High Capacity Lined Magnetic Drive Pumps MNK 200-150-315

Product catalog summary

Overview: The document provides detailed specifications and features of the Richter MNK 200-150-315 high-capacity lined magnetic drive pumps, designed for handling corrosive, hazardous, and solids-laden media in various industries.

Specifications: The MNK series pumps offer flow rates up to 600 m3/h and are capable of operating at temperatures ranging from -60 to 150 °C and pressures up to 16 bar. They feature a single-stage, plastic-lined, magnetic drive centrifugal pump design, conforming to EN 22858/ISO 2858/ISO 5199 standards.

Key Features:

SAFEGLIDE® PLUS: Provides dry-run capability to prevent damage.
PFA/PTFE Lining: Ensures full chemical resistance with a thick-walled virgin PTFE housing lining.
Low NPSHr Design: Optimized for processes requiring low Net Positive Suction Head.
High-Performance Magnets: Capable of handling torques up to 800 Nm.
Double Can System: Features a modified PTFE wetted can and a carbon-fiber reinforced plastic pressure-bearing can.

Applications: Suitable for use in chemical and pharmaceutical industries, water treatment, pulp production, metal processing, and waste disposal. Specific applications include chlorine electrolysis, handling of H2SO4, HCl, NaOH, NaOCl, and production of MDI, TDI, plastics, and special fibers.

Design and Materials: The pump is constructed with ductile cast iron, PTFE, and other robust materials to ensure durability and resistance to corrosion. It includes components like a closed PFA impeller, robust plain bearings, and a stable metal core with a seamless thermoplastic PFA lining.

Service and Maintenance: The design includes features for easy maintenance, such as a double "back pull-out" design, integrated assembly aids, and options for ball bearing lubrication.

Performance Data: The pump's performance is illustrated with graphs showing flow rates and head capacities at various RPMs, highlighting its efficiency and capability in different operational scenarios.
