NRPG Horizontal Self-Priming Side Channel Pumps

NRPG Horizontal Self-Priming Side Channel Pumps The NRPG is part of the North Ridge S Series - a selection of Self Priming side channel pumps that are designed for the handling of volatile clean liquids containing up to 50% entrained gas. Constructed for the handling of liquid-gas mixtures, it has been specifically built to handle fluids which may be transferred at high pressures or low temperatures (refrigerants) which are close to their boiling point. Example fluids handled include chemicals, fuels, refrigerants, and clean fluids which are transferred at low flows and high pressures including fresh water or seawater. The S series has been developed with the purpose of handling liquids under vapour pressure or when pumping from underground tanks. An inbuilt inducer allows the pump to operate with an NPSH as low as 0.5M meaning it is able to completely drain tanks, handle liquids close to their boiling point, and transfer liquids in tanks with low levels without cavitating. The NRSC pumps have a retaining stage to avoid dry running. Built as a side channel design, it allows for efficient operation, with easy maintenance providing long lasting reliability. The NRSC is modified to suit operator's needs, utilising a variety of differing materials, stages, and sizes to match the duty point required. The North Ridge S Series Design Features • High Self Priming Capability - Up to 7.4M• Extremely low NPSH <0.5M or Less• Handle volatile liquids with up to 50% entrained gas• ATEX Certified• Eliminates the requirement for expensive infrastructure when handling liquid gases.• Modular design reduces spare part holding and enables pumps to be scaled according to process needs• Variety of Sealing Options Product Summary • Side channel design• Designed to handle liquids, gases, and liquid-gas mixtures with up to 50% vapor• Low NPSH Requirement typically 0.5M• Self-priming up to 7.4M• High pressure at low capacity
