FLEXIBLE
IMPELLER
How It Works:
A. Flexible impeller blades, upon leaving offset cam,
create a nearly perfect vacuum for instant self-priming
B. As impeller rotates, each successive blade draws
liquid and carries from intake to outlet port
C. As flexible impeller blades contact the offset cam
they bend with a squeezing action that provides continuous,
uniform flow.
FEATURES:
Versatile - The flexible impeller pump combines the
priming feature of positive displacement type pumps with the
general transfer ability of centrifugals. It will pump either
thin or viscous liquids - can handle more solids in suspension
than other types of rotary pumps. It operates at low or high
speeds - can be mounted at any angle and pumps in either
direction with equal efficiency.
Self-Priming - Pumps instantly with dry suction lifts up
to 10 feet; up to 25 feet when wetted. Permits cleaner, safer
installation. No foot valve required.
Simplicity - One moving part - a tough, long-lived, wear
resistant flexible impeller lubricated by the liquid being
pumped. No metal-to-metal pumping action - no gears to jam,
clog, or become noisy.
More Capacity - Flexible impeller pumps, in general
require less space because they deliver greater flow for weight,
size and price than other types of pumps. |
CENTRIFUGAL
How It Works:
A. Liquid enters inlet port of pump. Level of liquid must
be high enough above the pump for gravity to push it into pump
or pump must be initially primed.
B. Rotating impeller gives velocity energy to the liquid
moving it to the periphery of the volute casing and towards the
discharge port.
C. Volute casing discharge arrangement converts velocity
energy into static pressure or available pump head. Flow rate is
dependent upon restrictions in the inlet and outlet piping and
the height change and the liquid needs to be moved.
FEATURES:
High Volume Flow - Centrifugal pumps handle high volumes
with a smooth, non-pulsating flow. The flow rate can be
regulated from maximum output to no flow with no damage to the
pump. An excellent pump for general transfer applications.
Low Maintenance - Wear due to operation is minimal.
Easily disassembled for quick service. Few moving parts
Easy Installation - Compact size. Discharge port can be
rotated to various positions for ease of piping. |

DIAPHRAGM
How It Works:
A. As diaphragm rises, liquid is pulled into pump
chamber, while outlet valve is pulled closed.
B. When diaphragm comes down, the liquid is forced
through the outlet valve, while the intake valve is pressed
shut.
C. Diaphragm pumps can have single or multiple chambers,
with smoother flow the result of more chambers.
FEATURES:
Run Dry Ability - Diaphragm pumps do not depend on pumped
liquid for lubrication, thus can be run dry without damage.
Self-Priming - Liquid can be lifted up to six feet, with
no need for external check valves.
Versatile - The compact size, low power requirement, and
quiet operation make it the ideal pump for many marine
applications. |
VANE
How It Works:
A. Vanes, upon leaving eccentric portion of liner create
a partial vacuum for priming.
B. As rotor rotates, each successive vane draws and
carries liquid from intake to discharge port.
C. When the vanes again contact the eccentric portion of
the liner, they force liquid out the discharge port.
FEATURES:
Durable - heavy duty construction in quality materials
gives long life. Body is designed to resist environmental
damage. The vanes and rotor are constructed of a wear resistant
long life material.
Self-Priming - Liquid can be lifted up to three feet for
self-priming. Permits less complicated and more economical
installations.
Simplicity - Few moving parts to replace. Maintenance is
as simple as loosening three screws. Rotor, vanes, and seal are
lubricated by the liquid being pumped.
Versatile - Excellent compact unit for general utility or
transfer applications. Wil pump thin or somewhat viscous
products. Can be mounted at any angle and run in either
direction. |
