Description

Pressure booster pumps increase water pressure from city mains or private water sys-
tems. 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.  Stainless steel models can handle salt-water and 
contaminated water in reverse osmosis filter and other aggressive water applications.

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 care-
fully for any damage that may have 
occurred during transit.

NOTE

:  Use pump with clear water 

only.
