CHI – Multi-Stage, Horizontal Pumps (316ss)
The Grundfos CHI is ideal for a wide variety of commercial and industrial applications. Its small size saves valuable space, while its rugged 316 stainless steel construction ensures a long, trouble-free life. The CHI features a maintenance-free, bellows-type shaft seal, so the pump can handle heavy-duty industrial liquids in a broad range of operating conditions.

FEATURES INCLUDE:
• All liquid-exposed parts are constructed of 316 stainless steel for maximum
astrength & reliability.
• Handles corrosive industrial liquids up to 230°F and develops up to 115 psi
a(275 feet of head).
• TEFC dual and tri-voltage motors available in 60 Hz (50Hz optional), UL
aapproved to U.S. and Canadian safety standards.
• Standard NPT connections simplify installation.
• Equipped with bellows-type shaft seals, sic/sic, carbon/TC, TC/TC, EPDM
aand FPM options.
• CHIE unit available, which is equipped with Grundfos MLE variable-frequency drive.

APPLICATIONS INCLUDE:
• DI Water
• Hot and Cold Liquids
• Oils
• Mild Acids
• Aromanic Hydrocarbons
• Potable Water
• Alkalis

CRI
Choosing the right pump can be difficult. It may be easy enough to find a pump that will do the job, but it gets trickier when you want an exact match. There are many good reasons to avoid over-capacity, with energy conservation at the top of the list. The CR range lets you choose pumps which exactly match your system demands.

WHAT CAN YOU PUMP?
Aggressive or corrosive liquids: Seawater, hypochloric acid, ferric chloride,
anitric acid, phosphoric acid.
Abrasive liquids: Metasilicate-containing cleaning agents, abrasive alkaline
acleaners, phosphates.
Toxic or explosive liquids: Trichlorethylene, toluene, petroleum, ethyl alcohol,
amethyl alcohol.
