Light weight
Incorporating plenty of lightweight materials remarkably reduces weight to the minimum.
Employing a new development motor.
Our newly developed special motor suppresses the rotor tempera- ture rise to the minimum thereby completely preventing the motor from trouble such as burning due to overloading, the weak point of the ordinary single suction model. As a result, the new model’s service life has extended remarkably to more than three times that of our ordinary models.
Wear resistance is furthermore enhanced by selection of new material.
We carefully selected the special synthetic rubber as a new material for the pump section, including the casing, rear liner, and discharge cover. This selection dramatically reduces the risk of trouble when using water mixed with earth and sand or muddy water.
Easy maintenance.
To disassemble the impeller from the pump section, simply remove a few fixing bolts from the strainer. Additionally, we adopt the single suction structure in the same manner as before, eliminating the outer casing.
Vortex type Impeller.
Impeller is a vortex type thus saving the trouble of adjusting the impeller clearance. The new pump allows for smooth passing of foreign matter thereby almost always preclud- ing such trouble as a lock of pump operation due to clogging or blocking.
