Description
Looking for a dependable pool pump? The Pentair IntelliFlo VS+SVRS 011057 combines proven Pentair engineering with the specifications you need to size it correctly. It features 2 in connections and is suited to in-ground pools.
IntelliFlo VS+SVRS is a permanent-magnet variable-speed pump with a built-in, non-defeatable Safety Vacuum Release System that shuts the pump off on drain blockage (VGB Act / ASME A112.19.17). In this guide we break down how pool pumps work, how to size one with simple turnover math, what to know about energy rules and electrical requirements, and how to keep your pump running quietly for years.
Quick Answer: What Is the Pentair IntelliFlo VS+SVRS 011057?
The Pentair IntelliFlo VS+SVRS 011057 is a variable speed pool pump running on 230V 1-Phase with 2 in plumbing connections. Variable-speed operation lets it run at low speed for daily filtration and ramp up only when you need more flow, which can sharply reduce energy use compared with a single-speed pump.

How a Pool Pump Works
A pool pump pulls water from the skimmers and main drain, passes it through a strainer basket that catches leaves and debris, and then pushes it through the filter, heater and sanitizer before returning it to the pool. Inside, an electric motor spins an impeller; the faster it spins, the more water it moves and the more pressure it can overcome.
That pressure is called total dynamic head (TDH). Every foot of pipe, every elbow, the filter and the heater add resistance. A typical residential pool plumbing system falls somewhere around 40 to 60 feet of head, which is why a pump's real-world flow is always lower than its open-flow maximum. Matching the pump to your plumbing, not just your pool size, is the key to quiet, efficient circulation.
Variable-speed pumps use a permanent-magnet motor and a built-in drive to run at any speed in their range. Under the pump affinity laws, cutting speed in half reduces power use to roughly one-eighth, so running longer at lower speed filters the water just as well while using far less electricity.
How to Size a Pool Pump
Pool pumps are sized by flow, measured in gallons per minute (GPM). The goal is to circulate, or turn over, the full volume of the pool in a set time. Many residential pools target one turnover every 8 hours; commercial pools often require 6 hours or less by code. The formula is simple: required GPM = pool gallons / (turnover hours x 60).
| Pool volume | 8-hour turnover | 6-hour turnover |
|---|---|---|
| 10,000 gal | 21 GPM | 28 GPM |
| 15,000 gal | 31 GPM | 42 GPM |
| 20,000 gal | 42 GPM | 56 GPM |
| 25,000 gal | 52 GPM | 69 GPM |
| 30,000 gal | 62 GPM | 83 GPM |
| 40,000 gal | 83 GPM | 111 GPM |
To estimate pool volume, multiply length x width x average depth in feet, then multiply by 7.5 for rectangular pools (or by about 5.9 for round pools using diameter x diameter x depth).
Then check the rest of the pad: the pump's flow should not exceed the maximum flow rating of your filter, heater or salt cell, and the pipe size should match the pump ports. Oversizing a pump wastes energy and can push water through the filter too fast. If you are replacing an existing pump, matching the horsepower and port size is a good starting point, and our team can help you confirm the right fit.
Good, Better, Best: Where the Pentair IntelliFlo VS+SVRS 011057 Fits
At HVAC365 we organize every category into a simple Good, Better, Best framework so you can compare options without wading through jargon. Within our pool pump lineup, this model sits in the Better tier: Enhanced comfort and smarter control.
The Better tier steps up efficiency and adds smarter control. It balances up-front cost with lower operating cost and more convenience, which is why property managers and owners who plan to keep their equipment for years often land here.
Not sure the Better tier is right for you? Compare it with the Good and Best options in the same category. Whatever tier you choose, the equipment is brand new and covered by the full manufacturer warranty, and our team is here to help you weigh features against budget.
Installation, Electrical and Energy Rules
Pool pumps should be installed on a level pad near the pool, below or close to water level when possible, with the correct pipe size on the suction and return sides. Electrical work must follow the manufacturer's instructions and the National Electrical Code, including GFCI protection and proper bonding. Professional installation by a licensed pool contractor or electrician is recommended. This model is rated for 230V 1-Phase and draws 16.0 A at 230V.
Since July 2021, U.S. Department of Energy efficiency standards for dedicated-purpose pool pumps have pushed most new residential in-ground filtration pumps toward variable-speed technology, and some states add their own rules. Many utilities also offer rebates for qualifying variable-speed pumps, so check with your local provider before you buy. DOE compliant: Yes.
Maintenance Tips
- Empty the strainer basket weekly, or more often during leaf season.
- Keep the lid O-ring clean and lightly lubricated with a silicone-based lubricant to prevent air leaks.
- Watch the filter pressure gauge; rising pressure means it is time to clean the filter, which also helps the pump.
- Listen for changes. Grinding or screeching can point to worn bearings, and bubbles in the basket usually mean an air leak on the suction side.
- Keep the motor dry, shaded and clear of debris, and make sure vents are not blocked.
- In freezing climates, drain the pump and plumbing or run freeze protection before winter.
Choosing a Pump for Your Climate
In the South and Sun Belt, including Florida, Texas, Arizona and Southern California, pools often run year-round and pumps log thousands of hours a year. That is where variable-speed savings add up fastest. Heat and heavy bather loads also demand steady circulation for sanitizer to work well. In northern states, the season is shorter, but pumps still need to handle spring openings, heater operation and freeze protection. Wherever you live, a pump that is sized correctly and programmed well is one of the best ways to cut the cost of owning a pool.

Frequently Asked Questions About the Pentair IntelliFlo VS+SVRS 011057
What size pool is the Pentair IntelliFlo VS+SVRS 011057 for?
Use the turnover table above and your plumbing size to confirm the fit, or ask us to check it for you.
Is a variable-speed pump worth it?
For most in-ground pools, yes. Running at lower speeds for longer can cut pump energy use dramatically, many pumps qualify for utility rebates, and federal efficiency rules now favor variable-speed models for most residential filtration pumps.
What voltage does this pump use?
230V 1-Phase. Have a licensed electrician confirm your circuit and breaker size.
Can I replace my old pump with this one?
Usually, if the port size, horsepower range and voltage are compatible with your pad. Send us the model number on your current pump's label and we will confirm.
How many hours a day should I run my pool pump?
Enough to achieve at least one full turnover per day, which for most residential pools means about 8 to 12 hours at low speed with a variable-speed pump. Hot weather and heavy use may call for more.
What warranty does it have?
It carries the full manufacturer warranty; warranty terms can depend on the installer and registration..
