CONTENTS
GEAR........................................................................
The positive displacement gear pump design is self-priming and known for smooth, repeatable, metering
pump-like dependability for pumping clean, non-abrasive liquids from low to high viscosity.
FLEXIBLE IMPELLER.....................................................
The positive displacement flexible impeller pump design is self-priming, capable of solids handling,
and has a gentle, low shear pumping action for thin to viscous materials. This design is extremely
economical and versatile.
DIAPHRAGM/OSCILLATING.............................................
The positive displacement diaphragm and oscillating pump designs are self-priming and utilize
reciprocating action to move liquid. Diaphragm pumps will handle thin to viscous liquids with low to
high solids content. The extremely compact oscillating pump will move low volumes in dispensing,
circulating or spraying applications.
PROGRESSING CAVITY / PERISTALTIC ...............................
These self-priming, solids handling positive displacement pumps are capable of pumping thin, viscous
liquids and particle laden fluids. Progressing cavity pumps deliver a pulse-free repeatable flow for
normal and shear sensitive liquids. Peristaltic pumps totally isolate the fluid within the hose they
utilize and squeeze it through to the discharge.
VANE / ROLLER ..........................................................
The self-priming, positive displacement vane and roller pump designs utilize rotary motion to move
liquid at low to medium pressures. The vane pump handles clean liquids with thin to medium viscosity
while the roller pump design is ideal for handling small abrasives suspended in thin liquids.
CENTRIFUGAL............................................................
47-76
The centrifugal pump design is not positive displacement. It utilizes centrifugal force to move liquid
and while not normally self-priming, they are available with integral priming chambers that add
self-priming capabilities. Centrifugals are ideal for recirculating or transfer of low viscosity liquids in
low head, low to high volume applications. High head is possible with multistage versions (see high
pressure section).
HIGH PRESSURE..........................................................
77-86
High pressure pumps utilize the diaphragm, plunger, piston, turbine or multistage centrifugal designs.
Diaphragm pumps can handle thin to viscous liquids that are clean or abrasive (slurry versions available)
at medium to high pressures. Plunger, piston, turbine and multistage centrifugals will handle thin clean
liquids at medium to high pressures.
DRUM, TRANSFER AND METERING ...................................
These pumps utilize a variety of pumping principles to dispense, dose or meter thin to viscous liquids
that are clean, abrasive, volatile or corrosive. Drum pumps are designed to dispense liquid from barrels,
totes or other containers. Metering pumps are available with manual or electronic controls that will
variably and precisely supply liquids.
SUBMERSIBLE / CONDENSATE .......................................
99-108
These pumps typically utilize the centrifugal design. Submersible pumps are available in manual
or automatic operation and are capable of handling some solids. Condensate pumps automatically
evacuate accumulated liquid from a collection reservoir.
SPECIALTY ..............................................................
109-126
Specialty pumps encompass pumps that have been applied in narrow markets to perform very
specific tasks. This section includes pool, well, well test, machine tool coolant, carpet cleaning, film
developing, heliarc welder coolant, remediation, hot water boosters, closed loop recirculators, and
OEM aftermarket replacements.
HYGIENIC / SANITARY...............................................
Hygienic/sanitary pumps utilize a wide array of pumping principles manufactured to 3A, USDA or FDA
cleanliness standards to move any fluid required for food, cosmetic, beverage, pharmaceutical or
bioprocess applications.
TECHNICAL INFORMATION.........................................
This section includes friction loss and conversion tables, viscosity charts, pump related formulas and
pumping principal descriptions.
