Pumping/Drainage

Below are examples of pump equipment for pumping and drainage projects.

Reduced-noise underground drainage pumping station

1.Features

The noise is decreased by adopting the underground drainage pumping station and the influence on surrounding environment is lessened.

2. Main specifications

Horizontal-shaft semi-axial flow pump

• Pump bore: φ1,800 mm × 2 units
• Gas turbine output: 460 kW

Underground drainage pumping station with efficient use of ground space

1. Features

The aboveground section is efficiently used as public parking facility.

2. Main specifications

Horizontal-shaft semi-axial flow pump

• Pump bore: φ1,650 mm × 3 units
• Gas turbine output: 1,715 kW

Drainage pumping station combined with other facilities

1.Features

The drainage pumping station's space-conserving structure is combined with other facilities by stacking the other facilities on top of the drainage pumping station.

2. Main specifications

Large-capacity vertical-shaft semi-axial flow pump

• Pump bore: φ2,600 mm × 3 units “adjustable-blade pump: 1 unit”
• Diesel engine output: 820 kW

Pumping stations for high-capacity, long-distance pumping

1. Features

These pumping stations reduce noise by controlling noise and vibration for large-capacity, long-distance water supply.

2. Main specifications

Large-capacity horizontal-shaft double-suction volute pump

Water turbine drive pumping station

1. Features

This is a water pumping station with a hydraulic turbine that takes energy from moving water.

2. Main specifications

Pumping/drainage pump station

This is a pumping/drainage station with pumps that use hydraulic-type adjustable blades pump.

1. Features

The pump is used for supplying river water to water shortage area.
The discharge flow rate can be controlled by opening and closing the impeller blades.

2. Main specifications

Hydraulic-type adjustable-blade semi-axial flow pump

• Pump bore: φ3,500 mm × 4 units
• Electric motor output: 3,400 kW
