 Leakproof,
Seal-less Construction
No shaft seal is used or required on these magnetically driven pumps.
Power is transmitted by a magnetic field traveling from a magnet
attached to the motor, through the solid body of the pump, to a
magnet attached to the impeller. No shaft seal ensures that leakage
and troublesome seal replacement are completely eliminated. The
superior seal-less, magnetic drive design provides a reliable, smooth
running, vibration-free pump that delivers high flow and pressure.
Excellent
Chemical Resistance
The wetted components of these rugged seal-less pumps are available
in your choice of Polypropylene or all PVDF. Polypropylene is glass
reinforced and PVDF is carbon reinforced for
added strength and reliability. These materials offer broad corrosion
resistance to acids, alkalies,
caustics, bleaches, sea water, solvents and many harsh environments.
All pumps include a 99.5% Alumina ceramic shaft and thrust washers.
High purity carbon bearings are standard with Ryton® or silicone
carbide available where required. Viton o-rings are standard on
all pumps, while teflon and EPDM are available. There is no metal
contact with the liquid being pumped.
Run
Dry Capability
Once a Sethco end suction pump has been primed with solution, it
is possible for it to run dry without damage if flow to the pump
is interrupted for any reason. Run dry times may vary depending
on model, bearing type and piping configuration.
Designed
for Reliability
Among its many features is its unique impeller/driven magnet design.
The two are separate distinct pieces so that one can be replaced
without having to purchase the other. This feature also reduces
the load on the front bearing and trust washer.
Easy
to Maintain
In the event a pump should ever need service, the limited number
of parts allows for easy disassembly, inspection and maintenance
without any special tools or talent. The motor can be separated
from the pump housing without difficulty. Magnetic coupling design
acts as a clutch to eliminate motor burnout and overloading under
adverse conditions. Magnet housing acts as an insulator to prevent
motor heat from being transferred to the fluid being pumped |
