Construction


Pumping and power solutions designed for job site mobility, drainage, and infrastructure projects — durable, portable, and efficient.

Reliable Pumps for Construction Projects – Why Choose Koshin and JS Pumps

In modern construction projects, efficient water management is essential. Whether it’s dewatering excavations, removing floodwater, or handling sludge and slurry, the right pump ensures safety, efficiency, and cost savings on site. Two brands stand out for their durability and performance: Koshin and JS Pumps. Both are trusted worldwide and offer specialized models designed for the toughest construction needs.

Why Pumps Are Vital in Construction

Construction sites often face water-related challenges:

  • Groundwater seepage into foundations or trenches

  • Rainwater accumulation delaying work

  • Muddy and abrasive water with sand and debris

  • Temporary sewage and wastewater handling

Without proper construction dewatering pumps, projects risk delays, higher costs, and safety hazards. That’s why professional contractors rely on engine-driven pumps for portability and submersible electric pumps for continuous duty.

Koshin Pumps for Construction

Koshin, a Japanese manufacturer, is renowned for its engine-powered trash and semi-trash pumps. These models are ideal for construction sites where power supply is limited or mobility is required.




Recommended Koshin Models:
  • Koshin KTZ-80S Trash Pump Heavy-duty engine pump with high flow capacity, designed to handle muddy water mixed with stones and debris. Perfect for fast dewatering of trenches and pits.




  • Koshin KTH-100X High Volume Trash Pump Delivers strong pumping power with solids handling capability – suitable for large-scale construction and civil engineering projects.




  • Koshin SEH-80X Clear Water Pump A reliable choice for pumping clean or slightly dirty water from flooded areas, rainwater ponds, or site cleaning.

Choosing the Right Pump for Your Site

For best results, construction companies often use a combination of Koshin and JS Pumps:

  • Koshin Trash Pumps for portable, engine-powered dewatering in areas without electricity

  • JS Submersible Pumps for permanent or semi-permanent installation where continuous pumping is required

This combination ensures flexibility, efficiency, and reliability across all phases of construction.


Investing in high-quality construction pumps reduces downtime, increases productivity, and ensures safety on site. Koshin offers portable, engine-driven pumps ideal for off-grid or fast deployment, while JS Pumps provide robust electric submersible solutions for drainage, sewage, and slurry handling. Together, they deliver the reliability every construction project needs.
