The KQZF corrosion-resistant strong self-priming pump is a high-performance, corrosion-resistant pump independently designed and developed by Shandong Kaiquan Pump&Valve Co., Ltd. based on market research and user needs. This type of pump has two structures: magnetic drive and mechanical seal. Its flow range is 2-8m for 3 hours and head is 45-12m. It has a wide performance range, fast gas separation speed, short self-priming time, high suction stroke (up to 7 meters), compact structure, strong reliability, and other unparalleled advantages compared to other self-priming pumps. It can frequently use self-priming function. This pump is particularly suitable for conveying small volumes and continuously changing the drum medium (commonly known as pumping), solving a major problem in the transportation of media in this industry.

Installation method and connection requirements:

1. Prepare the concrete foundation according to the basic dimensions and embed the anchor bolts. Place the unit on the foundation, align the pump horizontally, and tighten the foundation bolts. The pump should be located as close as possible to the water tank.

2. The diameter of the inlet pipe of the pump shall not exceed the specified requirements, and the total length of the inlet pipe shall not exceed 5m. The shorter the pipe, the better, provided that the requirements are met. A filter screen must be installed at the bottom of the inlet pipe to prevent excessive particles or debris from entering the pump body and damaging the impeller or affecting the pump's operation. The filtration area should be greater than 3-4 times the cross-sectional area of the pipeline.

3. Valves must be installed in the outlet pipeline of the pump to regulate the flow rate, so that the pump can operate at the specified flow rate and prevent the pump from being unable to operate after exceeding the limit. The diameter of the outlet pipe shall not be less than the specified requirements. The total length of the outlet pipe must be greater than 1.5 times the total length of the inlet pipe, and it is better to be longer if possible.

4. The various parts connected to the inlet and outlet pipelines must be tight and leak free, otherwise it will affect the self-priming function and the normal operation of the pump.

Usage and maintenance instructions:

1. Self suction magnetic pumps are strictly prohibited from conveying media containing solid particles or easily crystallized materials. Continuous operation is not allowed with the discharge outlet closed, and the minimum flow rate must be maintained.

2. When installing pipelines, connect the inlet pipe first, fill it with liquid, and then connect the outlet pipe.

3. After installation, connect the power supply and check whether the pump rotates flexibly by jogging, and whether the motor direction is consistent with the direction mark.

4. Open the outlet valve by about one-third to start the self-priming pump (i.e. open the valve to start). After suction, slowly adjust the outlet valve to ensure that the pump works normally under rated conditions.

5. During infusion, the flow rate, head, and self-priming height must be controlled within the specified range, otherwise it may cause the pump to malfunction.

6. Self priming pumps cannot transport media that generate large amounts of bubbles, nor can they transport gas-liquid mixtures.

7. When transporting media that are prone to crystallization, if the pump is stopped for a period of time and not in use, the pump chamber must be flushed to prevent residual crystallization media and prevent damage when the pump is restarted after crystallization; When reusing, add the required liquid before self suction.

8. When transporting non crystalline media, if the pump is stopped for a long time before use, check whether the liquid in the pump body is sufficient before starting, and make up for it before self suction.

9. The self-priming height can be calculated using a simple formula: self-priming height in clear water/medium density=actual self-priming height.
