How to choose a macerator lifting pump?

The discharge and treatment of sewage is a relatively important matter in city life. What we need to know is that the treatment and discharge of sewage require the use of professional sewage treatment equipment - macerator lifting pumps. What kind of macerator lifting pump is a good one? How to choose a good macerator lifting pump? The following will explain to you how to judge the quality of the macerator lifting pump.

1. FLOW

The flow rate of the macerator lifting pump refers to the discharge per hour, and you should choose it according to your own situation. If you are renovating your home, and you may only have one kitchen or one bathroom, then you only need to choose a normal flow rate of 5-10m³/h, which is enough. Of course, if you need to add more than one bathroom, or need to discharge wastewater from washing machine etc., you can choose a macerator lifting pump with a larger rate flow. If possible, you can also choose a macerator lifting pump with a dual-pump system. In public places, it is recommended to choose a macerator lifting pump with a dual-pump system.

2. HEAD

The head of a macerator lifting pump refers to the maximum height at which sewage can be lifted. Is the higher the better? Of course not. If you live on the basement, the height of your house may be only 3-5m. If there is pipe loss, you only need an actual head of 5-8 meters, but you need to ensure that the actual head is 5-8 meters. When the pump is used, the flow rate must still be sufficient for use. Otherwise, some maximum head is only 5 meters and the max flow rate is very small. If you choose an integrated macerator lifting pump, you must pay attention to the curves of flow rate and head.

3. Grinding or pipe diameter

This refers to the maximum diameter of debris that can be removed by the water pump drainage pipe. If it is not connected to the toilet, 10mm is usually enough. If the vortex-type macerator lifting pump connected to the toilet needs to ensure a minimum filter diameter of 38-50mm. Of course, the most ideal way is to choose a grinding and crushing macerator lifting pump. The particle size after grinding and crushing is recommended to be less than 2mm. The grinding and crushing macerator lifting pump is about 20% more expensive than the vortex one. If the oil content in the discharged sewage is high, it is recommended to choose vortex-type sewage lifting equipment.

The above are the three important element of the macerator lifting pump. The next question is how do we judge the quality of the macerator lifting pump? Its relative to the other parameters of the macerator lifting pump.

4. Protection level

Some of the protection levels of small macerating pumps are IP44. Of course, the higher protection level, the better of quality. Say the protection level IP54 or IP68. The higher the protection level means the higher of safety and the better of dust-proof and waterproof performance. If possible, it is recommended to give priority to IP68 macerating pumps.

5. Material

Generally, the material of macerating pumps is PP/PE/ABS. It depends on the applications. ABS has the highest corrosion resistance. HDPE is more suitable for macerating pumps with large boxes. Its not the good options to choose a stainless steel welded box, because the stainless steel box is only 2-3mm thick, the final weld will crack during the vibration work of the macerating water pump, and its will leak at any time. Later maintenance is very difficult. In generally, the professional manufacturer will create their own mold. The macerating pump with a plastic shell is more resistant to corrosion and has no hidden dangers of water leakage. Creating a new mold which requires a large investment and certain skills.

6. Heat dissipation performance

When the macerating pump is running, the speed and the heat is very high. The heat dissipation capacity becomes an important indicator to measure it. Depending on the material of the motor and the material of the motor shell, Its a reliable company which have ability to produce a built-in macerating pump. Because it need attention on the effects like good protection level, sustainable running and multiple cooling effects. Pumps that outside the water tank generally have lower technical content and poorer heat dissipation.

7. Start control

The macerating pump running in what situation and how to control it? Most of macerating pumps in the market now use liquid control and aerodynamic control. It is best for small macerating pumps to work with liquid control. Liquid controlled can be connected to equipment with large drainage volumes such as bathtubs and washing machines to accurately control the liquid level. It is best for commercial sewage lift pumps to adopt liquid control to discharge wastewater containing fixed particles, such as feces. For the discharge of sewage with a relatively large oil content, it is recommended to choose aerodynamic control.

These are the more important common sense when purchasing a macerating pump. In addition to these aspects, we also need to consider other factors when purchasing.

8. Lifetime

The longer life is the better, because replacement and maintenance are troublesome. Many people started to buy some cheap macerator lifting pumps from small factories to save costs. In the last few years, the cost of maintenance and replacement has exceeded that of buying a safer and more stable macerating pump. So try to choose a reliable macerating pump manufacturer. For more reliable performance, you cannot blindly pursue price, otherwise you will end up losing more financial costs.

9. Maintenance

Failure of the macerating pump will still happen. If it fails, it will be very difficult for many brands to open and repair it. Therefore, when choosing a brand of macerartor lifting pump, you must choose an excellent installation team to carry out professional installation.
