Pump considerations for upcoming infrastructure projects

By: Tsurumi

The $1.2 trillion infrastructure bill signed into law in November will bring substantial new investments in infrastructure across the country. Most of the bill is dedicated to projects that will involve engineering and construction, and pump manufacturers are poised to see a significant increase in demand for products and support services.

With Infrastructure Week (May 16-20) in focus, Tsurumi Pump Regional Sales Managers Derek Jackson highlights the pump qualities contractors should pay the most attention to for infrastructure work.

What role do pumps play in infrastructure projects?

Jackson: Pumps play an essential two-part role in infrastructure. First, in the process of creating infrastructure, they keep construction sites dry. Second, once work is complete, they’re often in place to support operations. Dewatering is an indispensable part of many infrastructure projects even before they begin. For example, when building a bridge, even the early stages of developing the foundations and access ramps will require builders to deal with groundwater. They then need to be prepared to handle rainwater and other surface water during the project. Or if you consider tunnels and other excavation pits, it’s crucial to keep water out of ongoing construction. Pumps might be used to provide water for jetting and sluicing in these applications. In terms of operations, once a structure is complete, pumps will often be used for moving wastewater and stormwater and keeping surfaces dry. At any time, water can become a serious issue if not dealt with effectively.

What design features are most beneficial to project engineers and contractors?

Jackson: Contractors prefer using pumps that are durable and robust. A dependable design is key. Electric submersible pumps offer several advantages over engine pumps, such as easy operation and low maintenance. Pumps typically encounter tough conditions at job sites and if they cannot sustain the day-to-day demands, they can bring an entire project to a halt. Pumps should be mobile to provide flexibility on the job site because getting water out of the hole or surface will take priority during a construction schedule. For infrastructure projects, pumps should also be designed to handle slurries and abrasive particles. Having a pump made of wear-resistant materials with dry run capabilities and a wide operating area is ideal for a project’s success. Often contractors can face financial penalties if projects go beyond the expected completion date, so it’s crucial to have the most dependable equipment at hand.

 

Tsurumi pump considerations for upcoming infrastructure projects (1)What qualities of pumps help them stand up to infrastructure work?

Jackson: Established manufacturers like Tsurumi have taken the belt-and-suspenders approach to the range of submersible pumps we manufacture. Tsurumi standardizes many features that increase durability, making our pumps some of the most dependable in the world. These include anti-wicking cable entries to prevent motor failure if a cable is cut or nicked on the job site; dual internal silicon carbide seals with an oil bath and oil lifter, which allow for dry run capability; large shafts and oversized bearings for a wider operating range across the pump curve; thermal protection; and (on many pumps) high-chrome wear parts to resist abrasive wear.

What are some of the advantages of using electric pumps in construction work?

Jackson: Electric pumps are quieter than engine-driven pumps and do not have issues with refueling and potential fuel spills. In addition, engine pumps require an oil change every 200 hours of operation, unlike submersible electric pumps. Plus, there are no emissions. If electricity is available, the cost to run an electric pump is lower than a diesel-driven alternative. An electric unit will work continuously without failure when plugged into a stable power supply. In addition, electric power is cheaper than fuel, and maintenance costs are lower.
