    Product Overview:

    ZW self-priming sewage pump is a type of pump that integrates self-priming and sewage functions. It can be used like ordinary clean water self-priming pumps without the need to install a bottom valve, without the need to irrigate water. It can also suck dirt, sediment, large particles containing 60% of the diameter of the outlet diameter and fiber length 1.5 times the diameter of the impeller. Waste mineral impurities, manure treatment and engineering sewage and colloidal liquid reduce labor intensity of manpower, and it is easy to install and use, and requires less maintenance.

    Scope of application:

    Suitable for chemical, petroleum, pharmaceutical, mining, papermaking, fiber, pulp, textile, food, power plant and municipal sewage works, public facilities sewage, river pond breeding and other industries.

    1. Ambient temperature ≦ 50 C, medium temperature ≦ 100 C.
    2. The PH value of the medium is 6-9 for cast iron and 2-13 for stainless steel.

    3.Media weight does not exceed 1240 kg / m3

    4. Self-priming height cannot exceed the specified value of 4.5-5.5 meters, and the length of the suction pipe is ≦ 10 meters.

    5. Passing capacity The diameter of suspended particles is 60% of the pump diameter, and the fiber length is 5 times the pump diameter.

    Product advantages:

    1. Strong drainage capacity: The anti-blocking design of the impeller ensures that the pump is not easy to block.

    2. Good self-priming performance: self-priming height is higher than general self-priming pumps 1 meter , And the self-priming time is shorter.

    Technical parameters:

    Flow: 5 -800m3 / h;

    Head: 12 -60m ;

    Motor power: 2.2-55KW;

    Speed: 1450-2900r / min;

    Caliber: φ25-φ300;

    Medium temperature: ≤ 100 ℃ ;

    Self-priming height: 4.5 -5.5m .

    6.Troubleshooting

    malfunction

    the reason

    Method of exclusion

    No water from the pump

    1. No or insufficient liquid storage in the pump body

    2. Leakage in the suction line

    3. The voltage is too low

    4. The suction stroke is too high or the suction line is too long

    5. Excessive mechanical seal leakage

    Increase foot

    2. Eliminate air leakage in the pipeline

    3. Adjust the voltage

    4. Reduce the suction stroke or shorten the pipeline

    5. Repair or replacement

    Pump out of water

    1. Impeller flow path or suction line is blocked due to improper use

    2. Heavy impeller wear

    3.Insufficient power speed is too low

    1. Eliminate blockages

    2. Replace the impeller

    3.Adjust to rated speed

    Pump chirps and excessive vibration

    1. The feet are unstable.

    2. Serious bearing wear

    3.Pumps and motors have different axes

    Reinforcement

    2. Replace the bearing

    3. Adjust coaxiality

    Bearing temperature is too high

    1. Grease deteriorates or dries

    2.Bearing damage

    1. Change the grease

    2. replace

    Pump leak

    1. The bolts are loose

    2. Frequency of seal wear

    1. fasten

    2. replace
