MEK

Product catalog summary

Overview: The document is a technical catalog for the SANWA MEK series metallic self-priming magnet drive pumps, designed for extensive hydraulic performance, seal-less operation, corrosion resistance, and leak-free applications. These pumps are suitable for chemical processes, laboratory use, food and pharmaceutical manufacturing, and more.

Specifications: The MEK series pumps feature a motor output range from 0.25 kW to 4.0 kW. They are constructed with SUS 316 stainless steel for high chemical resistance and include SiC-D bearings for increased damage prevention and reduced friction. The pumps are designed to handle organic solvents and other chemicals without leakage.

Applications: The pumps are applicable in various industries, including chemical processes, water purification, desalination, food and beverage production, ultrasonic cleaning, and medical equipment.

Construction and Materials: Key components include a magnet coupling, pressure vessel, rotating parts, bearings, and liquid-immersed portions. The use of SiC-D bearings allows for dry run tolerance and extended service life due to their low friction coefficient.

Performance and Selection: The document provides performance charts indicating total head and capacity for different pump models (MEK201, MEK251, MEK322, MEK402) and outlines the specifications for each model, including applicable temperature ranges, design pressure, and maximum viscosity.

Dry Running Protector: An optional DRN series dry running protector is available, which uses electric current sensing to stop the pump in case of dry running or air intake, preventing damage from overload.

Magnet Drive PumpslMEK : Magnet : Pressure vessel : Rotating parts : Bearings : Liquid immersed portion Significance of SiC-D - Increased damage prevention - » SiC-D bearings can withstand accidental dry run for certain periods. » Unique materials and manufacturing techniques of our specially treated SiC-D bearings provide a coefficient of friction 1/4 that of SiC. » The very low coefficient of friction of our SiC-D bearings results in much less heat being generated in upset or dry running conditions. SiC-D bearings are more forgiving of dry running conditions frequently encountered at start...
