| Safety Switch | ||
| HK-SS100/120 | Safety Switch for HK-100L & 120L | The Safety Switch is only used with the Hakko 100L and Hakko 120L air pumps. It is designed to protect the motor and magnet from damage. Under normal operation the diaphragms in your pump will gradually wear out or tear. The magnet is attached to the diaphragms. If the diaphragms fail then the magnet will be out of balance and will vibrate loudly. The safety switch senses the excess vibration and turns off the motor to save wear and tear on other parts. Sometimes during shipping a new pump may have been jarred enough to through out the safety switch. The brand new pump will not turn on right out of the box. Simply remove the top of pump cover and you will see the safety switch at the top of the motor. Notice the small circle with an arrow on it. Just use a coin or flat head screw driver and re-align the arrows. If re-aligning the arrows does not turn on the pump then you may need to purchase a new safety switch. Please check for loose wires. They are relatively simple to replace. |

| Diaphragms | ||
| HK-D25 | Replacement Diaphragm for HK-25 | Our rebuild diaphragm kits are simple to install. Refer to our trouble shooting section for directions on proper replacement procedure (See bottom of this page for links and videos). Tools you will need: – 1 medium phillips screwdriver – 1 small phillips screwdriver – 1 medium pair of pliers Note: If your diaphragms are blowing out frequently, you most likely have an excess back pressure problem in your design. Check that your air delivery tube is large diameter and no kinking is occuring. Check your air diffusers for clogging. Ceramic style air stones need cleaning with muriatic acid every 3 months typically. Check that the number of air diffusers is sufficient to handle the air output of your Hakko pump. Too few diffusers will create excess back pressure. Read our article on “Air Pump Troubleshooting and Tips” below. |

| Magnets | ||
| HK-M25 | Replacement Magnet for HK-25 (1-piece) | The magnet is the part that moves back and forth between the diaphragms. It is held in place by the diaphragms. Typically, the magnet is very long lasting. However if you run the air pump with bad diaphragms for extended periods you could wear down the magnet. If you open the motor for repair and you find gray dust or small metal particles in and around the motor, you may need to replace the magnet. Always inspect the magnet for wear and tear when you replace your diaphragms. They are very easy to replace. See the helpful picture guide below “Air Pump Magnet Measurements”; which will help you identify the correct magnet if you are unsure. Read through the “Hakko Troubleshooting Tips and Information” below for more help. |
