A hydraulic pressure booster device suited for increasing in-line fluid pressures comprises the assembly of a vertically oriented, tubular, closed end, housing for a submersible fluid pump. The pump is secured to a cap flange which closes the top of the tubular housing, while the bottom of the tubular housing is closed with either an anchor plate or blind end cap. Compression seal fittings are used to seal the penetration of pump motor pump lead wires through the cap flange. Inlet flow received into the tubular housing is drawn through the submersible pump with a resultant increase in hydraulic pressure at the output. A housing pressure sensing switch interrupts pump operation to prevent pump damage during periods of low fluid level in the housing. Additional pump protection is provided via a pump outlet pressure monitoring switch which regulates the pump delivery pressure. Dimensional design features of the device enhance useability and maintainability.

A hydraulic pressure booster device for increasing in-line fluid pressures, comprising: a submersible fluid pump driven by a submersible electric motor, said pump and motor being structurally combined as an integrated pumping unit, fluid containment means for pressurized immersion of said integrated pumping unit, fluid supply means for substantially completely filling said containment means with pumped fluid at a first pressure greater than atmospheric pressure, fluid outlet means for discharging said pumped fluid from said submersible pump at a second pressure greater than said first pressure, motor protection means for monitoring the presence of the pumped fluid pressure within said containment means and disabling said submersible electric motor when a low threshold fluid pressure level is sensed, and, motor control means responsive to said second pressure to operate said pump and motor when said second pressure is below a first threshold and to disable said pump and motor when said second pressure rises above a second threshold greater than said first threshold.
