Submersible Motor Pumps for Hot Spring Deep Well

The major merit uing submerge motor pump

In comparison with the conventional type of hot spring water pumping.

  • To avoid scale (fur) left inside water pipes and containers.
  • To maintain the hot spring water temperature longer.
  • To achieve more efficiency during water drawing.
  • To assure more constant and continuous flow (water discharge) eliminating pulsation.
  • Less noise and friction/vibration.
  • Automated operation possible.
  • Pump housing unnecessary.
Remakable features of our motor pump for deep well
  • 1. To cope with a maximum temperature of 90 ℃.
  • 2. Max. Head 700m (2,2797ft)
  • 3. To be applied to the well water containing a lot of gas inside, by utilizing the special model provided with gas separator, thus preventing gas lock.
  • 4. Availability of a wide variety of pumps and rich stock meet with the customer’s short delivery request.
  • 5. Custom-made pumps possible based on the customer’s need such as hot spring water quality.

1. Above-ground components

・Discharge frame
・Air vent valve
・Compound gauge with cock
・Check valve
・Sluice valve
The standard material used for the pump components on the ground are made of stainless steel cast, suitable for special hot spring water quality.

2. Riser Pipe

Pipe materials can be selected depending on the well water characteristic, and available materials are of FRP, cast iron, cast iron lined with plastic, or stainless steel.

3. Power Cable

Heat resistance cable can be selected from the list, depending on the water temperature and cable length.

4. Cable clip

To be selected from either by electrode type or by pressure sensor type.

5. Control Panel

Types of panels can be selected depending on the site conditions and customer’s demand from either of indoor or outdoor wall-to-wall mounted type, or self-standing indoor type.

6. Transformer

In case the cable length is too long due to the deeper pump installation, it is recommended that a transformer to be provided to utilize the higher voltage, thus shortening the total cable length.

7. Submersible motor pump

The most appropriate motor shall be selected, after studying and calculating the various conditions like but not limited to hot spring characteristic, well diameter, existence of gas in the hot spring water, highest hot water temperature, the maximum depth of well water.
