Vertical Turbine Fire Pumps

Model – CR/CRI/CRN/CRT/CRE/CRIE/CRNE

Description:-

CR/CRI/CRN/CRT- Vertical, multistage centrifugal pump with inlet and outlet ports on the same level (inline). The pump head and base are in cast iron – all other wetted parts are in stainless steel. A cartridge shaft seal ensures high reliability, safe handling, and easy access and service. Power transmission is via a rigid split coupling. Pipe connection is via combined DIN-ANSI-JIS flanges. The pump is fitted with a 3-phase, fan-cooled asynchronous motor

CRE/CRIE/CRNE:- Vertical, multistage centrifugal pump with integrated frequency converter. The pump head and base are in cast iron – all other wetted parts are in stainless steel (EN 1.4301)

Applications:-

• Washing systems
• Cooling and air-conditioning systems
• Water supply systems
• Water treatment systems
• Fire fighting systems
• Industrial plants
• Boiler feed systems

Features and benefits:-

• Reliability
• High efficiency
• Service-friendly
• Space-saving
• Suitable for slightly aggressive liquids

Pumped liquids CR, CRI, and CRN pumps are suitable for pumping liquids that are thin, clean, non-flammable, non-combustible, or non-explosive liquids, not containing solid particles or fibres.

When pumping liquids with a density and/or viscosity higher than that of water, use motors with correspondingly higher outputs, if required.

Whether a pump is suitable for a particular liquid depends on a number of factors of which the most important are chloride content, pH value, temperature, and the content of chemicals and oils. Please consult Grundfos for information about which pump types are suitable for a specific liquid.

CR and CRI:- CR and CRI pumps are suitable for non-corrosive liquids. Use CR or CRI pumps for liquid transfer, circulation, and pressure boosting of cold or hot clean water.

CRN:- CRN pumps are suitable for industrial liquids. Use CRN pumps in systems where all parts in contact with the liquid must be made of high-grade stainless steel.

CRT for saline or chloride-containing liquids such as seawater or for oxidizing agents such as hypochlorites, we offer CRT pumps made of titanium.
