Long Service Life with Standard MotorPump with thrust bearing without additional axial loads on the motorbearings.Any standard motor V1 design (suitable to be lifted in vertical posi-tion) can be used, of our choice or of Clientʼs choice.
Easy Assembly of the MotorWith the single-piece sleeve coupling the pump unit can be suppliedfully assembled also without the motor. This eliminates the risk ofdamage caused by shifting of the pump shaft during transportation.The motor is simply inserted in the coupling and fastened to theflange without the necessity for adapting the axial position of thepump shaft.
Extra SafetySingle-piece coupling guard to be removed only by means of a tool,positioned around the lantern bracket, thus avoiding accidentalpushing and rubbing against the coupling.
Low Cost InstallationVertical construction with reduced pump height for installation insmall spaces. In-line connections to simplify the piping layout with the possibilityof inserting the pump in straight pipe-lines. Disassembly, inspection or cleaning of internal parts withoutremoval of piping.
Robust and ReliableSingle PN 25 construction for all pump sizes.The suction and discharge nozzles arranged in-line absorb the forcesof the piping on the pump without the creation of distorting loads caus-ing local friction and early wears.The lantern brackets compact and robust design maintains a surealignment between rotating and fixed parts, reducing vibration.The upper cover design prevents entrapment of air around themechanical seal.
Low-Noise OperationThe water filled shroud around the stages and thick external walls,work together for low-noise operation.Low-noise standard motor.
