The Pump RANGE
Designed to comply generally with the requirements of API Standard 674, our positive displacement, reciprocating power pumps are capable of discharge pressures up to 2750 bar (40,000 psi) and flow rates to 773 lpm (46.4 m3/hr / 7003 bpd / 205 usgpm).
They complement the Hughes manufactured Dualway range of API Standard 675, controlled volume positive displacement pumps, to provide ratings from 0.37 to 375 kW (0.5 to 500 hp).
The pumps are ruggedly constructed and produced in nine frame sizes, each including a range of plunger sizes. This allows selection of the ideal pump for the job, with a compact design, high power to weight ratio and a choice of construction and seal material to suit the specific application.
In addition to the more common triplex pump layout, five cylinder versions offer reduced flow variation for applications requiring minimum pulsation (see photo of pressure gauge above right). Close-coupled reduction gearbox drives are available, with a choice of gear ratio to suit most prime mover speeds.

Construction
The power end of the pump features robust cast iron casings with splash or pressure lubrication and oil cooling, according to the application.
Stainless steel is the standard material used for the fluid end with alternative materials such as Duplex or Aluminium Bronze available for increased corrosion resistance in more specialist applications. The in-line valve arrangement widely used throughout the range prevents the adverse effects of cyclic stress within the head block, while allowing all working components to be easily removed on site for service and maintenance. The latest plunger seal materials are employed with the facility for seal flush or seal lubrication and solid ceramic plungers extend the life of the self adjusting plunger seals.
Scope of Supply
We can deliver and commission from a bare shaft pump to a complete skid mounted set, ready for operation in safe or hazardous areas (ATEX compliant where required), using electric motor or diesel engine prime movers. Pump sets can be supplied in certified offshore crash frames or containers, with or without acoustic dampening.
Ancillary equipment available includes pulsation dampers, relief and loading valves, directional control valves, filtration and condition monitoring, all backed by a comprehensive spares stockholding, service engineers and worldwide network of sales / service agents.
