Pressure booster pumps increase water pressure from city mains or private water systems.
Applications include providing high water pressure for washing buildings, dairy walls or
floors, hog parlors, poultry houses, rinsing or spray cooling equipment, lawn sprinkling and
insecticide spraying.
Single-phase models are equipped with a capacitor start, thermal protected motor. Three-
phase models require separate overload protection.
Unpacking
When unpacking the unit, inspect
carefully for any damage that may have
occurred during transit.
NOTE: Use pump with clear water only.
