High-Flow Centrifugal Pumps for Greenhouse Irrigation: A Practical Case Study on Energy Efficiency with the S2DK Pump

An Efficient irrigation is critical for modern greenhouse agriculture. When water demand increases across large planting areas, pump selection becomes a key factor in system reliability and operating cost.

In this project, our customer required a stable, high-flow water supply to irrigate an entire vegetable greenhouse using a centralized system. After evaluating the site conditions and irrigation layout, a solution based on two high-flow centrifugal pumps was selected.

Application Background

The project is a large vegetable greenhouse used for continuous crop cultivation.

Key requirements included:

• High water flow to cover the full greenhouse area

• Stable pressure for uniform irrigation

• Long operating hours during peak growing seasons

• Simple system design with easy maintenance

Pump Solution Overview

To meet these requirements, the system was designed with two high-flow centrifugal pumps working in parallel.

This configuration allows:

• Sufficient total flow to supply the entire greenhouse

• Flexible operation (one pump or two pumps depending on demand)

• Improved reliability and system redundancy

Centrifugal pumps were chosen for their strong continuous-duty performance and efficiency in clean water irrigation applications. 

Why High-Flow Centrifugal Pumps?

In greenhouse irrigation, flow rate is often more critical than high pressure. The selected pumps provide:

• Large flow capacity for wide irrigation coverage

• Stable hydraulic performance for uniform water distribution

• Energy-efficient operation during long running periods

• Simple structure, ideal for agricultural environments

Results & Customer Benefits

With this solution, the customer achieved:

• Reliable irrigation for the entire vegetable greenhouse

• Consistent water supply during peak irrigation cycles

• Reduced downtime thanks to dual-pump configuration

• Easy system expansion for future greenhouse growth

How We Went the Extra Mile

At Stream Pumps, we pride ourselves on flexibility and customer-focused innovation. In this project, the customer requested a replacement pump with higher flow and head than our existing range.

Instead of a standard off-the-shelf solution, we:

• Carefully analyzed market demand and future competitiveness of the pump

• Redesigned and improved our S2DK pump series

• Expanded the performance range from 1.5HP to 3HP to meet and exceed the customer's requirements.

This is a great example of how we adapt our products based on real customer needs while enhancing our overall product line for the wider market.
