Japanese Standard Quality
Having almost 100 years of water pump manufacturing experience, these exceptional pumps are designed to deliver high performance and reliability.

Environment-Friendly Design
Every unit is certified with the stringent RoHS standard, as well as ISO 9001 for factory quality management, and ISO 14001 for environmental management.


Reliable, Long-Lasting Safety

Specially designed for durability, longer service life, and safety.

Reliable, Advanced Motor
Hitachi’s motors are widely regarded for their high performance and long-lasting durability.

Rust-Resistant Bolts
The stainless bolts are rust-resistant and contribute to ease of maintenance throughout the pump’s service life.

Thermal Relay
The thermal relay is an essential mechanism inside Hitachi motors. It automatically disengages the motor when the temperature rises above the preset level and re-engages it when it is safe.

Rust-Resistant Check Valves
Copper alloy check valves installed in water pumps are machined from a special alloy so you can rest assured that they will be rust-resistant and contribute to the overall durability of your water pump.

Water Temp Relay
The water temp relay temporarily pauses operation when it becomes too hot. This prevents the deformation of parts due to overheating.

Ventilation Fan
Hitachi’s specially designed vent fan works wonders in ventilating heat to ensure more effective operation and thereby prolong the motor’s life.

Heat-Resistant Rubber Seals
Seals are made of heat-resistant materials. They are less likely to fracture so you will not be troubled by water leakage.

Specially Designed Pump Head
The single-piece, seamless, molded pump head made from special plastic and first-grade materials frees you from worries of rust and leakage while giving you superior water output.

Specially Designed Pump Cover
The pump cover has been newly designed to comply with the stringent IEC safety standard. The cover fits snugly on the body, enhancing safety during operation. A heat ventilation duct at the back also helps the unit to work more effectively.


Constant Water Pressure

Life-Extending Pressure-Stabilized Unit
This unit controls the flow of water to maximize pressure switch life and the pump’s service life, ensuring continuously stable water pressure. The result is that you will no longer be troubled by irregular or intermittent water supply.

Bladder Tank
It is lined with a diaphragm of rubber sheets and filled with nitrogen. These advanced Hitachi technologies ensure stable water pressure and convenience since there is no need to refill the gas or worry about rust throughout the tank’s service life.


Big Water Capacity

Increased by up to max. 22%
Pumping discharge is increased up to 22% compared with conventional models. Even if your place has many water taps, you can always enjoy ample water flow.


Quiet Operation

Reduced by up to max. 10dB
The new XS series achieved both powerful water flow and quiet operation by reducing the metallic sound when the pump is in process. Even in the areas where the houses are close together, it’s unlikely to cause annoyance and you can enjoy a late-night shower without worry of disturbing the neighbors.
