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)

3

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

4

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)

5

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. (Back to Illustration)

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. (Back to Illustration)

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.

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)

14

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. (Back to Illustration)

15

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)
