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.
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 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.
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.
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 +
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.
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
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)
