💫 Laing E10 Fixed Speed Circulation Pump – 65W – 3/4″ Smooth Barb
Ultra-quiet, energy-efficient circulation with seal-less spherical motor technology
📋 Product Overview
The Laing E10 Fixed Speed Pump with ¾-inch smooth barb connections is a compact 65W circulation pump designed for continuous operation in spas and hot tubs, providing efficient water flow with exceptionally low energy consumption. Operating at 230V/50Hz and drawing just 0.7A, this pump is engineered for economical 24/7 operation.
The Laing E10 utilises an innovative permanent magnet motor design that allows 90% of motor heat to be transferred into the water, keeping the pump running cooler. The shaftless, seal-less construction eliminates the most common failure points found in traditional circulation pumps, delivering exceptional reliability over the pump’s lifetime. The clog-resistant open impeller is dynamically balanced with a carbon bearing for smooth, ultra-quiet operation.
Operating at 3,200-3,500 RPM within an ultra-compact body (152mm × 110mm × 124mm), this pump delivers a maximum flow of 10 GPM with a maximum head of 6.5 metres. The new E10 uses 40% less energy and runs 40% cooler than previous red-bodied models, and includes a smart chip that gradually increases RPM at power-up to ensure air-lock free startups. The thermoplastic motor bracket is adjustable to four different discharge angles, providing flexible installation options. Built-in dry run protection helps prevent damage if the pump is accidentally run without water. Commonly found in Sundance, Jacuzzi, Hot Spring (replacement for Silent Flo 5000), Artesian, Caldera, Dimension One, LA Spa, Iberspa, Island Spas, Saratoga, Canadian Spa, Spa in a Box, and Spring Spa hot tubs.

The hot tub industry doesnt make it easy for you when you are trying to match up the size of the unions (the part that screws your pipe work onto the pumps) Below you can see the physical sizes of the collars, and how they relate to the actual union size you need. So a measurement of 2.5", edge to edge on the collar of the pump is actually a 1.5" union - confusing - absolutely! If you are not sure, give me a shout!

Important Notes
How do I Replace a Hot Tub Pump?
Here's a general step-by-step guide on how to replace a hot tub pump. Keep in mind that the specific steps may vary depending on your hot tub's make and model, so it's essential to consult your hot tub's manual for model-specific instructions. If you're not comfortable with this procedure, it's a good idea to seek professional assistance.
Materials You'll Need:
- Replacement pump
- Pipe wrench
- Adjustable wrench
- Screwdriver
- Pipe sealant (thread tape or plumber's putty)
- PVC primer and cement (if you have PVC plumbing)
- Teflon tape (for threaded connections)
Procedure:
- Turn Off the Power: Before you begin, ensure the hot tub's power supply is turned off at the circuit breaker or disconnect switch. Safety should always be a priority when working with electrical components.
- Drain the Hot Tub: If your hot tub is not already empty, you'll need to drain it. Follow your hot tub's manual or manufacturer's instructions for proper draining. (You might not need to do this if you can lock the pump off with the gate valves)
- Locate the Pump: Identify the location of the existing pump in your hot tub. It's usually located near the equipment area or in a designated pump compartment.
- Disconnect the Electrical Wiring: Carefully disconnect the electrical wiring from the old pump. This typically involves removing the electrical conduit cover, unscrewing wire nuts, and disconnecting the wires from the terminals. Be sure to note the wire connections or take a picture for reference when connecting the new pump.
- Disconnect the Plumbing: Depending on your hot tub's plumbing setup, you'll need to disconnect the plumbing connections to the pump. Use a pipe wrench or adjustable wrench to loosen and remove the fittings. Be prepared for some water spillage when disconnecting the plumbing.
- Remove the Old Pump: Once the electrical and plumbing connections are detached, carefully remove the old pump from its mounting position. Some pumps may be secured with mounting brackets or bolts.
- Prepare the New Pump: If the new pump is not pre-assembled, you may need to attach fittings, unions, or adapters to match your hot tub's plumbing. Ensure that you use the appropriate sealant or Teflon tape on threaded connections to prevent leaks.
- Mount the New Pump: Position the new pump in the same location as the old one and secure it in place using the mounting brackets or bolts.
- Reconnect Plumbing: Reconnect the plumbing to the new pump, ensuring that all connections are tight and secure. If your hot tub uses PVC plumbing, use PVC primer and cement to bond the connections properly.
- Reconnect Electrical Wiring: Reconnect the electrical wiring to the new pump, following the notes or pictures you took earlier. Make sure all wires are properly connected and secure.
- Turn On the Power: Restore power to the hot tub by switching on the circuit breaker or reconnecting the disconnect switch.
- Test the Pump: Turn on the hot tub's pump to ensure that it's working correctly. Check for any signs of leaks or irregularities in the plumbing connections.
- Refill the Hot Tub: Once you've confirmed that the new pump is functioning properly, refill the hot tub with water.
- Check for Leaks: Inspect the plumbing connections for any leaks. If you find any, turn off the pump, drain the tub again, and reseal the connections as needed.
- Monitor: Keep an eye on the pump and plumbing for the next few days to ensure everything is functioning correctly and that there are no further issues.
Remember that this is a general guideline, and the specific steps may vary based on your hot tub's design. If you're unsure or uncomfortable with any aspect of this process, please do get in touch, happy to help.
How do I know what size hot tub pump I have?
Determining the size of your hot tub pump is an important step when it comes to maintenance or replacement. To find out the size of your hot tub pump, follow these steps:
- Check the Manual: The easiest way to determine the size of your hot tub pump is to consult the owner's manual or user documentation that came with your hot tub. The manual typically contains detailed information about the specifications and components of your hot tub, including the pump.
- Look at the Pump Housing: If you don't have access to the manual or it doesn't provide the information you need, inspect the pump itself. Most hot tub pumps have a label or plate on the pump housing that displays essential details, including the pump's model number, manufacturer, and specifications. You can then send that to me or Google it.
- Measure the Pump: If the label is missing or damaged, you can measure the pump's dimensions. Measure the diameter of the pump's wet end (the part where the water flows) and the length of the wet end. These measurements can help identify the size and capacity of the pump.
- Consult the Manufacturer: If you can't find the information on the pump or in the manual, contact the hot tub manufacturer or a reputable dealer. Provide them with your hot tub's model and serial number, and they should be able to identify the correct pump size for your specific hot tub.
- Online Research: You can also search online using the pump's model number or hot tub's make and model. Many manufacturers provide detailed information about their products on their websites, and you may find specifications for your pump model.
Once you have determined the size and specifications of your hot tub pump, you can proceed with maintenance, repairs, or replacement if necessary. Keep in mind that replacing a hot tub pump with the same size and capacity as the original is crucial to ensure proper water circulation and filtration in your hot tub. If you're unsure about any aspect of this process, get in touch, always happy to help.
