Diesel vs Electric: Which is better for pump systems? (Part 2)

Diesel is often the preferred energy for pump systems, particularly temporary sites. But electrical pumps can be a superior alternative. This is part two of a two-part article.

Electric pumps’ lower maintenance and service requirements also offset many of diesel’s hidden costs, and the added advantages of lower carbon generation and quieter pumping conditions add to the case for using electric pumps.

Yet, they are not suited for all conditions. Notably, you need electricity to run such pumps, which can mean more outlay at the start to establish an electrical feed on a site if one isn’t available. Solar systems address this problem, but they also have upfront infrastructure needs. Still, under most conditions – and especially for rental or sites that aim to evolve from temporary to permanent pumping systems – there is a strong case to consider electric pumps.

 

Making the best choice

Diesel pumps are not on their way out. Diesel systems have earned a reputation for resilience in harsh conditions, and diesel pumps are better suited for some conditions, such as pumping fluids with many heavy and large solids. They are also the preferred choice for remote and rural sites where access to electricity supply is unavailable or expensive. In very short-term scenarios, diesel’s performance can give it the edge over electric systems. Diesel’s portability also facilitates easy deployment, whereas electric systems are more likely to suit permanent installations.

Diesel’s drawbacks are also not new. Noise and emissions (especially in enclosed spaces) have been issues for decades yet have not diminished the popularity of diesel pumps. Electric pump systems are not replacements for diesel but provide alternatives where diesel’s drawbacks create problems for a site.

“The best choice between diesel and electric pumps will depend on your scenario,” says Mistry. “What has changed is that diesel is no longer the only serious contender, even for temporary sites and rental plans. And as fuel prices rise while renewable energy brings down the cost of electricity, there is good reason to consider electric pumps instead of diesel pumps, rather than just assume diesel is by default the best choice.”

Don’t just bet on diesel when deciding to rent or purchase pumps for your next project. Consider your options and select the best choice for overall value.
