FLOWMONSTER LD Series Stainless Steel SUS 316L Triplex Plunger Pump Belt Drive High Pressure Plunger Pump for Industrial Desalination 150-250Bar Seawater reverse osmosis purification Plunger Pump High Flow Plunger Pump 30-72LPM Ceramic Plunger Pump

Excellent pump with suitable flow and pressure, you can use it for chemical industry, sea water desalination, corrosion fluid and spraying. With the help of regulator valve, you could control the pressure by yourself. Stainless steel pump head and cast iron crank box make pump durable, stainless steel is suitable for desalination. The checking valve and ceramic plunger inside of pump are easily detached and have good performance. The crank shaft of pump is made by excellent alloy, it is strong and owns long use life. You can observe capacity of oil by oil mirror. When you first use our pump, you should change oil after using the pump for 50 hours. Then you should change oil after pump being used 500 hours. We will offer after-sale service within 1 year and offer service of providing spare part package.

Instructions for use

1. The pump should be installed on a flat base less than 15 degrees to ensure the best lubrication conditions

2. Confirm the inlet size of the high-pressure pump piping. The inlet pipe diameter should be 1.5-2 times the inlet size of the pump. The inlet and outlet of the pump must be equipped with hoses to avoid pressure and fluctuations generated by the system. It is best to install accumulators to avoid bending of pipes.

3. The water supply pressure should be 1.5-8kg/cm². The water supply temperature is below 70 degrees. The water supply system of the high-pressure pump must avoid the entry of air to ensure that the pump parts are not damaged.

Direction of rotation: The direction of rotation of the high-pressure pump is the direction in which the top of the pulley must face the pump head.

4. Before starting the motor-pump system, the following must be done

1). Check whether the crankcase lubricating oil is normal. If the oil level indicator of the gear box has only one engraved line, the oil level cannot be lower than the engraved line, but not higher than the engraved line 5mm. If the oil level indicator of the gear box has two Each line, the oil level is between the two lines.

2) Confirm that the valves of all pipes have been opened, and the medium can flow into the inlet of the pump and exhaust the air inside the system.

3) The operation of the high-pressure pump is not allowed to exceed the specified pressure, flow and speed.

4) Before spraying, the high-pressure nozzle should confirm whether the spray direction is safe. If there are unsafe factors, they should be eliminated in time to ensure safe production.

5. In order to remove the water in the pump to facilitate the placement in the freezing point environment, the pump can run for no more than 10 seconds under the condition of no water inlet.

6. For the system where the overflow valve is installed, the overflow pipe must be a hose. The overflow pipe should not be connected to the water inlet of the pump, but should be connected to the water tank or sewer.

7. When used for water storage tank, the suction line should use a hose of less than 3 meters, and the water level should be set higher than the height of the pump. If the water supply pressure does not reach the required pressure, it is recommended to use a booster pump.

8. Clean water should be used for the water supply, and a filter should be used on the supply line to prevent the inhalation of foreign objects.

9. Before operating the high-pressure pump, loosen the pressure regulating valve, and then gradually increase the pressure as needed after operation.

10. Lubricating oil should use SAE20W-50 or the same level of lubricating oil.

11. Lubricating oil should be replaced after 50 hours of initial use, and every 500 hours thereafter.

12. The water inlet filter should be regularly checked and cleaned.

13. All moving parts of the plunger pump must not be in a dry state.

14. High-pressure pumps are not allowed to use acidic, alkaline or corrosive liquids.
