United Pumps Australia

– Single stage overhung radially split casing, heavy duty support feet, stiff shaft design, end suction or top suction arrangement.
– High suction pressure/high temperature applications (e.g. boiler circulators) can be accommodated with special features.
– Back Pull Out construction allows removal of the pump end without disturbing inlet / outlet piping.
– Optional air cooling available for high temperature applications.

– Single stage, axially split casing, double volute, double entry impeller.
– Suitable for moderate to large flow rate with moderate head applications.
– High suction pressure/high temperature applications can be easily accommodated.
– The axially split design allows the complete rotating element to be balanced as an assembly prior to installation in the casing for excellent rotor dynamics.

Single stage, radially split casing, double volute, double entry impeller.
– Suitable for moderate to large flow rate with moderate head applications.
– Double suction impellers provide excellent suction performance.
– Axially balanced for high suction pressure applications.
– High temperature services are easily accommodated with a range of cooling options and the rugged centerline mounting.

Two stages for moderate head applications.
– Both top suction / top discharge (on the same side) designing and adapting to suit client specifications configurations are available.
– High suction pressure and high temperature can be accommodated easily.

– Two stages for moderate head applications, double-entry first-stage impeller to suit low NPSHA cases.
– Both side suction / side discharge (on the same side) configurations are available.
– Designed for high suction pressure pipeline and process services.

Multi-stage, axially split casing, double casing volute, opposed impeller arrangement (for axial hydraulic balance, eliminating high thrust loads on the bearings), single or double entry first-stage impeller.
– Used extensively in high-pressure applications such as refinery process pumps, transfer pumps, water injection pumps, pipelines pumps, BFW pumps, offshore MOL pumps.
– Axially split design allows the rotor to be replaced with a spare assembly without removing the pump from the piping.
– Rotating element can also be balanced as a complete assembly prior to installation.

– Multi-stage, double casing (barrel), double casing volute, opposed impeller arrangement (for axial hydraulic balance, eliminating high thrust loads on the bearings), single or double entry first-stage impeller.
– Axially split inner cartridge design also allows replacement of the pumping assembly in situ.
– Ultimate option in low SG and/or high temperature applications where pressure is extremely high.

Single stage, vertical inline configuration.
– Close coupled vertical pumps, most commonly supplied in extended motor shaft form (OH5) providing an extremely rigid and reliable shaft assembly.

– VCMS / VMS (volute case)
– VCD (diffuser case)
– Canned pumps with single stage or multi-stages
– Typically used in very low NPSHA applications and in cases where space on site is limited.
– Reliability is assured by using proper modern composite materials for shaft bushings.
– Can also be used as sump pumps without the suction can.

Discharge through the central column lubricates the shaft seal
– Radially Split Casings and column joints with confined gaskets
– Thrust can be taken by the driver or a separate bearing housing
– VS1 / VS2 / VS3 available with a gasketed footplate for installation in a pressure vessel
– VS6 / VS7 suction barrel or “can” can be extended to facilitate deep first stage placement for very low NPSHR
