Blowcase Pumps

PESCO Manufactures a Range of Blowcase Pumps for Use in Various Service

The blowcase pump is very well suited for moving fluids at low pressure or even atmospheric pressures and can be used to discharge liquids into a higher pressured line. Drive gas is usually taken from a high pressure source on skid. When the liquid being pumped reaches a predetermined high level, control valves are closed on the inlet and equalizing lines. A control valve on the power gas opens, blowing high pressure gas into the blowcase. The blowcase outlet, with either a check valve or another control valve, opens allowing the power gas to drive the liquids out.
