Do not cover the motor with any thermal insulation materials, for such a material will result in bad ventilation and thermal dissipation and even a fire easily.

Product Introduction

Mini-type Clean-water Electric Jet Pumps(hereinafter referred to as the ” Electric Pump”) cover series of CAM, SGJS, JET, CGP and AUTOJET-A. The Electric Pump is composed of such three parts as the motor, the water pump, and the seal. The motor is an asynchronous motor. The pump adopts the unique structure of centrifugal-type impeller-radial guide vane-jet pipe, whose principle is that the pressure water firstly goes through the nozzle to form vacuum and then the liquid at a low water level is absorbed to the inlet of the pump and discharged through the pressurization by the pump, featured by deep suction stroke, high lift, short self-priming time, and stable operation.
The Electric Pumps of the models hereunder, with advantages such as small volume, light weight, compact structure, and easy installation, can be widely applied to lifting of water from wells, pipe pressurization, agricultural irrigation, water supply to vegetables greenhouses, supply of domestic water, and breeding industry.

Operating Conditions

The Electric Pump shall be able to operate continuously and normally in the following operating conditions:

1. The ambient temperature does not exceed +40°C;
2. The temperature of the medium ranges from 0 to +40°C;
3. The PH value of the medium is 6.5~8.5;
4. The mass ratio of the solid impurities contained in the medium is not higher than 0.1% and particle size is not more than 0. 2mm;
5. The voltage and the frequency of the power supply meet the requirements in the nameplate of the Electric Pump, relating to the nominal voltage and frequency and the scope of the fluctuation of voltage is ±10% of the nominal value.

Instruction for Installation

Prior to installation and use, please fully check whether the Electric Pump is damaged during transportation or storage for example, whether any cable or outgoing line or plug (if provided) is in a perfect condition. In case of any damage, please have a specialized person make replacement or repair. The insulation resistance shall be greater than 50MΩ.

During installation, the complete machine shall be fixed and the inlet and outlet pipes shall be separately supported, whose weight shall not be completely supported by the pump body.

1. Use a steel or rubber pipe (which shall not be too soft so as to avoid becoming flat in case of absorption) to connect the bottom valve and the inlet end of the Electric Pump. Please make sure that the inlet pipeline and its connections are sealed and present no air leakage.
2. Connect the outlet pipe firmly to prevent water from splashing on the motor, thus causing electrical leakage of the Electric Pump. When a rubber pipe is used, pay attention to its temperature resistance limit to ensure that the pipe will not be deformed by heat, for such deformation might make the pipe become broken, causing water leakage.
3. After connecting the upper end of the inlet pipe and the inlet end of the Electric Pump, please make sure that the end of the inlet pipe, where the bottom valve and the strainer lie, is submerged in water. To guarantee the reliable use of the Electric Pump, please arrange an effective strainer which, together with the bottom valve, shall keep more than 30cm away from the water bottom, for the purpose of preventing sludge or impurities from being absorbed to the pump chamber and hence affecting the operation of the pump.
4. Make a pipe as short as possible to reduce connections. The drawing-up height shall not exceed the suction lift.
5. During use, please pay attention to the decrease of the water level and do not let the bottom valve or the lower end of the inlet pipe come out of water.

1. Prior to the initial use, please fill the chamber of the Electric Pump with water and then turn on it so as to avoid dry running.
2. A self-priming pump will start only when its pump body is filled with water and it is unnecessary to fill the inlet pipe with water; in case of a non-self-priming pump, both its body and inlet pipe shall be filled with water and air shall be drained completely.
3. In an area with high sand content, it is recommended that a Y-shaped filter should be installed at the inlet pipe to prevent sand from entering the pump chamber and hence causing a worn or blocked impeller.
   

Prior to the use of the Electric Pump, please carry out a test run of which the duration shall not exceed 10s, as longtime dry running will damage the mechanical seal. In case of a three-phase pump, please check whether the rotational direction is the same as the rotation mark. When finding the reverse rotation of the Electric Pump, immediately cut off the power supply and exchange any two phases of the three-phase pump.

With the valve closed at the outlet, the Electric Pump shall not operate for over 5 minutes. When the Electric Pump operates with no water flow change inside the pump body, it shall lead to the rise of the temperature and the pressure of the liquid in the pump body, and may cause an electrical leakage or damage the pump or pipeline.

If the user wants to make the Electric Pump do automatic control, a proper pressure control device shall be arranged on the outlet pipe only.

To equip a three-phase electric pump with an overload protection device, a suitable overload protection device shall be selected on the basis of current or power.

To add a wire for the plug or replace the wire, please use a wire whose specifications are the same or higher than those of the original wire and pay attention to making firm connections, water-proofing and insulation.

1. Install the Electric Pump as a dry and well-ventilated place where repair and inspection can be carried out easily. To install the Electric Pump at a narrow place, please follow the following diagram and keep the fan cover more than 25cm away from the wall, in case of heat dissipation.
2. Arrange a drainage ditch around the Electric Pump to form natural drainage and prevent water leakage and loss during the usage, repair, or replacement of the Electric Pump (especially at a basement, kitchen, or stairway).
   

To adjust the pressure switch, open the housing of the pressure switch by using a slot-type screwdriver or wrench to rotate the pressure adjusting screw toward”+”. A non-specialized person shall adjust the switch under the condition of power-off and a specialized person shall take safety protection measures in case of operation under power-on.

The packing materials removed after installation and use shall be disposed in accordance with the concerned local law.

1. Regularly inspect the insulation resistance between the enclosure and the winding of the Electric Pump, which shall be no less than 5M when the operating temperature is nearly achieved, or otherwise usage shall not be allowed until the corresponding measures are taken and the relevant requirements are met.
2. Prior to any repair or maintenance operation, please cut off the power supply and make sure that the motor will not be turned on for operation due to a casual operation.
   Warning
   

After the 2000-hour normal usage of the Electric Pump, the Electric Pump shall be delivered to a qualified repair station for maintenance and repair as per the steps below: dismantle the pump and inspect various quick-wear parts such as the bearing, mechanical seal, impeller, guide vane, check valve, bottom valve and jet pipe. Please immediately replace those damaged ones.

Air tight test: After the pump is disassembled for the repair or replacement of any seal, the bearers and the complete pymp shall go through water (air)pressure tests on the basis of the maximum operating pressure and such a test shall last for 3 minutes and there shall be no phenomenon of leakage or sweating.

• When the ambient temperature is lower than 4C, please completely drain the water accumulated in the pump chamber to avoid frost-cracking the pump body. Before starting the Electric Pump again, inspect whether the pump spindle rotates flexibly and fill the pump chamber with water.

• In the event that the Electric Pump has not been used for a long time, please disassemble the piping, drain the water accumulated in the pump, clean the main parts and components, carry out rust-proof treatment, and keep it properly at a dry and well-ventilated place.
  

• The recycling of the Electronic Pump shall comply with the local laws and regulations concerning recycling.
