How to Know Deep Well Pump and Shallow Well Pump?

Deep well pump is also called "long shaft deep well pump". Most deep well pumps are vertical single suction multi-stage centrifugal pumps. The impellers of deep well pumps are installed below the dynamic water level in the well. The power machine is installed on the well. The impeller is driven by a long shaft to rotate in the guide case. The water flow rises up to the ground through the water conveyance pipe along the channel between the guide case and the impeller..A well pump specially designed for pumping deeper water bodies. Deep well pumps are vertical single suction sectional multi-stage centrifugal pumps or vertical multi-stage mixed-flow pumps. The head is more than 50 meters. Some countries stipulate that the head is more than 300 meters before it is called "deep well pump". It is customary to call its accessory device "deep well pump". It consists of three parts:

(1) the upper part of deep well pump. Including pump base, motor or internal combustion engine, transmission device, etc.

(2) The middle part of the deep well pump. Including water pipes, transmission shafts, bearings and so on.

(3) The pump body of deep well pump includes impeller, rubber bearing, diversion shell, intake pipe, filter screen, etc. The impeller of deep well pump is composed of multi-stage centrifugal impeller or mixed-flow impeller in series, which can pump water from wells several tens to hundreds meters deep. However, the rotating shaft is long, the steel consumption is large, the installation and maintenance is troublesome, the processing accuracy of water pipeline is high, and the transmission efficiency is low.

For the shallow well pump, the shallow well pump is a kind of well water pump to extract shallow water body. China calls the well pump with a lift of less than 50 m "shallow well pump". It is customary to call its accessory device "shallow well pump". It consists of three parts: the upper part is usually equipped with a power engine, a vertical motor or an internal combustion engine; the middle part is a water outlet pipe and a transmission shaft; the lower part is a pump body, which is usually equipped with 2-8 centrifugal or mixed-flow impellers, and the inlet pipe is equipped with a water filter. The utility model has the advantages of simple structure, reliable operation and high working efficiency.

What is difference between a shallow well pump and deep well pump ?

Submersible pumps and deep well pumps have in common the potential of underwater pumps. The difference is that the general submersible pump is a single-stage impeller, with small lift, large pump body and low power. Deep well pumps are multi-section pumps with large lift, small and long pump body suitable for small caliber deep water wells, and high power. The quality of deep well pumps is relatively better. Deep water pump and submersible pump belong to centrifugal pump, and their working principles are the same and their structures are different. Deepwater pump has a slender structure. The motor and impeller are connected by a long axis. The motor is generally above the water surface and suitable for working in a slender space. Submersible pumps, motors and impellers are integrated through mechanical seals and work under water as a whole. They are suitable for large space extraction. There are two kinds of deep-well pumps: deep-well submersible pumps, i.e. deep-well submersible pumps and long-axis deep-well pumps, motor submersible at wellhead and pump head submersible.

Simply put, the submersible pump in use is the pump body is the potential water, while the deep well pump is not in the water, but there is a pipe stretching in the water. Generally speaking, the power of the submersible pump is small, and the power of the deep well pump is relatively large. For Vertical Turbine Pump, Submersible Deep Well Pump is also applicable
