Introduction
The deep-well pump is a water lifting tool based on direct connection between an electric machine and a water pump. It is suitable for fetching underground water from deep wells, rivers, reservoirs, and canals in various projects. This product is mainly used for farmland irrigation, as well as for human and animal drinking water in plateau mountain areas. More importantly, the deep-well pump can be used for water supply and discharge in cities, factories, railways, mines, and construction sites.
Use Condition
- Voltage fluctuating range shall be ±10% of rated values.
- The water temperature shall not be higher than +35°C.
- The PH value of water is between 6.5 and 8.5.
- The solid contents in the water shall not be larger than 0.25% with the maximum diameter not over 2.3mm.
Installation Use and Notice
WARNING:
- Reliable grounding must be conducted before using the water pump. The earth leakage protective device as well as the overload or over-current protective device must be installed on the water pump.
- The electric pump is not allowed for dry running.
- When the pump is in operation, people and animals shall not touch the water near the pump.
- To prevent electrical shock, the power source shall be shut off during maintenance and cleaning.
- If the power cord is damaged, it must be replaced with a special flexible cord or a special component purchased from its manufacturer or maintenance department.
Installation Steps & Notices:
- 3.1 Please check whether the inner diameter conforms to the minimum diameter of water pumps before buying and installing. If it is a new well, use an air compressor or old water pump to clean sundries and soils. After that, check whether the water quality and temperature conform to use conditions. The water pump can only be installed into the water inside the well up to standard.
- 3.2 Please check for damage that may have been caused during transportation and storage after unpacking the pump. For example, check if the cable and plug are intact; ensure various joints are not loosened and without any leakage. If there is any damage, please contact professional personnel to repair or replace it.
- 3.3 During installation, please fix the electric pump and then install the earth leakage protective device or the over-heat or over-current protective device correctly. The electric pump must be connected to ground reliably.
- 3.4 When the water pump reaches a certain length, the motor and the pump body need to be packed separately.
Assembly of Pump Body to Motor (if packed separately):

Figure 2: Shows placing the pump body on the motor, aligning the spindle head of the rotor smoothly into the coupling. Manually rotate the coupling to check if it runs normally, then screw up the connecting bolt.
Figure 3: Shows installing the filter screen and the cable protection plate.
- 3.5 Before use, thoroughly test the insulation resistance of the electronic pump's stator winding (including outgoing cable) to the pump casing with a 500V megohmmeter. The cold insulation resistance should be no less than 100 MΩ.
- 3.6 The electric pump shall be connected to the power source for trial operation before entering into water. The time shall not exceed 3 seconds. The cable lines of single-phase water pumps shall be connected according to the wiring diagram on the electric machine or control cabinet, strictly connected by correct colors. Wrong wiring will cause abnormal operation or even damage the electric machine. Three-phase water pumps can be connected without differentiating cable colors.
- 3.7 A power line can be added for a distant power supply. Please select proper cable lines according to the table to avoid the cable being too thin, which can lead to abnormal operation.

Cable Line Instructions
Please operate as below instructions for adding cable lines:
- 3.8.1 Strip a 50-60mm cable with a wire stripper, then strip the rubber hose to reveal a 20-30mm copper wire.
- 3.8.2 Tighten two cable lines with the same color into a spiral shape to guarantee a close connection.
- 3.8.3 Tightly wind and cover the cable with electrical insulating tape from the 15-20mm core cord.
- 3.8.4 Wrap the cable, covered with electrical insulating tape, with a waterproof adhesive tape from the 20-30mm core cord. The waterproof adhesive tape should be 10mm longer than the electrical insulating tape at both ends. Before wrapping, the waterproof tape should be stretched out 1-fold its length and follow normal use.
- 3.8.5 Wrap the cable, wrapped with waterproof adhesive tape, with electrical insulating tape.
- 3.8.6 Wrap the cable, wrapped with electrical insulating tape, with waterproof adhesive tape. The waterproof adhesive tape should be 10mm longer than the electrical insulating tape at both ends. Before wrapping, the waterproof tape should be stretched out 1-fold its length and follow normal use.
- 3.8.7 Immerse the junction of the cable into water for 12 hours. Test the insulation resistance of the cable with a 500V megohmmeter. The cold insulation resistance should be no less than 50 MΩ.
3.9 The delivery pipe shall be matched to the water outlet (the specification shall be selected based on the performance parameter table). For example, iron wire or clamp can be used to connect with soft delivery pipes; a screwed joint can be used for steel delivery pipes for a more reliable connection. Further, threading ropes are used at the handle in case the rope floats in the water. The tied ropes for hoisting the electric pump must be firm and durable. The cable lines shall not be stretched but remain in a natural loose state.
Safety Precautions and Maintenance

- 3.11 The depth of the electric pump in the water shall not be over 80m, but must be at least 3m above the bottom. Further, the electric pump shall not be sunk into soils. Meanwhile, the user shall prevent sundries from blocking nets or impellers, as this will lead to abnormal operation. Please check the water level during works to avoid exposed or dry works, or it will burn the electrical machine and other parts.
- 3.12 During usage, washing, swimming, or animals are not allowed within working regions. The safety warning label "Electric shock risk, no entry" shall be set up on the site to prevent accidents.
- 3.13 The oil-filled electrical machine has been filled with appropriate food machine oil at the time of ex-factory. Users are not allowed to fill in any water or oil into the electrical machine (except for maintenance).
- 3.14 The oil-filled electrical machine is filled with food machine oil that may leak when it is damaged or breaks down. Under use applications such as planting, cultivation, or the transportation and processing of drinking water and food, etc., the leaked food machine oil may cause certain damage to plants and cultured animals or pollute drinking water or food. The user shall evaluate the use environment as well as related consequences before selecting this product to confirm its proper use. If necessary, please invite related professional personnel. If there is food machine oil leakage, please stop using and deal with it properly.
- 3.15 The power source shall be cut off when adjusting position or contacting with electric pumps in case of any accidents. The electric pump shall not be lifted away from the water surface before shutting down the power source to guarantee safety.
- 3.16 The electric pump is a specialized technology-based product. Unqualified repairmen shall not conduct any random disassembly. Sealing and insulation testing must be conducted after laid-up and reassembly.
- 3.17 Maintenance shall be conducted on electric pumps after 3,000 hours of normal operation. Various easily damaged parts such as mechanical seal, bearing, impeller, and so on must be replaced. The air pressure test must be conducted on motor and oil chambers after laid-up or changing the mechanical seal. The test pressure is 0.4 Mpa. There shall be no leakage within five minutes.
- 3.18 The pump shall not be sunk into water for long-term non-use. Instead, the pump shall be run in clear water for several minutes of operation to clean mud and other dirties inside and outside of the pump. Further, anti-rust oil shall be coated on the pump, then it shall be put in a dry and ventilated place. The electric pump with rather long-term use shall be repainted or treated by anti-rust oil according to its surface corrosion status.
