  • Common failures of self-priming pumps
    During the daily use of the self-priming pump, there will be some more common problems. For example, the self-priming pump's non-pumping problem will be caused by many different reasons, so how do we deal with these problems is the key. The reasons why the self-priming pump does not pump water include the following aspects.
  • Classification and difference of submersible pumps
    The hot water submersible pump is used for hot spring bathing, and can also be used for extracting groundwater from deep wells, and can also be used for water lifting projects such as rivers, reservoirs, and canals. It is mainly used for farmland irrigation and human and animal water in high mountain areas. It can also be used for central air conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines, and construction site drainage. The general flow rate can reach 5~650m³/h, and the head can reach 10-550 meters.
  • Diaphragm pump application advantages
    Diaphragm pump is a new type of conveying machinery that can convey various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids. Diaphragm pump has four materials: plastic, aluminum alloy, cast iron, stainless steel.
  • Submersible pump for winter flooding
    Winter is when the risk of flooding is at its highest. If you live in an area that’s susceptible to floods, you’ll already know the risks. But even if you’re not in a high-risk area, there’s still a chance that heavy rainfall could lead to raised ground-water levels or water flowing into cellars.
  • How to select a submersible pump
    There are four important criteria for selection of your pump. Bore well size : The diameter of the bore is the restricting Factor e.g. If your bore size is 100mm then select 100mm Pumpset only. Total head : Please Understand head as below : Total head =A+B+ Draw Down level + Seasonal Variation in water level + Frictional loses.
  • Pump installation, use and maintenance
    Installation Instructions: In installation, the pipeline weight shall not be exerted on the water pump but supported respectively lest the pump will be deformed to affect its working performance and life. The pump and the motor are integrated, unnecessary for alignment in installation, so its installation is very easy. In installation, anchor bolts must be fastened lest the vibration of starting will affect the pump's performance. Before installing the water pump, it's necessary to check carefully whether there are any hard matters (such as stone and iron grit) affecting the pump's running in its flow channel lest they will damage the pump's impeller and body during running.
  • Industrial voltage and frequency in other countries
    Argentina: voltage: 220V (single-phase) 380V (three-phase), frequency: 50Hz Brazil: voltage: 110/220V (single), 380/460V (three-phase), frequency: 60Hz Canada: voltage: 120/240V (single), 208/240V (three-phase); Frequency: 60Hz Mexico: voltage: 127/220V (single), 220V (three-phase); Frequency: 60Hz
  • How to select the right vacuum pump
    No single vacuum pump can meet all the above criteria completely. Let us now see some of the widely used pumps for distillation along with their limitations. Ring type pumps (e.g., water ring pump, oil ring pump)
  • Centrifugal pump trouble shooting
    Pump not primed, both the hands of vacuum gauge and manometer switches violently Pump not primed and high degree vacuum indicated on the vacuum gauge
