"We purchase bareshaft pumps from Hughes from 500 to 2750 bar which we supply into the Taiwanese & Chinese markets. We find the quality & after sales support excellent"

Z.H.Hou, Executive Director
Pumpson Systems, Taipei, Taiwan

The data below is a summary of performances for the pump range. The Ultrabar range of pumps are only offered with one plunger size so flow & pressures shown are possible together.

The other pumps are offered with a range of plunger sizes, shown below is a summary of extreme flow & pressure options for each pump, not possible together.

Maximum flow is achieved by using the largest plungers & maximum pressure is achieved by using the smallest plungers. All figures are nominal, for precise options refer to individual data sheets by clicking on the PDF icon of the pump or model number.
