Installation of CDLF type vertical stainless steel multi-stage pump:

1. The CDLF vertical stainless steel multi-stage pump should be installed vertically on the ground,. Ensure that sufficient cold air enters the motor cooling fan during installation. The arrow at the bottom of the pump indicates the direction of flow through the pump.
2. To minimize the possible noise generated by the pump, it is advisable to install anti vibration fixing components on both sides of the pump and between the foundation and the pump body. The mating flange, gasket, bolts, and PJE joint venture are provided as accessories and must be ordered separately. If necessary, when cleaning, repairing, or replacing the pump, isolation valves should be installed on both sides of the pump to prevent system drainage. The installation pipeline of multi-stage centrifugal pumps should avoid air blockage, especially on the suction side of the pump. The pipe should be installed in such a way that any stretching caused by temperature changes will not affect the pump. If the pump is installed on a long pipe, it should be properly supported in front and back as shown.
3. If the multi-stage centrifugal pump is at risk of being blocked by stones, leaves, small branches, etc., measures should be taken to prevent such incidents from happening. Install a filter screen on the suction tube.
4. In some installation situations, if the drainage pipe is already installed horizontally or tilted downwards by the pump, the water inside the pump will or will inevitably flow out at intervals. The pump should be protected from idle rotation of the impeller. Installing a damaged pipe with a vacuum valve near the pump can avoid this situation. The high point of the ring pipe should be at least flush with the connecting plate of the pump's motor. This way, the drainage pipe can drain water separately from the pump, and vice versa.
5. When the drain valve is closed, it is prohibited for the pump to operate, as this can cause an increase in temperature/steam formation inside the pump, leading to pump damage. If there is any danger to the operation of the pump when the drainage room is closed, connect a bypass or drain pipe to the outlet to ensure that a small amount of liquid flows through the pump. A drainage pipe, for example, can be connected to a water tank.
6. The small quantity of QDL and QDLF lightweight multi-stage pumps.

Example of CDLF vertical stainless steel multi-stage pump:

Example of a typical high-pressure scouring system diagram. Galileo Pump recommends this installation method as shown in the figure for situations where "small flow" cannot be guaranteed to pass through the pump.
1. The liquid flow switch of a lightweight multi-stage pump will provide protection to the pump from damage caused by high heat generated during pump operation when the liquid flow is too small.
2. The filter screen of a lightweight multi-stage pump is installed to protect the liquid flow switch in devices used to transport slightly polluted water.
Note: The above measures are not necessary in devices that have stable liquid flow conditions and can ensure low flow rates. In devices with water hammer hazards, a check valve must always be installed at the outlet of the pump. Do not use a quick closing valve, such as a quick closing spray gun, as this type of spray gun can cause water hammer. It affects the connection between the motor and the pump shaft, and in severe cases, it can cause the pump shaft to break.

CDLF vertical stainless steel multi-stage pump electrical connection:

1. Before opening the junction box cover and removing any pump components, the power supply of a lightweight multi-stage pump must be turned off. Electrical connections must be carried out by qualified electricians in accordance with local regulations. The motor junction box must be correctly connected to the power switch wires. The operating voltage and frequency are indicated on the nameplate. Note that the power supply used should be suitable for the motor. The three-phase motor must be connected to a starter with only a protective function.
2. The junction box of the lightweight multi-stage pump can be sequentially turned to 90 ° and stopped in four positions. When needed, a screwdriver can be used to remove the coupling guard, but do not remove the coupling. Unscrew the bolts that secure the motor to the pump. Rotate the motor to the desired position. Tighten the bolts again. Reinstall the coupling guard plate so that it is vertically centered within the recess of the pump head. Electrical connections should be made according to the wiring diagram inside the junction box cover.
Note: Do not start the light multi-stage pump before it is filled with liquid.

