Pot and pan washers and glass washers also fall into this market area. Pot washers may demand a higher pressure
than the NPO can provide, but they are good prospects for an SSH. Glass washers are becoming more popular as
an appliance for bars due to the increase in sanitary regulations. These units are designed to fit under the bar and
are good prospects for the NPO.
COMMERCIAL LAUNDRY
Commercial clothes washing equipment is another good application for the NPO. These systems are typically set
up as a series of wash and rinse stations with one pump per station. Due to the detergents, chlorine bleaches, fab-
ric softeners and other chemicals used in these systems, stainless steel is the preferred material for all components
exposed to the liquid. In addition, most systems have several filters to remove lint. Despite this, the pump is usually
exposed to a fair amount of lint and dirt which can clog up impeller vanes. To avoid this problem, an open impeller
is preferred.
A variation of the standard systems involves ozone injection to reduce the amount of detergents needed to clean
the clothes. NPE pumps with viton elastomers are already being used in this service since the lint would not enter
the ozone injection system.
Larger versions of dry cleaning and laundromat type machines may also be prospects for the NPO, although many
use smaller pumps.
Primary benefits of the NPO in commercial laundry applications include:
— Reduced maintenance due to elimination of lint clogs.
— Chemical resistance of 316L stainless steel and 316 cast pump components.
— Lower cost and lighter weight than typical cast stainless alternatives.
