RED RHINO Pro-Pumps1.3 KW Drainage Pump Debris Cutter User Manual

WARNING

• Electric pump must be reliably grounded before using the pump, must be installed with leakage protection device and overload or over-current protection evice.
• Running the electric pump without water is strictly prohibited.
• Never touch the water near the pump when it is running.
• To prevent electric shock,turn off the power before maintaining and cleaning the electric pump

Product introduction

Submersible sewage pump is important equipment for sewage treatment.Its compact structure,ease of use and maintenance,and large-channel hydraulic components will ensure that solid particles and cotton yarns,weeds and otherfibers pass smoothly,so that the pump has excellent over-current performance, wide range of operation,high reliability of operation, facilitated automation, and other advantages.It is widely used in municipal works,urban industrial,commercial facilities, hotels,residential communities for sewage discharge and the mining construction and other water media with solid particles,or oil extraction and farmland irrigation, etc.

Requirements for use

1. The water temperature should be no higher than +40℃;
2. The maximum submersing depth should not exceed 10m.
3. The PH of water should be in 6.5-8.5.
4. The maximum diameter of passable sol id particles: Ø15~Ø35mm.
   

Installation and use

1. Submersible pump must be used within the range of the recommended head,so as to prevent damage on the motor due to overloaded operation.To select the pump head,user should consider pipeline and bend loss.

2. After unpacking,fully check if there is any damage on the pump during transportation and storage,for example,if the cables, plugs are intact, if the joints are tight without seeping or oil leakage. Promptly ask professionals to repair or replace the damaged parts, if any.

3. Before using the pump, fully check its insulation resistance, and the cold insulation resistance should be no less than 100 MΩ.
   

4. When cleaning the pool or channel, check if the minimum water level of the intake pool meets\ the requirements for installation.
   

5.  To install the electric pump in pond, hoist it witha tripod or assisted by boat, bridge or wharf, do not place it directly at the river bottom, otherwise the motor may gradually get stuck in the mud to cause blockage, get too high temperature, and burn out the motor.
   

6. To hoist the pump, user must turn off the power to ensure safety. The electric pump must be used at an appropriate voltage. If the power supply is far from the place where the electric pump is used , the extended cables should be appropriately thickened according to the distance,the connectors should be sealed and bound with water proof insulation tape, so as to make sure it insulated and off the ground. If necessary, ask a professional electrician to test if the operating voltage of the pump is within ±10% of the rated voltage,so as to avoid under-voltage operation because the cable is too long and the voltage drop is too great, which may cause burnout.
   

7. Before diving the pump into the water,turn on the power for test run, confirm the rotating direction of the impeller before starting it, but it should not exceed 3s. The cable of the single-phase pump should be strictly as per the wiring diagram as indicated on the motor or the control box,and should be wired by the corresponding colors.Incorrect wiring will cause the pump to work abnormally and may damage the motor;the three-phase pump can be wired despite the colors, when the pump rotates in the reversed direction (from the end of motor shaft, the correct direction is indicated if the motor\ rotates counterclockwise), just change the connection of any two lines.

8. The elec tri c pump should separatel y use appropriate protection switch, in case of frequent tripping of the switch, never force start it, check if the electric pump is failed, otherwise the motor may be easily burnt out.

9.  To dive or lift the pump out of the water, usermust hold the hoist ring or handle with steel wire rope, never pull the cable at random. When operating the motor, it is preferably to keep the cable off the ground, so as to avoid crushing it when the heavy object passes on the ground ,which may cause an accident.
   

10. When using the electric pump, if float switch or liquid level detector and other protective measures are not provided, the pump should be tended by a specific person, so as to avoid it from running without water due to reduced water level. In case of abrupt reduction ofwater,abnormal sound ,or violent vibration, immediatelyturn off the power , and stop using it until the cause is identified.
    

Precautions

1. When hoisting the equipment, never directly lift the cable or hoist any other heavy object with cable;
2. It is strictly prohibited to dip the end of the cable into the liquid.
3. The housing of all equipment should be reliably grounded to prevent electric shock.
4. The inner diameter of the outlet pipe should meet the specifications (in principle, not less than the outlet diameter of the pump).
5. Do not place the su b m e r s i b l e sewa g e pump at the sewage inlet. When the pump is placed on mud or floating sand,the pump may sink due to vibration,and in this case, it is recommended to place the pump on a larger base plate.
6. The housing of the pump if used in sewage will accumulate slurry, debris to reduce the rate of heat transfer,cause temperature rise in the motor, shorten the service life of the stator,or cause tripping for no reason,please remove debris (at least once a year) after sucking the sewage to the minimum level

Repair and service

• Before repairing and servicing,make sure that the pump is flushed with clean water,after disassembling the pump,flush the over-current parts with water.
  1. The normal operation of the pump should be checked at least once a year.If the liquid pumped is turbid or the sediment concentration is large,shorten  the time intervals of checking the pump.
  2. The following points should be checked:
• Energy consumption: If there is anomaly,check if the circuit is significantly increased.
• Oil condition: If the oil contains water,it will be as gray as milk,there may be a leakage of mechanical seal.
• Cable: Make sure that the cable is still sealed without obvious bending r shrinking.
• Over-current components of the pump: After it is used in the sewage for the middle and long term,the impeller is worn, with lower flow and efficiency.

When the temperature is below 0℃ if the pump can normally operate, you can continue to use,otherwise place it in a well-ventilated and dry area. 5

• Bearing: Check if the bearing is damaged or its rotation becomes inCCflexible.
  Note: To check the electric pump, ask professionals to repair or replace.

Make sure that the power is turned of f before uncovering the junction box of the motor and disassembling the pump.
