prospecting
- Geotechnical investigation and geological exploration
- Coal and ore exploration
- Small-diameter water well drilling
- Geothermal heat pump pipe installation
- Small-diameter foundation piling
- Construction drilling for railway, road, port, bridge, tunnel, and
water conservancy projects
- Cement grouting or perfusion work

Frequently Asked Questions
What type of pump is the BW450?
It is a horizontal, triplex, single-acting reciprocating piston mud
pump.
What are the BW450's flow and pressure ranges?
The four listed settings provide flow rates of 172, 240, 340, and
450 L/min, with corresponding pressures of 5, 4, 3, and 2 MPa.
Can the BW450 pump water as well as mud?
Yes. The source material specifies clear water and drilling mud,
including thick mud.
What drilling depth is the BW450 suitable for?
The source material gives conflicting depth references: one section
mentions use with a drilling rig up to 1800 m, while another
describes prospecting drilling below 1500 m. These figures are not
presented here as a confirmed pump drilling-depth rating. Actual
drilling depth depends on the complete rig setup and operating
conditions.
What are the suction and discharge hose sizes?
The listed suction hose diameter is 76 mm, with a 3-inch pressure
hose noted. The discharge hose diameter is 51 mm, with a two-layer
steel high-pressure hose noted as 2 inches. Confirm hose
connections and specifications for the intended setup before
ordering.
Is the BW450 self-propelled?
The provided information describes the pump itself and does not
specify an integrated travel chassis or self-propelled
configuration.
What power source does it require?
The specification lists 22 kW power and an input speed of 500
r/min. The drive or engine configuration is not specified.
What after-sales support is included?
The source describes technical data, maintenance and
troubleshooting guidance, preventive measures, OEM spare parts,
installation instructions, packing lists, manufacturer
instructions, qualification documents, and a warranty certificate.
It also states that service is intended to continue through the
equipment's working life.
