Water Pump HITACHI WM Series

Water Pump HITACHI WM SERIES

HITACHI PUMP WM SERIES (Shallow water suction)

Inverter

• The inverter system commands the motor to adjust its operating speed to maintain a constant and steady water pressure at every point.
• With a motor-driven direct current system and a specially designed pump housing, the water pump operates more efficiently, delivering a water flow that is 20% greater than conventional pumps.
• The pressure tank is charged with nitrogen gas and reinforced with a diaphragm made of neoprene, ensuring that the water does not come into direct contact with the tank. This prevents corrosion throughout the lifespan of the system.
• This design eliminates rusting over the course of its operational life.
• Energy savings of up to 40% are achieved.
• Installation requires less space compared to traditional systems.

Constant pressure automatic water pump 

• Automatic switches operate in rhythm with the opening and closing of the water faucet.
• The pressure tank is composed of diaphragm rubber sheets, equipped with nitrogen gas.
• It provides a steady pressure, addressing corrosion issues throughout its operational lifespan.
• The Water Temp Relay helps prevent abnormal operation when the temperature exceeds normal levels.
• Prevention of deformation of other components.
