A Mechline pump is a triple screw pump with a mechanical seal inside. A mechanical seal is a simple method of containing lubricating fluid within the triple screw pump. A mechanical seal maintains the pressure of the lubricating liquid being pumped, using sealing gaskets and O-rings to complete the seal, and withstand any friction caused by the rotor turning.
In Mechline mechanically sealed pumps, a micro-gap is created within the seal to allow a leak path. The seal faces cannot be permitted to run dry as the frictional heat build-up will very quickly cause severe seal face damage and extensive leakage. All mechanical seals must leak to operate properly. This makes it impossible for a mechanical seal to be leak-free. The amount and visibility of the leakage will vary from pump to pump.
Mechline (mechanically sealed) triple screw pumps are typically lower-cost seals. They are an effective choice for creating a seal within the triple screw pump. By fitting a mechanical seal to your triple screw pump that is the optimum design size and material, you can extend the lifespan and productivity of your machinery/applications.
Magnaline and Mechline pump both have their advantages; it depends upon the environment and customer requirements. Our team can advise which pump type best suits your needs and can quote you both the Mechline and Magnaline alternatives.
