Grundfos Inline Multi Stage Pumps
Trust the CRN for corrosion-resistant reliability
The CRN pump is an in-line, multi-stage pump available in a wide variety of flow and pressure sizes. Built from high-grade AISI 316 stainless steel, the CRN is perfect for ultra-filtration, reverse osmosis, machine tools (cooling lubricants), distillation systems, swimming baths, oils, alcohols, acids and alkalis, process-water systems and processes handling a broad range of problematic liquids.
Applications:
- Commercial air conditioning
- Irrigation
- Industrial heating
- Industrial water supply & transfer
Grundfos CRN Pump Set Series
A number of ATEX-approved CRN pumps are available, according to the locality, hazard and likelihood of a dangerous situation occurring. ATEX-approved pumps are for use in potentially explosive atmospheres. Explosive atmospheres consist of air and combustible matter such as gases, vapours, mist or dusts in which the explosion spreads after ignition.
DIFFICULT LIQUIDS & SITUATIONS
Available in customised high grade AISI 316 stainless steel versions for difficult operating conditions, such as maritime applications and very humid environments.
TEMPERATURE RESISTENT
Available with air-cooled top with a special air-cooled shaft seal chamber, enabling it to handle liquid temperatures up to 180 °C at maximum 25 bar
EFFICIENT SOLUTION
Minimised pressure loss with lower NPSHr improves hydraulic efficiency, overall pump performance and allows for a compact, space-saving system design.
HIGH HYDRAULIC EFFICIENCY
Performance is optimised from fluid mechanics insights provided by extensive simulation-driven design and verification.
