Spare Parts Pumps Hayward

Questions and answers

How do I know which model of Hayward pump I have?

Check two places:

  • The pump housing or the pre-filter cover: Hayward —the model name is clearly printed there
  • The motornameplate: in addition to the model, it lists power in CV and kW, voltage, power supply (single-phase or three-phase), and the capacitor value in mF

Pay special attention to the “II”: Powerline and Powerline Plus II are different product lines, just like Starpump and Starpump II, or Super Pump and Super II. Ordering the parts list for the wrong version is the most common mistake with this brand.

Also note the power rating: the impeller, diffuser, and capacitor depend on it.

If the nameplate is worn away, send a photo of the entire pump, the pre-filter cover, and the nameplate via the contact form: the shape of the pre-filter and the pump body is usually enough to identify the model series.



Hayward Pool Pump Parts: Find Your Model

Hayward It’s one of the brands with the largest installed base in Spanish pools, and also one of the brands with the most model names: Super Pump, Super II, Max-Flo, Powerline, Powerline Plus II, Power-Flo II, RS II, Starpump, Starpump II, Tristar… Finding the right replacement part always starts with the same thing: identifying which model you have.

Here are the 10 product lines with their own exploded views, plus the decoder to help you tell them apart and the troubleshooting guide that resolves the four classic pump malfunctions: it won’t prime, it hums but won’t start, it leaks between the housing and the motor, or it stops on its own.

As an official E-Partner of Hayward, all replacement parts are genuine manufacturer parts with a warranty.

How to Identify Your Model Hayward

The model name appears in two places, so be sure to check both:

  1. Screen-printed on the pump body or on the pre-filter cover
  2. On the motornameplate, next to the powerrating in CV/kW, the voltage, and the capacitor value

One detail that determines many orders: the “II” is not just for decoration. Powerline and Powerline Plus II are different product lines, just like Starpump and Starpump II, or Super Pump and Super II. Their parts are not interchangeable, even though the units may look similar on the outside.

Is the nameplate illegible due to sun exposure or humidity in the pump house? This is common in older pumps. Send a photo of the entire pump, the pre-filter cover, and the nameplate via the contact form, and we’ll identify it based on its shape and pre-filter.

Anatomy of a Pump Hayward

They all share the same basic design, although part numbers vary by model series:

Prefilter (the part you touch the most)

  • Hair-collection basket: traps leaves and hair before they reach the fan. Replacement part #1—breaks if emptied too quickly or cracks in the sun
  • Transparent lid and its closure system
  • Lid O-ring: the cheapest part in the parts list and the number one cause of pumps that won’t prime. A worn O-ring lets air in even if not a single drop of water comes out

Hydraulic housing

  • Turbine (impeller): moves the water. It is replaced if the blades are broken or worn, causing a loss of flow
  • Diffuser: channels the water out of the turbine. It is paired with the turbine and the motor
  • Mechanical seal: the seal between the hydraulic assembly and the motor. If there’s a leak at this joint, it’s this part —and you shouldn’t leave it like that, because water will end up in the motor
  • Housing gaskets: Replace them whenever you open the pump
  • Drain plug: the one you open when winterizing the pump

Motor

  • Capacitor (single-phase motors): Provides starting torque. Always use the same value in mF
  • Thermal protector: cuts off the motor if it overheats and resets once it cools down
  • Fan and fan cover: for cooling. Without the cover, air does not circulate properly
  • Terminal box: provides the electrical connection

Quick diagnosis: from symptom to part

Symptom Most Likely Cause What to Check
Does not prime or loses prime Air entering through the prefilter cover O-ring on the cover; then the cover, seal, and connection joints
Bubbles inside the prefilter Air entering the suction line O-ring, liquid level, suction connections
It hums but won’t start Capacitor worn out Replace with a capacitor of the same value in mF; first, check that the shaft turns freely
Leaking between the housing and the motor Mechanical seal worn out Mechanical seal for your model
It stops and starts after a while Thermal protector tripped due to overheating Full basket, dirty filter, broken fan, unventilated enclosure
Loss of airflow even with a clean filter Worn impeller or damaged diffuser Impeller and diffuser rated for your power
"Gravel-like" noise (cavitation) Intake problem Basket, filter, pool water level, air intakes
Crack in the housing after winter Frozen water inside the pump body Pump housing
Leaves reaching the impeller Cracked strainer basket Hair-Catching Basket

 

Maintenance that extends the life of any Hayward

  • Empty the basket every week during the season. A full basket causes the motor to work against resistance—and is the indirect cause of half of all thermal protectors tripping
  • Lubricate the lid’s O-ring with silicone once or twice per season: it seals better, the lid opens smoothly, and the seal will last for years
  • Close the lid by hand, without tools
  • Open the drain plug when storing the machine for the winter. Frozen water inside the unit is the classic winter breakdown—and the most expensive of the preventable ones
  • Check the terminal box at the start of the season: moisture, rust, or a loose cover can lead to an electrical failure
  • Never run the pump without the fan cover in place
  • Before the first start-up of the season, with the pump disconnected, check that the shaft turns freely by hand

Can’t identify your model or find the part you need? Call us at 91 128 55 90 or contact us via the contact form with a photo of the entire pump, the pre-filter cover, and the nameplate. With these three pieces of information, we’ll identify the correct model range on the first try—even for older pumps. And remember this brand’s quirk: the “II” changes the part number, so check the name carefully before ordering.
