Feature

Parts required strength is made from highly stiff precision stainless cast steel.
By mainly adopting stainless steel, resin, rubber, and bronze make it free from red water generation.
Starting with the adoption of a low noise type TEFC motor, the flow of the water inside the pump is also ideal and the driving noise is quiet.
Provided companion stainless flange as standard accessory, make it easy for installation.
Easy maintenance and inspection without disconnection of pipe due to back pull out construction.
Adopting Stainless cast steel for casing, and Bronze for Guide vane and Impeller, prevents red discolored water arising form portion contacting liquid.
Compact & high head type multistage pump for 2 poles motor.
High efficiency design balances less number of stages and high head.
Compact design brings less installation space & trimming weight.
Long life mechanical seal is adopted for shaft sealing.
Adopting closed ball bearing for bearing can omit oil filling and makes inspection and replacement easy (Patent).
Other suction direction is also available
Base has hard to accumulate condensation water shape (PAT). Evaluated item of "Horizontal centrifugal pump" by (C) Public Buildings Association., Ltd. in Japan.
