LN, LP SERIES

Product catalog summary

Introduction
The Lubi LN and LP series are corrosion-resistant thermoplastic pumps designed for continuous medium pressure circulation or transfer of non-flammable liquids compatible with the pump materials. They feature a water seal flush port for decontamination and a rotatable discharge. These pumps handle specific gravities up to 1.1 and are available in power ranges from 0.37 to 2.20 kW for both single and three-phase power supplies. Constructed from Noryl or Polypropylene, they are available as close-coupled or long-coupled with standard or flame-proof motors.

Specifications

Flow range: Up to 22.5 m³/h
Head range: Up to 22 metres
Ambient temperature: Max. +50°C
Liquid temperature range: 0°C to +82°C (Noryl), 0°C to +60°C (Polypropylene)

Materials
Noryl pumps are designed for industrial chemical applications, offering resistance to most acids, alkalis, and inorganic solvents. Polypropylene pumps are suited for light industrial or commercial water-based applications, also providing chemical resistance.

Features and Benefits

Compact design and easy installation
Quiet operation and robust construction
Back pull-out design for easy maintenance
Dynamically balanced rotating parts for vibration-free performance

Operating Conditions
The pumps are suitable for non-flammable, corrosive, aggressive, and hazardous liquids compatible with the pump materials.
