Lined mag drive pump MNK 200-150-315

Product catalog summary

Overview: The document provides detailed information about Richter's sealless chemical magnetic drive pumps, specifically the MNK series, designed for handling corrosive, hazardous, and solids-laden media in various industries such as chemical, pharmaceutical, and water treatment.

Fields of Application: These pumps are suitable for chlorine electrolysis, large multi-purpose plants, H2SO4 concentration, MDI and TDI production, recycling plants, plastic and special fiber production, metal pickling solutions, and petrochemical plants.

Design Specifications: The MNK series features a single-stage, plastic-lined, magnetic drive chemical centrifugal pump with dimensions and performance data conforming to EN 22858/ISO 2858/ISO 5199 standards. It is a heavy-duty, horizontal, sealless design with an eddy-current-free, double "back pull-out" design.

Operating Range: The pumps can handle flow rates up to 600 m3/h, delivery heads up to 60 m LC, operating temperatures from -60 to 150 °C, and pressures up to 25 bar. They are designed for media where stainless steel and special cast iron are insufficient.

Materials and Construction: The pumps use virgin, unfilled lining plastics like PFA and PTFE, ensuring high resistance to permeation. The construction includes a closed PFA impeller, thick-walled PTFE housing lining, robust plain bearings, high-performance permanent magnets, and a double can system for enhanced safety and performance.

Service and Maintenance: The design includes a service-friendly "back pull-out" feature, integrated assembly aids, and options for rolling bearing lubrication. The lantern chamber can be monitored, which is advantageous for handling extremely hazardous media.

Performance Curves: The document includes performance curves for various models, indicating flow rates and delivery heads at different speeds.

Components and Materials: A detailed list of components and materials is provided, including housing, impeller, bearings, and magnet assemblies, highlighting the use of materials like ductile cast iron, PTFE, and stainless steel.

Dimensions and Weights: The document provides specific dimensions and weights for the MNK 200-150-315 model, emphasizing its robust construction and capacity.
