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
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
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
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 212o
F. Viton® seals and Teflon® 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.
