LWB explosion-proof vertical sewage pump performance description:
LWB explosion-proof vertical sewage pump is a sewage pump equipped with an explosion-proof motor, which is produced based on our company's original LW vertical sewage pump and according to the customer's application requirements.
1. This sewage pump is a single-suction volute pump. It is equipped with a non-clogging and anti-winding single (double) large-channel impeller with good
passing capacity. The large-channel anti-clogging hydraulic component design greatly improves the dirt passing capacity, and can effectively pass fibrous materials 5 times the pump diameter and solid particles with a diameter of about 50% of the pump diameter.
2. This series of pumps has two structural forms, one is that the motor and the pump are directly coaxial, and the other is connected by a coupling. The motor adopts a standard vertical motor. The pump structure is reasonably designed, equipped with a YX series motor, high efficiency, and energy saving*.
3. The mechanical seal adopts a double-end face series seal, made of hard and corrosion-resistant tungsten carbide, which is durable and wear-resistant, and can make the pump run safely and continuously for more than 8,000 hours.
4. The pump has a compact structure, small size, easy movement, and simple installation.
5. The inlet and outlet installation methods of LWB explosion-proof vertical sewage pump can be placed in 0, 90, 180, 270 according to the customer's pipeline conditions, which is convenient for pipeline connection and can be flexibly arranged according to site requirements.
6. The inlet and outlet diameters of LWB explosion-proof vertical sewage pump are the same, and the diameters can be DN25-DN300 respectively.
7. LWB explosion-proof vertical sewage pump is usually made of cast iron, and can also be customized with various grades of stainless steel materials according to the medium requirements, such as: 201.304.316.316L or other special materials.

Conditions of use:
1. The medium temperature shall not exceed +40℃, intermittent use (maximum 5 minutes) shall be +70℃, the density shall be 1.0～1.3kg/dm3, and the pH value shall be within the range of 5～9.
2. For pumps without internal gravity circulation cooling system, the motor part shall not exceed 1/2 of the liquid surface.
3. In general, the pump must be used within the use head range to ensure that the motor is not overloaded. If it is required to be used within the full head range, it should be specified separately when ordering so that the manufacturer can manufacture it.
4. During operation, the motor current shall not exceed the rated current of the motor.
