Mag-drive pumps from MSE enable seal-less, leak-free pumping
Seal-less, magnetic-drive pumps are available from Michael Smith Engineers for efficient, leak-free pumping.
The Viking Universal Mag Drive series of internal gear pumps comprises nine sizes of pump providing flows up to 114m³/hr. at pressures up to 14 bar.
An absence of a pump shaft seal means potential savings as a result of less maintenance and reduced downtime and with only two moving parts the simple design ensures durability and reliability even in tough applications.
The pumps are dimensionally interchangeable with Viking's Universal Seal and heavy duty bracketed pumps for easy retrofit with similar-sized sealed pumps, often utilising existing reducer, motor, coupling, guard, wiring and base, without the need for re-piping. The design also enables short-term dry-run capability and bi-directional operatio, without the need for modification or disassembly, allowing for filling or emptying using one pump to minimise costs.
Other features include dual thrust control washers to ensure positive control of rotor position for more accurate flow and reduction of pump wear, an externally adjustable relief valve which can be adjusted while in service when process conditions change.
Also, an adjustable rotor end clearance allows the pump to be adjusted for different viscosities and temperatures if process conditions change, ensuring high volumetric efficiency is maintained.
Available in cast iron, steel and stainless steel, these pumps provide are suitable for handling a range of liquids. For example, transferring hard to seal liquids such as isocyanates, sodium hydroxide, adhesives and epoxy resins, and also hazardous, reactive liquids such as volatile organic chemicals, LPG and ammonia.
Typical applications for Viking Universal Mag-Drive pumps include 24/7 operation in refineries, chemical, polymer plants and paper mills.
