A glandless pump is an ordinary centrifugal or turbine pump with no stuffing box or end seals. Dynamic sealing is replaced by static housing (shell) separating the flow-through part of the pump and the power-driven electric motor. The torque from the electric motor is transmitted to the pump shaft through the sealing shell by magnetic coupling (based on permanent magnets) consisting of the driving and driven half-couplings attached to the shaft of the electric motor and pump.
