Grundfos Vertical Centrifugal CRN20-8-HQQE, Three Phase, 2″ Victaulic

Pumps for specific requirements
The CRN pumps can be customized to meet customer specific
requirements. This is due to the “mix-and-match”
approach to customization, where the many pump features
and options are to be regarded as modules that can be
combined to create the ideal pump.
Motor options
CRN motors are available in many different configurations to
meet the requirements presented by the power supply, the
pump environment and/or the pumped liquid itself.
• Power supply systems vary in terms of both frequency
and voltage, and required protection methods.
• The environment may be explosive, very hot and/or very
humid. Special conditions also apply at high altitudes.
• The pumped liquid can call for a special motor solution.
High or low viscosities and/or high or low densities may
require non-standard motor sizes. You may also need an
explosion-proof variant.
• The installation site of the pump may require alternative
positions of pump and motor parts, such as terminal box
positions and vent screw positions.
Shaft seal options
Extreme liquids sometimes call for extreme measures.
• High temperatures damage seal faces unless
precautions are taken.
• Concern for safety can necessitate special measures for
aggressive, toxic or flammable liquids.
• Liquids can be harmful to shaft seals because they
crystallize, harden or are extremely abrasive.
Pump options
The CRN pump elements can handle the most demanding
liquids and pressures, and be adapted to suit many other
requirements.
• Horizontal installation if height is a limitation.
Poor inlet conditions mean that NPSH values must be
adjusted to avoid cavitation.
• Very high pressures demand special solutions.
• Special surface treatments or certificates
