NEMO®
Pump Components
All
Standard NEMO® Pumps include the following typical
components:
|
|
1
|
DEEP-GROVE
BALL BEARINGS have a calculated B-10 life of greater than
100,000 hours. (Back to Illustration)
|

2
|
SHAFT
SEALING variations, including packed stuffing box complete
with lantern ring and grease zerk, mechanical seal, or special
seals are located on a solid drive shaft with a short overhang
which minimizes shaft runout. The window area of the pump is
increased to allow easy access to the stuffing box. Cast iron
pumps are supplied with a packed stuffing box. Stainless steel
pumps come standard with a hard faced single mechanical seal.
Other options are available. (Back to Illustration)

SOLID
DRIVE SHAFT eliminates any possibility of solids build-up.
Unlike hollow shafts, material cannot accumulate or cause clogging.

DRIVE
SHAFT joint head is removable. By taking off the universal
joint head, the
shaft seal can be removed and re-assembled without drive shaft
removal. (Back to Illustration)

|
SUCTION
HOUSING FLANGE can be rotated to any of four positions in
90º increments. (Back to Illustration)
|
|
6
|
CONNECTING
ROD is extra long for extremely low angularity, resulting
in less
loading on the universal joint which provides longer joint life.

7
|
TWO CLEAN
OUT PORTS come standard on larger pumps with a cast iron
housing. Clean out ports are available on pumps with other metallurgy
as an option. (Back to Illustration)
|
|
8
|
DRAIN
PLUG is located at the lowest point on the suction housing.
This allows for the housing to be completely drained. (Back
to Illustration)
|
|
9
|
UNIVERSAL
JOINTS are SM pin-type or double sealed joints on certain
sizes. Sealed pivot-type joints available on larger pumps. (Back
to Illustration)
|
|
10
|
ENLARGED
SUCTION HOUSING at the rotor end for non-restricted flow
of heavy materials. (Back to Illustration)
|
|
11
|
THRU-BOLT
CONSTRUCTION for easier maintenance, stator removal/installation.

|
|
12
|
STATORS
are available in a wide range of materials including natural
or synthetic rubbers, cast iron, stainless steel, a wide variety
of rigid plastics, and others. The inlet side of the stator
is chamfered to allow for unobstructed uniform feeding to the
rotor and stator elements. Gaskets are an integral part of the
stator on non-rigid materials. (Back to Illustration)
|
|
13
|
ROTORS
are available in a broad range of materials including hardened
tool steel, chrome plated hardened tool steel, stainless steel
and others with optional chrome plating. NEMO CERATEC®
is also available in various sizes. (Back to
Illustration)

ACCESSORY
CONNECTION is threaded to allow the attachment of measuring
instruments or can be used for draining. The connection can
also be rotated in 90º increments and can be used for gauges
or other instrumentation. Accessories can be added in any position.

DISCHARGE
FLANGE is a standard connection matched to the individual
pump discharge pressures. Flanges are sized to ensure self-cleaning
velocities essential when pumping sludges and slurries. Flange
can be rotated in 90º increments. (Back to Illustration)
