Introduction

The deep-well pump is a water lifting tool based on direct connection between electric machine and water pump, which is suitable to fetch underground water from deep wells or rivers, reservoirs and canals etc in some projects. Further, this product is mainly used for farmland irrigation as well as 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

2.1 Voltage fluctuating range shall be ±10% of rated values;
2.2 The water temperature shall not be higher than +95°F.
2.3 The PH value of water is between 6.5 and 8.5.
2.4 The solid contents in the water shall not be larger than 0.25% with the maximum diameter not over 0.09inch.

Installation and notice

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, the air compressor or old water pump shall be used to clean sundries and soils.
After that, please check whether the water quality and temperature conform to use conditions. The water pump can only be installed with the water inside the well up to standard.
3.2 Please check the damage that may be caused in the transportation and storage process after unpacking the pump.For example, whether the cable and plug are intact; various joints are not loosened without any leakage. If with any damage, please contact with professional personnel to repair or replace it.
3.3 During installation, please fix the electric pump and then install earth leakage protective device or over-heat or over-current protective device correctly. The electric pump must be connected to the ground reliably.
3.4 When the water pump reaches a certain length, the motor and the pump body need to be packed separately.

• In case of a separate packing, first remove the filter screen and cable protection plate from the pump body (Figure1 ), then place the pump body on the motor to make the spindle head of the rotor smoothly slide into the coupling, manually rotate the coupling to check if it can run normally, then screw up the connecting bolt(Figure2), and finally install the filter screen and cable protection plate(Figure3).

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, and the cold insulation resistance should be not less than 100 MO.
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 pump shall be connected according to the wiring diagram on the electric machine or control cabinet strictly with correct colors. The wrong wiring will cause abnormal works or even damage the electric machine; three-phase water pump can be connected without differentiating cable colors.
3.7 A power line can be added with rather distant power supply. Please select proper cable lines according to table to avoid too thin cable that will lead to abnormal operation.

To choose the required cutting area of cable according to the power of pump and length of external cable to ensure the normal operation of motor.3.8 Please operate as below instructions for adding cable lines: List ofSplice Kit A
Attention: There are three strands of wires from the pump cable. BLACK – HOT WIRE (11 0V); BLUE – HOT WIRE (110V); YELLOW- GROUND WIRE (PE).

The drive will operate on single-phase Hot-Hot-Ground electrical systems. This pump must be permanently connected by a circuit breaker as specified in the local electrical code.
Please pay attention to correct matching when adding an extension cable.
Be sure to cut off the power supply before wiring to avoid electric shock and accidents. If there is any question, please consult an electrician or contact Acquaer customer service email: service@acquaerpumps.com

3.8.1 Prepare the pump wire extension. Strip the cable by 2 inch to 3 inch with a wire stripper, then strip the insulation to reveal 1 inch copper wire. Place the black heat shrink tube over the main cable.Then place the small white heat shrink tubing over each individual wire.

3.8.2  Insert the stripped needs of the extension wire into the butt connectors in the wire pigtail from the pump. Firmly crimp each splice with crimping plier to tightly hold the wires in place. Attention: Please pay attention to correct matching when adding an extension cable.

3.8.3 Slide the small heat shrink tubing over the butt connectors and wire and then use a heat gun or lighter to evenly heat the shrink tubing on all sides and shrink the sleeve over the wires. The tubing contains adhesive and will make the joint waterproof. Make sure to heat the tube enough that adhesive squeezes out a bit from the ends of the connection.

3.8.4 Winding the rubber splicing tape on the butt splice connections of three strands of wire.

3.8.5 Wrap the three wires together with the hot melt adhesive. Thicker at both ends.3.8.6 Slide the black heat shrink tube over the connection and evenly heat it on all sides with heat gun or lighter. Make sure to heat the tube enough that adhesive squeezes out a bit from the ends of the connection.

3.8. 7 Winding the waterproof electrical tape over the shrink tubing and wire.
3.8.8 lmmerge the junction of the cable into water for 12 hours. Test the insulation resistance of the cable with the 500V megohmmeter. The cold insulation resistance should be not less than 50 MO.

3.9 The delivery pipe shall be matched to the water outlet ( the specification shall be selected based on performance parameter table). For example, the iron wire or clamp can be used to connect with soft delivery pipes; the screwed joint can be used for steel delivery pipes for further reliable connection. Further, the threading ropes are used at the handle in case of lifting in the water.
The tied ropes of hoisting electric pump must be firm and durable. The cable lines shall not be stretched but in a natural loose state.
3.10 The cables are not allowed for impact and crushing or used as lifting ropes. Further, do not pull the cables randomly during operation so as to avoid electric shock caused by cable damage.
3.11 The electric pump should be no deeper than 262 ft in the water, but should be 10 ft above the bottom. Further, the electric pump shall not be sunk into soils. Meanwhile, the user shall prevent sundries to block nets or impellers, because it will lead to abnormal works. Please check the water level during works to avoid e posed or dry works, or else 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 equipped with appropriate food machine oil at the time of ex-factory. The 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 equipped with food machine oil that may be leaked during damage or breakdown. Under the use environments such as planting, cultivation or drinking water, food transportation and processing 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 consequence before selecting this product so as to confirm its proper use. If necessary, please invite some related professional personnel. If with food machine oil leakage, please stop using and deal with it properly.
3.15 The power source shall be cut off at the time of adjusting position or contacting with electric pumps in case of any accidents. The electric pump shall not be lifted away from water surface after shunting down power source so as to guarantee safety.
3.16 The electric pump belongs to specialized technology-based product. The unqualified repairman shall not conduct any random disassembly. The sealing and insulation testing must be conducted after laid-up and reassembly.
3.17 The maintenance shall be conducted on electric pumps after 3,000 hours normal operation. Various easily damaged parts such as mechanical seal, bearing and impeller etc must be replaced. The air pressure test must be conducted on motor and oil chambers after laid-up or changing 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 nonuse. Instead, the pump shall be put in the clear water for several minutes of operation so as to clean mud etc inside and outside the pump. Further, the anti-rust oil shall be coated o the pump that 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.
