 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
