How to Select the Best Single-Speed Pool Pump for Your Pool

If you’re in the market for a reliable, cost-effective way to circulate your pool water, a single-speed pool pump might seem like the obvious choice. But not all single-speed pool pumps are created equal. Here’s what you need to know before you buy.

What is a single-speed pool pump?

A single-speed pump runs at one constant speed whenever it’s on. That means it’s either off or going full throttle, using the same amount of energy the entire time.

They’re simple, affordable upfront, and often the go-to for basic backyard pools. But with rising energy costs and growing demand for energy-efficient solutions, they’re not always the best long-term investment.

When a single-speed pump makes sense

Despite their limitations, single-speed pool pumps still make sense in a few situations:

• You’re on a tight budget and need a basic pump to get your pool running.
• Your pool is small or only used occasionally.
• You don’t have water features, solar heating, or complex plumbing.
• You don’t run your pump for long hours every day.

In these cases, a single-speed pump can be a decent, no-fuss option.

Key features to look for

Not all pumps are equal, even within the single-speed category. Look for:

• Motor size (HP): Common options include 0.5 HP, 0.75 HP and 1 HP. Match the horsepower to your pool size.
• Flow rate: Make sure the pump can handle your pool volume. Check litres per minute (LPM).
• Durability: Look for corrosion-resistant parts and a solid warranty.
• Noise levels: Some older or cheaper models can be loud. Go for pumps marketed as low-noise.

Match pump size to your pool size

Use this rough guide:

• Small pools (<30,000L): 0.5 to 0.75 HP.
• Medium pools (30,000L–60,000L): 0.75 to 1 HP.
• Large pools (60,000L+): 1.5 HP or consider a variable speed model instead.

Still unsure? Use your pool volume to calculate required flow rate, and match that to the pump’s spec sheet.

Pros and cons of single-speed pool pumps

Pros:

• Lower upfront cost.
• Simple to install and operate.
• Readily available replacement parts.

Cons:

• Higher electricity use over time.
• Not suitable for complex systems.
• Less control over flow rate and runtime.

Should you go single-speed or upgrade?

If you’re running your pump for long hours or want to reduce power bills, energy saving pool pumps (like variable speed models) are worth the higher upfront cost. Over time, they often pay for themselves.