Start the CDLF vertical stainless steel multi-stage pump:

1、 When the liquid level of a lightweight multi-stage pump is higher than that of a closed or open system at the pump inlet:
1. Close the drainage isolation valve and loosen the exhaust screw on the pump head.
2. Please pay attention to the direction of the exhaust port and ensure that the water flowing out will not cause harm to people or damage the motor or other components. In hot water installations, special attention should be paid to the risk of burns caused by burning hot water.
3. Slowly open the isolation valve on the suction pipe until a smooth flow of liquid flows out of the exhaust valve.
4. When starting the lightweight multi-stage pump, tighten the exhaust screw and fully open the isolation valve.
2、 When the liquid level of a lightweight multi-stage pump is lower than that of the pump inlet open system:
1. The suction pipe and pump must be filled with liquid and vented before starting the pump.
2. QDL2, 4 (QDLF2, 4, 8, 16)
3. Close the drainage isolation valve. Rotate the bypass valve out slightly towards the stop, as shown in Figure 7.
4. Remove the filling plug and fill the liquid from the filling port until the suction pipe and pump are completely filled with liquid, then tighten the bypass valve again.
5. When starting the lightweight multi-stage pump, replace the filling plug and tighten it firmly.
3、 Check the rotation direction when starting a lightweight multi-stage pump:
1. Do not start the light multi-stage pump to check the direction of rotation until it is filled with liquid.
2. When checking the running direction of the motor, the coupling should not be disassembled for inspection. Because when the coupling is removed, the position of the shaft needs to be adjusted. The correct direction of rotation is indicated by the arrow on the pump head or on the motor fan cover. From the fan, the light multi-stage pump should rotate counterclockwise.
4、 Starting of lightweight vertical multi-stage pumps:
1. Before starting a lightweight multi-stage pump, fully open the isolation valve on the suction side of the pump and leave the isolation valve on the discharge side almost closed.
2. When starting a lightweight multi-stage pump, loosen the exhaust screw on the pump head to allow the pump to exhaust until a smooth flow of liquid flows out of the exhaust hole, and then tighten the exhaust screw.
Attention: The direction of the exhaust hole should be ensured, and the liquid flowing out should not cause injury to people or damage to the motor or other components. In hot water installations, special attention should be paid to the risk of burns caused by burning hot water. When the pipeline system is filled with liquid, slowly open the isolation valve until it is fully opened. When pumping liquid containing air, it is advisable to regularly exhaust the pump. To exhaust the pump, loosen the exhaust screw on the pump head during operation.

Maintenance, start and stop frequency of CDLF vertical stainless steel multi-stage pump:

Maintenance of CDLF vertical stainless steel multi-stage pump:
1. Before starting the operation of a vertical multi-stage pump, it is necessary to verify that there is no power supply to the pump and that the pump cannot suddenly start.
2. The bearings and shaft seals of lightweight multi-stage pumps do not require maintenance. If the pump needs to be drained for a long time, one of the coupling guard plates can be removed and a few drops of silicone oil can be injected into the shaft between the pump head and the coupling. This can prevent the shaft sealing surface from sticking.
3. When installing the coupling guard plates, be sure to align them vertically in the recess of the pump head.
CDLF vertical stainless steel multi-stage pump motor bearing:
4. For motors without lubrication nozzles, maintenance is not required. Motors equipped with lubrication nozzles should be lubricated with high-temperature lithium based grease.
5. If the light multi-stage pump is temporarily suspended for a long time, it is recommended to clean and lubricate the pump and motor once they are not in use.
6. During the frost period, the pump should be left unused and the water should be drained to prevent damage and cracking. Loosen the exhaust screw on the pump head and remove the drain plug on the base to drain the pump. After the water is drained, the removed components should be reinstalled in place or properly stored.
Starting and stopping frequency of CDLF vertical stainless steel multi-stage pump:
Electric motors with a power of less than 4KW for vertical multi-stage pumps shall not exceed 100 starts per hour. The number of starts for other motors shall not exceed 20 per hour.
