LIQUIDS:
The special pump alloys used provide corrosion resistance
to many liquids including water, water solutions, and a wide
range of commercial chemicals. Questions as to the chemical
compatibility of special liquids should be referred to the factory.
Viscous liquids with a maximum viscosity of 2000 Saybolt
Seconds Universal can be pumped. However, when pumping
viscous liquids as compared with water, a reduction in flow and
pressure occurs and the required horsepower rate increases.
Liquids heavier than water require additional horsepower in
direct proportion to the increase in specific gravity. Liquids
contaminated with small solids or abrasives can be handled,
but a reduction in mechanical seal life must be expected.
CHARACTERISTICS:
This close-coupled pump uses a standard NEMA C-Flange Jet
Pump Motor with weld-on base and threaded shaft end to
accept the pump impeller. Single phase motors are non-reversible and are wired for the proper pump rotation which is counter-clockwise looking at inlet end of pump. See the dimensional
drawing on back. Three phase motors must be checked out for
proper rotation when pump is installed. Interchanging of any
2 wires in a 3-phase system will reverse motor rotation.
The pump uses a mechanical type shaft seal with a Buna
rubber element. It is suitable for water, oils, and some mild
solvents and it is limited to 212°F. Viton® seals are available for
severe solvents, difficult chemicals, and elevated temperatures.
These centrifugal pumps are not self-priming. They must be
installed below the liquid level so that the liquid flows to the
pump by gravity (flooded suction). However, if a foot valve is
used at the beginning of the suction line, and all air is bled
from the pump by manual priming, the pump will lift on the
suction side up to 15 feet. Such a system relies entirely on the
non-leaking foot valve for starting capability.
The flow of a centrifugal pump can be conveniently controlled
by a throttling valve in the discharge line without the need for
a relief valve. In centrifugal pumps, the horsepower demand
will decrease as the pressure increases. Maximum horsepower
occurs with a wide open discharge.
