LW Type Vertical Non clogging Sewage Pump Product Overview:

The LW type vertical non clogging sewage pump is developed by introducing foreign * technology and absorbing and transforming it. All performance indicators have reached the standard level of similar products. Due to the use of * single (double) channel impellers, the discharge capacity is strong and it can effectively pass through 5 times the diameter of the pump and solid particles with a diameter of 50% of the pump diameter. The dynamic seal adopts two sets of special hard alloy mechanical seal devices made of cast iron and stainless steel.
The LW type vertical non clogging sewage pump is a single suction volute pump equipped with non clogging and anti winding single (double) large channel impellers, which have good passing capacity.
This series of pumps has two structural forms, one is that the motor is directly coaxial with the pump, and the other is that it is connected by a coupling, and the motor adopts a standard vertical motor. The structural diagram is as follows, and each structural form has two types of base connection forms. One is the inlet horizontal suction, which has a corner function and can be placed at 0 °, 90 °, 180 °, 270 ° according to usage requirements for pipeline connection. The other is the inlet axial suction, which is convenient for vertical installation.

[LW type vertical unobstructed sewage pump] Product features:

1. Adopting a double blade impeller structure greatly improves the ability of pollutants to pass through
2. The mechanical seal adopts a new type of friction pair and operates in the oil chamber at * position;
3. The overall structure is compact, small in size, low in noise, energy-saving *, easy to maintain, and convenient for users to replace;
4. The automatic control cabinet can automatically control the pump's over movement and stop according to the required liquefaction changes, without the need for dedicated personnel to supervise, making it extremely convenient to use;
5. Installation methods can be equipped according to user needs, providing convenience for installation and maintenance, and people can enter the sewage pit without having to do so;
6. Can be used within the design scope while ensuring that the motor does not overload;
7. If the pump is equipped with an outdoor motor, there is no need to build a pump room, and it can be directly installed and used outdoors to save costs;
