MER SERIES - MAGNETIC DRIVE PUMPS FOR ANY FLUID

MER series - Magnetic Driven Pumps are single stage, closed impeller type
centrifugal pumps. These pumps can be dismantled and assembled
without any special tools and rotating parts can be easily replaced,
hence bringing down the maintenance cost of the pump.
Chemical resistance:
The MER series pumps are designed for high chemical and
mechanical resistance. Thermoplastic materials such as GFR/PP
and PVDF suitable for temperatures range of -300C to +1200C
depending on the materials.
Non-plastic parts which are coming in contact with the pumping
media are in excellent corrosion resistance material such as
pure ceramic / silicon carbide and GFP/PP/CFT/PTFE.
Principle operation:
A group of magnets (drive) turns jointly with the motor shaft,
generating a magnetic torque that allows the rotation of
the second magnets (driven) group on which is moulded impeller.
A suitable shaped diaphgram separates the primary group of
magnets from the impeller and consequently from the pumped
fluid. This magnetic pumps are 100% leakproof, as they are
without mechanical seal & packing free.

Construction:
The volute casing is a single injection moulded with excellent chemical
resistant materials. Flanged connections are normally ANSI B16.5.
The rear cover realised with the same thermoplastic material is coupled with
volute casing forming tight chamber. 'O'-Ring in Viton or EPDM or FEP
guarantees a perfect sealing.
The shaft and the rotating parts are built of pure ceramic (AL2 O399.7%) or
silicon carbide.
The drive magnet as well as impeller magnet are made of isotropic and
anisotropic Ferrite or Neudimium - Iron - Boron depending on
the requirment.
Electric motor:
MER series pumps can be supplied with std. TEFC Non-FLP and FLP
motors.
Examples of applications:
The application’s field of this type of magnetic driven pumps includes a wide
range of possibilities.
Apart from the standard magnetic drive applications in the chemicals
industry, MER series could be successfully used in filtering plants water
treatment systems, heat exchangers, IC photoengravings, ultrasonic
cleaners, colours or black and processors and metal finishing industry.
Caution
• The pump must not run dry.
• These pumps are meant for clear fluid services only. Dirty fluids
(containing slurries or particles) may reduce durability of magnets resulting
into malfunction of the pump.
