ISO 2858 / EN 22858

Industry Standard, Chemical pump

Maximum static system pressure of 16 bar (Grundfos offers 25 bar)

34 models defined in standard (Grundfos has 42 models in the ISO range)

Lower flow velocities

Stronger shafts / stiffer shafts

More space to build large shaft seals

14/25Technical features


15/25

NKG (ISO pumps), totally new concept on the

market for end-suction pumps - loose flanges

Loose flanges for 16, 25 or 40 bar rating.Stainless steel

Cast iron

DIN, JIS, ANSI

Loose flanges will only be available forstainless steel pumps.

Available in ductile cast iron and stainless

steel

The new rating will also be visible on thenew type designation.

The stainless steel pump housing in itself will

have a maximum pressure rating of 25 bar.


16/25

NKG, reinforced bearing design

Standard bearing design - with Greased-for-life bearings (17,500 h)

Heavy-duty bearing design - with automatic grease lubrication or oil lubrication (100,000 h)

We recommend to use theheavy-duty bearing

design when the inlet

pressure is above 10 bar


17/25

Bearing monitoringVibration and temperature

Vibration Monitoring =

shock pulse measuring

(SPM).

SPM-fittings are

standard on all heavy-

duty bearing designs.


18/25

Bearing monitoringVibration andtemperature

Sensors can be

factory- mounted - or

ordered as an

accessory.

Only available on

heavy-duty bearing

designs.
